Experts point out that mugwort foot patches have no effect.

Chang Zhangfu, a professor at the Department of Clinical Chinese Medicine at Beijing University of Chinese Medicine, told the "Life Times" reporter that regardless of whether the powder in the mugwort foot patch turns black due to a chemical reaction, simply because the powder becomes moist, Darkening does not mean that dampness or toxins have been removed.

Dampness evil involves many aspects. Common manifestations include greasy tongue coating, stomach discomfort, loose stools, soreness of limbs or edema, etc. Whether to eliminate it depends on clinical symptoms. As for the word "detoxification", Chinese medicine rarely uses it, and generally uses "detoxification".

Chang Zhangfu analyzed that among the main ingredients of the foot patch, mugwort, also known as mugwort leaf, is warm in nature. When taken internally, it can warm the meridians and stop bleeding. Moxibustion can warm the meridians, dredge meridians and relieve pain. When used externally, it can dry out dampness and relieve itching. It is a commonly used traditional Chinese medicine. ; Bamboo charcoal, bamboo vinegar, tourmaline and other ingredients are rarely used in traditional Chinese medicine. Even if the drugs are matched, the skin on the soles of the feet is thicker and the drug penetration is very poor. It is difficult to say whether external use can achieve the expected therapeutic effect stated in the advertisement.

Chang Zhangfu suggested that health preservation should not be too blind, but should learn to identify and choose carefully. On the one hand, the human body metabolizes waste in the body through the liver, kidneys and digestive system, and excretes waste through defecation, perspiration, breathing and other channels. Normal people can complete these steps without additional "detoxification." To remove dampness and detoxify, you need to prescribe the right medicine under the guidance of a professional doctor after different symptoms appear.

On the other hand, improper health maintenance methods will harm the body. For example, foot patches use some warming drugs, which may aggravate the condition of people with yin deficiency who are prone to internal heat. In addition, a 2012 study on a certain foot patch in India showed that 25 out of 100 people who used the foot patch developed allergies, accompanied by symptoms such as skin redness, swelling, itching, and even coughing and fever.
