③ Materia Medica Justice: "Tongcao, its smell is sweet and light, but it is non-toxic in Li Dongyuan's Medication Method". In this case, the word "sweet" is not called "big sweet", but it is actually a light word, such as spring water and rice, which are all called "sweet". This thing is odorless and tasteless, so it can pass through the meridians, clear away heat and promote diuresis. Its nature is similar to that of Akebia manshuriensis, but it has no bitterness, so it can relieve the downward force slowly without severe disadvantages. Although it can promote diuresis, it is not harmful to yin, and it is suitable for those who are not very hot and humid. If the heat is very close, it will not be as effective as Akebia manshuriensis. Dongyuan is said to benefit the yin and treat five stranguria, except edema and swelling, but only mild symptoms can help the ears. "It is also said that purging the lung is beneficial to urination, and it works together with the lamp grass. The cover is white and the smell is light and clear, so it can also go up. It is also advisable to vent the heat of the lung and declare the upper orifices, so the lower orifices are self-interested.
