Résumé
Due to the difference between the system of weights and measures， and the dosage of clinical prescriptions of traditional Chinese medicine in various historical periods， the dosage and conversion standard of prescriptions in past dynasties are different. Therefore， when discounting the dosage of famous classical formulas， the principles of inheriting the essence， making the past serve the present， linking the past and the present， and forming a consensus should be followed， firstly， the dosage of the prescription was converted according to the weights and measures system of the past dynasties. If the converted dosage significantly exceeds the provisions of the 2020 edition of Chinese Pharmacopoeia， then on the premise of ensuring that the proportion of the original prescription drug dosage remains unchanged， the conversion shall be based on expert consensus and drug safety evaluation. For drugs measured in non-standard units， a conversion range is provided based on comprehensive literature analysis and physical measurements. For the conversion of service volume， the original text was used as the basis for the conversion with reference to the measurement standards of different eras. If the original dosage is not clear， the converted dosage will be determined based on the historical evolution of the formula， referring to relevant ancient books， and combining modern applications. Eventually， the converting standard for famous classical formulas was determined as follows：during the Han and Tang dynasties， one Liang（两） was equivalent to 13.8 g and one Sheng（升） was equivalent to 200 mL， in the Tang dynasty， one Fen（分） was equivalent to 3.45 g， during the Song， Jin and Yuan dynasties， one Qian（钱） was equivalent to 4.13 g and one Zhan（盏） was equivalent to 300 mL， during the Ming and Qing dynasties， one Qian（钱） was equivalent to 3.73 g， and one Bei（杯） and one Zhong（盅） were equivalent to 200 mL. For drugs recorded in non-standard units of measurement， it is necessary to conduct actual measurements to determine their conversion standards based on comprehensive analysis to determine their origin. If necessary， different records of the dosage of drugs with the same or similar efficacy and indications in medical books of similar ages can be used to assist in determining the conversion standards. The analysis of the principle of dosage conversion for Chinese medicine is helpful for the clinical application and development of famous classical formulas.
Résumé
Yigongsan is derived from Xiaoer Yaozheng Zhijue written by QIAN Yi in the Northern Song dynasty， which is the No. 3 formula in the Catalogue of Ancient Famous Classical Formulas（The Second Batch of Pediatrics） released by the National Administration of Traditional Chinese Medicine（TCM） in September 2022， and it can be developed as a class 3.1 new TCM drug. By referring to ancient medical books and modern literature， this study conducted herbal textual research on Yigongsan from five aspects， including historical evolution， origin and processing， dosage conversion， usage and preparation methods， and functional application， then formed the key information table of this formula， in order to provide reference for the development of reference samples and preparations of Yigongsan. Based on the results of the study， it is recommended that Panax ginseng should be removed the basal part of stem（rhizoma）， Poria cocos should be removed the peel， Citrus reticulata should be cut into shreds and Glycyrrhiza uralensis should be used. According to 4.13 g/Qian（钱）， 1 g/slice for ginger， 3 g for each jujube and 300 mL/Zhan（盏）， the doses of Ginseng Radix， Poria， Atractylodis Macrocephalae Rhizoma， Glycyrrhizae Radix et Rhizoma， Citri Reticulatae Pericarpium， Zingiberis Rhizoma Recens， Jujubae Fructus were 1.652， 1.652， 1.652， 1.652， 1.652， 5， 6 g， and the total amount was 19.26 g. The decocting method was to crush the medicinal materials into fine powder with 50-80 mesh， add 300 mL of water and decoct to 210 mL for each dose， then remove the dregs and take it warmly. This formula was recorded in ancient books as the main treatment for the cold-deficiency of spleen and stomach， and Qi stagnation in children with vomiting and diarrhea and lack of appetite. It has been flexibly applied by later generations of physicians， and is often used to treat anorexia， inflammation of the digestive tract， diarrhea and other diseases in children.
