That "critical review" says: "The best current evidence suggests that it is effective as a symptomatic treatment of dental pain, fibromyalgia, nausea/vomiting, knee osteoarthritis, insomnia, epicondylitis, chronic back pain, idiopathic headache, resolution of breech presentation and as an aid during gastrointestinal endoscopy" and then goes on to say that it may all be placebo effect. So the "critical review" is clearly intent on being critical. I trust that most people will have the judgment to read this "critical review" for what it is.
