The study, which received the support of the Development and Co-operation Management of the Swiss Confederation in the frame of the Socio-Sanitary Support Program Mali-Switzerland, proceeded from February to March 2004. The goal was to evaluate the impact of a workshop of formation of the prescribers on the Improved Traditional Phytomedicines (ITP), carried out in October 2001, on the consumption of the ITP in the medical structures of the District of Kadiolo. The study required the data-gathering of consumption, starting from the cards of stock of the years 2001, 2002 and 2003 of the Distributor Warehouse of the Reference Health Center and of the Pharmacies of the Community Health Centers. To evaluate the appreciation of the ITP, the investigations were carried out near the prescribers and the users. The overall consumption of ITP in CSRéf and 16 CSCom of the District knew a progressive increase, while passing from 2 565 480 F CFA in 2001 to 4 307 760 F CFA in 2003. The consumption of ITP during the year 2003 was of 27.83 F CFA per capita. The ITP in general were well appreciated by the prescribers and the consumers. Various projections of the consumption data recorded in Kadiolo allowed considering the potential market of the ITP currently available in Mali with a value ranging between 414 and 560 millions of F CFA.
