(Traditionally) used in Herbal Medicine to help relieve coughs, mucous buildup (catarrh) and irritation of the throat due to cold. [Source note 3].
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 restlessness or nervousness, coughs, mucous buildup and irritation of the throat due to cold).
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., Linden is traditionally used in Herbal Medicine to help relieve restlessness and/or nervousness).
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.
