Most of us are familiar with signs like blackness under the eyes, oily skin, pimples, lines on the forehead, and bulging eyes. Each of these indicates a specific health problem. There are a lot of other signs that signify a specific health problem. Face reading cannot be used to determine the root cause, and since acupressurists are interested in the root cause, they have to do pulse reading to get to the main problem.

It is impossible to cure a patient suffering from say a problem like high cholesterol in a week. It might take at least one or two months or even more for the patient to get cured.

Z points activate the adrenal gland so that the gland itself produces cortisone for the body.
