Comfrey Leaf

Comfrey leaf (Symphytum officinale) is a traditional healing herb long used for wound care, bone health, and joint pain relief. It’s so effective that people once called it “knitbone” because of its ability to speed up the healing of bones and tissues.

A perennial herb native to Europe and Asia, now found worldwide.
Large, hairy leaves and bell-shaped flowers (purple, blue, or white).
Traditionally used externally in poultices, salves, and compresses.
Contains powerful compounds that promote tissue regeneration.

Key Compounds

Allantoin → stimulates cell growth & tissue repair.
Rosmarinic acid & tannins → anti-inflammatory.
Mucilage → soothing and protective for skin.
Pyrrolizidine alkaloids (PAs) → can be toxic to the liver if taken internally (important safety note).
