Ethnoveterinary herbal remedies used by farmers in four north-eastern Swiss cantons (St. Gallen, Thurgau, Appenzell Innerrhoden and Appenzell Ausserrhoden)

Farmers' knowledge in the Swiss canton Valais: cultural heritage with future significance for European veterinary medicine?

BACKGROUND

The demand for natural product-based treatment options for livestock is increasing by animals' owners, veterinarians and policy makers. But at the same time, the traditional knowledge about it is at risk of falling into oblivion in Europe. The present study recorded this knowledge for the linguistically and geographically interesting Swiss canton of Valais.

METHOD

Open, semi-structured interviews were used to collect detailed information on formulations and applications, including plant species and natural substances, origin of material, extraction and preparation of herbal products, indication and type of application, dosage, sources of knowledge, frequency of usage and self-assessment of the treatment.

RESULTS AND DISCUSSION

In the course of 43 interviews, 173 homemade single species herbal remedy report (HSHR) were recorded. They included 53 plant species from 30 botanical families. Plant species from the botanical families of Asteraceae, Rubiaceae and Cupressaceae were mentioned the most, while the most frequently documented plant species were Coffea arabica L., Juniperus sabina L., Arnica montana L. and Matricaria chamomilla L. For the 173 HSHR, a total of 215 uses were mentioned, most of which were for the treatment of gastrointestinal and metabolic disorders, followed by skin lesions and genito-urinary tract problems. Regional peculiarities emerged, such as the use of Leontopodium alpinum Cass. for diarrhea in the French-speaking Valais, while Matricaria chamomilla and Camellia sinensis L. were used in the German-speaking part instead. In comparison with other regions of Switzerland, 10 plants were reported for the first time, including Juniperus sabina with 18 use reports.

CONCLUSION

The daily use on farms and the high satisfaction of farmers with homemade herbal remedies demonstrate their high practical relevance. In conclusion, the traditional regional knowledge about the use of medicinal plants is not only a cultural heritage worth protecting, but also an essential resource for the further development of European veterinary medicine.

[Homemade herbal remedies - tradition with practical relevance]

OBJECTIVE

The preparation of homemade herbal remedies has always been practiced by animal keepers and is still employed in farm animals today. In order to document this practice, an ethnoveterinary study was conducted in Bavaria in 2018-2021.

MATERIAL AND METHOD

The farmers were interviewed on site and the reported recipes were documented in detail and, where possible, also carried out during the interviews. The plant parts used were weighed using a laboratory balance in order to be able to calculate a daily dose per animal or the concentration in the end product for as many of these traditional use reports (UR) as possible.

RESULTS

A total of 716 recipes for 884 UR were named in the 77 interviews by the participating farmers. Two thirds (69%) of the formulations mentioned consisted of one or more medicinal plants and 31% dealt with other natural home remedies (honey, vinegar, etc.). Overall, the farmers surveyed preferred the use of single plants in their formulations. Most UR were for cattle (77% of all reports). These traditional remedies are most often used in Bavarian stables for the treatment and prophylaxis of gastrointestinal diseases and metabolic disorders. Furthermore, there was a high correspondence of the medicinal plants used with described UR from two historical reference books. The study participants used their homemade herbal remedies with a high degree of satisfaction and thereby act within the scope of their own responsibility as farmers.

CONCLUSION AND CLINICAL RELEVANCE

This traditional knowledge of herbal preparations containing active ingredients, which has been passed on for generations, may also be a good starting point for a phytotherapeutic supplement in the treatment of farm animals in veterinary practice. Pharmaceutical and feed law framework conditions must be adhered to.

Potential factors causing failure of whole plant nettle (Urtica cannabina) silages

Introduction

Nettle is kind of new feed resources and benefit for animal production. However, a few studies observed that quality of nettle silage was poor under naturally fermentation. Consider of microbial activity was the mainly factors for fermentation characteristics of silage.

Methods

Thus, the present study investigated the potential factors causing nettle silage failure through metabolome and bacterial community composition analyses during ensiling.

Results

During ensiling, the pH was >6.22, and water-soluble carbohydrate and organic acid contents stabilized after 7 d. At the genus level, Enterococcus, Weissella, and Pediococcus were the dominant bacteria (relative abundance were 30.06-39.39, 17.29-23.34, and 3.13-7.22%, respectively), with stable trends, whereas Lactococcus and Enterobacter relative abundance decreased significantly over time (relative abundance were 5.68-13.96 and 3.86-24.1%, respectively). Lactobacillus relative abundance was <1% during the entire ensiling period, and malic acid metabolic pathway was the most important pathway. Enterococcus, Pediococcus, and Weissella were negatively correlated with malic acid, with Lactobacillus displaying an opposite trend.

Discussion

The results suggested that Lactobacillus activity was the lowest among lactic acid bacteria (LAB) during ensiling, which is the main reason for nettle ensiling failure, and attributable to a low capacity to compete for fermentation substrates such as malic acid against other LAB during ensiling. Additionally, anti-bacteria activity of nettle probably inhibited Enterobacter activity during ensiling. Present study probably given a solution for improve nettle silage quality through addition with malic acid.

