FAQ for OEM buyers

Q. What is the regulatory status of Swertia Japonica Extract for hair-care claims in Japan?

Swertia Japonica Extract (Senburi) is one of the 厚生労働省 (Ministry of Health, Labour and Welfare)-approved active ingredients for quasi-drug (iyakubugaihin) hair tonics with claims like 'prevents thinning hair' and 'promotes hair growth'. For these claims the product must be registered as a quasi-drug, not a cosmetic.

Q. Can Senburi extract be used in a regular cosmetic (not a quasi-drug)?

Yes — Swertia Japonica Extract is INCI-listed and can appear in regular cosmetic scalp tonics, but only general cosmetic claims (e.g., 'conditions scalp', 'gives the hair a healthy appearance') are allowed in that case. Quasi-drug efficacy claims are off-limits without quasi-drug registration.

Q. What is the source/sustainability profile?

Swertia japonica is a wild-harvested or cultivated bitter herb native to Japan, Korea, and parts of China. Domestically-cultivated Japanese material is preferred for Made-in-Japan positioning but commands a premium; wild-harvested supply can be variable.
