Shingles (herpes zoster) is a viral disease that causes a red rash on the face or one side of the body, accompanied by fluid-filled blisters, pain, burning and tingling. According to the U.S. Centers for Disease Control and Prevention, approximately 1 million Americans suffer from this condition every year. In a systematic review of studies, researchers evaluated 59 randomized controlled trials involving almost 4,000 shingles patients that had been treated with acupuncture. They concluded that acupuncture therapies were effective and safe for the treatment of this viral disease, reducing pain and skin lesions with few adverse effects.
