Really Bad Dry Mouth
In this research they were looking at people that suffer from chronic xerostomia (dry mouth) from raditation therapy for cancer treatment. They compared acupuncture treatment , sham acupuncture and standard oral hygiene. It was fairly well designed research with a randomized, blinded, 3-arm, placebo-controlled trial conducted for 8 year. They found that the people who got the true acupuncture did better than both of the comparison groups!
