The objective of this article is to describe and compare the use of traditional/complementary medicine (T/CM) among psychotic (schizophrenia and schizophreniform disorder) and epileptic Malay patients in peninsular Malaysia. There were 60 patients in each group. T/CM consultation was uniformly spread across all levels of education and social status. We could not find a single over-riding factor that influenced the decision to seek T/CM treatment because the decision to seek such treatment was complex and the majority of decisions were made by others. Fifty-three patients (44.2%), consisting of 37 (61.7%) psychotic and 16 (26.7%) epileptic patients had consulted Malay traditional healers (bomoh) and/or homeopathic practitioners in addition to modern treatment; of these, only three had consulted bomoh and homeopathic practitioners at the same time. The use of T/CM was significantly higher in psychotic than in epileptic Malay patients.
