Advice to consumers

Due to the fact that the use of traditional medicine has gained a place in the hearts of consumers in Malaysia, the issue of safety, efficacy and quality of medicines should be emphasized. Consumers are advised to choose a traditional product that has been registered with the Ministry of Health with a valid registration number. Moreover, if there is any doubts, do consult a pharmacist or doctor if you want to take traditional medicine with modern medicine.

Patients suffering from chronic diseases are recommended to refer to hospitals and health professional because traditional medicines are just an alternative treatment. Consumers are also advised to consult a doctor immediately if experience severe allergic or persistent side effects when taking these traditional products.

In addition, consumers should be vigilant on the preparation of traditional medicines because the preparation process and storage may affect the safety, effectiveness and quality of the product. Excessive dose can also pose a danger to health. Therefore, consumers should seek advice from experts and accredited bodies such as National Pharmaceutical Regulatory Agency (NPRA) [formerly known as National Pharmaceutical Control Bureau (NPCB)] if you want to get the validity of information related traditional products.
