Gastrointestinal anthelmintic plants used on small ruminants in Benin: Traditional use and scientific results - Review. Vet Parasitol Reg Stud Reports 2024; 50:101015. [PMID: 38644039 DOI: 10.1016/j.vprsr.2024.101015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Revised: 02/02/2024] [Accepted: 03/11/2024] [Indexed: 04/23/2024]
Abstract
In Benin, livestock breeders frequently use medicinal plants to treat gastrointestinal diseases in small ruminants. The aim of this review is to list the plants traditionally used in this context and to present the scientific findings on the efficacy of these plants. An extensive search was carried out using PubMed, Scopus, ScienceDirect, Biomed Central and Google Scholar databases to collect data, with combinations of relevant french and english keywords such as "ethnobotanical survey", "anthelmintic properties", "medicinal plants", "gastrointestinal parasites", "digestive strongyles", "Haemonchus", "Trichostrongylus", "small ruminants", "sheep", "goats" and "Benin". A total of 45 published articles met the eligibility criteria. This review listed 123 plants used by breeders to treat gastrointestinal ailments in small ruminants. The most commonly used parts are leaves and barks, and the most common forms are decoction, maceration and powder. Scientific studies have demonstrated the anthelmintic properties of 18 plants, including Zanthoxylum zanthoxyloides, Newbouldia laevis, Mitragyna inermis and Combretum glutinosum. The powders or leaf extracts of these plants showed in vivo significant reductions of over 50% in egg excretion, larval establishment, viability and fertility of gastrointestinal strongyles in small ruminants. Extracts of these plants also revealed in vitro inhibitory activity of over 50% on egg hatching, larval migration and motility of gastrointestinal strongyles. This manuscript highlights the traditional use of anthelmintic plants in small ruminants in Benin and provides scientific results supporting the efficacy of these plants.

Abstract
Covering literature to December 2022This review provides a comprehensive account of all natural products (500 compounds, including 17 semi-synthetic derivatives) described in the primary literature up to December 2022, reported to be capable of inhibiting the egg hatching, motility, larval development and/or the survival of helminths (i.e., nematodes, flukes and tapeworms). These parasitic worms infect and compromise the health and welfare, productivity and lives of commercial livestock (i.e., sheep, cattle, horses, pigs, poultry and fish), companion animals (i.e., dogs and cats) and other high value, endangered and/or exotic animals. Attention is given to chemical structures, as well as source organisms and anthelmintic properties, including the nature of bioassay target species, in vivo animal hosts, and measures of potency.

Abstract
Medicinal plants play a crucial role in the primary health care of the population in developing countries such as Benin. The national universities of Benin conduct research on the pharmacological, toxicological, and phytochemical properties of these plants, but the resulting knowledge often does not lead to the development of phytomedicines for the improvement of public health. This study aims to assess the current status of research on medicinal plants in Benin. A literature review was conducted using various search engines, and the collected data was analyzed. The results indicate that research on the biological properties of medicinal plants is still in its early stages, with limited and inadequate methodological approaches. These limitations highlight the urgent need to enhance research practices and facilitate the development of effective and safe phytomedicines.

Ethnomedicinal Information on Plants Used for the Treatment of Bone Fractures, Wounds, and Sprains in the Northern Region of the Republic of Benin. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:8619330. [PMID: 36588593 PMCID: PMC9797300 DOI: 10.1155/2022/8619330] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/09/2022] [Revised: 12/06/2022] [Accepted: 12/08/2022] [Indexed: 12/24/2022]
Abstract
Medicinal plants are frequently used in African countries due to their importance in the treatment of various conditions. In the northern Republic of Benin, traditional healers are recognized as specialists in the treatment of fractures, wounds, and sprains. The present study was conducted to document the practices (diagnosis and materials) and traditional knowledge accumulated by healers in this region on their area of specialty. In addition, literature-based research was performed to support the usage of the most cited plants. Sixty traditional healers identified as "reference persons" from Atakora and Donga departments in the northern Republic of Benin, who specialized in the treatment of fractures, wounds, and sprains, were interviewed in their communities through a semi-structured questionnaire. Information about the practice, age of the healers, medicinal plants used in this treatment, methods of preparation, and administration were collected. Samples of the plant species were also collected, identified, and stored in the national herbarium at the University of Abomey-Calavi, the Republic of Benin. The study enabled the identification of thirty-four (34) species belonging to twenty-three (23) families. Ochna rhizomatosa and Ochna schweinfurthiana (21%) were the most quoted plants among the species, followed by Chasmanthera dependens (12.1%), Piliostigma thonningii (11.3%), and Combretum sericeum (8.1%). These plants were reported to strengthen bones, reduce inflammation, relieve pain, and promote healing in the northern part of the Republic of Benin. Besides their ability to treat fractures, wounds, and sprains, they are also used for multiple purposes in the West African subregions. According to the available literature, some of the plants will need to be investigated for their phytoconstituents and pharmacological activity to validate their ethnobotanical uses. These results confirm the need for documenting traditional knowledge since it represents an opportunity for exploring plant species with potentially good pharmacological effects, which have been barely investigated. Plants identified may constitute a significant source of bioactive compounds in the treatment of various ailments such as skin inflammation and musculoskeletal disorders. They can be further explored to justify their use in traditional Beninese medicine.

Bailly C. Naming of new natural products: Standard, pitfalls and tips-and-tricks. PHYTOCHEMISTRY 2022; 200:113250. [PMID: 35598790 DOI: 10.1016/j.phytochem.2022.113250] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/05/2022] [Revised: 05/13/2022] [Accepted: 05/14/2022] [Indexed: 06/15/2023]
Abstract
Naming a newly discovered natural product (NP) is a pleasant but difficult exercise. In most cases, the NP name will be given with reference to the species of origin, be it a plant, a marine organism, a mammalian or microbial species. For a long time, the use of biologically-based trivial names has been recommended to identify the parental linkage between the product and the originating genus or species. But the recommendation is not always followed and a multiplicity of trivial names have been attributed to NP, based on locations (country, region, city), foods, music, animals, forenames, etc. Tips-and-tricks associated with the naming of NP are underlined here. Usually, NP are differentiated across a homogeneous chemical series with a letter (from the Latin or Greek alphabet), followed or not with a number. In other cases, the change of a single letter distinguishes a series of NP. Common pitfalls associated with the naming of NP are enumerated, including the complexity of names, use of synonyms, duplicated names, confusing names and inappropriate terminology. The difficulties regularly encountered with the naming of NP are discussed. Four essential recommendations are recalled: (i) a thorough analysis of the existing products to avoid duplicated names and confusion, (ii) the use of a biologically-based trivial name to retrace the origin of the product, (iii) the strict adherence to the codes of chemical nomenclature, and (iv) the preference for simple names to facilitate transmission. Naming a new NP is a rewarding task, which shall be performed with all due skill, care and diligence.
