 "Bencao Yanyi": When using the root of Gastrodia elata, it is necessary to use it with other medicines as auxiliary drugs, and then the effect will be seen. It is still necessary to add it and use it. People may pickle it with honey as a fruit, or steam or cook it and eat it. Those who use Gastrodia elata will get it if they think deeply about it.
 Li Gao: For those with liver deficiency, Gastrodia elata and Chuanxiong should be used to replenish the liver. It has four uses: to treat wind-heat headaches in adults, wind-epilepsy and palpitations in children, paralysis and insensitivity due to wind, and speech problems due to wind-heat.
 "Compendium of Materia Medica": Gastrodia elata is a medicine for the Qi of the liver meridian. "Suwen" says that all wind-induced dizziness and vertigo are related to wood. Therefore, Gastrodia elata enters the Jueyin meridian and treats various diseases. According to Luo Tianyi, "dark eyes and dizziness are caused by internal wind deficiency, which can only be cured by Gastrodia elata." Gastrodia elata is a wind-fixing grass, so it is a magical medicine for treating wind. Nowadays, some people who take Gastrodia elata for a long time will have red spots all over their body, which is the proof of its wind-dispelling effect.
 "Pharmaceutical Chemistry": Gastrodia elata, with mild and gentle qi, "Classic" says, "The liver is bitter and urgent, and it can be relieved with sweetness." Use this to relieve liver qi. The liver belongs to wood, and the gallbladder belongs to wind. If the liver is deficient, the liver will be urgent and strong, and it cannot nourish the gallbladder, then the gallbladder will be moved by wind, just like the wind in the sky, which is the wind and wood qi. Therefore, all wind dizziness belongs to the liver wood, which is caused by the wind of the liver and gallbladder, not the wind of the weather. Therefore, liver disease causes tense tendons, and this sweet and mild method can be used to relieve its hardness, which can nourish the liver and gallbladder, and is a magical medicine for calming wind. If you have a stroke, epilepsy, convulsions, headache, and dizziness, they are all symptoms of liver and gallbladder wind, and they can all be treated with this. If the liver is very urgent, use Coptis chinensis to clear its qi. In addition, it can reduce body weight, has a light taste and can clear the waist and knees, and can smooth the blood vessels. It can also dredge all wind-heat stagnation in the joints. It is also a magical medicine for blood deficiency.
 "New Compendium of Materia Medica": Gastrodia elata can stop dizziness, cure wind and dampness, treat muscle and bone cramps and paralysis, dredge blood vessels, and open the orifices. The rest is not entirely reliable. However, when the external evil is very strong and blocks the meridians and blood vessels, how can we guide the meridians without Gastrodia elata, so that the flavor of attacking and replenishing qi and blood can directly enter the affected area? In short, Gastrodia elata can best remove the external evil and expel the phlegm inside, but people with both qi and blood deficiency should never use it lightly.
 "Compendium of Materia Medica" states: The smell of Gastrodia elata is said to be pungent and warm in ancient times, probably because of the red arrow in "Compendium of Materia Medica". "Kaibao" and Zhenquan said that it is used to treat rheumatism, cold paralysis and other symptoms, all because of the two words "pungent and warm", so it is regarded as a product that can dispel wind and dampness, warm and relieve numbness. However, the ancient and ancient scholars also said that it is used to treat dizziness and headache caused by virtual wind, so it calms the liver and calms the wind, which is contrary to the method of dispelling wind, relieving numbness and dispersing. If it is really pungent, warm and dispersing, then it is used to treat dizziness and headache caused by virtual wind, which would not help it rise and expand its flame? Why did Luo Tianyi say that dark eyes and dizziness are caused by internal wind deficiency, and only Gastrodia elata can cure it? From this, we know that if it is wind, cold and dampness, numbness and paralysis, it is not Gastrodia elata that can cure it. The texture of Gastrodia elata is thick, solid, clear, smooth and rich in fat, so it can calm people down, nourish fluids to calm internal wind, so it is called Dingfengcao, and it can cure virtual wind, which is not a lie. Nowadays, it is often used to treat blood deficiency and dizziness, and children's heat, phlegm and wind shock, and it is effective. Therefore, Zhen Quan used it to treat speech confusion, fright and loss of will, and Dong Yuan used it to treat wind-heat and speech disorders, all of which are based on its ability to nourish yin and fluids, and calm internal wind. The theory that the smell is pungent and warm is based on the old saying of Chijian. In fact, it is not pungent at all, and the warmness is also a lie.
