Thailand is a member state of the ASEAN Economic Community, and next year, it is expected that the ASEAN Harmonization of Traditional Medicines and Health Supplements will be signed by the economic minister of each ASEAN country.

These guidelines cover a wide range of medicines and supplements; however, it is not possible to cover all herbal products.
There are three types of health supplement claims: nutritional claims, functional claims, and disease risk reduction claims. Examples of the three types of claims include the following:
Nutritional claims: supplements nutrition, nourishes the body, supports healthy growth and development, etc.
Functional claims: maintains healthy joints, supports immunity, maintains liver function, etc.

Functional claims and disease risk reduction claims must be substantiated by efficacy studies and the relevant toxicity data. It is the responsibility of the health supplement company to provide the required evidence in order to comply with the criteria for making such claims.