Ethnoveterinary use of plants and its implication for sustainable livestock management in Nepal

Traditional herbal remedies are used worldwide for treating both human and livestock health issues. Though such uses are relatively well-explored for humans, the ethnoveterinary uses of plant-based remedies in the healthcare choices of livestock in Nepal and associated knowledge are largely ignored. This is important as sustainable livestock production is an emerging issue. This study reviews the existing ethnobotanical studies conducted in Nepal and reports the use of 393 species of plants from 114 botanical families in ethnoveterinary practices. Thirty-four different ailments were treated using these plants. The present review revealed that Nepal has a rich diversity of ethnoveterinary plants. This study shows that traditional herbal medicine plays a significant role in meeting the livestock healthcare needs of Nepali farmers and hence is a viable practice. The study also contributes a wealth of knowledge about ethnoveterinary practices for further planning and use. This will provide an option for livestock farmers who cannot afford allopathic medicine or who are not allowed to use such medicine under organic farming schemes that are likely to be a part of sustainable livestock farming programs in Nepal soon.

Inventorization and Consensus Analysis of Ethnoveterinary Medicinal Knowledge Among the Local People in Eastern India: Perception, Cultural Significance, and Resilience

Livestock is the main backbone of the rural economy of an agriculture-based country like India. To mitigate the economic loss due to livestock’s poor performance and illness, folk phytotherapy for livestock healthcare is still actively practiced in India. Literature survey revealed that the laterite region of eastern India, characterized by its cultural, ethnic, and biological diversities, as well as topographical uniqueness, lacks comprehensive information on ethnoveterinary medicinal knowledge. The objective of the present study includes documentation of traditional knowledge of ethnoveterinary medicine (EVM) from the northern laterite region in eastern India. Ethnoveterinary medicinal data were collected using a semi-structured questionnaire, free listing, and focus group discussions. The factor for informants’ consensus (Fic), fidelity level (FL), and cultural value (CV) index have been employed for quantitative analyses. Jaccard index (JI) was used to check the knowledge similarity. Altogether, 1,234 citations were made by 132 participants. In total, 232 recorded ethnomedicinal species are used for preparing 306 remedies to treat 79 health disorders of livestock. Recorded species are distributed in 92 families, and Fabaceae is identified as the most medicinally diversified. Uses of 24 angiospermic taxa, one pteridophyte, and two fungal species were exclusively new to the existing inventory of Indian traditional ethnoveterinary medicine. In 20 disease categories, the informant consensus (Fic) value ranges from 0.4 to 0.83. According to the FL value and use-mention factor, 23 EVM plants have been identified as the most important species in the respective disease categories. Value of CV index highlighted nine species as culturally most significant (CV ≥ 0.0025 and frequency of citation ≥20) in the laterite region of eastern India. A large extent of recorded data are quite worthy for the Indian folk veterinary medicinal repository. A handful of new data reported here and statistically justified culturally most significant species will provide the golden opportunity for bioprospecting research.

An ethnoveterinary study of wild medicinal plants used by the Kyrgyz farmers

ETHNOPHARMACOLOGICAL RELEVANCE

In their centuries-old nomadic life, since their livestock was the backbone of their lives, the Kyrgyz people used a variety of wild medicinal plants for ethnoveterinary practices. However, the plants used for the treatment of livestock ailments never have been recorded, except rarely in local publications. In this study, we present the HSHR (homemade single species herbal remedy reports), their methods of preparation and application, and the livestock ailments for which these remedies were used.

AIMS

The collect data from the five different high-altitude valleys of the Kyrgyz Republic on common HSHR used for the treatment of the livestock ailments and describe their preparation procedure, administration, and target animal species.

MATERIALS AND METHODS

The plant species mentioned for ethnoveterinary use were collected from five different high-altitude valleys (pastures) in the Kyrgyz Republic during 2016 and 2018. Data were gathered with the help of dialog partners (experienced local shepherds, farmers and veterinarians) through semi-structured interviews. In total, 166 dialog partners were interviewed. The special characteristics of HSHR mentioned for ethnoveterinary use and practices were documented. Plant samples and voucher specimens were collected for taxonomic identification, and preserved for future reference.

RESULTS

A total of 2388 HSHR referred to 66 plant species mentioned for ethnoveterinary use belonging to 27 families and 49 genera. According to the data, species of the family Asteraceae were most frequently used HSHRs in the Kyrgyz ethnoveterinary practice (599 HSHR, 25%), followed by Polygonaceae (166 HSHR, 7%), Lamiaceae (141 HSHR, 6%), Ranunculaceae (121 HSHR, 5%), Nitrariaceae (119 HSHR, 4.9%), Apiaceae (113 HSHR, 4.7%), Cupressaceae (111 HSHR, 4.6%), Urticaceae (100 HSHR, 4.2%), Gentianaceae (92 HSHR, 3.8%), Amaranthaceae (87 HSHR, 3.6%). A total of 2785 UR (use reports) were collected for the 2388 HSHR. Infection diseases (572 UR, 20.5%), parasitic diseases (531 UR, 19%), gastrointestinal disorders (523 UR, 18.77%) and wounds (522 UR, 18.74%) were almost evenly reported indications. The largest number use reports (UR) were for cattle (967 UR, 34.7%) and horses (919 UR, 33%), followed by 607 UR (21.8%) for sheep and 292 UR (10.48%) for other domestic animals, including dogs (106 UR, 3.8%), goats (103 UR, 3.69%) and donkeys (83 UR, 2.98%).

CONCLUSION

In this study, we identified the folk ethnoveterinary knowledge of the HSHR used by the Kyrgyz farmers in their daily veterinary practice. All the characterized HSHR are of value to the local animal breeders. This knowledge has previously been limited to local shepherds, farmers and vets. Many of these need scientific confirmation using modern methods of phytochemistry and pharmacology.

