Some people still think it is snake oil, an MD friend of mine went to China and after observing said it did not work. However it does work. I have used in, in desperation, to quit smoking and for muscle spasm and it worked both times. Smoking was the more difficult. My friends, many of whom are MDs, insisted that it was a placebo effect. In answer, my daughter has two horses and the vet frequently uses acupuncture for their muscle spasm. I don't believe that horses have placebo effects. When acupuncture was first introduced in the states (US) a group of doctors I know went to China to learn, not visit and came back convinced that it has it uses. Don't laugh at it. It won't cure PD, but I wonder if it would help the associated muscle spasms. If any of you have tried it, please let me know. I do not have PD, but I do have a very nice, but stubborn , husband who does. bye Nita
