Mix it with honey wine, steam it nine times and expose it nine times, make honey pills, swallow it with wine on an empty stomach, and take as much or as little as you like. It is good at treating stroke, crooked mouth and eyes, and removing dampness, paralysis, waist and leg pain and numbness. The raw one is boiled in wine, and it can expel tetanus in an emergency. It can be used to disperse the poison of hemp, carbuncle, edema, tiger bite, dog bite, spider and insect poison, or mash it and seal it, or boil it in water, or apply it in powder form. Its sweeping power is so good that it seems to be not good for people with weak vital energy.
 "Compendium of Materia Medica Shengya": Chu people call pigs "狶" and call smells "莶". The kidneys are used to store pigs, and the kidneys are smelly and rotten. It is a medicine for the kidneys. It tastes bitter, its air is cold, and its nature is moistening and descending. It is also a medicine for the kidneys. Treating hot insects as a scourge is like a stinging insect that damages my ears. The classics say: People with kidney deficiency have a heart that is as if they are hungry, upset and unable to eat. Moxibustion will force them to eat raw meat. Kidney deficiency causes leg swelling and coldness. In fact, the bones and qi are essence. Therefore, those who stay in shape will first indulge in qi in the kidneys and attack the essence in the bones. Then, they will be indulged and dispersed, and then they will get soft muscles and beautiful ears. If the wind passes through the liver, it will cause the fascia to relax. This is to use qi to affect the shape, and also to use the shape to affect qi. Assisting the liver is the mother, which is to replenish the shape of the kidney. When the shape is complete, the spirit is complete, and the five shapes are like one.
 "Ben Cao Jing Shu" says: Xiwei is a Yang grass. It is born by the vitality of Shaoyang, so its taste is bitter and cold, and should not be poisonous. It is an important medicine that enters the blood to dispel wind and dampness, and activates blood circulation. When dampness and heat are strong, insects will be born, and dampness will make people feel irritated and unable to eat. Spring medicine is originally suitable for wind and transformation. Wind can overcome dampness, and bitter and cold can eliminate heat, so it is the main medicine. The classics say: The dampness of the ground, when it is felt, will harm people's skin, flesh, tendons and veins. Therefore, Su Song treated liver and kidney wind, paralysis of the limbs, pain between bones, weakness of the waist and knees, and large intestine qi. Cheng Ne used it to treat stroke. Zhang Yong used it to lighten the body and keep the face. The effect has been known in the past, and the effect is seen again in the present. The magic is that it moves without leaking, the fragrance can open the spleen, the evil is gone and the body is at peace, and the effect is doubled.
 "New Compendium of Materia Medica": Xishen tastes bitter, has a cold nature, and is slightly toxic. Some say it is hot in nature, so it is not non-toxic. It enters the kidney. It can treat sudden stroke, crooked mouth and eyes, long-term dampness and arthralgia, sore waist and feet, and heat and fullness. However, it is especially inappropriate to take and use it to disperse the true qi of the human body. Why is it included in this compilation? Because there are very few drugs for the kidney meridian among medicines, and the kidney is particularly difficult to treat when it is attacked by wind evil and dampness. For the time being, it is kept to treat rheumatism in the kidney. I don't know why the ancients praised this product, and modern people also like to use it, and some praise that taking it a hundred times will make your ears and eyes bright, and taking it a thousand times will make your hair and beard black, and drive away wind and dampness. It is still a casual word, but it is really a murderous word.
 "Compendium of Materia Medica" says: Siegesbeckia specifically enters the liver. It tastes bitter and pungent, and is cold but not warm, so it is written in the book that it must be steamed and dried for nine days. The number is exhausted at nine. If it is processed with wine and honey, the turbid yin qi can be removed, and the fresh fragrance begins to appear. Therefore, it is only suitable for rheumatism of the liver and kidney, and can also be seen in numbness of the limbs, cold pain in the tendons and bones, weakness in the waist and knees, rheumatism and sores. It is because its bitterness can dry dampness, its coldness can remove heat, and its pungentness can disperse wind. If it is not rheumatism, but there are symptoms such as weakness in the waist and knees, it belongs to blood deficiency and cannot be used with pungent and dispersing flavors. However, it can be used cooked, and its nature is not very harmful to the body. If it is used raw and not processed, it will make people nauseous, which is important to know.
