It is is very popular in USA and also Brazil. However, it is not regulated as a medical practice. In USA, some health plans consider acupuncture as a valid "wellness" treatment, instead of medical treatment. Some universities are including acupuncture classes for a degree in "Alternative Medicine" (which is about to change its name to "Integrative Medicine" as it combines both Eastern and Western knowledge).

Paige: I just did a websearch in a single directory for Denver, Colorado. There are about 60 acupuncture practitioners in the Denver, Colorado area alone. There are possibly several hundred, / asian Restaurants in the Denver area by my estimation. Also, there are probably several dozen martial arts schools, based upon, Kung Fu, Ju-Jitus, Judo, Aidio, Karate, and so forth, at the minimum. The impact of Asian culture upon American life generally, is very pronounced and profound. ---Warm regards, Bruce
