What should I do if I feel itchy after applying the Sanfu plaster?

There are many traditional treatment methods in traditional Chinese medicine. Most of the time, they are ointments, which means that if you want to cure a disease, you can just stick it on a certain part of the body. For example, the Sanfu plaster, which is often used to regulate the body during the dog days of summer, has a very good effect on treating diseases such as weak cough, bronchial asthma, and recurrent upper respiratory tract infections. However, many friends said that their bodies felt itchy after applying the patch. Why is that?

Experts say that most people will feel local heat and itching after applying the Sanfu plaster, which is a normal reaction. This is mainly because Sanfutie uses pungent, warm and fragrant drugs, which help the drug penetrate into the skin. Therefore, it may also cause allergic reactions such as redness, itching and even blisters on our skin.

Some people will develop blisters on the affected area two hours after applying the mask. This often happens to people with delicate skin. It should be noted that some people are not only allergic to drugs, but even adhesive tape can cause certain irritation to their skin. Such friends are not suitable for Sanfutie.

If the skin at the applied area feels itchy, burning or painful, remove the ointment in time and wash it gently with clean water. Scratching is strictly prohibited. It will usually heal on its own. If bubbling occurs, it is generally sterile and there is no need to worry.

If the blister is small, you don't need to pay attention to it, it will absorb by itself; if the blister is large, it may be very uncomfortable and itchy. You can first prick the blister with a sterilized needle, then use cotton wool to absorb the water that flows out, then disinfect it with iodine, and then apply some gentian violet, and then dry it. Remember not to tear off the epidermis.

After applying the Sanfu plaster, blisters will usually form scabs and fall off after a week. It has been observed that people who blister have better therapeutic effects because such people have better drug penetration and absorption. There is a kind of moxibustion method in ancient Chinese medicine called scar moxibustion, which requires blistering at the moxibustion site to achieve the best therapeutic effect.

Stop using Sanfutie immediately! You can apply calamine lotion externally, which has the effect of relieving itching and drying. If there is a lot of exudation and water flow, you can use boric acid cold compress. The concentration should not be too high, no more than 3%. For oral medication, you can choose Claritin syrup or Zyrtec syrup. Choose the dosage according to your weight according to the instructions! It is recommended to go to a regular hospital dermatology department for treatment. It will be safer to take the medicine under the guidance of a doctor!
