 "Tangye Bencao": Angelica sinensis enters the Shaoyin meridian of the hand because its heart governs blood; enters the Taiyin meridian of the foot because its spleen binds blood; enters the Jueyin meridian of the foot because its liver stores blood. The head can break blood, the body can nourish blood, and the tail can circulate blood. If the user does not distinguish between them, it is better not to use them. If all of them are used, they can nourish blood with ginseng and astragalus; they can break blood with morning glory and rhubarb. The user should know that the assistants and assistants determine the divisions. With cinnamon, aconite, and cornus, it is hot; with rhubarb and sodium sulfate, it is cold. Only when Angelica sinensis is steamed with wine, it can treat headaches. Because all headaches belong to wood, it is treated with blood medicine.
 "Han's Medical Manual": Angelica is the main treatment for blood diseases. Sichuan Angelica is strong and can attack, while Qin Angelica is soft and can supplement. For this disease, wine should be used, and phlegm should be soaked with ginger juice. The same is true for Rehmannia glutinosa. Blood deficiency is supplemented with ginseng and stone fat. Blood heat is supplemented with Rehmannia glutinosa, turmeric, and Scutellaria baicalensis to continuously replenish the source of blood metabolism. Blood stagnation is supplemented with rhubarb. Women with fat bodies have blood turned into phlegm. The two flavors are soaked in ginger and supplemented with diuretics. In short, blood drugs cannot be abandoned. Therefore, the ancient prescription Siwu Decoction is the main ingredient, peony is the minister, Rehmannia glutinosa is divided into raw and cooked as the assistant, and Chuanxiong is the messenger. It can be said to be a classic.
 "Compendium of Materia Medica": Danggui is used to treat headaches. It is boiled with wine and taken for its clear and floating properties. It is used to treat heartaches. It is mixed with wine and taken for its turbid and half-sunk and half-floating properties. It is used to treat bleeding in urine. It is boiled with wine and taken for its sinking properties. There are naturally high and low differences. Wang Haizang said that Danggui is a blood medicine. How can it treat cough, reverse breathing and shortness of breath in the chest? Danggui has a pungent and dispersing taste. It is a blood medicine. Moreover, cough, reverse breathing and shortness of breath are caused by yin deficiency and yang having nowhere to attach. Therefore, using blood medicine to replenish yin will harmonize the blood and lower the qi.
 "Compendium of Materia Medica": All diseases that are worse at night are blood diseases, so it is appropriate to use it. All diseases that are weak and cold are caused by the Yang having nowhere to attach, so it is appropriate to use it. The cold and heat of warm malaria are not outside the skin and in the muscles, but are washed in the skin. The skin is where the Ying Qi gathers. If warm malaria lasts for a long time, the Ying Qi will be weak, and the cold and heat will fight each other. Sweat and wash, and use blood medicine to nourish the Ying, then the Ying will be harmonious and in harmony with the Wei. If the Ying and Wei are in harmony, why can't warm malaria be stopped?
 "Compendium of Materia Medica": Angelica sinensis, its taste is sweet and heavy, so it can specifically nourish blood, its qi is light and pungent, so it can also promote blood circulation, and it is a qi medicine in the blood, and it is also a holy medicine in the blood. Generally speaking, it can nourish blood, nourish qi and produce essence, calm the five internal organs, strengthen the body, and benefit the mind. It is suitable for all diseases with physical deficiency. It can be used to attack, so it can relieve pain and relieve constipation, benefit the tendons and bones, and treat symptoms such as cramps, paralysis, dryness, and astringency. For those with deficiency of the Ying and unresolved exterior, it can be assisted with Chai, Ge, Ma, Gui and other agents, which can greatly disperse the heat of the exterior defense, and for those who cannot restrain the exterior, it can be assisted with rhubarb and the like, which can also consolidate the exterior. However, its qi is pungent and moving, so those who want it to be quiet should avoid it, and those who are slippery and good at moving, and those who have loose stools should avoid it. For those with strong fire in the yin, Angelica sinensis can move blood, which is not suitable. For those with deficiency of yang in the yin, Angelica sinensis can nourish blood, which is indispensable. If blood stasis causes dysentery, this medicine should be used. The key is the words "movement" and "slippery". If women have blood stasis during menstruation, or are about to give birth, or have occipital pain after delivery, this medicine should be used as the main ingredient.
 "Compendium of Materia Medica" states: "Danggui is used for body protection and replenishment, while its tail is used for circulation and removal of blood stasis, and its head is used for ascending. It is appropriate to raise the yin and yang in cases of blood in stool, blood in urine, metrorrhagia, etc. If the qi and fire rise and float in cases of vomiting blood and nosebleed, it is better to help warm the yin and yang. The word "hemostasis" should be used according to the symptoms, and it is not advisable to stick to the word "stop" and mistakenly think that it can do everything. Moreover, in cases of blood loss, the qi and fire rush and disturb the blood vessels, and the circulatory system does not follow the old path. In fact, most cases are caused by the strong smell of angelica. It is too much to move, but not enough to stop.
