Methods are different
Body acupuncture, ear needles, electrical stimulation and taped seeds are different approaches. Findings should be interpreted in relation to the method actually studied.
Combinations, not individual promises
Many studies examine combinations of points. This does not immediately reveal the contribution of a single point. Participant groups and comparison treatments also differ.
Start with a clear question
Describe what you would like to explore. Ask about experience with the approach and the limits of the service. A clear explanation is more useful than a blanket promise of success.
