Learning sutra requires sharing experience. Therefore, I always advocate that we should contribute our experience without reservation, so that we can improve together. Today, I will also introduce some clinical application experience and some information I have collected, and the topic is the clinical application of Ephedra. There are a lot of clinical experts here, you all have unique experience in the application of ephedra, I am just throwing a brick to draw in the jade, I hope to draw your attention to the ephedra formula. About Ephedra Ephedra is a traditional Chinese medicine for sweating, asthma, water retention and swelling, as well as a stimulant. As you know, methamphetamine is mainly derived from ephedra, which is extracted from ephedra. There are 14 ephedra formulas in the Treatise on Typhoid and 13 in the Jin Kui, such as Ephedra Tang, Da Qing Long Tang, and Ephedra with seeds and fine spices Tang, all of which are important formulas in the Classic. Ephedra is a medicine that people are really afraid to use, especially in our area of Suzhou, Jiangsu Province, where it is used very carefully, not daring to use more. I remember when I was studying medicine, my teacher also repeatedly stressed that ephedra should not be used in excess, with five or eight points, with a penny. There are also people who are afraid to use ephedra, just use ephedra water to decoct and soak soybean yellow rolls to use instead of ephedra. Because there are indeed cases of ephedra after leading to deficiency. The Qing people Xu Zhongyuan “three different pen-talk” recorded such a thing: said a five-year-old child, the lung wind, at first three points of ephedra did not work, and then increase the amount to five points, five points and failed, to the third diagnosis he used seven points, well, this seven points of ephedra down, the child’s forehead sweat like a pearl, the pulse has been removed, the results quickly with ginseng, Wu Wei Zi, oyster, dragon bones to save off. Later a check of the original medicine, oh! The first two consultations with ephedra are false ephedra, the third time is the real ephedra, real ephedra seven points has been too heavy. This medical discourse suggests that true ephedra sweating is indeed very powerful. Qing dynasty Lu Dingpu wrote “Lenglu medical words” also said that there was a doctor, look at the Song dynasty Xu Shuwei’s “Typhoid Ninety”, very much like, as a secret book. He saw that Xu Shuwei was good at using ephedra soup, so he also learned to use it. He used Ephedra Tang for a woman who was suffering from fever and had no sweat, and the patient died of sweat. In the United States, ephedra is forbidden. Why? In the United States in the 1980s and 1990s, ephedra was widely used as a weight loss drug. They used ephedra to lose weight, but they did not follow the indications for the use of ephedra in Chinese medicine, and something went wrong. In 1994, a woman died in a tennis tournament in the United States, and it was later found to be related to the use of a weight loss drug containing ephedra. After the U.S. FDA notification, the use of ephedra was banned. Not only is it banned in the United States, but also in Australia and the United Kingdom, ephedra is banned. But many doctors get ephedra and use it, because ephedra is indeed a good medicine, and doctors who do not use ephedra are not good doctors. Ephedra is lovely, and Ephedra is also very attractive.
