There is not enough direct seb derm evidence to give this root extract a clear general recommendation. The published cosmetic review supports its assessed uses, but a later summary table conflicts with that finding; the discrepancy needs separate assessment review.

Extraction methods affect the material, and root extract differs from whole-plant and sprout extracts. Experimental itch testing and contact-allergy reports do not establish an independent seb derm treatment effect or a Malassezia response. Consider the full formulation and known botanical allergies, and ask for advice about persistent irritation.