Ethnoveterinary study of galactogenic recipes used by ruminant breeders to improve milk production of local cows in Benin Republic

ETHNOPHARMACOLOGICAL RELEVANCE

In Benin, traditional recipes are used to improve livestock dairy performance, but they are not sufficient documented. The study aimed to inventory the galactogenic recipes used by herders to improve production in cow farming.

AIM OF THE STUDY

The study aimed to inventory the galactogenic recipes used by herders to improve production in cow farming.

MATERIAL AND METHODS

We conducted semi-structured interviews among 65 peuls camps, 4 bioclimatic zones, and 565 farmers dialogue partners, including agro-pastoralist, healers and pastoralists from the rainy season April and May 2019. Detailed information about homemade herbal remedies of galactogenic recipes (plant species, plant part, manufacturing process) and the corresponding use reports (dialogue partner, category of use and route of administration) was collected. Then other to classify the various recipes identified into homogeneneous groups according to their effectiveness in stimulating milk, a numerical classification was carried out on the recipes taking into account the milk gain.

RESULTS

They showed that Peuls and Gandos sociocultural groups have a better knowledge of galactogenic recipes. Of the 295 recipes inventoried, 102 frequently cited recipes were divided into two groups. Group 2, consisting of 16 recipes, had a significantly (p < 0.001) higher milk yield than group 1. Vigna unguiculata (L.) Walp. and Arachis hypogaea L. were the main ingredients of the recipes (respectively 56 and 31% of incorporation rate). The composition of the recipes varied according to the agro-ecological zones. Herders in Northern Benin used more recipes based on Bobgunnia madagascariensis (Harms) J.H.Kirkbr. & Wiersema, Saba comorensis (Bojer ex A.DC.) Pichon and Euphorbia balsamifera Aiton. Those in Southern Benin mainly used recipes based on Gardenia aqualla associated with Vigna unguiculata (L.) Walp or Arachis hypogaea L.. To improve the effectiveness of galactogenic recipes, socio-cultural and magical-religious practices are used when procuring the plant material to be used, preparing the galactogen and administering the recipe to the animals. These include pronounced incantations or recited Koranic verses. The most commonly used route of administration is the oral route with an average treatment duration not exceeding 5 days.

CONCLUSION

The study reveals that the majority of breeders (90%) opt for the use of galactogenic plants rather than synthetic products to improve milk production.

Medicinal Plants for Prophylaxis and Therapy of Common Infectious Diseases In Poultry-A Systematic Review of In Vivo Studies

Medicinal plants for prophylaxis and therapy of common infectious diseases in poultry have been studied for several years. The goal of this review was to systematically identify plant species and evaluate their potential in prophylaxis and therapy of common diseases in poultry caused by bacteria and gastrointestinal protozoa. The procedure followed the recommendations of the PRISMA statement and the AMSTAR measurement tool. The PICOS scheme was used to design the research questions. Two databases were consulted, and publications were manually selected, according to predefined in- and exclusion criteria. A scoring system was established to evaluate the remaining publications. Initially, 4197 identified publications were found, and 77 publications remained after manual sorting, including 38 publications with 70 experiments on bacterial infections and 39 publications with 78 experiments on gastrointestinal protozoa. In total, 83 plant species from 42 families were identified. Asteraceae and Lamiaceae were the most frequently found families with Artemisia annua being the most frequently found plant, followed by Origanum vulgare. As compared to placebo and positive or negative control groups, antimicrobial effects were found in 46 experiments, prebiotic effects in 19 experiments, and antiprotozoal effects in 47 experiments. In summary, a total of 274 positive effects predominated over 241 zero effects and 37 negative effects. Data indicate that O. vulgare, Coriandrum sativum, A. annua, and Bidens pilosa are promising plant species for prophylaxis and therapy of bacterial and protozoal diseases in poultry.

Traditional Applications of Tannin Rich Extracts Supported by Scientific Data: Chemical Composition, Bioavailability and Bioaccessibility

Tannins are polyphenolic compounds historically utilized in textile and adhesive industries, but also in traditional human and animal medicines or foodstuffs. Since 20th-century, advances in analytical chemistry have allowed disclosure of the chemical nature of these molecules. The chemical profile of extracts obtained from previously selected species was investigated to try to establish a bridge between traditional background and scientific data. The study of the chemical composition of these extracts has permitted us to correlate the presence of tannins and other related molecules with the effectiveness of their apparent uses. The revision of traditional knowledge paired with scientific evidence may provide a supporting background on their use and the basis for developing innovative pharmacology and food applications based on formulations using natural sources of tannins. This traditional-scientific approach can result useful due to the raising consumers' demand for natural products in markets, to which tannin-rich extracts may pose an attractive alternative. Therefore, it is of interest to back traditional applications with accurate data while meeting consumer's acceptance. In this review, several species known to contain high amounts of tannins have been selected as a starting point to establish a correlation between their alleged traditional use, tannins content and composition and potential bioaccessibility.

Plant and natural product based homemade remedies for veterinary uses by the Peul community in Benin

ETHNOPHARMACOLOGICAL RELEVANCE

Across Africa, Peul community typically rely on plant-based veterinary knowledge to manage common livestock health problems. Unfortunately, their nomadic life-style being affected by conflicts, land tenure constraints, and drought, they have been shifting to a sedentary life. The process of their settlement led to the erosion of the vast ethnoveterinary skills they had acquired over centuries and forced them to replace the plant and other species they used by commercial products.

