Top Quality Butterbur Extract is a standardized botanical derivative from Petasia macrophylla, primarily processed via solvent extraction to isolate active sesquiterpenes. The key marker compounds are petasins and depetasins. While specific molecular formulas vary by constituent, the extract is characterized by its high purity and low pyrrolizidine alkaloid (PA) content.
Strictly limit dosage due to potential hepatotoxicity from residual PAs; avoid use during pregnancy or lactation. Store in cool, dry conditions below 25°C to maintain stability of thermolabile petasins.
