Reviewing some of what the mysterious placebo effect has been most effective with, includes hypertension, stress, cardiac pain, headaches, adrenal gland secretion, diabetes, colitis, menstrual pain, the common cold, fever, asthma, and multiple sclerosis. In fact, 60 to 90 percent of most drugs and
therapies prescribed by physicians depend on the placebo effect. Not surprising, zazen may well prove helpful in producting the placebo effect.
It is not unusual after several weeks of doing daily zazen for a typical practitioner to notice a general clearing up of their former malaise. We need to keep in mind that meditation is Asia's preeminent mind recharging exercise which can, to some extent, reboot the body’s invisible homeostatic system.
I would hope that some Zen centers and researchers take up a study of zazen and its possible connection with the placebo response. I think zazen offers more than just helping us feel good for a while. In fact, its true benefit all along may have been to produce the placebo response as no other therapy can. On this train of thought, in the future we might see zazen and certain Tibetan Vajrayana practices be incorporated by medicine to bring about the maximum placebo response in which invisible mind exerts its power over the brain.
