The main function of Mafeisan is to relieve pain.
Mafeisan is the earliest anesthetic in the world, which has a long history and is very troublesome to prepare. The effective combination of Buxus macrophylla, Li Ronghua, Angelica sinensis, Acorus calamus and other traditional Chinese medicines can play a certain role in local anesthesia.

Origin:
Mafeisan is the earliest anesthetic invented and used in China in the world, which was created by Hua Tuo, an outstanding physician in the late Eastern Han Dynasty.
There are related accounts in the Romance of the Three Kingdoms. It is said that Hua Tuo's son cooked Datura fruit and died unfortunately. Hua tuo is very sad. On the basis of Datura stramonium, he added several other Chinese herbal medicines and developed the earliest anesthetic in the world. In memory of his son, he named this medicine Leprosy Powder.
Guan Yu, the general of Shu State, was shot by a poisonous arrow in his right arm when he was fighting against Wei Jun of Coss, and his arm was red and swollen, which was very dangerous. The Shu army invited Hua Tuo, a contemporary famous doctor, to Xiangyang to treat Guan Yu. After seeing the wound, Hua Tuo decided to have an operation and suggested taking Mafeisan anesthesia. Guan Yu refused to use it, so Hua tuo tied the sick arm to an iron ring on the wooden frame and locally applied powerful anesthetic.
He took out a sharp knife, scraped off carrion and broken periosteum, put medicine on it, and sewed up the wound with silk thread, so that Guan Yu saved his life and arm. Later, Hua Tuo suggested that Cao Cao open the skull, and he also used hemp boiling powder. Cao Cao did not believe Hua Tuo and executed him.
