The main ingredients of Pientzehuang are cow yellow, musk, panax pseudoginseng and snake bile, and its function is to clear heat and detoxify, cool blood and remove blood stasis, relieve swelling and pain, and it can be used to treat bruises, carbuncles, boils and so on. Generally speaking, Pientzehuang is still relatively safe and there are not too many adverse reactions reported, and at the same time, there is no obvious so-called detoxification reaction. Usually, if the treatment is effective, it means that the local abscess or boil gradually subsides and gets better. If the inflammation is not relieved and the redness, swelling and heat pain is more obvious after local use for 3 days in a row, it should be considered that the medicine is not effective enough or ineffective, and should not be considered as the so-called detoxification reaction, and then it should go to hospital in time and add some antibacterial and other drugs for joint treatment.
