PLANTS 2022; 11:plants11050633. [PMID: 35270103 PMCID: PMC8912796 DOI: 10.3390/plants11050633] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/12/2022] [Revised: 02/19/2022] [Accepted: 02/21/2022] [Indexed: 02/01/2023]
Abstract
Traditional medicine is typically the most accessible primary healthcare for a large proportion of the people in Nigeria. However, its potential remains under-explored, especially with regards to their documentation. This research investigated and documented the use of medicinal plants in the management of various health conditions/diseases among local populations in Lagos State. This study was conducted in five (5) locations of Lagos State i.e., Alimosho, Badagry, Eti-Osa, and Epe (including Ijebu and Imota). Ethnobotanical information from 100 participants was obtained using semi-structured questionnaires. Frequency of citation (FC), relative frequency of citation (RFC), fidelity level (FL), and informant consensus factor (ICF) were used to assess the importance of plants utilised for various health conditions/diseases. We identified 183 plants from 61 plant families with the highest number (24) of plants belonging to Fabaceae. Based on the high FC, the top-five popular plants used for managing health conditions/diseases in the study areas were Mangifera indica (95%), Waltheria indica (93%), Zingiber officinale (87%), Alchornea cordifolia (83%) and Ipomoea involucrata (81%). Furthermore, Rauvolfia vomitoria, Urena lobata and Waltheria indica were recognised as the most adaptable plants, as they were used to treat five different health conditions/diseases. The most commonly used life-forms were herbs (34%) and woody species (shrubs; 30%, and trees; 22%). The most regularly used plant parts were leaves. The calculated RFC values for all medicinal plant species ranged from 0.01 to 0.95, while FL values ranged from 7.14 to 100%. We found 14 health conditions/diseases, with ICF values ranging from 0.88 to 0.95. Insomnia, insanity, convulsion, nervousness, and muscle relaxants had the lowest (ICF = 0.88) agreement, while malaria/fevers, stomach, and respiratory-related diseases had the most (ICF = 0.95) agreement. The documented therapeutic uses of the plants provide basic data for further research aimed at pharmacological and conservation studies of the most important flora existing in the study areas.

A Review of Ethnoveterinary Knowledge, Biological Activities and Secondary Metabolites of Medicinal Woody Plants Used for Managing Animal Health in South Africa. Vet Sci 2021; 8:vetsci8100228. [PMID: 34679058 PMCID: PMC8537377 DOI: 10.3390/vetsci8100228] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2021] [Revised: 09/30/2021] [Accepted: 10/08/2021] [Indexed: 11/17/2022] Open
Abstract
Globally, the use of ethnoveterinary medicine as remedies for animal health among different ethnic groups justify the need for a systematic exploration to enhance their potential. In addition, the increasing popularity and utilisation of woody plants remain common in traditional medicine, which may be attributed to their inherent benefits. The current review was aimed at analysing ethnoveterinary surveys, biological activities, and secondary metabolites/phytochemical profiles of the woody plants of South Africa. Eligible literature (period: 2000 to 2020) were retrieved from different databases such as Google Scholar, PubMed, Sabinet, and Science Direct. Based on the inclusion and exclusion criteria, 20 ethnoveterinary surveys were eligible and were subjected to further analysis. We identified 104 woody plant species from 44 plant families that are used in the treatment of different diseases in animals, particularly cattle (70%) and goats (20%). The most mentioned (with six citations) woody plants were Terminalia sericea Burch. ex DC and Ziziphus mucronata Willd., which were followed by plants with five (Cussonia spicata Thunb., Pterocarpus angolensis DC and Vachellia karroo (Hayne) Banfi & Galasso) or four (Acokanthera oppositifolia (Lam.) Codd, Cassia abbreviata Oliv., and Strychnos henningsii Gilg) individual mentions. The most dominant families were Fabaceae (19%), Apocynaceae (5.8%), Rubiaceae (5.8%), Anacardiaceae (4.8%), Combretaceae (4.8%), Euphorbiaceae (4.8%), Malvaceae (4.8%), Rhamnaceae (4.8%), and Celastraceae (3.8%). Bark (33%), leaves (29%), and roots (19%) were the plant parts dominantly used to prepare remedies for ethnoveterinary medicine. An estimated 20% of woody plants have been screened for antimicrobial, anthelmintic, antioxidant, and cytotoxicity effects. Phytochemical profiles established a rich pool of valuable secondary metabolites (phenolic, flavonoids and condensed tannins) that may be responsible for the exerted biological activities. Overall, the significant portion of woody plants lacking empirical evidence on their biological effects indicates a major knowledge gap that requires more research efforts.

