Insufficient evidence to conclude whether or not Transcendental Meditation decreases blood pressure

A systematic review of randomized clinical trials testing Transcendental Meditation (TM) for cumulative effects on blood pressure found that all five evaluable trials had important methodological weaknesses and were potentially biased by authors' affiliation with the TM organization. Only one trial established adequate baseline blood pressure, only one included follow-up, and only one tested TM in hypertensive individuals. Three trials reported statistically significant differences favoring TM, while two found no significant differences. The review concludes there is insufficient good-quality evidence to determine whether TM has a cumulative positive effect on blood pressure.