Résumé
By consulting the ancient Chinese herbal books， medical books and formularies of the past dynasties， and combining with modern research data， this paper makes a systematic textual research on the name， origin， place of origin， traditional quality evaluation， harvesting and processing of Selaginellae Herba， so as to provide a basis for the development and utilization of the relevant famous classical formulas. According to the textual research， Juanbai is the correct name of the herbal medicine in all dynasties， and there are also aliases such as Baozu， Qiugu， Jiaoshi and Jiusi Huanhuncao. The origin of Selaginellae Herba in the ancient herbal books was Selaginella tamariscina in all dynasties. Since the Republic of China， S. pulvinata has been gradually used as another origin of Selaginellae Herba. In ancient times， the producing area of S. tamariscina was mainly in Shandong， Hebei， Henan， Shaanxi， Jiangsu and Sichuan， etc. Nowadays， it is produced all over the country. S. pulvinata is mainly produced in Guangxi， Fujian， Sichuan， Guizhou， Yunnan， Hebei and so on. Since the recent times， it is concluded that the quality of the green color， complete and unbroken is good. Before the Qing dynasty， it was recorded that the harvesting time of Selaginellae Herba was generally from April to July， and it was expanded to all year round since the Qing dynasty. After harvesting， remove the sediment（sand and mud）， cut off the fibrous roots and dry in the shade or in the sun. The processing methods in all dynasties were mainly carbonizing by stir-frying and stir-bake to brown， and some ancient books contained the processing method of brine boiling， which was rarely used in modern times. Based on the results， it is recommended that S. tamariscina should be used as the base material of Selaginellae Herba. Because of more impurities， it should be fully purified to ensure the cleanliness of the herb， and the processing method can be based on the prescription requirements， if the processing requirements are not specified， the raw products can be used， charcoal products is recommended for use as an hemostatic.
Résumé
By reviewing the ancient and modern literature， the name， origin， scientific name evolution， place of origin， quality， harvesting， processing， efficacy and toxicity of Asteris Radix et Rhizoma（ARR） were systematically sorted out， so as to provide reference for the development and utilization of the relevant famous classical formulas. According to textual research， ARR was first contained in Shennong Bencaojing， all generations are Ziwan for its proper name， and there are still aliases such as Ziyuan， Ziqian and Xiaobianer. Its mainstream origin in successive generations was Aster tataricus， and there are also Ligularia fischeri and others in local area of use. The medicinal parts of ARR are root and rhizome， but in modern times， the rhizome is mostly used for propagation and cultivation， so some of ARR medicinal materials only have the root without the rhizome. The earliest recorded ancient origin of ARR was now Fangxian（Hubei）， Zhengding and Handan（Heibei）， then the range of production areas gradually expanded， the mainstream production areas from the Song dynasty to the Ming and Qing dynasties included Hebei， Jiangsu， Anhui， Henan and other places， since modern times， two major producing areas have been formed in Anguo， Hebei province and Bozhou， Anhui province. From the quality evaluation， it is clear that from ancient times， flexible roots and purple color are the best. The ancient harvesting was mainly in lunar February or March， and then dried in the shade， and the modern harvesting is mostly in spring and autumn， and the roots are braided into pigtails and then dried in the sun or dried in the sun after 1-2 d. The ancient and modern processing method of ARR are basically the same， mainly honey processing， there are still methods of frying， steaming， vinegar sizzling， etc. Based on the results， it is recommended that the dried roots and rhizomes of A. tataricus should be used in clinical and the development of related famous classical formulas， and those whose original formulas specify the processing requirements can be processed according to the relevant requirements， while whose processing requirements are not specified should be used in the form of raw products.
Résumé
Through consulting the ancient herbal books and modern literature， this paper has carried out the textual research on the name， origin， place of origin， harvesting and processing， and other contents of Bruceae Fructus， combed its ancient and modern medicinal history， so as to provide reference for the development of famous classical formulas containing Bruceae Fructus. Through the herbal textual research， It can be verified that， since the Qing dynasty， Bruceae Fructus has been recorded in the materia medica， most of the materia medica in previous dynasties took Bruceae Fructus as its proper name， and Laoyadan， Kushenzi and Yadanzi as the aliases. The main origin of Bruceae Fructus is Brucea javanica， its medicinal part is the fruit， which is harvested from August to October every year， the fruit can be harvested when it is ripe. Bruceae Fructus was first distributed in Fujian， Guangdong and Guangxi， and gradually expanded to the south of China with the change of time. The traditional processing method of Bruceae Fructus is mainly to remove the shell and kernel， and remove the oil by frosting. The 2020 edition of Chinese Pharmacopoeia stipulates that its processing method is to remove the shell and impurities. Based on the research results， it is suggested that the dried mature fruit of B. javanica should be selected for the development of famous classical formulas containing this herb， and the raw products can be used if the original formula does not specify the processing requirements.
