Why does it feel particularly hot when sticking plaster?

Plaster must be unfamiliar to everyone, and many people should have used it. Plaster is a kind of external traditional Chinese medicine, which was called thin ointment in ancient times. It is a gelatinous substance boiled with vegetable oil or animal oil, which can be coated on one side of cloth, paper or skin for a long time. When you are sore or have blood stasis, you will choose to stick a plaster. For most people, sticking a plaster will be accompanied by some reactions. For example, fever is the most common one. Why does sticking a plaster cause fever? Does that mean it's working?

First, it is normal for plasters to be hot, because most plasters contain important ingredients for promoting blood circulation and removing blood stasis, which will increase local blood circulation, so they will feel hot. Generally, fever will begin to appear within 5-20 minutes after plastering. In this process, the wind, cold, dampness and blood stasis of the patient will be decomposed and released, and will disappear after 3-5 hours. The fever and burning sensation will not have any impact on the skin. But different patients have different constitutions, and it is not necessarily a fever. Besides having a fever, what's the reaction to sticking plaster?

Second, some people get blisters when sticking plaster. This is not an allergy, but it is normal, indicating that the body is wet and the toxin has been discharged when blisters appear. Blisters are colorless, indicating that there is cold and dampness in the body. Yellow blisters indicate stagnation in the body. If there is blood in the blister, it proves that the body is wet. However, it should be noted that when blisters appear, don't pick them with a needle casually, otherwise it will not only hurt but also leave scars.

3. Pain caused by sticking plaster If you feel pain after sticking plaster, don't worry. This shows that the original blood stasis in the affected area has been dredged, and it sometimes hurts more when sticking plaster. As long as you insist on sticking plaster, the symptoms will gradually disappear after the reaction period, and some patients will take effect immediately after sticking plaster. In fact, plaster is not a magic medicine. If you choose to stick a plaster for many years, you should choose the one that suits you according to different situations.
