| Abstract | The current therapeutic use of medicinal plants mostly relies on indigenous knowledge, a system of knowledge that has been orally transmitted successively from generations to generation. Indigenous knowledge is being lost at a rapid pace as it still relies on oral transmission and that traditions such as story-telling are disappearing, which makes their documentation particularly crucial. In a similar vein, elders, parents, traditional health practitioners and herbalists have long transmitted orally from generation to generations their expertise of locally using herbs to treat various ailments. This repository of information, developed over millennia, needs to be documented and stored to allow integration into the official health systems. On this background, there is an urgent need for researchers to conduct studies and document on plants uses in the management of diseases, including non-communicable diseases. In Zanzibar, people have a tradition of using medicinal plants for their primary healthcare needs. The study aimed to collect information on medicinal plants used in the management of diabetes, asthma, and hypertension in Zanzibar. An ethnobotanical survey was conducted using a purposive sampling method, 24 traditional healers across 12 shehias/villages in all districts of Unguja and Pemba were interviewed. The study identified 24 plant species used for asthma management, 15 for hypertension, and 20 for diabetes. These findings highlight the continued importance of medicinal plants in disease management in Zanzibar and provide a foundation for further pharmacological and phytochemical research. Thus, the data revealed that, in Zanzibar, people still depend on medicinal plants for management of different diseases. The basic information on the medicinal plants identified will serve as a platform for ethnobotanists and pharmacologists to conduct further research regarding the pharmacological and phytochemical screening of plant species. |