AIM OF THE STUDY

1) To collect comprehensive data from the Benin Peul community on common plant-based remedies used to treat livestock diseases and document their preparation and administration. 2) To evaluate the differences and consensus among the Peul community across ecological regions in Benin.

MATERIALS AND METHODS

We conducted semi-structured interviews among 88 Peul camps, three (03) bioclimatic zones, and 225 transhumant dialog partners, including agro-pastoralists, healers and pastoralists from mid-July to end of December 2015. Detailed information about homemade herbal remedies (plant species, plant part, manufacturing process) and the corresponding use reports (target animal species, category of use and route of administration) was collected.

RESULTS

A total of 418 homemade remedies were reported, of which 235 involved only one plant species (Homemade Single Species Herbal Remedy Reports; HSHR). Information on a total of 310 use reports (UR) were mentioned for the 235 HSHR, and they included 116 plant species belonging to 39 botanical families. Among them, 229 UR were indicated for cattle, 43 UR for poultry, and 38 UR for sheep and goats. The most cited plant species were Khaya senegalensis (19 HSHR; 8.08%), Parkia biglobosa (14 HSHR; 5.95%), Euphorbia unispina (11 HSHR; 4.68%), and Anogeissus leiocarpus (6 HSHR; 2.55%). The URs were indicated for the treatment of viral, parasitic and bacterial diseases but also for multifactorial disorders like diarrhoea, fever, threatened abortion, agalactia etc. The number of plants referred to HSHR decreased from Sudanian to Guineo-congolian zones in concordance with the presence of Peuls.

CONCLUSION

The Peul community holds a huge ethnoveterinary knowledge, which needs to be documented, valorised, and promoted. It appears vital to assess phytochemical and pharmacological properties of the most reported species, and their availability across the ecological zones in order to ensure their sustainable use and before this indigenous knowledge disappears completely.

A multicomponent herbal feed additive improves somatic cell counts in dairy cows - a two stage, multicentre, placebo-controlled long-term on-farm trial

In contrast to natural and historical diets of wild and domesticated ruminants, the diversity of plant species is limited in diets of modern dairy cows. Are "production diseases" linked to this? We conducted a trial to test the effects of a multicomponent herbal feed additive (HFA) on health, performance and fertility traits. A dose-finding study (DF) with 62 cows on 11 commercial farms compared a low (50 g) and a high (100 g) dose of HFA (HFA-50, HFA-100) with a placebo (PL). In a subsequent field trial (FT) with 280 cows on 30 commercial farms, HFA-100 was compared to PL. Cows were randomly assigned to HFA and PL groups and received HFA or PL individually daily from 14 days pre- to 300 days post-calving. Data were analysed with mixed effects models. No differences between HFA and PL were found regarding performance, body condition score and overall culling rates. A tendency towards lower milk urea for HFA-100 compared to PL (p = .06) was found in DF. HFA significantly reduced elevated milk acetone observations (≥10 mg/L) in the first 10 lactation weeks (HFA-100: 4%; HFA-50: 4%; PL: 12%) in DF. HFA-50 significantly reduced lameness incidence (HFA-100: 11%; HFA-50: 2%; PL: 14%) in DF. Calving intervals were 15 days shorter in HFA compared to PL in both trials, which could be confirmed by tendency (p = .07) in FT. In both trials, the proportion of test days with elevated somatic cell score (≥3.0) was significantly lower in HFA compared to PL (DF: HFA-100: 40%, HFA-50: 45% and PL: 55%; FT: HFA-100: 38% and PL: 55%) which is also reflected by tendency (p = .08) in lower culling rates due to udder diseases in FT. HFA showed no negative impact on any of the measured parameters. The effects of HFA indicate a potential of phytochemically rich and diverse feed additives for dairy cows' nutrition and physiology.

Ethnoveterinary knowledge of farmers in bilingual regions of Switzerland - is there potential to extend veterinary options to reduce antimicrobial use?

ETHNOPHARMACOLOGICAL RELEVANCE

In the pre-antibiotic era, a broad spectrum of medicinal plants was used to treat livestock. This knowledge was neglected in European veterinary medicine for decades but kept alive by farmers. Emergence of multidrug resistant bacterial strains requires a severely restricted use of antibiotics in veterinary medicine. We conducted a survey on the ethnoveterinary knowledge of farmers in the bilingual (French and German speaking) Western region of Switzerland, namely the cantons of Fribourg, Neuchâtel and Jura, and in the French speaking part of the canton of Bern.

AIM OF THE STUDY

To find out whether differences exist in plants used by farmers in French speaking and bilingual regions of Switzerland as compared to our earlier studies conducted in Switzerland. Additional focus was on plants that are used in diseases which commonly are treated with antimicrobials, on plants used in skin afflictions, and on plants used in animal species such as horses, for which the range of veterinary medicinal products is limited.

MATERIAL AND METHODS

We conducted in 2015 semistructured interviews with 62 dialog partners, mainly cattle keeping farmers but also 18 horse keeping farmers. Of these, 41 were native French (FNS) and 21 native German speakers (GNS). Detailed information about homemade herbal remedies (plant species, plant part, manufacturing process) and the corresponding use reports (target animal species, category of use, route of administration, dosage, source of knowledge, frequency of use, last time of use and farmers satisfaction) were collected.

