I am a homeopath with over 15 years' experience. One patient was told she would have to have knee surgery in the near future due to osteo-arthritis in the knee. This was several years ago now and no surgery. She has been taking Ruta 6c once a day. She enjoys walking with no knee problems. She also has regular constitutional treatment which keeps her immune system strong.
My mom, who is elderly, had bad osteoarthritis in one knee, with pain, swelling, and limited range of motion. It would be severe at times. She started taking homeopathic Hypericum 30c 2 pellets twice a day for something totally unrelated.
The same day she started it, she was surprised to find that the swelling and pain in her knee was very much reduced, and she now had full range of motion. That night, she told me she got into bed bending that knee for the first time in years!
At first we thought it was just the change in weather, but it continued getting better so that she no longer needs a cane. She stopped taking it after two weeks, and the pain started to creep back, so she has started it again, with improvement again.
It was startling how fast the improvement was. We consider it a miracle, since we weren't even treating arthritis. It's nice to have a positive side effect for a change.