Résumé
By consulting the ancient and modern literature， the textual research of Pharbitidis Semen has been conducted to clarify the name， origin， distribution of production areas， quality specification， harvesting， processing and so on， so as to provide reference for the development and utilization of the relevant famous classical formulas. Through textual research， it can be seen that Pharbitidis Semen was first published in Mingyi Bielu（《名医别录》）， and all dynasties have taken Qianniuzi as the correct name. Based on the original research， the main source of Pharbitidis Semen used in previous dynasties is the dried mature seeds of Pharbitis nil， which is consistent in ancient and modern times. The white Pharbitidis Semen appearing in Compendium of Materia Medica（《本草纲目》） from Ming dynasty is similar to the present P. purpurea. It is produced all over the country， and the quality is better if the particles are full and free of impurities. In ancient times， the harvesting time was mostly in the September. Now it is autumn. The fruits are ripe and harvested， dried to remove impurities for standby. In ancient times， the processing methods of Pharbitidis Semen were mainly wine steaming， steaming and frying until half cooked and grinding the head and end. In modern times， they have been simplified to stir-frying method. The nature， taste， meridian tropism and their effects also change supplements with the deepening of practice. Before the Ming dynasty， they were all bitter， cold and toxic. In the Ming dynasty， there appeared the characteristics of pungent， hot and small poisonous. The efficacy has evolved from controlling low Qi， curing foot edema， removing wind toxin， and facilitating urination to facilitating water and defecation， eliminating phlegm and drinking， and eliminating accumulated insects. The main clinical contraindications are those with weak spleen and kidney， those with weak spleen and stomach， pregnant women， and should not be used with croton and croton cream. Based on the textual research， it is suggested that when developing the classic famous formula with Pharbitidis Semen as the main raw material in the future， it is clear that the source should be the dried mature seeds of Pharbitis nil（black product is its black-brown seeds， white product is its beige seeds）. The processing requirements indicated in the original formula are all processed according to the requirements， and the raw product is recommended to be used as medicine if not specified.

Résumé
This article systematically analyzes the historical evolution of the origin， scientific name， medicinal parts， quality evaluation， harvesting and processing and other aspects of Tsaoko Fructus by consulting ancient materia medica， medical books， prescription books in the past dynasties and combining with the modern literature， so as to provide a basis for the development and utilization of famous classical formulas containing Tsaoko Fructus. According to the research， the name of Caoguo（草果） was first used in the Taiping Huimin Heji Jufang（《太平惠民和剂局方》） in the Northern Song dynasty， Tsaoko Fructus is the correct name of the herbal medicine in all dynasties， and there are also aliases such as Caokou， Doukou， Loukou， Laokou and Caodoukou. The mainstream source of Tsaoko Fructus used in the past dynasties is the dried mature fruit of Amomum tsaoko of Zingiberaceae， but Tsaoko Fructus was often used as a nickname for Amomi Fructus Rotundus or Alpiniae Katsumadai Semen during the Song dynasty. Bencao Pinhui Jingyao（《本草品汇精要》） in the Ming dynasty was the earliest materia medica that recorded Tsaoko Fructus as a separate medicinal herb in sections. Under the influence of early ancient books， there were some books that confused Tsaoko Fructus with other Zingiberaceae plants during the Qing dynasty， it was not until modern times that Tsaoko Fructus was distinguished from other plants. The origin of Tsaoko Fructus is Yunnan and Guangxi， and then gradually expanded to Guizhou and other places. Now Yunnan is the province with the largest planting area of Tsaoko Fructus， and has become the main producing area. Since modern times， it has been recorded in the literature that the quality of Tsaoko Fructus is mainly characterized by large， full， red-brown and strong in smell. According to ancient records， the harvest time of Tsaoko Fructus was in the eighth month of the lunar calendar， and they were mostly used for peeling or simmering. Currently， the harvest period of Tsaoko Fructus is October to November， and then sun-dried or dried after harvesting. The records of the properties and functional indications of Tsaoko Fructus are basically consistent with the ancient and modern documents， which is warm in nature， pungent in flavor， belonging to the spleen and stomach meridians， moderate in dryness and dampness， intercepting malaria and eliminating phlegm， used for internal resistance of cold and dampness， abdominal distension and pain， fullness and vomiting， malaria cold and fever， and plague fever. Based on the research results， it is suggested that A. tsaoko should be used as the medicinal base for the development of famous classical formulas containing Tsaoko Fructus， processing method can be according to the requirements of the prescription， and if the requirements of concoction are not indicated， it can be used in the form of raw products.
