1 cough relieving
Ancestors once compared lungs to clocks. As the saying goes, "the lung is like a clock, and it will ring when it is hit." Cold and heat in exterior and interior, and seven internal injuries can all affect the lungs, making the lung qi lose its normal function of dispersing and calming the nerves, which is caused by cough. Cough due to adverse qi treated by Asari is recognized at home and abroad as the syndrome of exogenous cold pathogen and endogenous cold, and Xiaoqinglong Decoction is its representative prescription. The structure of this prescription is divided into three groups One group of drugs is "exogenous fever is difficult to understand" in Treatise on Febrile Diseases, the second group is "dampness under the heart" in Treatise on Febrile Diseases, and the third group is "Radix Paeoniae Alba and Fructus Schisandrae Chinensis", which is sweet and astringent, alleviating the violent nature of drugs and making them control the main body. However, Herba Asari is blind and has a unique meaning in the prescription. The first meaning is to help Magway solve the table; The first meaning is to help Jiangxia drink; The bitter taste of Schisandra chinensis, combined with the pungent powder of asarum, is intended to make the lungs return to normal, and the cough will stop on its own, which is the third meaning. Zhongjing's wonderful use of drugs has been fully reflected in this respect. There are two common problems for doctors to treat cough: one is to use a set of prescription drugs to stop cough; Second, it is better to use drugs that clear away heat and resolve phlegm than products that are pungent and dry. For example, snake gall, Fritillaria cirrhosa liquid and Fritillaria cirrhosa loquat cream are mostly cold medicines. Hot cough may be effective, and cold cough will aggravate the condition. Both of them are wrong in losing the spirit of syndrome differentiation and treatment.

Asari has a good analgesic effect. It is used for toothache caused by wind and fire, with symptoms of swollen gums, thirst, red tongue and slippery pulse. Gypsum, Schizonepeta tenuifolia, Radix Saposhnikoviae, Herba Menthae, Rhizoma Chuanxiong, Radix Paeoniae Alba, Nidus Vespae, Radix Angelicae Dahuricae, Scutellariae Radix, Cimicifuga Rhizoma and Glycyrrhrizae Radix are commonly used in Asari, which belong to fire, and gypsum and Scutellariae Radix are suitable. Adding Radix Aconiti and Fructus Zanthoxyli to this prescription is also very effective for dental caries pain.
Asari is also commonly used for joint pain. According to Shennong's Herbal Classic, it is the main cause of arthralgia due to rheumatism. Both wind-cold dampness and wind-heat dampness can be used, but the dosage of cold syndrome can be increased. The latter is only used to dredge meridians and wash away accumulated damp heat, but the dosage should not be heavy, generally 3-5g.
North asarum is also a medicine for headache. Kou Zongshuang said that "treating shaoyin headache is like a god". In fact, wind-cold and wind-heat headaches are also commonly used, such as Chuanxiong tea powder and chrysanthemum tea powder in the local prescription.
4. Pain relief and healing
Stomach ulcers mostly belong to fire, but there is a difference between virtual fire and real fire. Real fire should be clear and appropriate, and virtual fire can be replenished and collected. Coptis chinensis and Asari, one cold and one hot, have been broken, and a hair has passed, which has the effect of diminishing inflammation and relieving pain. In addition to oral administration, 3 parts of Coptidis Rhizoma and Asari 1 part can be ground into fine powder, and honey can be applied externally. For aphtha due to deficiency fire, it is often used together with decoction based on syndrome differentiation. Grind Asari 15g into fine powder, mix it with water and honey into paste, put it in gauze, stick it on navel, seal it with adhesive tape, and change it every two days, usually about three days, to cure oral ulcer.
Because the taste is pungent and scattered, it is good to pass the yang and disperse the knot. For some intractable diseases such as lupus erythematosus, eczema, tumor, Parkinson's disease, bradycardia and so on. Adding Asari to the syndrome differentiation and treatment prescription can improve the curative effect. Only those with yin deficiency and excessive fire and red tongue are prohibited.
Usage and dosage of Asari
1g~3g. Appropriate amount for external use, which can be ground into powder, blown nose or externally applied. In principle, the dosage of powder should be strictly controlled below 3g, and the decoction can be taken in large doses according to the patient's physique, condition and user's experience, but only if it is thoroughly fried. Methyl eugenol, elemene and safrole in Asari volatile oil are the main physiologically active components and the main toxic components. With the extension of decocting time, the volatile oil volatilizes more. The toxic component safrole is only 2% after decocting for 30 minutes, which is more volatile than its main effective component methyl eugenol. Pharmacology has proved that high-dose asarum is not only safe but also effective, which is consistent with the safe and effective result of overdose of asarum by many famous old Chinese medicine practitioners.
The dosage of asarum exceeds the pharmacopoeia. If you don't have sufficient experience or grasp, you should gradually increase the dosage from a small one. Appropriate dose increase can obviously improve the curative effect and shorten the course of treatment. If the dose is too small, it will delay the onset and make the disease last. But the principle of traditional Chinese medicine is safety first.
