The above uses can be combined on the product label if from the same traditional or non-traditional system of medicine (e.g., Traditionally used in Herbal Medicine to help relieve digestive upset including lack of appetite, nausea, digestive spasms, indigestion, dyspepsia, and flatulent colic and as an expectorant and cough suppressant to help relieve bronchitis as well as coughs and colds).
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 traditional system of medicine from which the claim originates when 1) both traditional and modern claims are present or 2) when claims originate from multiple systems of traditional medicine (e.g., Ginger is traditionally used in Herbal Medicine as an expectorant and cough suppressant to help relieve bronchitis as well as coughs and cold).
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.
