I've just completed my first course at the grownetwork academy, Making Herbal Medicine and feel excited about putting that to good use. Dr Patrick Jones (character that he is) spoke about comfrey and its healing, especially drawing abilities. I've had a troublesome knee for 3 months now. I've tried everything I know, physio, chiropractic, massage and exercise but still giving me strife. So I got to thinking how about a comfrey fomentation or even a poultice! So I sit here now writing this with a warm towel soaked in comfrey and valerian tea wrapped around my knee and I will report back and let you know how it goes. I intend to do it 3 x daily. If anyone has any advice, I would surely appreciate it.