RESULTS

A total of 345 homemade remedies were reported, of which 240 contained only one plant species (Homemade Single Species Herbal Remedy Reports; HSHR). A total of 289 use reports (UR) were mentioned for the 240 HSHR, and they comprised 77 plant species belonging to 41 botanical families. Of these, 35 plant species were solely reported from FNS, 20 from GNS, and 22 from both. Taking into account earlier ethnoveterinary studies conducted in Switzerland only 10 (FNS) and 6 (GNS) plant species connected with 7% of FNS and GNS UR respectively were "unique" to the respective language group. The majority of the UR (219) was for treatment of cattle, while 38 UR were intended to treat horses. The most UR were for treatment of gastrointestinal and skin diseases. The most frequently mentioned plants were Linum usitatissimum L., Coffea L., Matricaria chamomilla L., Camellia sinensis (L.) Kuntze, and Quercus robur L. for gastrointestinal diseases, and Calendula officinalis L., Hypericum perforatum L. and Sanicula europaea L. for skin afflictions.

CONCLUSION

No clear differences were found between the medicinal plants used by French native speakers and German native speakers. Several of the reported plants seem to be justified to widen the spectrum of veterinary therapeutic options in gastrointestinal and dermatological disorders in cattle and horses, and to reduce, at least to a certain degree, the need for antibiotic treatments. Our findings may help to strengthen the role of medicinal plants in veterinary research and practice, and to consider them as a further measure in official strategies for lowering the use of antibiotics.

Corporate social responsibility, reputation and visitors’ commitment as resources for public policies’ design for protected areas for tourism sustainable exploitation

Purpose

This paper aims to examine the influences of perceived corporate social responsibility (pCSR) over the brand reputation (BR) and the visitor commitment of protected areas (PAs) of Quintana Roo visitors, to create useful resources for the design of public policies in accordance to the expectations of the stakeholders from a sustainable development (SD) approach.

Design/methodology/approach

A cross-sectional causal multistage research was conducted. First, a literature review was performed to develop the hypotheses and the theoretical model on the basis of the paradigm of “sustaincentrism.” Afterwards, the model was empirically contrasted with data gathered from a representative sample of 440 real visitors of three Mexican PAs. The data covariance structures were examined through confirmatory factor analysis and structural equation modeling.

Findings

The results of the study undercover the direct and indirect effects that pCSR has over the BR and the commitment of PA’s visitors, evidencing their relevance as valuable resources for the design of public policies.

Originality/value

This research manifests the capacity to benefit from the studied variables as resources for the design and implementation of public policies that incorporate the development and execution of SD-attuned CSR programs able to create competitive advantages required by PA to their sustainable tourism exploitation.

Medicinal plants as therapeutic options for topical treatment in canine dermatology? A systematic review

Background

Medicinal plants have been used traditionally since centuries for wound care and treatment of skin diseases both in human and animals. Skin diseases are one of the most common reasons for owners to take their dog to the veterinarian. The demands for treatment and prophylaxis of these diseases are broad. A wide range of bacteria including antibiotic-resistant bacteria can be involved, making the treatment challenging and bear an anthropo-zoonotic potential. The aim of this review is to systematically evaluate based on recent scientific literature, the potential of four medicinal plants to enrich the therapeutic options in pyoderma, canine atopic dermatitis, otitis externa, wounds and dermatophytosis in dogs.

Results

Based on four books and a survey among veterinarians specialized in phytotherapy, four medicinal plants were chosen as the subject of this systematic review: Calendula officinalis L. (Marigold), Hypericum perforatum L. agg. (St. John’s Wort), Matricaria chamomilla L. (syn. Matricaria recutita L., Chamomile) and Salvia officinalis L. (Sage). According to the PRISMA statement through literature research on two online databases a total of 8295 publications was screened and narrowed down to a final 138 publications for which full-text documents were analyzed for its content resulting in a total of 145 references (21 clinical, 24 in vivo and 100 in vitro references).

Conclusions

All four plants were proven to have antibacterial and antifungal effects of a rather broad spectrum including antibiotic-resistant bacteria. This makes them an interesting new option for the treatment of pyoderma, otitis externa, infected wounds and dermatophytosis. Marigold, St. John’s Wort and Chamomile showed wound-healing properties and are thus promising candidates in line to fill the therapeutic gap in canine wound-healing agents. St. John’s Wort and Chamomile also showed anti-inflammatory and other beneficial effects on healthy skin. Due to the wide range of beneficial effects of these medicinal plants, they should be taken into account for the treatment of dermatologic diseases in dogs at least in future clinical research.

Ethnoveterinary contemporary knowledge of farmers in pre-alpine and alpine regions of the Swiss cantons of Bern and Lucerne compared to ancient and recent literature - Is there a tradition?

ETHNOPHARMACOLOGICAL RELEVANCE

The term "traditional" is well established in European (human) medicine and even appears in recent European regulations on herbal medicinal products connected to a simplified registration. In contrast, a scientific discussion of a Traditional European Veterinary Herbal Medicine is still lacking in spite of a rising interest, in herbal medicine for animals in particular of veterinarians. There is only limited systematic ethnoveterinary research in Europe, with exception of the Mediterranean region, Switzerland and Austria. We conducted a survey on the ethnoveterinary knowledge of farmers in the pre-alpine and alpine regions of the Swiss cantons of Bern and Lucerne. We compared the findings with earlier studies conducted in Switzerland and with recent and past human and veterinary medicinal literature.

AIM OF THE STUDY

We wanted to know to what extent (dependent to different definition of the term "traditional") the ethnoveterinary knowledge of Swiss farmers could be considered as "traditional" in a European veterinary medicinal context.

