Hi Doc, A few questions about comfrey root please:
1. Can one use comfrey leaves and roots interchangeably for open wounds in humans or are their properties not the same?
2. I find it almost impossible to clean off all the mud from the roots. Is there a danger of introducing tetanus bacilli into open human wounds, using comfrey roots?
3. Can one dry comfrey roots in the sun?
4. Must I peel comfrey roots (the brown outer layer) before grinding it and if the answer is yes must it be peeled before or after drying?
Many questions thank you!