PLANTS (BASEL, SWITZERLAND) 2020; 9:E1486. [PMID: 33158124 PMCID: PMC7694233 DOI: 10.3390/plants9111486] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/25/2020] [Revised: 10/27/2020] [Accepted: 10/29/2020] [Indexed: 11/16/2022]
Abstract
Many African countries are endowed with rich biodiversity with enormous nutritional and economic prospects, but the majority of these resources are not fully harnessed. Exploring these neglected resources, for example, the Transvaal red milkwood tree [(Mimusops zeyheri) Sond. family: Sapotaceae] is of paramount importance for food and nutritional security as well as economic prosperity. This review provides a critical appraisal of the nutritional and health benefits as well as the economic potential of Mimusops zeyheri. The plant is known for its diverse uses among rural communities. In folk medicine, the decoction from the bark and leaves of Mimusops zeyheri are used for treating wounds and ulcers, while the root is used as an infusion taken to treat candidiasis and other health issues. The nutritional profile of the fruit tree is similar to popular exotic fruits and richer in vitamin C when compared to guava and orange. Mimusops zeyheri is a rich source of vitamins, protein, and fatty acids. Based on the rich chemical pool, especially in the fruit and seeds, it has the potential to provide an accessible, readily available, and affordable enriched functional food with valuable health benefits. However, the successful exploration of Mimusopszeyheri for food security and sustainability requires multidisciplinary research. This will help achieve the envisaged food-nutrition security and poverty alleviation potential of the plant, especially among local communities.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Dovyalis caffra (Hook.f. & Harv.) Sim (commonly called Kei-apple) is an indigenous fruit tree that has medicinal values for various ethnic groups in southern Africa. AIM OF THE REVIEW This review aims to provide a critical appraisal of the existing knowledge on the ethnobotanical value, biological activities and phytochemicals of Dovyalis caffra. In addition, the potential of producing a functional health product from Kei-apple due to its therapeutic effects and rich pool of phytochemicals was explored. METHODS A detailed literature search was conducted using various online search engines, such as Scopus, Google Scholar, Mendeley and Web of Science. Additional information was sourced from ethnobotanical literature focusing on southern African flora. RESULTS Dovyalis caffra has diverse uses in local and popular medicine, specifically for relieving pain and rheumatism in humans. Ethno-veterinary potential of Kei-apple has also been documented in East Africa. Non-medicinal uses of the tree include its role in biological hedging and as a traditional herb for African magical purpose. Regarding its biological activities, polar extracts from the seeds exhibited noteworthy antibacterial (minimum inhibitory concentration of 1 μg/ml against Staphylococcus aureus) activity. Quantitative analysis (e.g. GC-MS, HPLC) indicated the presence of a rich (>80) pool of chemicals, including sterols, phenolic acids and fatty acids from different parts of the plant while 11 compounds have been isolated from its leaves and twigs. CONCLUSIONS Dovyalis caffra has been tested for various biological activities and the extracts (seeds in particular) demonstrated promising antibacterial potential. A lack of alignment between the ethno-medicinal uses and existing biological screenings was observed, indicting the need for anti-inflammatory and anti-rheumatism potential of Dovyalis caffra to be explored. In vivo validation of antibacterial and anti-parasitic activities against clinical bacterial strains and parasites, respectively is required. Other areas that need investigation are safety evaluations and development of integrated cultivation approach in order to fully explore the plant's potential.
