Electro acupuncture is a form of acupuncture where a small electric current is passed between pairs of acupuncture needles. According to some acupuncturists, this practice augments the use of regular acupuncture, can restore health and well-being, and is particularly good for treating pain. There is evidence for some efficacy (when used in addition to antiemetic) in treating moderate post-chemotherapy vomiting, but not for acute vomiting or delayed nausea severity.
