“…More than half (60.7%) of the species used to treat and manage circumcision wounds are traded as herbal medicines in local, regional and international 2). Selling of the bark, bulbs, fruits, leaves, rhizomes, roots, seed oil, stems and whole plant parts of these species in Algeria, Botswana, Burundi, Eswatini, Ethiopia, Lesotho, Malawi, Mozambique, Nigeria, Rwanda, South Africa, South Sudan, Tanzania, Zambia and Zimbabwe generates economic opportunities for vulnerable groups living in periurban, rural and marginalized areas (38,(96)(97)(98)(107)(108)(109)(110). It was observed that there is an increased trade both at domestic and international levels for medicinal plants with known phytopharmaceutical, nutraceutical and cosmeceutical properties (111).…”

Medicinal plants used to treat and manage circumcision wounds have remained an integral part of traditional practice in Eastern and Southern Africa. This study reviews the traditional usage of medicinal plants to treat and manage circumcision wounds in Eastern and Southern Africa. Drawing on data from Kenya, Namibia, South Africa and Tanzania, information was collected from different sources including books, theses and electronic scientific search engines such as Scopus, Science Direct, PubMed, SciFinder and Google Scholar. A literature search was also undertaken focusing on medicinal plants used against circumcision wounds that demonstrated antibacterial and anti-inflammatory activities in in vitro studies. Twenty-eight medicinal plants from 15 families are recorded as traditional therapies for circumcision wounds following an extensive literature search. These species used to treat and manage circumcision wounds, and as dressing after circumcision to prevent serious inflammation are mainly (64.3%) members of Amaryllidaceae, Asparagaceae, Asteraceae, Euphorbiaceae and Fabaceae families. Three quarters (75.0%) of these species including Acalypha ornata, Achyranthes aspera, Asparagus africanus, Boophone disticha, Brunsvigia grandiflora, Burkea africana, Colophospermum mopane, Datura stramonium, Dichrostachys cinerea, Helichrysum appendiculatum, H. foetidum, H. longifolium, H. nudifolium, H. pedunculatum, Lippia javanica, Maesa lanceolata, Ptaeroxylon obliquum, Ricinus communis, Searsia natalensis, Triumfetta rhomboidea and Vachellia nilotica have shown antibacterial and anti-inflammatory effects in a set of in vitro models. Further studies are needed such as isolation of phytochemical compounds, in vivo activities, clinical and toxicological studies.

“…The leaves of M. zanzibarica are browsed by game and livestock (Komwihangilo et al, 1995;Mtengeti and Mhelela, 2006). The leaves of M. zanzibarica are sold as traditional medicines in informal herbal medicine markets in Tanzania (Hilonga et al, 2019). Therefore, this extensive review was undertaken to evaluate the medicinal uses, phytochemistry and biological activities of M. zanzibarica.…”

Markhamia zanzibarica (Bojer ex DC.) K. Schum.has been used in herbal medicine in tropical Africa since ancient times. Markhamia zanzibarica is indigenous to central, eastern and southern Africa. This extensive literature review synthesizes the information currently available on the medicinal uses, phytochemistry and biological activities of M. zanzibarica. The University library and electronic search engines Google Scholar, Scopus, Web of Science, ScienceDirect and PubMed were searched for pertinent information on the medicinal uses, phytochemistry and biological activities of M. zanzibarica. Traditionally, the species has been used as anthelmintic, and traditional medicine for backache, female reproductive problems, sexually transmitted infections, respiratory infections and gastro-intestinal problems. In vitro studies have confirmed the biological activities of M. zanzibarica which include antibacterial, antimycobacterial, antioxidant and cytotoxicity. Various phytochemicals such as alkaloids, anthraquinones, fatty acids, flavonoids, glycosides, phenolics, saponins, sterols, tannins and triterpenes have been isolated from M. zanzibarica. Documentation of the medicinal uses, phytochemistry and pharmacological properties of M. zanzibarica is essential as this information provides baseline data required for future research and development of health-promoting and pharmaceutical products. However, further pharmacological studies including phytochemical, toxicological, in vitro and in vivo experiments are needed to provide evidence for the clinical effectiveness of remedies prepared from the species.

“…Clausena anisata (Willd) Hook (Rutaceae) stem bark, roots, and leaves are used in Tanzania against oral candidiasis and fungal infections of the skin (Hamza et al, 2006). The leaves of the two plants were used in formulating medicinal concoctions and their minimal effect in survival of the plant after harvest (Hamza et al, 2006;Hilonga et al, 2018). This study investigated seasonal effect on the chemical composition and antifungal activity of leaves of C. anisata (Rutaceae) and T. holstii from the Mafinga district of Iringa regions in Tanzania.…”

Curative dependence on season of harvest for medicinal plants is an alleged claim by traditional health practitioners. This study aimed to verify these claims by investigating antifungal activity and chemical profiles of two traditionally used medicinal plant species: Turraea holstii and Clausena anisata harvested in the rainy and dry seasons, with a view of establishing appropriate the season for optimal activity. The antifungal activities were determined by Broth micro-dilution method, while chemical profiling of the extracts from the plant materials was done by gas chromatography (GC). Results indicated that extracts of plant materials harvested in dry season showed enhanced antifungal activity as compared to extracts of plant materials harvested in the rainy season, highest potency being 0.39 mg/mL, observed on dichloromethane fractions of both T. holstii and C. anisata. The GC chromatograms showed a general increase in the number and amount of chemical species for extracts of plant materials harvested in dry season as compared to extracts of plant materials harvested in the rainy season. Thus, it is concluded that because the dry season produces the best curative activity, harvesting should focus on this season.
