1, radical method
It is equivalent to the "clearing fu-organs and clearing heat" of traditional Chinese medicine, that is, the purpose of reducing fever is achieved through drugs that relieve constipation through bitter cold.
It is mainly suitable for patients with high fever and constipation. If the patient has high fever, excessive sweating, constipation, abdominal distension, abdominal pain, refusal to press, or even nonsense, the tongue coating is yellow and rough, and the pulse is smooth and strong. It's like having more firewood in the pot. If the firewood is removed, the fire will go out. Therefore, rhubarb, mirabilite and other drugs are often selected, or mixed with heat-clearing prescriptions to promote defecation, diarrhea and heat accumulation, so that pathogenic heat can be reduced from bottom to top, which can achieve the effect of removing fire and reducing fever; Furthermore, relaxing bowels and removing fire can protect vaginal fluid, just like preventing excessive internal heat from drying up the water and limiting the temperature rise, it is also conducive to reducing fever.
2, Tang Yang cooking method
It is equivalent to the "evacuation and antipyretic method" of traditional Chinese medicine, that is, the drug of medicinal Xin San is used to achieve the purpose of antipyretic. It mainly includes two contents:
First, the sweating and antipyretic method is suitable for patients with exterior syndrome. Common fever coexists with aversion to cold and fear of cold, and anhidrosis or unsmooth sweating is caused by external evils. Due to the different nature of pathogenic factors and the differences of patients' physique, they can be divided into two categories: wind-cold exterior syndrome and wind-heat exterior syndrome. The former has obvious aversion to cold, generally no sweat, headache, sore limbs, stuffy nose, no thirst, sore throat and tight pulse. The latter has obvious fever, generally sweating, headache, thirst, sore throat and floating pulse. Different drugs should be selected according to the difference of cold and heat, such as pungent and sweaty drugs commonly used in wind-cold exterior syndrome, such as ephedra, cassia twig and notopterygium root; Wind-heat exterior syndrome commonly uses pungent and cool sweating drugs, such as Bupleurum, Cimicifuga, mint and so on. By sweating to eliminate pathogenic factors, the pathogenic heat is exposed, and the fever is correspondingly reduced, so as to achieve the effect of reducing fever, which is in line with the therapeutic principle of "If the body is coke, the sweat will also disperse" in Huangdi Neijing, a classic work of traditional Chinese medicine. The sweating method is especially effective for those who have no sweat and high fever.
Second, the method of promoting fever and reducing fever is suitable for patients with internal heat stagnation, which is often manifested as fever, dysphoria in chest and diaphragm, dry mouth and cleft lip, red face, yellow tongue pain and rapid pulse. Mint, Cimicifuga, etc. It can be added to the heat-clearing prescription as appropriate to strengthen the function of evacuation and heat-clearing, which conforms to the treatment principle of "fire depression" mentioned in Huangdi Neijing. However, it should be noted that although sweating antipyretic method is very commonly used and has a good antipyretic effect, excessive sweating will damage body fluids, so it should be used with caution for patients with physical weakness.
3, the law of hot and cold
It is also one of the most commonly used antipyretic methods in Chinese medicine, that is, using cold drugs (sweet or bitter cold) to achieve the purpose of antipyretic.
Mainly suitable for patients with fever but not aversion to cold. If you see high fever, excessive sweating, thirst like cold drinks, and heavy pulse, it is a syndrome of excess heat hurting body fluids. At this time, you can't use sweating to reduce fever, but use sweet cold to reduce fever, such as gypsum, radix rehmanniae and radix ophiopogonis. If you see high fever, dysphoria, dry mouth and throat, constipation, urinary fever, red tongue with yellow fur and strong pulse, it is a syndrome of excessive heat toxin, and it is appropriate to use bitter cold and heat-clearing methods, such as Coptidis Rhizoma, Scutellariae Radix, Cortex Phellodendri and Gardenia. Because this medicine is cold and easy to hurt the spleen and stomach, we should pay attention to the right amount.
Finally, it is worth pointing out that the above three methods are all applicable to excess heat syndrome, but not to deficiency heat syndrome; It can be used alone in clinic, and the antipyretic effect will be better if it is used in combination according to the specific situation. In addition, when patients are sweating with high fever, Chinese medicine does not advocate the use of cold compress methods such as ice packs, so as not to affect sweating and is not conducive to reducing fever.
