 "Compendium of Materia Medica": The diseases that Achyranthes bidentata treats are generally tonic for the liver and kidneys when used with wine, and to remove bad blood when used raw. These are the only two. It is used to treat pain in the waist and knees, atrophy of the feet, loss of yin, incontinence, chronic malaria, and shortness of breath due to injury. Isn't it because of its ability to tonify the liver and kidneys? It is used to treat masses, pain in the heart and abdomen, carbuncle, malignant ulcer, wound, fracture, sore throat and teeth, hematuria, and menstrual and pregnancy diseases. Isn't it because of its ability to remove bad blood?
 "Ben Cao Jing Shu": Achyranthes bidentata, can nourish by walking, and is good at descending, so it enters the liver and kidney. It is used to treat cold and dampness, paralysis, cramps in the limbs, and knee pain that cannot be flexed and extended. If the liver, spleen and kidney are deficient, the evil of cold and dampness will invade and cause paralysis, and the limbs will be cramped, and the knee pain cannot be flexed and extended. This medicine moves downward, and it can expel cold and dampness and eliminate paralysis. In fact, nourishing the liver can relax the tendons, descending can regulate the knees, and blood circulation can stop pain. Expelling blood and qi, it is said that it can ventilate stagnant blood. In detail, the nature of the medicine, qi should be numbness. Injury, heat, fire, rot, blood scorch and dryness are diseases, blood circulation and vitality, pain will stop. Entering the liver to circulate blood, so it can cause abortion. Injury, lack of qi, male yin loss, and old people drowning are all signs of kidney deficiency. The brain is the sea of marrow. If the brain is not full, it will be empty and painful. The waist is the viscera of the kidney, and the spine connects the marrow to the brain. If the kidney is deficient and the marrow is less, the waist and spine will ache; if the blood is deficient and hot, the hair will turn white. If the body is weak and tired, the injury will be severe. The liver stores blood, and the kidney stores essence. If the liver and kidney are tonified, the blood will be sufficient and the essence will be full, and all symptoms will be cured. When the blood circulates, the menstrual period will flow and the blood clots will be dispersed.
 "Bencao Tongxuan" says: According to the five symptoms of stranguria, it is extremely difficult to see any effect. Only one or two grams of Achyranthes bidentata, add a little frankincense and boil it and drink it. After taking several doses, the symptoms will be relieved. It has the property of descending and can lubricate the orifices.
 "Pharmaceutical Chemistry": Achyranthes bidentata, sweet in taste, can nourish, astringent, bitter, and can move downward. It is used to enter the kidney. The kidney is responsible for storage, astringent essence, blood, and guiding all medicines downward. Raw use is purgative, and it is mainly used to treat urinary retention, leucorrhea, penis pain, blood stasis, stagnation, lumps, amenorrhea, and postpartum nausea, taking its function of promoting blood circulation downward. When cooked with wine, it is tonifying, and it is mainly used to treat cramps in the limbs, pain in the waist, knees, and legs, pain in the bones and tendons, dry thirst caused by malaria, damp-heat paralysis, and inadvertence in the elderly, taking its function of nourishing blood and yin.
 Ben Jing Feng Yuan: Achyranthes bidentata, although it moves downwards and moves the tendons, is a slippery product, and is not suitable for those whose essence and qi are not solid. Steamed with wine, it can nourish the tendons, and used raw, it can remove bad blood. Wai Tai uses it to treat malaria caused by long-term fatigue, Elbow Back uses it to treat sudden and violent diseases, Yan Nian uses it to remove the placenta, Wei Sheng uses it to pound and apply to fractures, Mei Shi uses it to pound and apply to wounds, Qian Jin uses it to pound and apply to poisonous swellings, and Ji Yan uses it to clear and relieve urination, all of which are taken for its slippery nature, blood-clearing and detoxifying effects. Although it strengthens the yin and tendons, it is forbidden to use it for qi deficiency and sinking, easy diarrhea, nocturnal emission and spermatorrhea, and metrorrhagia during pregnancy. Only the one produced in Sichuan is similar to Dipsacus as a smell and shape, so there is no risk of slippery essence. The kidney is responsible for storage, and the liver is responsible for dispersing and dispersing. This flavor is dedicated to dispersing and dispersing, and has no function of solidifying and benefiting. The world mistakenly claims that it benefits the kidney, and often uses it in medicines for cultivating the lower yuan, which is no different from delaying thieves from entering the house.
