I am acquainted with Dr. Chambers at MDACC. Please note how careful he was in his quote about acupuncture's ability to improve salivary flow.

In the study, 19 patients suffering from xerostomia due to radiation therapy underwent twice-weekly acupuncture sessions for 4 weeks. The patients were then tested for saliva flow and completed questionnaires designed to gauge the effects of the acupuncture sessions on their quality of life. �Patients in the study had improvements in their physical well-being and in subjective symptoms,� said Mark S. Chambers, D.M.D., a professor in the Department of Head and Neck Surgery and a study author. �Although the patient population was small, the positive results are encouraging and warrant a larger trial to assess patients over a longer period of time.�

There were only 19 people in the study, which is microscopic in its scope and ability to draw conclusions from it. Also notice the careful use of the word "subjective" in his quote. And while he comments on measurement of salivary flow pre puncture, he does not mention a measurable improvement in actual flow post accupunture.

The problem with all the acupuncture studies so far in the US, is very few of them took the time to actually, in a scientific method, measure salivary production/output pre acupuncture and post. They relied on the patients "perception" that something was better. None of the positive studies ever claim to have restored salivary function, and the impact of placebo effect is heavy in most of them.
