These preparations have been made continuously for 2,600 years and remain shelf-stable at room temperature for decades. Western alcohol tinctures use pre-distilled ethanol at 25–80% concentration acting purely as a solvent, without chemically transforming the extracted compounds. In arisha fermentation, alcohol is generated in situ from jaggery sugars by living yeasts rather than added as a pre-made solvent. Shelf stability of the finished arisha results from three combined antimicrobial factors: alcohol content, acidic pH, and herbal polyphenols. Fermentation enzymatically modifies plant compounds into metabolites that are more bioavailable and more potent than those extracted by standard alcohol tinctures.
