💊 Why Herbalists Call Comfrey “Knitbone”
Comfrey has long been used to speed up the healing of bruises, sprains, strains, joint inflammation, and broken bones. It contains:
- Allantoin – stimulates tissue regeneration
- Rosmarinic acid – reduces swelling and pain
⚠️ Important:
Comfrey contains pyrrolizidine alkaloids (PAs), which can harm the liver if absorbed in large amounts or taken internally. Never ingest comfrey and avoid using it on open wounds or broken skin.
