Like conventional medicine, it is possible to harm as well as heal with any therapy, especially if careful monitoring is not maintained, particularly of doses, for example. If any practice that is harmful to the body continues for long enough, no matter how well-intentioned that might be, then it is possible that it could be lethal. That said, few direct deaths are recorded from alternative medicine, and many people find it helps with their conventional treatment, even if it is merely for the placebo effect it causes.