MATERIAL AND METHODS

Semistructured interviews with 44 dialog partners, mainly smallholder cattle farmers, were conducted in 2014. Detailed information about homemade herbal remedies (plant species, plant part, manufacturing process) and the corresponding use reports (target animal species, category of use, route of administration, dosage, source of knowledge, frequency of use, last time of use and farmers satisfaction) were collected. To compare our data with literature, one German book of veterinary pharmacology published in 1900, one typescript of Swiss lectures in veterinary pharmacology from 1944, four books of veterinary herbal medicine published between 1984 and 2016, and one recent publication comparing current Swiss (human) ethnomedicinal plant knowledge with modern and past literature were analyzed.

RESULTS

Information on a total of 315 homemade remedies containing one single plant species (homemade single species herbal remedy reports, HSHR) was collected from participating farmers. These HSHR were prepared from 83 plant species belonging to 46 botanical families. Plants of the families Asteraceae, Lamiaceae and Rosaceae were most frequently used. Matricaria recutita L., Calendula officinalis L., Quercus robur L., Thymus vulgaris L. and Symphytum officinale L. were the most frequently documented species. A total of 404 use reports (UR) were gathered for the 315 HSHR. The largest number of UR was for treatments of gastrointestinal disorders and metabolic dysfunctions, followed by skin alterations and sores. For more than half of the UR the source of knowledge was family, ancestors and friends, and for approximately one quarter the information was from courses and other educational events. For nearly 90% of the UR farmers mentioned at least one use during the last 10 years, and in more than 50% of the UR the last use was within the past year. Compared with recent and past literature and depending on different definitions of the term "traditional" as used for human medicine, between 43% and 84% of all 83 and between 57% and 100% of the most often mentioned 21 plant species show a "traditional" European veterinary use.

CONCLUSION

For the treatment of their animals farmers in the pre-alpine and alpine regions of the Swiss cantons of Bern and Lucerne mostly used plants which have a track record as medicinal herbs in Europe over several centuries. Almost half of the plant species had specific veterinary uses for about 120 years and even more for at least 30 years. The majority of the plant species thus fulfill the criteria of "traditional" according to several definitions and even more up to a certain degree the criteria of "traditional use" as defined in European regulations for human medicinal products. Ethnoveterinary research combined with data from historical sources may serve as a sound foundation for the development and definition of a Traditional European Veterinary Herbal Medicine maybe even with regard to the recent discussion about a simplified registration for Traditional Herbal Veterinary Medicinal Products.

[Arzneipflanzen im Berner Pferdestall: Erfahrungswissen von Pferdehaltern]

Hintergrund: Während über den traditionellen Einsatz von Arzneipflanzen durch Landwirtinnen und Landwirte beim Nutztier sowohl in Südeuropa als auch in der Schweiz zunehmend wissenschaftliche Veröffentlichungen vorliegen, fehlen gezielte Studien mit Pferdebesitzern weitestgehend. Mit der vorliegenden Studie sollte dieses Wissen exemplarisch für den Schweizer Kanton Bern erfasst werden. Probanden und Methoden: Methodisch an vorhergehende Studien in der Schweiz angelehnt, wurden von 2011-2012 7 Pferdehalter im Alter von 24-65 Jahren anhand eines semistrukturierten Fragebogens zum Einsatz von Arzneipflanzen bei ihren Pferden interviewt. Neben Informationen zu Pflanzenarten und Pflanzenteilen wurden die Zubereitung und Anwendung (inklusive Dosierung) der Rezepturen detailliert dokumentiert. Ergebnisse: Insgesamt wurden 21 Rezepturen von den Berner Pferdehaltern genannt, von denen 4 Mischungen aus 2-5 verschiedenen Pflanzenarten waren. In den Rezepturen wurden 27 Pflanzenarten aus 22 Pflanzenfamilien verwendet. Für mehr als 50% der Rezepte wurden die Arzneipflanzen in der Apotheke gekauft, jedoch lediglich für 1 (4%) beim Tierarzt; für ein weiteres Drittel der Rezepte wurden Pflanzen gesammelt. Für die 21 Rezepturen wurden 30 Anwendungen beschrieben, vor allem zur Behandlung der Haut, des Bewegungsapparats und der Atemwege. Am häufigsten wurden Anwendungen von Ingwer (Zingiber officinale) und Johanniskraut (Hypericum perforatum) genannt. Beide Pflanzen werden überwiegend zur innerlichen (Ingwer) bzw. äußerlichen Behandlung (Johanniskrautblütenöl) von Erkrankungen des Bewegungsapparats eingesetzt. Schlussfolgerungen: Gemessen an der Zahl der interviewten Pferdehalter kommt im Kanton Bern traditionell ein breites Spektrum von Arzneipflanzen beim Pferd zum Einsatz. Auch wenn Tierärzte aktuell kaum als Bezugsquelle für Arzneipflanzen dienen, dürfte das Potenzial für die tierärztliche Phytotherapie in der Pferdemedizin groß sein.

Urtica dioica (Stinging Nettle): A Neglected Plant With Emerging Growth Promoter/Immunostimulant Properties for Farmed Fish

Urtica dioica (stinging nettle), is a perennial plant belonging to the family of Urticaceae, genus Urtica. Despite the use of nettle in folk veterinary medicine is well documented, U. dioica is today an underestimated and frequently neglected plant, considered by the contemporary agriculture as a weed to be eliminated. This mini review focus on very recent studies on dietary administration of U. dioica, both as a single herb or in combination with other herbs, to enhance growth and stimulate farmed fish immunity, thus enabling the fish to be more resistant against bacterial infections. Such an emerging feature, together with cost-effectiveness, adequate availability, and easy processing of nettle, could make this herb an excellent, inexpensive and widely used dietary supplement on intensive fish farms.

