Xianfang Huomingyin is known as the first prescription of surgery， also known as Shenxian Huomingyin and Zhenren Huomingyin. The earliest one was from Renzhai Zhizhi in the Southern Song dynasty. It was composed of 13 mainstream medicines such as Angelicae Dahuricae Radix， Saposhnikoviae Radix， Paeoniae Radix Rubra， and three modified medicines such as Rhei Radix et Rhizoma， Momordicae Semen and Astragali Radix. It has the effects of clearing heat and detoxifying， detumescence and ulceration， promoting blood circulation and relieving pain， and is mainly used to treat Yang syndrome. In this study， the bibliometrics method was used to systematically study the historical evolution， prescription composition， dosage， indications， decocting methods， administration methods， drug processing and ancient and modern applications of Xianfang Huomingyin. As for the drug origin， pangolin is consistent with the 2015 edition of Chinese Pharmacopoeia， the origins of the remaining drugs are consistent with the 2020 edition of Chinese Pharmacopoeia. According to the ancient and modern dosage conversion， the dosage of each drug is as follows：Angelicae Dahuricae Radix， Paeoniae Radix Rubra， Fritillariae Thunbergii Bulbus， Glycyrrhizae Radix et Rhizoma and Trichosanthis Radix， Olibanum of 4.13 g， Gleditsiae Spina and Myrrha of 2.07 g， Angelicae Sinensis tail（stir-fried with wine） and Citri Reticulatae Pericarpium of 6.2 g， Saposhnikoviae Radix（removing reed） of 2.89 g， pangolin（stir-fried with clam powder） of 4.14 g， Lonicerae Japonicae Flos of 12.39 g， or adding Rhei Radix et Rhizoma of 4.13 g and Momordicae Semen（shelled） of 3.3 g， adding Astragali Radix of 4.13 g for body deficiency. The above medicines were decocted with 450 mL of yellow rice wine to 300 mL， 1 dose for each time， 3 doses for each day， and warmed before or 0.5 h after meals， 1-6 doses， and discontinue medication as soon as get effect. Because this formula is easy to hurt the spleen and stomach， it should not be taken more. In the follow-up， it should be used in conjunction with Tuoli Xiaodusan， and other related symptoms of patients can be further improved through dialectical addition and subtraction. This formula has the efficacy of disinfection and pus discharge， removing blood stasis and relieving pain. All carbuncle gangrene without ulceration at the beginning， and for the empirical and heat syndrome. Modern applications involve more than 200 kinds of diseases with heat syndrome， emergency and excess syndrome as the main syndrome differentiation points in dermatology， peripheral vascular department and other departments. In a word， this paper studies the literature of Xianfang Huomingyin in order to provide a basis for its wider and deeper clinical application and development research.

Through data collection and collation combined with bibliometrics， this study conducted a series of textual research on Yanghetang， such as the name and origin， the evolution of prescription composition and modern clinical application. Yanghetang was first recorded in Bencao Yidu of WANG Ang in the Qing dynasty. In addition to Yanghetang， there were 3 bynames of Jiawei Yanghetang， Quanshengji Yanghetang and Zhenjun Yanghetang. Regarding the composition of the formula， a total of 4 versions of Yanghetang were collected. The first version is the 5 medicines version of Cervi Cornus Colla， Rehmanniae Radix Praeparata， Cinnamomi Cortex， Zingiberis Rhizoma and Ephedrae Herba in Bencao Yidu. The second version is the 7 medicines version of Waike Zhengzhi Quanshengji， changing Zingiberis Rhizoma to Zingiberis Rhizoma Praeparatum Carbonisata（ZRPC） and adding Sinapis Semen and Glycyrrhizae Radix et Rhizoma（GRR） on the basis of Bencao Yidu， and most of the Yanghetang is of this version. The third version is the 6 medicines version of Wushi Yifang Huibian， that is， on the basis of Bencao Yidu， Zingiberis Rhizoma is changed into ZRPC， and Sinapis Semen is added. The fourth version is the 6 medicines version in Yifang Jiedu， that is， on the basis of Bencao Yidu， Zingiberis Rhizoma is changed into Zingiberis Rhizoma Praeparatum， and GRR Praeparata cum Melle is added. Regarding the dose of Yanghetang， the doses of the medicines in Waike Zhengzhi Quanshengji was converted into the modern doses as follows：37.3 g of Rehmanniae Radix Praeparata， 1.87 g of Ephedrae Herba， 11.19 g of Cervi Cornus Colla， 7.46 g of Sinapis Semen， 3.73 g of Cinnamomi Cortex， 3.73 g of GRR， and 1.87 g of ZRPC. The origins of the above medicines are consistent with the 2020 edition of Chinese Pharmacopoeia. The processing specification of Rehmanniae Radix Praeparata is steaming method， ZRPC is ginger charcoal， Sinapis Semen is the fried products， and the rest of the medicines are raw products. The decoction method was verified by the decoction method in Chonglou Yuyao， which is similar in the time， and it is recommended that the above medicines should be added with 600 mL of water， decocted to 100 mL， and taken warmly 30 min after meal. For each dose， it is recommended to use 1-3 doses per day according to the doctor's advice in combination with clinical practice. The diseases involved in the ancient applications involved 42 diseases in 11 departments， including orthopedics， dermatology and gynecology， which were dominated by Yin-cold syndrome. However， the diseases involved in modern research also include 148 related diseases in 10 departments， such as orthopedics， obstetrics and gynecology， which is consistent with the ancient books. In recent years， the research hotspots of Yanghetang have focused on more than 10 fields， including osteoblasts， malignant tumors， wound healing， traditional Chinese medicine fumigation and so on， which are widely used. It is suitable for comprehensive research and development because of its rational formula composition， clear origin， processing and decoction method， and wide clinical application.
