Medical diagnosis and therapy constitute a network of inter-related processes. The conventional method of medical diagnosis and therapy of diseases involve the state space search of medical knowledge of diseases and patient history, which could be combinatorial explosive. This paper presents the report of the experimental study of an intelligent, interactive, user friendly knowledge based system, which does a stepwise analysis of the patient's complaints, filtering the cognitive and emotional elements to be able to make inferences. It applies both forward and backward chaining in making inferences concerning the management of the diseases. A case study of the system is carried out using some tropical diseases. It is believed that the system will serve as a good contribution towards the much desired tropical medical informatics.
