“The evidence proffered to support craniosacral therapy is primarily anecdotal in nature, often taking the form of customer testimonials or case studies put forward by craniosacral practitioners. The mechanism by which CST practitioners claim they can detect the rhythms of cerebrospinal fluid and by which they claim to influence the body into healing itself are biologically implausible. To date, no robust evidence has been produced that would validate these claimed mechanisms. Because of this and because there is no good evidence that CST is effective for any condition, it seems likely that any effect perceived by those visiting a CST practitioner is due to placebo.” The Nightingale Collaboration (2011)
