Plasters work through the skin. Plaster application therapy is one of the commonly used external treatments in traditional Chinese medicine. It follows the principles of syndrome differentiation and treatment, efficacy, indications and meridian tropism, fully mobilizes the efficacy of drugs to coordinate with each other, forms a compound prescription of multiple drugs, and gives full play to the good functions of drugs.

Because the plaster is directly attached to the body surface, most of the drugs used to make the ointment have a strong smell, and then the fragrant meridian-dredging drugs can play the roles of regulating qi and blood, dredging meridians, dispelling cold and dampness, reducing swelling and relieving pain by penetrating the skin and introducing them into the meridians and viscera.

Modern pharmacological research shows that black plaster is superior to rubber plaster in absorption and curative effect. However, the production process of black plaster is complicated, there is no uniform standard, and the quality is difficult to control, which leads to uneven quality of black plaster.

Because the production of black plaster is time-consuming and laborious, Chinese medicine hospitals often apply Chinese medicine externally, that is, Chinese herbal medicine is crushed and mixed with honey, vaseline and other substrates to make ointment, and then fixed with cotton paper and bandage.

Changing medicine every 24 hours is costly. Black plaster can be used for 3- 15 days at a time, and can be applied again after being removed, without affecting the curative effect, so the cost is low.

Traditional Chinese medicine surgical plaster is a kind of compound medicine by using the principle of meridian tropism of traditional Chinese medicine and the synergistic effect of drugs to give full play to the good effects of drugs. Because the plaster is used for thin sticking on the muscle surface, the medicine with strong smell is taken out from the plaster, so that the medicine guides a group of medicines and stagnates until it reaches the disease site.

Therefore, it can penetrate into the skin to produce the effects of diminishing inflammation and relieving pain, promoting blood circulation and removing blood stasis, dredging channels and collaterals, inducing resuscitation and penetrating bones, and expelling wind and cold. The plaster attached to the body surface stimulates nerve endings, dilates blood vessels through reflection, promotes local blood circulation, improves the nutrition of surrounding tissues, and achieves the purposes of detumescence, anti-inflammation and analgesia.

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.

Precautions for use:

1. When muscle contusion or joint ligament strain is caused by careless exercise or labor, do not immediately apply Shangshi Zhitong Ointment and Musk Zhuifeng Ointment to the injured part. Because this plaster has the function of promoting blood circulation and removing blood stasis, it can't achieve the purpose of detumescence and pain relief even after injury.

2. If there is local injury, don't stick the plaster directly on the injured part to avoid purulent infection.

3. All plasters containing musk, frankincense, safflower, myrrh, peach kernel and other ingredients for promoting blood circulation and removing blood stasis should be banned by pregnant women.

4. If papules and blisters appear on the local skin after application, and the itching is severe, it means that you are allergic to this plaster, and you should stop applying it immediately and carry out antiallergic treatment.

5. Allergy cannot be posted. If after 10 minutes, you feel itchy, burning and stinging on the skin of the pasted part, you should remove it quickly. This shows that the patient is allergic to plaster.

People with allergies are usually not suitable for plastering, because their skin is prone to rash, which is not only bad for drug absorption, but also brings skin problems.

6, no more than 24 hours Because the plaster is applied to the muscle surface, the plaster is generally applied to the body surface to stimulate nerve endings, dilate blood vessels and promote local blood circulation through reflection.

Improve the nutrition of surrounding tissues, and achieve the purposes of detumescence, anti-inflammation and analgesia. Generally, a dose of plaster should not exceed 24 hours at the longest. After a long time, not only did the medicine fail, but it was also bad for the skin.
