 【Predecessors release medicine】
 "Ben Cao Jing Shu": Cistanche deserticola, a key medicine for nourishing the kidney and replenishing essence and blood, has a slightly warm qi, and it is said that those who think it is hot are wrong. Sweet can remove heat and replenish the middle, sour can enter the liver, and salt can nourish the kidney. The kidney and liver are yin, and the yin qi grows, then the fatigue and heat of the five internal organs will retreat, and the cold and heat pain in the penis will heal itself. If the kidney and liver are sufficient, the essence and blood will flourish, and if the essence and blood are flourishing, there will be many children. Women's symptoms and masses are caused by blood. If the blood is flourishing, the symptoms and masses will disappear. If the bladder is weak, the evil will come, and if it is replenished, the evil will disperse and the waist pain will stop. Long-term use will make the body fat and healthy, and the body will be light. It is also the effect of nourishing the kidney and liver to replenish essence and blood. If it is said to cure dysentery, how can it be slippery to guide the stagnation? This is also a saying that it must not be possible.
 "Compendium of Materia Medica" says: Cistanche deserticola nourishes the gate of life, nourishes the kidney qi, and replenishes the essence and blood. For men with cold and weak Danyuan and long-term yang descent, and women with disordered Chong and Ren meridians and untreated yin qi, this is a mild tonic, warm but not hot, tonic but not harsh, warm but not dry, smooth but not leaky, so it is called calm.
 "Ben Jing Feng Yuan": Cistanche deserticola, according to Ben Jing, is used to treat fatigue and injury, which is caused by the inability of fire to generate earth, not the deficiency of the qi in the middle. It is used to treat women's diseases and masses, because salt can soften the hard masses and move the blood. Cistanche deserticola can also stop spermatorrhea and urination, and eliminate heat and pain in the penis, because it can guide the virtual fire downward. For the elderly with dryness and constipation, it is suitable to cook porridge and eat it.
 "Yuchu Yaojie": Cistanche, warms the waist and knees, strengthens bones and flesh, nourishes kidney and liver essence and blood, moistens the intestines and stomach, and resolves dryness. All feces are hard and small, shaped like sheep dung, this is because the soil is damp and the wood is depressed, and the lower orifices are blocked. The grain residue is in the stomach and cannot go down smoothly. It is transmitted sporadically, broken and unconnected. It has experienced the dryness of the Yangming large intestine and is refined into particles. It is difficult to pass. It is all because the wind and wood are withered and the drainage is not working. Taking Rehmannia and turtle glue will increase the soil and dampness, and the middle qi will be more defeated. Cistanche nourishes wood and clears wind, nourishes blood and moisturizes dryness, is good at lubricating the large intestine, and resolves feces. Its nature is unhurried, and it does not nourish dampness and ruin the spleen. It is not comparable to other moistening medicines. The prescription book says that it replenishes essence and marrow, brightens the complexion and prolongs life, and can cure men with impotence and women with impotence. This is not an exaggerated praise.
 "Ben Cao Qiu Zhen" says: Cistanche deserticola is said to be a strong supplement for essence and blood, and also to be able to stimulate yang and help fire. This is because of its warm nature and its ability to nourish yin. With this, yang follows yin and yang naturally becomes strong. Because of its ability to nourish, all symptoms and lumps will disappear immediately. Because of its nourishing, yang can be helped. Therefore, all spermatorrhea, penis pain, cold and heat can also be eliminated. If you say that fire is extremely weak, use this sweet and moist product, which is the same as cinnamon and aconite, and can effectively supplement yang, it is far from right. Moreover, since it is said to supplement yin, and the name of yin supplement is Cistanche deserticola, it is clear that because its power is not sudden, and its qi is specialized in moistening dryness, it is also suitable for constipation, but not for people with weak stomach. It is OK to call it nourishing yin, but it is not necessarily to call it supplementing fire.
 "Ben Cao Zheng Yi": Cistanche deserticola, "Ben Jing" mainly treats yin, mainly for fatigue and injury, nourishing the middle, nourishing the five internal organs, and strengthening yin, all of which are the functions of nourishing yin. Cold, heat and pain in the stem are kidney deficiency and cold diseases. Cistanche deserticola is heavy and descends directly into the kidney, warm and moist, without the harm of dryness and intensity, can warm and nourish the essence and blood and pass the yang qi, so it is said to benefit the essence and qi. For the main symptoms of lumps, salt can soften the hardness, enter the blood, and nourish the yin essence, warm and nourish the yang qi, so that the qi and blood flow smoothly and the blockage is not blocked. "Bie Lu" removes bladder evil qi, and also warms and nourishes the water palace cold evil. The waist is the home of the kidney, and kidney deficiency causes waist pain. Cistanche deserticola benefits the kidney, so it treats it. It is beneficial. Now, all woods are used to treat dysentery. It is the stagnation of stagnation and discomfort, not the self-benefit of diarrhea. Cistanche is a smooth bowel. Dysentery is stagnation, so it is better to dredge it rather than to fix it. It can also nourish the five internal organs without focusing on attacking it. It is suitable for people with chronic dysentery whose qi is already weak and the stagnation is not completely gone. It is not a cure for dysentery caused by summer heat, dampness and heat. Cistanche is a very moist product. It is salted in the market so that it can be stored for a long time. Ancient books all say that it is slightly warm. Now, it is salty and has been soaked for a long time. The warm nature has been completely eliminated. Even if it is rinsed very lightly, its original nature will be completely eliminated. Therefore, the various effects of replenishing yin and stimulating yang that the ancients said are all very weak. It has been used and transformed, and it can no longer be discussed in the same way as the original quality. However, the salty taste can descend, and the slippery taste can clear the intestines, so it is mainly used to relieve constipation, which is quite effective. Moreover, its nature is warm and moist, which can benefit yin and yang, so it can clear the bowels without hurting body fluids, which is particularly unique. Since the Song Dynasty, Cistanche has been used to treat leukorrhea and uterine bleeding, and even metrorrhagia and hematuria, because it can replenish yin and support yang, and it is said to have the effect of restraining and consolidating yin. You should know that slippery products are more than just for dredging, how can they consolidate and astringe? The "Ben Jing" eliminates cold, heat and pain in the yin, and it replenishes yin and dredges yang. If it is unblocked, there will be no pain. Later generations extended its meaning and mistakenly believed that it was a great tonic, and wanted to treat slippery and prolapse with dredges, which is a fallacy.
 "Compendium of Materia Medica": This substance is nourishing but not harsh, so it is called "Cong Rong". Before using it, you must soak it in clear wine overnight. In the morning, use a palm brush to remove sand and floating shells, split the center, and remove a layer of white film like bamboo grass. This can block the qi in front of people's hearts and make people gasp. Steam it, take it out from noon to dusk, and roast it with butter.
