 【Predecessors release medicine】
 "Compendium of Materia Medica" states: "Chrysanthemum can replenish yin, but it must be sweet. Do not use wild and bitter ones, as they will greatly damage the stomach qi."
 "Compendium of Materia Medica": "Chrysanthemum, in the past, was said to be able to remove wind and heat, and to benefit the liver and tonify yin. But few people knew that it could also benefit the metal and water organs. It replenishes water to control fire, and replenishes metal to calm wood. When wood is calmed, wind subsides, and fire is reduced, heat is removed. It can be used to treat various wind-induced headaches, and its purpose is profound and subtle."
 "Compendium of Materia Medica" states: "Chrysanthemum controls wind and wood, so it is an essential medicine for removing wind. Bitterness can relieve heat, sweetness can benefit blood, sweetness can detoxify, and neutrality is pungent, so it can also disperse knots. Bitterness enters the heart and small intestine, sweetness enters the spleen and stomach, neutrality and pungentness go to the liver and gallbladder, and also enter the lungs and large intestine. It is used to treat wind-induced dizziness, swelling and pain, loose eyes, tears, dead skin, aversion to wind, and dampness. All wind-induced dizziness and vertigo are related to liver and wood. Wind-relief medicines first enter the liver, and the liver opens the eyes. Wind is a yang evil, so it is bound to go up. Blood deficiency causes heat, and heat causes wind, so the wind and fire fight against each other. Pain that comes and goes is a sign of blood deficiency and qi stagnation. Bitterness can relieve stagnation, sweetness can benefit blood vessels, and pungentness can disperse deficiency heat. As for removing chest heat and restlessness, the heart governs blood. If it is deficient, the patient will suffer from restlessness. If the yin is deficient, the heat will be retained inside, so the heat is in the chest. If the blood is replenished, the yin will grow, and if the yin grows, the restlessness will stop. Bitterness and pungentness can relieve heat, so the restlessness and heat are relieved. It can calm the stomach and intestines, benefit the five meridians, regulate the limbs, and benefit the blood and qi. It can remove heat, dispel wind, benefit blood, and enter the heart, spleen, and liver. Raw pounded mulberry is the best medicine for treating furuncles, especially blood line furuncles, which are caused by wind and fire poison.
 "Pharmaceutical Chemistry": "Chamomile, take the white one, its body is light, tastes slightly bitter, has a peaceful nature, and is the most clear product. The "Classic" says that it is used to treat heat and clear. When the fever subsides, the qi is still warm. It can be used with mulberry bark to treat headaches and eliminate the remaining evil. It can be used with Astragalus to treat blurred vision and remove cataracts. It can help Adenophora to treat red intestines and stop bleeding. It can be used with Dendrobium and Lentils to improve eyesight and hearing, and regulate the limbs. Therefore, white chamomile should be used for lung qi deficiency. If it is yellow, it has a bitter taste and a light fragrance. It is mainly used to clear lung fire. All headaches, vertigo, nasal congestion, dampness of the skin, wind in the limbs, and pain in the shoulders and back are all caused by lung qi heat. This can clear and smooth the lung metal, and clearing the metal will control the liver wood. It can also treat sudden red eyes and swelling, eye pain and tears. Therefore, yellow chamomile should be used to clear lung heat."
 "New Compendium of Materia Medica": "Chamomile has a light and clear smell and slow effect. It must be taken for a long time before it works. It cannot be blamed for its quick effect. Only when used suddenly for eye pain, it works very quickly. For other cases, it works slowly before it works. Nowadays, people grow a lot of chrysanthemums, but they don't know that some tonic prescriptions use it. They also take it for tea, thinking it can improve eyesight. However, chamomile is not only for improving eyesight, but also can be used to reduce the stomach fire of Yangming. Because Yangming internal heat must be drained with yin and cold medicines, such as gypsum and rhizoma anemarrhenae. However, gypsum is too strong and too cold to damage the stomach qi. It is better to use 1 or 2 liang of chamomile flowers, together with Radix Glycyrrhizae and Radix Ophiopogonis, which can calm the fire in the stomach without damaging the stomach qi."
