Can acupuncture help treat bell's palsy?

Bells: Ordinarily accupuncture is not of benefit for bell's palsy.

Yes: Yes, there is an auricular acupuncture protocol that is for specific for bell's palsy. See "auricualotherapy manual: chinese and western systems of ear acupuncture" by terry oleson, phd.

Proven vs unproven: By definition, "alternative" is different than modern western medicine. Generally any drug, herb, treatment, or procedure that stands up to rigorous scientific scrutiny is included in modern medicine. The problem is that many alternative practices, herbs etc do not stand up to scientific scrutiny and cannot be shown to work. Nerve injuries can be temp. Or permanent. Don't get scammed.
