 【Predecessors release medicine】
 "Compendium of Materia Medica" says: "Alisma is particularly good at moving water. Zhang Zhongjing said that water retention causes thirst, irritability, difficulty in urination, or vomiting or diarrhea, and Wuling Powder is the main treatment. The prescription uses Alisma, so we know that it is good at moving water. "Ben Jing" also quoted Bian Que as saying that taking it too much will make the patient's eyes dry, which is really to move the water. Zhang Zhongjing used it in Bawei Pills, but it was just to guide cinnamon, aconite, etc. to the kidney meridian, and there was no other intention. All those who take Alisma Powder will urinate frequently; if they urinate frequently, how can the kidney qi be restored? Nowadays, most people dare not use it to stop spermatorrhea."
 "Yi Jing Su Hui Ji" says: "Zhang Zhongjing used Alisma in Bawei Wan, and Kou Zongshuang's "Ben Cao Yan Yi" said that it was just to guide cinnamon and aconite to the kidney meridian, and there was no other meaning. I think that Rehmannia, Cornus officinalis, white Poria, and Paeonia suffruticosa are all kidney meridian medicines, so they don't need to be guided by Alisma before they can arrive. Aconite is a medicine for the right kidney's life gate, and cinnamon can supplement the deficiency of the lower Jiao's fire, but it also doesn't need to be guided by Alisma before it can arrive. Only dried yam, although it is included alone The hand Taiyin meridian, however, can also strengthen the yin, and the hand Taiyin is the upper source of the foot Shaoyin. Since the source is nourishing, how can the flow be useless? Moreover, although Zexie is salty and can purge the kidney, it purges kidney evil, not the root of the kidney. Therefore, the use of Zexie in Wuling Powder is not to purge kidney evil? White Poria also purges kidney evil, which is to replenish the body. Therefore, the use of Zexie in Bawei Pills is not for other reasons, but to purge kidney evil, nourish the five internal organs, strengthen qi and strength, raise yin qi, and replenish deficiency.
 "Compendium of Materia Medica Mengquan" says: "Although taking too much of Zexie can make your eyes blurry, taking it too quickly can also improve your eyesight. What is the meaning? It can remove hidden water and remove residual dirt, so it can improve your eyesight; urinating too quickly can cause kidney deficiency, so it can make your eyes blurry. You must know these two things."
 "Compendium of Materia Medica": "Alismatis has a flat Qi, sweet and light taste, light can penetrate and drain, and both the Qi and Qi are light, so it can promote diuresis and drain. If there is dampness and heat in the spleen and stomach, the head will feel heavy and the eyes will be dizzy and tinnitus will be gone. Alismatis can penetrate and remove the dampness, and the heat will also go away. The earth Qi will be able to get the order, and the Qi will go up, and the weather will be bright and refreshing. Therefore, Alismatis can nourish the five internal organs, increase Qi and strength, treat dizziness, and improve intelligence. If taken for a long time, it will be too much, the clear Qi will not rise, and the true Yin will be depleted, so how can you not have dizziness? Zhongjing Dihuang Pills, use Poria 、Zexie is used to purge the evil spirits in the bladder, not to attract them. The ancients used tonics to purge the evil spirits. When the evil spirits were gone, the tonics were effective. This is a mysterious way. Later generations did not know this principle and focused on tonics. Therefore, long-term use will inevitably lead to the harm of partial advantage. ""Shennong's book lists Zexie as a top-grade product, and also says that long-term use will make the body light and the face radiant. Tao and Su both believed it, but I secretly doubt it. Zexie can move water and purge the kidneys, but long-term use is not good. How can it have such magical effects? This is obviously absurd."
 "Compendium of Materia Medica": "Fang Longtan said that Alisma has the function of strengthening the kidney and controlling water retention, but it is different from Polyporus. Polyporus is diuretic and can separate and discharge the evil between the surface and the space; Alisma is diuretic and can clear the dampness of the internal organs." "Alisma is the main diuretic. Everyone knows that it can be diuretic; Danxi also said that it can be diuretic for the bladder and pericardium. If there is fire in the bladder and pericardium, it will cause urinary retention and swelling. When the fire is discharged, the water will flow, and when the water flows, the fire will fall. The two meanings of water and fire can coexist without contradiction."
 "Ben Cao Tong Xuan": "Bie Lu" says it can stop nocturnal emission, but Kou said that it is not suitable for people with nocturnal emission. What is the difference? For those with nocturnal emission due to the disorder of the fire in the body, Ze Xie can clear it and the semen can be stored. For those with weak qi and slippery semen, Ze Xie can lower it and the semen can become slipperier."
 "Pharmaceutical Chemistry": "For all diarrhea diseases, the urine must be short and frequent. This (zexie) can clear and moisten the lung qi, regulate the water channels, and transport it to the bladder. It is mainly used to treat watery diarrhea and wet diarrhea, so that the stool is solid, and the spleen is naturally healthy. Because it can benefit the water channels and remove the evil water, the real water can be nourished, so the thirst can be stopped. It can also remove dampness and heat, relieve stranguria, and eliminate fullness and fullness. It can penetrate the three burners to stop the water. This is the best product for promoting water. If the urine is not smooth and the patient is thirsty, the heat is in the upper burner qi. It is appropriate to use zexie and poria to clear the lung qi and nourish the upper source of water. If the patient is not thirsty, the heat is in the lower burner blood. In this case, use rhizoma anemarrhenae and phellodendron to drain the bladder and nourish the lower source of water. It must be used separately."
 "Compendium of Materia Medica" states: "Alismatis is the best at draining the water channels, and is especially good at clearing urine. Although the "Benjing" says that it has a sweet and cold smell, and because it grows in marshes, it is called cold, but in fact it is light and tasteless, so how can it be sweet? The function of this medicine is that it can clear the channels because it is light. The "Benjing" says that it can treat wind-cold dampness and arthralgia, and it is also because its lightness can enter the meridians and its lightness can guide moisture. It is said that it can treat wind-cold, which is not its job. Its ability to cure milk difficulty should be used for those who have no milk after childbirth. It can clear the meridians and clear the channels, so it can be used. It can help to secrete milk. It is not a universal medicine for all diseases related to milk production. …It can also dissolve phlegm and resolve fluid. Phlegm and fluid are also caused by stagnant water and dampness. It is smooth and beneficial, so it can resolve phlegm. In short, medicines that can dissolve and dissolve fluid must not have the function of nourishing. The Classic of Materia Medica says that it can nourish the five internal organs and increase the strength of Qi, which is too much praise. Zhen Quan even said that it can cure kidney deficiency and cause spontaneous ejaculation of semen. Daming even said that it can nourish women's blood and make them fertile. Jie Gu also said that it can enter the kidney meridian, remove old water, and nourish new water. None of them are true in pharmacology.
