Q. Are 'Stress relief' claims allowed in product marketing?
Function claims permitted on a finished product depend on the target market and regulatory pathway (cosmetic, quasi-drug, FFC, Tokuho, dietary supplement). The function tag here is an editorial summary of the ingredient's documented or traditional benefit, not an approved claim. Always verify claim wording against your target-market rules.
