Interactions

incompatible with: avoid prolonged use with products intended for broken or irritated skin, avoid combining with other potentially sensitizing botanical extracts in highly reactive formulas, avoid in pregnancy- or lactation-focused products unless supplier safety data specifically supports use

Risks & Warnings

Main safety concern is the possible presence of pyrrolizidine alkaloids (PAs), which are toxic compounds associated with hepatotoxicity and genotoxicity concerns. Risk is greater with internal use, prolonged exposure, or use on broken/compromised skin. Comfrey-containing products are generally avoided in pregnancy and lactation due to limited safety data and alkaloid concerns.
