Comfrey has strong healing abilities, leading to the name 'boneset'. It will help heal bone fractures and injuries and is very useful for permaculture gardens as it draws minerals out of the soil and stores it in the roots and leaves. Comfrey serves as a compost accelerator by releasing a fine ingredient as a liquid manure (comfrey tea). It is often used medicinal, as a compost activator and as fertilizer. It stays evergreen in warmer climates, but have a dormant time in cooler climates.
