This study was conducted to evaluate the knowledge and perception on the use of (T&CM) and reasons for usage among patients visiting one government hospital in Malaysia. Self-administered questionnaires were distributed to 384 participants. Result showed that the majority of the participants reported using T&CM as an additive to their conventional medicines. Even though, most participants understood of the possible interactions that might occur, when combining T&CM with conventional medicines they remain dedicated to their practice. More study on T&CM should be conducted to ensure the accurate and trusted scientific evidence provided especially in term of safety and efficacy.
