Baicalin: Baicalin is preferred for clearing lung heat. Baicalin contains baicalinone and baicalin, which can inhibit mast cell degranulation, block the release of histamine and slow-reacting substances, and has a wide range of immunomodulatory effects, and is a promising herbal medicine for treating pulmonary fibrosis. Salvia: Salvia has the effect of protecting pulmonary capillary endothelial cells and pulmonary type II epithelial cells, as well as reducing pulmonary hypertension. These important pharmacological effects make it not only have a therapeutic effect on the early formation of pulmonary fibrosis, but also treat pulmonary hypertension in advanced patients, and it has been proved that salvia has better protection in preventing pulmonary fibrosis caused by radioactive lung injury and pulmonary fibrosis caused by Pingyangmycin It has been demonstrated that Salvia miltiorrhiza has good protective effect in preventing pulmonary fibrosis caused by radiation lung injury and pulmonary fibrosis caused by pinyin. It has been reported that IH764-3, the effective monomer of Salvia miltiorrhiza, has significant preventive and therapeutic effects on pulmonary fibrosis caused by bleomycin in rats. Further studies showed that IH764-3 inhibited the secretion of fibroblast growth factor by pulmonary cytomacrophages and had a blocking or inhibiting effect on the proliferation of fibroblasts stimulated by pulmonary cytomacrophages. It has been observed that Salvia miltiorrhiza and ultrashort wave electrotherapy have a protective effect on pulmonary fibrosis induced by Pingyangmycin. Chuanxiong and Angelica: Dai et al. administered Chuanxiongzine injection and Angelica injection intraperitoneally to bleomycin-molded rats and set up normal and model groups, and each group was executed after 4 weeks for histopathological examination and quantitative analysis of alveolitis and interstitial fibrosis by electronic computer image analyzer. It is suggested that the efficacy of Chuanxiongzin and Angelica sinensis in treating interstitial fibrosis is satisfactory and the side effects are small, which provides a basis for the herbal treatment of pulmonary fibrosis with licorice. The reason for this is that the above deficiency cannot benefit the lower part of the body. This is cold in the lung, must glare, more saliva, licorice dry ginger soup to warm it.” Licorice contains a large amount of glycyrrhetinic acid, which has adrenocorticotropic hormone effect, and also contains LX component, which can inhibit IgE and histamine synthesis. Clinical application has many pharmacological effects such as coughing and asthma, anti-allergy, anti-inflammation, etc. It is an herbal medicine for the treatment of pulmonary fibrosis, but the application amount should not be too much (not more than 10 grams), large amount and long-term application can cause edema and excessive stomach acid. Colchicine: This drug inhibits collagen formation and regulates the extracellular matrix in vitro and in animal models; it also inhibits the release of macrophage-originated growth factors and fibronectin in cultured alveolar macrophages from patients with nodal disease or IPF Oral colchicine 0.6 mg once or twice daily for the treatment of IPF or in patients who are resistant to hormones, either alone or in combination with immunosuppressive agents. Radix et Rhizoma: Zhong et al. observed the effect of intraperitoneal injection of Radix et Rhizoma T4 monomer on pulmonary histopathology and pulmonary hydroxyproline content in rats with pulmonary fibrosis model. Bitter ginseng bases: protective effect in rats with interstitial lung fibrosis. Bitter ginseng alkaloids attenuated BLM-induced pulmonary fibrosis in rats, and this effect was possibly achieved by improving the oxidative stress status in BLM rats and reducing DNA damage in PBMCs of rats with interstitial lung fibrosis. Mulberry leaf: It has achieved efficacy in the treatment of rubbery legs formed in the late stage of filariasis, and is believed to reduce fibroplasia and tissue mechanization, and some people have used it in the treatment of this disease. Radix Panax notoginseng: It has the effect of relieving cough and resolving phlegm, and is found in Xiaoqinglong Tang, Xingxiang Su San, Shenggan Mahuang Tang, Su Zi Qi Qi Qi Qi Down Soup, Qing Qi and Phlegm Soup, Polishing Phlegm Soup, and Jinshui Liujun Decoction. The phenolic alkaloids extracted from the powdered-leaved rotunda vine of the family Fabaceae had a strong inhibitory effect on the formation of collagen fibers in experimental silicosis in rats. In addition, in the extraction of alkaloids from the leaves of Guizhou fine leaf ten gonglao, the Chinese herbal medicine mulberry bark, Chaihu, Pueraria lobata and Houpao have a better therapeutic effect on this disease. The principle of the above drug selection is still based on evidence-based treatment.