Traditional uses of medicinal plants used by Indigenous communities for veterinary practices at Bajaur Agency, Pakistan

BACKGROUND

The pastoral lifestyle of Indigenous communities of Bajaur Agency is bringing them close to natural remedies for treating their domestic animals. Several studies have been conducted across the globe describing the importance of traditional knowledge in veterinary care. Therefore, this study was planned with the aim to record knowledge on ethnoveterinary practices from the remote areas and share sit with other communities through published literature.

METHODS

Data was gathered from community members through semi-structured interviews and analyzed through informant consensus factor (Fic) to evaluate the consent of current ethnoveterinary practices among the local people.

RESULTS

In total, 73 medicinal plants were recorded under the ethnoveterinary practices. Most widely used medicinal plants with maximum use reports (URs) were Visnaga daucoides Gaertn., Foeniculum vulgare Mill., Solanum virginianum L., Withania somnifera (L.) Dunal, Glycyrrhiza glabra L., and Curcuma longa L. New medicinal values were found with confidential level of citations for species including Heracleum candicans and Glycerhiza glabra. Family Apiaceae was the utmost family with high number (7 species) of medicinal plants. Maximum number of medicinal plants (32) was used for gastric problems. High Fic was recorded for dermatological (0.97) followed by reproductive (0.93) and gastrointestinal disorders (0.92). The main route of remedies administration was oral.

CONCLUSIONS

Current study revealed that the study area has sufficient knowledge on ethnoveterinary medicinal plants. This knowledge is in the custody of nomadic grazers, herders, and aged community members. Plants with new medicinal uses need to be validated phytochemically and pharmacologically for the development of new alternative drugs for veterinary purposes.

Folk use of medicinal plants in Karst and Gorjanci, Slovenia

BACKGROUND

Information on the use of medicinal plants in Karst and Gorjanci is not available in the literature, but collection of plants is still an important and widespread practice in these regions. Karst and Gorjanci are two remote regions in Slovenia that are only 120 km apart but have different climates; one region is close to the Italian border, and the other is near the Croatian border. Our aim was to report and compare the use of medicinal plants in both regions.

METHODS

From October 2013 to September 2014, 25 informants each in Karst and Gorjanci were interviewed during field research. The age of the informants ranged from 33 to 89 years, with an average age of 61 years in Karst and 69 years in Gorjanci. The main question was "Which plants do or did you collect from nature and use?" Plants of medicinal, nutritive, veterinary or cosmetic use were considered.

RESULTS

A total of 78 and 82 taxa were reported in Karst and Gorjanci, respectively; 65 taxa were reported in both regions. Approximately 64% of the plants in each region were distinctive for only a few informants (fewer than 7). The remaining plants were considered important, and the majority were mutual to both regions. Few reported plants were typical for just one region. Differences in the use of some common medicinal plants were observed, e.g., Matricaria chamomilla was used mostly for the treatment of gastrointestinal disorders, respiratory infections and sore eyes in Gorjanci but as a calmative in Karst. Altogether, 15 different oral and 15 different topical medicinal preparations were reported. Folk knowledge was found to be influenced by the media, particularly popular books about medicinal plants that were published in the 20th century.

CONCLUSIONS

The present research documents the folk use of medicinal plants in Karst and Gorjanci, Slovenia. This rapidly changing practice needs to be documented before it disappears or changes.

Swiss ethnoveterinary knowledge on medicinal plants - a within-country comparison of Italian speaking regions with north-western German speaking regions

BACKGROUND

Ethnoveterinary knowledge in Europe may play an important role as a basis for sustainable treatment options for livestock. Aims of our study were (a) to compare the ethnoveterinary practices of two culturally and sociodemographically different regions of Switzerland, (b) to compare results with earlier ethnoveterinary studies conducted in Switzerland and in adjacent Italian regions and, (c) to evaluate possible reasons for regional differences in European ethnoveterinary medicine.

METHODS

25 interviews were conducted in 2014 in all Italian speaking regions (ItR) of Switzerland, and 31 interviews were held in five north-western German speaking Cantons (GeC). Semi-structured questionnaires were used to collect detailed information regarding plant species, mode of preparation, dosage, route of administration, category of use, origin of knowledge, frequency of use, and satisfaction with outcomes of the treatments.

RESULTS

A total of 162 homemade remedies in ItR and 219 in GeC were reported, out of which 125 and 145, respectively, were reported to contain only one plant species (homemade single species herbal remedy report, HSHR). 44 ItR and 43 GeC plant species were reported to treat livestock, of which only a half were used in both regions. For each HSHR, we classified the treatment intention of all use reports (UR), leading to a total of 205 and 219 UR in ItR and GeC respectively. While cattle were the most often treated livestock species in both study regions, in ItR 40% of UR were administered to small ruminants. Main indications in both regions were gastrointestinal diseases and skin afflictions, but in ItR a high number of URs were reported as antiparasitics. URs were mainly handed down from the past generation, but in GeC the source of knowledge for 20% of URs were from courses. Regarding the used plant species, ItR showed a higher concordance with Swiss than Italian studies, but with some differences to all regions. A total of 22 (14 ItR; 8 GeC) plant species in this study have not been reported before in ethnoveterinary studies of Swiss and Italian alpine regions.

CONCLUSIONS

ItR and GeC, show differences and similarities with respect to their own ethnoveterinary practices and earlier Swiss and Italian ethnoveterinary studies. Linguistic, geographical, as well as social and farm-structural conditions influence the regional ethnoveterinary knowledge. However, political borders seem to be more important than language or geographical barriers.

