For multi-ingredient products:
To prevent the product from being represented as a “traditional medicine”, any indicated traditional use claim must refer to the specific active ingredient(s) and recognized system of medicine from which the claim originates when 1) both the traditional and modern claims are present or 2) when claims original from multiple systems of traditional medicine (e.g., Panax Ginseng is used in Traditional Chinese Medicine to reinforce qi, benefit the spleen and lung, relieve symptoms of thirst due to impairment of body fluids and internal heat ).
When ALL of the active ingredients (MIs) in the product are used within the SAME identified system of traditional medicine AND the product makes ONLY traditional claims, listing of MIs in the traditional claim(s) is not required.
