Hi. About forty years ago I badly sprained my left knee when the heel of my shoe broke. Since that time it occasionally becomes extremely painful, with a large swelling on the inside of the knee (I mean the side towards the other leg). A few years ago, however, I read about using cabbage leaves to treat joint pain and so thought I would give it a go. Hey presto! It worked. This is the treatment: Take some large dark green cabbage leaves and cut out the hard stalks. Next, in their raw state, crush them using a rolling pin until the juice starts to run a little. Then wrap them around the knee--right around and overlapping--and then apply a crepe support bandage to hold them firmly in place. This is best done just before bedtime. Go to bed, get a good night's sleep with your cosy knee held firmly in place, and wake up smelling like a compost heap. Unwrap the bandage, discarding the leaves, and test the leg gently. It works for me and also for a student I once had on a dance/drama course. He was about 16 and practically crippled with the pain from a knee that the doctors could do nothing about. He tried this remedy--and yes, it worked for him too! Excellent website--thank you.
