Traditional medicinal plants used by Kunama ethnic group in Northern Ethiopia

Utilization of medicinal plants is almost as old as the history of mankind. Semi-structured interview, guided field walk, group discussion and market survey were used to collect ethnobotanical data in Tahitay Adiyabo and Kafta Humera districts in northern Ethiopia. A total of 47 informants (30 males and 17 females) were selected purposefully from three sub-districts: Lemlem (n = 27), Adi-Goshu (n = 10) and Hilet-Coca (n = 10). A total of 115 species of medicinal plants were collected and identified for treating 59 humans and livestock ailments. The most commonly used plant parts for herbal preparations were roots (35.5%) and leaves (21.74%) and were administered through oral, dermal, ocular, nasal and vaginal routes in decreasing order. Oral application (58 preparations, 50.43%) was the highest and most commonly used route of application followed by dermal application (35 preparations, 30.43%). Kunama tribes are rich in medicinal plant species and the associated indigenous knowledge. Future studies should focus on phytochemical extraction of herbal drugs for their efficacy and possible toxicity.   Key words: Kunama, KaftaHumera, Tahitay Adiyabo, ethnobotany, traditional medicine.
