Jiegu: Bitter taste. Yin within yang. Start with Shaoyang, Shaoyin, and Jueyin meridians. It is bitter because it can be released, so it is good at dispersing.

It is the agent of Bupleurum and Pinellia ternata, combined with Foot Shaoyin and Shaoyang, and the cardinal Qi is divided into medicines. Therefore, the main symptoms include coughing, upper gas, sore throat, sore throat, and lack of news. This means that the Shaoyin cannot be closed or opened.

If you ask Shegan to treat exogenous phlegm and asthma, and there is a watery chicken sound in the throat, Shegan decoction must be used to treat it. It is necessary to understand the use of Shegan. But why can clouds be used temporarily but not permanently? There may not necessarily be cases of asthma that do not damage the Qi. The lung Qi is damaged by evil spirits, and wind and phlegm rush up along with it. It shoots dry into the lungs and can disperse the knots in the Qi, so wind and phlegm disappear when it encounters them. But if there are knots, the knots will be dispersed, and if there are no knots, the Qi will be dispersed. If the lung Qi is damaged by wind and phlegm in front of it, and if it is damaged by the Shegan, it will inevitably turn into deficiency and asthma. People don't understand the reason and think that shooting it in the past can cure asthma. If they use it to treat it, won't it hurt the lung qi? This is why it is said that it can be used temporarily, but not for a long time. If it is attributed to other diseases, why not?
