“…ICF was calculated according to the previously described method 11 and used to determine the similarity of the types of plants used by herbal practitioners in treating various categories of diseases. An ICF value close to 0 or 1 indicates that the choice of plant for a diseases category is random or that the majority of herbal practitioners agree on the use of plants for a particular disease, respectively.…”

Background The demand for traditional herbal medicine is increasing and about 85% of the world population use herbal medicines for the prevention and treatment of diseases. More than 62.5% of the forest areas in Ethiopia are found in the southwest region, which have been used as a source of traditional medicine to treat different human and livestock ailments. The aim of this study was the investigation of the ethnobotanical and physicochemical properties of commonly used medicinal plants in Jimma zone, southwest Ethiopia. Materials and Methods A cross-sectional study was conducted in the district of Jimma zone from June 1 to 30, 2017. The ethnobotanical data were collected from traditional healers through semi-structured questionnaires. Specimens collected from various habitats were taken into Jimma University, Herbarium laboratory, dried, and prepared using standard herbarium specimen techniques for identification. Physicochemical analysis was done for selected medicinal plants. Results A total of 72 medicinal plants categorized under 61 genera and 39 families were stated by the respondents for the treatment of different human and livestock ailments. Herbs constitute the largest category (28 species, 38.89%) followed by shrubs (21 species, 29.17%), trees (20 species, 27.78%) and climbers (3 species, 4.17%). Leaves (39.19%) were the most commonly used plant parts followed by roots (27%) and seeds (10.81%). Traditional healers reported processing remedies mainly through crushing (46.91%), powdering (18.52%), pounding (11.11%), and pressing (9.88%). The water-soluble extractive value of the selected medicinal plants were between 1.825 to 18.507%w/w and the alcohol-soluble extractive value were between 0.143 to 1.107%w/w. The moisture content (%LOD) of Barleria argentea Balf. f. was higher than the recommended standard which consisted of 21.063%w/w and followed by high %LOD of Crateva adansonii D.C. Prodr (8.143%w/w) and Euphorbia abbyssinica J.F. Gmel. (16.347%w/w). The highest total ash value was registered in Dioscorea quartiniana A.Rich. species which consisted of 18.563%w/w and followed by Crateva adansonii D.C. Prodr (16.033%w/w) and Barleria argentea Balf. f. (15.648%w/w). High acid-insoluble ash value (7.227%w/w) and water-soluble ash (6.731%w/w) was recorded in Euphorbia abbyssinica J.F. Gmel. Conclusion The study revealed that the water-soluble extractive value of the selected medicinal plants indicates the presence of water-soluble components such as sugar, acids, and inorganic compounds. In the future, these characters can be used to check the genuine nature of the crude drug; thus, it plays an important role in preventing the possible steps of adulteration.

“…Traditional plants are also widely used to treat diarrhea. The bark and fruit of A. muricata are widely used by West Africans to treat diarrhea, and their antidiarrhea effects have been reported [81,82]. The fruit of A. muricata showed antidiarrhea activity at a dose of 400 mg/kg body weight in mice with castor oil-induced diarrhea.…”

Soursop (Annona muricata Lin.) is a plant belonging to the Annonaceae family that has been widely used globally as a traditional medicine for many diseases. In this review, we discuss the traditional use, chemical content, and pharmacological activities of A.muricata. From 49 research articles that were obtained from 1981 to 2021, A.muricata’s activities were shown to include anticancer (25%), antiulcer (17%), antidiabetic (14%), antiprotozoal (10%), antidiarrhea (8%), antibacterial (8%), antiviral (8%), antihypertensive (6%), and wound healing (4%). Several biological activities and the general mechanisms underlying the effects of A.muricata have been tested both in vitro and in vivo. A.muricata contains chemicals such as acetogenins (annomuricins and annonacin), alkaloids (coreximine and reticuline), flavonoids (quercetin), and vitamins, which are predicted to be responsible for the biological activity of A.muricata.

“…The inherent benefits such as relative affordability and accessibility of traditional medicine to a significant portion of the global population, especially in developing countries, further highlight the renewed interest from different stakeholders [ 4 , 5 , 10 ]. An increasing number of ethnobotanical studies are being done among diverse tribes and ethnic groups around the world, based on the understanding and acknowledgement of the relevance of plants for therapeutic effects and associated cultural value [ 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 ].…”

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.
