Because when stimulating meridian points, the following changes will occur in the corresponding parts: microcirculation improvement, nervous system excitement, internal and external secretion tissue excitement.

It's easy to explain.

Sweating is the expression of sweat gland excitement;

Farting is the result of increased peristalsis of intestinal muscles;

Weight loss should be to enhance metabolism, short-term weight loss should be faster water loss, long-term weight loss should be the mobilization of adipose tissue;

The generation of special odor should be mainly due to the production of special metabolites in the body, which are secreted and volatilized by sweat glands.

But all of the above are due to the connection between phenomena and human activities, not to the theory of traditional Chinese and western medicine. In other words, it is not necessarily what will happen when the so-called meridians are opened. Maybe a just sweats and b farts. This will vary depending on the patient's physical condition, the skill level of the performer, the combination of acupoints used and the theory.

Individuals will also have what you say when they are strongly psychologically hinted, but that may give the liar an opportunity.

Some Chinese medicine experts are still good, and they can't be killed in one stroke. The "shit theory" upstairs is an extreme view, so we must look at the problem scientifically and dialectically.
