The key respondents were mainly old men, male traditional healers, traditional birth attendants and young women and all in total about 160 traditional healers were interviewed. To document male related ailments men are particularly more knowledgeable and most men share their problems with men. In addition, the old men and healers are the ones in charge of administering these herbal remedies. Young women through the informal discussions, interviews and market surveys are particularly more dynamic in the use of herbs for themselves, husbands and children besides being the most active reproductive age group. The medical ethnobotanical data collected has been analysed, medicinal plants from the study areas have been listed and methods of administering the herbal drugs were also documented. In checking for the proper updated naming, spellings and authors of the medicinal plants, besides using voucher specimens in Makerere University Herbarium, several reference books were used1,3,9,15,16,20,22,27.
The study was conducted between April 2000 and March 2003 in western Uganda. To collect this data indirect asking of questions and investigations that do not refer or offend anyone were used since nobody especially men can say openly that they have this problem. These methods are explained in the textbook of ethnobotany and others have been used in the field for this kind of studies in Uganda and elsewhere in the world10,12,13,14,21. These methods included visiting the traditional healers to document the indigenous knowledge (IK), regarding medicinal plants used, gender and socio-cultural aspects and where the plants are harvested. Informal and formal conversations, discussions and interviews, market surveys and field visits were conducted.