 "Ben Jing Xu Shu" states: "Both paralysis and arthralgia are diseases between tendons and joints, and cold and dampness may be transformed or not. If it is not transformed, it will infiltrate the tendons and joints and cause disease, while if it is transformed, it will burn the tendons and joints and cause disease." "Su Wen" states that arthralgia is mostly caused by infiltration, and paralysis is mostly caused by burning. The magic of Achyranthes bidentata in treating this disease is that it does not matter whether it has been transformed or not, but it can cure all diseases that are pain between tendons and joints and cannot be flexed or stretched. The main points of the "Bie Lu" are all to melt the purpose of "Ben Jing" and expand it. Generally speaking, the strong will be softened, the dry will be moistened, the upper will be lowered, the broken will be connected, and the blocked will be unblocked. It will suppress the fire to make it approach the water and help the water to flow.
 "Medical Records of Chinese and Western Medicine" states: Achyranthes bidentata is originally a tonic, but it is good at guiding qi and blood downward. Therefore, when using medicine to guide it downward, it is always used to guide the meridian. Therefore, it is good at treating kidney deficiency, back pain, leg pain, or knee pain that cannot be flexed or extended, or leg atrophy that cannot stand. It can also treat women's amenorrhea and blood deficiency, and induce labor. It is also good at treating stranguria and promoting urination, all of which are the effects of its good downward force. However, "Bielu" also says that it can eliminate brain pain, and Shizhen also says that it can treat mouth sores and toothache. Why? All these symptoms are caused by the rise of qi and blood with fire and heat. Heavy use of Achyranthes bidentata can guide the qi and blood downward, and can also guide the floating fire downward, so it can be cured. I realized this principle and used it to treat brain congestion, and combined it with ochre, dragon bone, oyster and other heavy and astringent products, all of which worked immediately, and the number of cured patients was countless. Because of its nature of focusing on downward flow, any symptoms of loose qi in the lower burner and all kinds of slippery symptoms should be avoided.
 "Compendium of Materia Medica" states: Achyranthes bidentata is a dredging and descending herb. It is used to treat diseases of stagnation of qi and blood. "Ben Jing" says that it treats cold and dampness, and it should be used as a typhoid fever according to "Yu Lan". It treats paralysis and numbness caused by dampness flowing into joints, cramps in the limbs, and knee pain that cannot be flexed or extended. It is a specialist in dredging stagnation, and it is not the same as the paralysis caused by the exhaustion of qi and blood. They can be discussed together. However, all paralysis and numbness have two levels: dampness obstruction and blood deficiency. For dampness obstruction, we must expel evil and make it circulate. For blood deficiency, we must nourish and help it flow. Achyranthes bidentata is bent and can reach everything. It is the main one for expelling evil, and it is also the auxiliary one for nourishing the body. Therefore, paralysis, numbness, bone pain, and muscle spasm are all symptoms that cannot be treated without this herb. Expelling blood and qi is to clear the stagnation. It is also to help the circulation of blood for treating injuries caused by heat and fire. From this, we can know that the nature of Achyranthes bidentata is cold and cool. Therefore, it can cure heat injury and fire injury. If cold and dampness are diseases, it must not be its responsibility. The error in the above text is more obvious. The ability to induce abortion is due to its sliding downward force. "Bie Lu" says that the treatment of wounds with less qi is also for those with damp heat blocking and the middle qi not being released. It is not suitable for those with insufficient righteous qi and sinking of clear yang. It cures male yin loss, and also for those with excessive heat damaging yin, not for those who can replenish the true yin of the liver and kidney. Elderly people lose their urine, which is caused by blocked tunnels and urinary retention. It must not be a sign of weak lower yuan and bedwetting. The so-called tonifying the middle, continuing the dead, filling the bone marrow, benefiting the essence, and benefiting the yin qi are all about the stagnation and the prosperity of righteous qi. Never mistake Achyranthes bidentata as a filling product. Those with pain in the brain are mostly due to the rise of yang evil. If Achyranthes bidentata moves smoothly, the qi and fire will naturally subside. Pain in the waist and spine is also due to the stagnation of the meridians. Achyranthes bidentata can clear the meridians and collaterals, and the joints will benefit. It also treats menstrual obstruction, blood clots and other symptoms. This is the true meaning of breaking up blood stasis and removing stagnation. All of this should be considered from the perspective of dredging, and the true function of Achyranthes bidentata is clear.
