The effect of acupuncture is the effect of acupuncture stimulation on the physiological and pathological processes of the body and the reaction changes caused by its action in the body. There is generally no specific performance of qi and blood after acupuncture, but there will be some benign reactions during acupuncture, such as slight pain sensation, soreness and swelling, numbness and ankylosis. If there is no sensation from acupuncture, it is important to determine whether the acupuncture points are accurately positioned. If the soreness, numbness, swelling and pain do not subside after 24 hours of acupuncture, the amount of acupuncture stimulation may be too much. It is recommended that local hot compresses, tui-na, and massage are needed to improve the above symptoms. In addition to the immediate sensation, some patients will also experience sweating of the hands and feet, body heat, and rosy qi after acupuncture, etc. The reaction after acupuncture varies individually depending on individual physique. The movement of qi and blood is one of the main physiological functions of meridians. In Chinese medicine, qi is a fundamental part of survival, and it comes from the innate essence and the acquired zong qi. Blood has an important nutritional role mainly for the five organs and six bowels, and when blood deficiency occurs, the function of the whole organ will decline, leading to the failure of the body. Through the stimulation of acupuncture points, acupuncture can have the effect of unblocking the meridians, harmonizing yin and yang, and helping to eliminate evil. The effect of acupuncture is generally not caused by the acupuncture stimulation itself, but by the stimulation of acupuncture to stimulate or induce the inherent regulatory system in the body, such as the nervous system, the motor system, etc., so that the inherent regulatory system to play a regulatory function, so that the meridians of the disease can be unblocked, so as to reduce the symptoms or treat the disease effect.
