From Charles F. Barth:

Re: Study seeks to show how acupuncture really works (May 30): Maiken Nedergaard’s research on the mechanism by which acupuncture relieved pain was quite interesting. The results, however, raise questions as to locating the source of the pain. Masking pain is largely palliative and, idiopathic conditions aside, may mask a serious condition that may be life-threatening.
