Plaster works through the skin, and plaster therapy is one of the commonly used external treatments in traditional Chinese medicine.

Adding the pungent and fragrant menstrual drugs, it can play a role in regulating qi and blood, dredging meridians, dispelling cold and dampness, reducing swelling and relieving pain by penetrating into the skin and spreading to the meridians and viscera. Modern pharmacological research shows that black plaster is superior to rubber plaster in absorption and curative effect.

At the same time, the drug penetrates into the subcutaneous tissue of the affected area through the skin, resulting in the relative advantage of drug concentration in the local area, thus playing a powerful pharmacological role. In addition, because there are some highly irritating drugs in the plaster, strong stimulation can regulate the body function, promote the formation of antibodies, and improve human immunity through nerve reflex. After the drug permeates the skin and mucosa, it enters the systemic circulation through blood vessels or lymphatic vessels, which can also produce systemic drug effects. ?
