When using foot patches, choose carefully:

1. 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.

2. On the other hand, improper health care 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.

If you want to maintain your health, you can use methods such as foot bath or massage. Beat the Chinese medicine into fine powder, dissolve it in warm water at 40°C, and soak your feet for 15 to 30 minutes. Different symptoms require different medications, which require the guidance of a professional doctor. Commonly used medications include mugwort leaves, ginger, etc., which can promote metabolism and blood circulation. Appropriate massage of the outside of the big toes of both feet, or kneading the Yongquan point, also has a good health care effect.

Extended information:

1. Among the main ingredients of the foot patch, mugwort, also known as moxa leaf, is warm in nature. Oral administration can warm the meridians and stop bleeding. Moxibustion can warm the meridians, dredge meridians and relieve pain. External use can cause dryness. It is a commonly used traditional Chinese medicine to relieve itching due to dampness. However, bamboo charcoal, bamboo vinegar, tourmaline and other ingredients are rarely used in traditional Chinese medicine. Even if the medicine is correct, the skin on the soles of the feet is thick and the medicine has poor penetration. It is difficult to say whether external use can achieve the expected detoxification effect stated in the advertisement.

2. The theory of traditional Chinese medicine believes that there are three yin meridians and three yang meridians in the feet. After the feet receive medicine, they are transmitted to the corresponding organs through the three yin and three yang.

When the foot patch is applied to the sole of the foot, the relevant reflex areas on the sole of the foot are stimulated, blood circulation is promoted, and sufficient power is provided to the transporter protein in the subcutaneous tissue. The drug is absorbed transdermally under the action of the transporter protein. As blood circulation enters the body, harmful substances will also be eliminated through the skin under the action of transport proteins; harmful free radicals in the body will also combine with ions in the foot patch and be eliminated from the body in the form of diffusion; the combination of the two forms, Toxins in the human body can be effectively eliminated from the body and promote human health.