Local knowledge held by farmers in Eastern Tyrol (Austria) about the use of plants to maintain and improve animal health and welfare

BACKGROUND

The sustainable management of animal health and welfare is of increasing importance to consumers and a key topic in the organic farming movement. Few systematic studies have been undertaken investigating farmers' local knowledge related to this issue. Ethnoveterinary medicine (EVM) is a discipline focusing on local knowledge and folk methods in veterinary medicine, however most ethnoveterinarian studies primarily address the treatment of animal diseases. Very few studies have explored prophylactic methods.

METHODS

An ethnoveterinary research project in Eastern Tyrol (Austria) was conducted in 2004 and 2005 to gather information about local knowledge of animal husbandry from 144 informants, with the emphasis on plants that maintain livestock health and welfare.

RESULTS

Informants mentioned a total of 87 plants and 22 plant-based generic terms in the context of maintaining and improving livestock health and welfare. The most important preventive measures for maintaining and improving animal health and welfare were practices related to "fodder" and "feeding". In this category the plants mentioned could be grouped according to three different perceptions about their effect on animals: "Good or bad fodder", "Functional fodder" and "Fodder medicine". In addition to fodder, environmental management, the human-animal relationship, household remedies and cultural/religious activities were also mentioned. When asked about practices in the past that maintained animal health and well-being, interviewees mentioned, for example, the importance of the diversity of sources that used to be available to obtain feed and fodder.

CONCLUSIONS

The informants' approach that feeding is central to livestock welfare is in line with the standard scientific literature on animal health, including in organic farming. Various scientific studies into common fodder evaluate the nutritive and dietary value, efficiency and safety of fodder. Future studies also have to consider the evaluation of traditional, local fodder resources. In fact, the value of 'food as medicine' for humans in the context of local knowledge has been widely assessed, but the potential health benefits of fodder and nutraceuticals in local and traditional ethnoveterinary methods require further attention.

Medicinal plants--prophylactic and therapeutic options for gastrointestinal and respiratory diseases in calves and piglets? A systematic review

BACKGROUND

Gastrointestinal and respiratory diseases in calves and piglets lead to significant economic losses in livestock husbandry. A high morbidity has been reported for diarrhea (calves ≤ 35%; piglets ≤ 50%) and for respiratory diseases (calves ≤ 80%; piglets ≤ 40%). Despite a highly diverse etiology and pathophysiology of these diseases, treatment with antimicrobials is often the first-line therapy. Multi-antimicrobial resistance in pathogens results in international accordance to strengthen the research in novel treatment options. Medicinal plants bear a potential as alternative or additional treatment. Based on the versatile effects of their plant specific multi-component-compositions, medicinal plants can potentially act as 'multi-target drugs'. Regarding the plurality of medicinal plants, the aim of this systematic review was to identify potential medicinal plant species for prevention and treatment of gastrointestinal and respiratory diseases and for modulation of the immune system and inflammation in calves and piglets.

RESULTS

Based on nine initial sources including standard textbooks and European ethnoveterinary studies, a total of 223 medicinal plant species related to the treatment of gastrointestinal and respiratory diseases was identified. A defined search strategy was established using the PRISMA statement to evaluate 30 medicinal plant species starting from 20'000 peer-reviewed articles published in the last 20 years (1994-2014). This strategy led to 418 references (257 in vitro, 84 in vivo and 77 clinical trials, thereof 48 clinical trials in veterinary medicine) to evaluate effects of medicinal plants and their efficacy in detail. The findings indicate that the most promising candidates for gastrointestinal diseases are Allium sativum L., Mentha x piperita L. and Salvia officinalis L.; for diseases of the respiratory tract Echinacea purpurea (L.) MOENCH, Thymus vulgaris L. and Althea officinalis L. were found most promising, and Echinacea purpurea (L.) MOENCH, Camellia sinensis (L.) KUNTZE, Glycyrrhiza glabra L. and Origanum vulgare L. were identified as best candidates for modulation of the immune system and inflammation.

CONCLUSIONS

Several medicinal plants bear a potential for novel treatment strategies for young livestock. There is a need for further research focused on gastrointestinal and respiratory diseases in calves and piglets, and the findings of this review provide a basis on plant selection for future studies.

Indigenous Knowledge on Animal Health Care Practices in Kendrapara District of Odisha, India

The objective of this work was to register and document the traditional knowledge of plant resources used in ethnoveterinary practices in Kendrapara district of Odisha, India. Investigation was carried out in the interior of the district, to explore the therapeutic uses of plants by local inhabitants. Information was collected using structured questionnaires, complemented by unstructured interviews and informal conversations with traditional healers, elderly people and farmers. Samples of plants that were reported to have medicinal value were collected and identified by botanical classification. Fifty five plant species, distributed among 34 families, were indicated for 27 different medicinal uses. The family Solanaceae had the largest number of reported species followed by Mimosaceae, Fabaceae and Apocynaceae. Prominent diseases treated by plant remedies were wounds, diarrhea, constipation, snake bite, skin ailments and rheumatism. Leaves were more commonly utilized for the preparation of ethnoveterinary medicine than other plant parts. The knowledge of traditional healers, and other experienced elderly people should be tapped to gather information on these practices so that it gets documented for the benefit of future generations. The present study contributed to the construction of an inventory of ethnoveterinary plants, which might provides a better database for future scientific validation studies.
