About
A fermented vinegar from Acorus calamus root and brown rice, combining the aromatic spice's traditional wellness uses with the skin-conditioning benefits of rice fermentation.
Acorus calamus (sweet flag) is a wetland plant whose rhizome contains a complex essential oil fraction including beta-asarone as a major component. The fermented vinegar preparation significantly reduces the concentration of free asarone through biotransformation during fermentation. The resulting product retains antioxidant polyphenols and organic acids while the fermentation process attenuates the original plant's toxicity profile. Acorus calamus has a long history in Ayurvedic and traditional medicine for its aromatic and protective properties, though its use is regulated in some jurisdictions due to asarone content.
