I read the ebay info on the german stuff....hard to say.Homeopathy is effective in many situations. I personally use a lot of homeopathic products. There's plenty of other less expensive options in natural food stores. If you have a good wholistic doctor in your area I would visit them as well. DO NOT buy into the "there is no cure" hypnosis they force on the public on TV etc. Don't let a little sore on your body determine your self-esteem and self-worth. Seek spiritual counsel as well. Keep smiling.