 "Compendium of Materia Medica: Records of 100 Kinds of Things" states: "All aromatic things can cure diseases of the head, eyes, and skin. However, all aromatic things are pungent and dry, but chrysanthemum is not very dry and strong, so it is especially suitable for diseases of the head, eyes, and wind and fire."
 "Compendium of Materia Medica" states: "The use of chamomile can be summed up in one word: it dispels wind. Although it is a product that dispels wind, its nature and flavor are sweet and cold, which is different from the pungent and dry ones such as Qiang and Ma. Therefore, it can be used to nourish the liver and kidneys and thistle.'
 "Compendium of Materia Medica" states: "All flowers are good for spreading and venting, but chrysanthemum can absorb and descend, calm liver fire, extinguish internal wind, and suppress the rebelliousness of wood qi. "Ben Jing" says that the main cause of dizziness is dizziness caused by yin deficiency and yang floating, qi and fire rising, and liver wind disturbing. It is not external wind evil that can make people dizzy. Swelling and pain are read together as three words of "shangfengtouxuan". Liver fire goes straight to the top of the head, causing dizziness, swelling, and pain. Yang flames rise straight up, and its momentum is the most violent. All headaches are nothing but the shaking of internal fire and wind, and chrysanthemum can cure it. It is difficult to have such power if it is not a calming and tranquilizing one. Eyes are about to fall out, which is the worst of liver yang internal wind. People say that headaches are so severe that they can cause blindness, but they know Some people also have protruding eyeballs that are shaped like bird eggs. Tears are also caused by Yin deficiency in the lower part, rising liver fire, and the lack of true Yin to absorb it. The function of wind and yang is to dredge and release it, so tears fall in the wind. These are all liver and kidney Yin deficiency, and the floating Yang is too strong. Only the bitter and dredging effect of chrysanthemum can absorb the virtual Yang and return it to the lower part, so it is an important medicine for ophthalmology. It can also treat dead skin muscles and rheumatism. The blood is hot and the collaterals are unclean, and gradually the accumulated filth becomes rotten. Chrysanthemum is bitter and pungent, and can open the collaterals and regulate the heat and toxicity in the blood. Then the filth will be removed and the dead skin muscles with numbness can be cured. Shi Wanwei clears the blood vessels, and the dampness in the numbness can be released. It is a very correct theory. However, this is a pure product that can clear the turbid blood accumulated in the meridians. It will not be cured overnight. It can be effective quickly, so we should not doubt the credibility of the classics because it has no immediate effect. "Bielu" says that it can treat low back pain that comes and goes, which means that it lasts for a long time. This is also due to insufficient kidney yin and dampness, so the pain continues. Chrysanthemum nourishes kidney yin and clears dampness and heat, so it is the main treatment. It can also treat chest heat and calm the stomach, which is of course the function of clearing and purging heat. Zhen Quan said that it can treat headaches caused by wind spinning in the head and falling to the ground, and pain in the skull. This is caused by liver yang internal wind headaches. There are those who go straight to the top of the head and feel that the skull is cracked. If the wind spins and falls to the ground, the blood will rush to the brain meridians and lose its perception and movement. It is also said that it can treat all wandering wind in the body, dissipate it, and benefit the blood vessels. This is a symptom of blood heat generating wind, and bitter purgation. Clear the eyes, and the wind will stop. Daming said that using it as a pillow can improve eyesight, and the leaves can also improve eyesight. Jiegu said that it nourishes eye blood and removes cataracts. Haizang said that it is used to treat insufficient liver qi. It also means nourishing liver yin and nourishing liver blood. Although its smell is refreshing, it is not a liver qi medicine. Zhongchun said that raw pounded mulberry is the best for treating furuncle, and blood line furuncle is especially important. According to the theory, furuncle is fire poison, and large doses of it must be cleared and resolved. Externally applied medicines such as honeysuckle vine, purslane, dandelion, grass car, hibiscus leaf, green chrysanthemum leaf, etc., are only for clearing heat and reducing swelling, and they are not specifically responsible for it. The blood line furuncle that Miao called is probably the red thread furuncle, which has a trace of red halo that rises from the mouth of the sore and goes straight over the elbows and knees. The treatment is mainly based on internal administration to clear the problem. But external treatment is not something you can rely on."
