Context: Haemorrhoids are one of the most common gastrointestinal disorders in humans. In Tanzania, particularly in the Tabora region, medicinal plants (MPs) are used by traditional healers (THs) to treat haemorrhoids, but no study has explicitly attempted to compile these treatments. Objective: This study documents MPs used by THs of the Tabora region in Tanzania to treat haemorrhoids. Materials and methods: A semi-structured questionnaire was used to gather ethnobotanical data from 44 THs on MPs used to treat haemorrhoids, parts used, preparation methods and administration routes. The collected ethnobotanical data were analysed by computing percentage frequencies and relative frequency citations. Results: Twenty-six MPs belonging to 19 families and 25 genera, used to manage haemorrhoids, were documented. Fabaceae was the dominant family (four species), whereas shrubs constituted a high proportion (38.46%) of the MPs, and the root was the most (30.3%) utilized plant part. Decoction (38.5%) and topical application (53.8%) were the most preferred preparation and administration techniques. Most MP materials (76.9%) were sourced from the wild. Aloe vera (L.) Burm.f. (Asphodelaceae) (68%), followed by Allium sativum L. (Alliaceae) (66%) and Psidium guajava L. (Myrtaceae) (66%) were the most utilized MPs. Among the recorded MPs, 12 are reported for the first time for the treatment of haemorrhoids. The recorded MPs are believed to possess anti-inflammatory properties that aid in managing inflammation associated with bowel diseases, including haemorrhoids. Conclusions: This study has documented valuable MPs used to manage haemorrhoids and provides a basis for further studies to discover efficient and affordable anti-haemorrhoid drugs.