Résumé
In order to provide basic information for the utilization and development of famous classical formulas containing Bletillae Rhizoma， this article systematically analyzes the historical evolution of the name， origin， harvesting and processing of Bletillae Rhizoma by reviewing the ancient materia medica， prescription books， medical books and modern literature. The research results showed that Baiji（白及） was the main name， some scholars took Baiji（白芨） as its main name， and there were many other names such as Baiji（白给）， Baigen（白根）， Baiji（白苙）. The mainstream source of Bletillae Rhizoma was the tubers of Bletilla striata， and drying， large， white， solid， root-free and skin removed completely were the good quality standards. With the promotion of wild to cultivated medicinal materials， there were certain differences between their traits， and the quality evaluation indexes should be adjusted accordingly. The origin of records in the past dynasties was widely distributed， with Guizhou and Sichuan having high production and good quality in modern times. The harvesting period is mostly in spring and autumn， and harvested in autumn was better. The processing and processing technology is relatively simple， and it was used fresh or powdered in past dynasties， while it is mainly sliced for raw use in modern times. Based on the results， it is suggested that the tubers of Bletilla striata of Orchidaceae should be used in the famous classical formulas， and it should be uniformly written as Baiji（白及）. And if the original formula indicates the requirement of processing， it should be operated according to the requirement， if the requirement of processing is not indicated， it can be used in raw form as medicine.
Résumé
By consulting ancient and modern literature， the herbal textual research of Farfarae Flos has been conducted to verify the name， origin， producing area， quality evaluation， harvesting and processing methods， so as to provide reference for the development and utilization of the famous classical formulas containing Farfarae Flos. According to the research， the results showed that Farfarae Flos was first described as a medicinal material by the name of Kuandonghua in Shennong Bencaojing（《神农本草经》）， and the name was used and justified by later generations. The main origin was the folwer buds of Tussilago farfara， in addition， the flower buds of Petasites japonicus were used as medicine in ancient times. The ancient harvesting time of Farfarae Flos was mostly in the twelfth month of the lunar calendar， and the modern harvesting time is in December or before the ground freeze when the flower buds have not been excavated. Hebei， Gansu， Shaanxi are the authentic producing areas with the good quality products. Since modern times， its quality is summarized as big， fat， purple-red color， no pedicel is better. Processing method from soaking with licorice water in the Northern and Southern dynasties to stir-frying with honey water followed by micro-fire in the Ming dynasty， and gradually evolved to the modern mainstream processing method of honey processing. Based on the research results， it is suggested that the dried flower buds of T. farfara， a Compositae plant， should be selected for the development of famous classical formulas containing Farfarae Flos， and the corresponding processed products should be selected according to the specific processing requirements of the formulas， and raw products are recommended for medicinal use without indicating processing requirements.
Résumé
By consulting the ancient and moderm literature， this paper makes a textual research on the name， origin， quality evaluation， harvesting and processing of Olibanum， so as to provide a basis for the development of the famous classical formulas containing this medicinal material. According to the herbal textual research， the results showed that Olibanum was first described as a medicinal material by the name of Xunluxiang in Mingyi Bielu（《名医别录》）， until Ruxiang had been used as the correct name since Bencao Shiyi（《本草拾遗》） in Tang dynasty. The main origin was Boswellia carterii from Burseraceae family. The mainly producing areas in ancient description were ancient India and Arabia， while the modern producing areas are Somalia， Ethiopia and the southern Arabian Peninsula. The medicinal part of Olibanum in ancient and modern times is the resin exuded from the bark， which has been mainly harvested in spring and summer. It is concluded that the better Olibanum has light yellow， granular， translucent， no impurities such as sand and bark， sticky powder and aromatic smell. There were many processing methods in ancient times， including cleansing（water flying， removing impurities）， grinding（wine grinding， rush grinding）， frying（stir-frying， rush frying， wine frying）， degreasing， vinegar processing， decoction. In modern times， the main processing methods are simplified to cleansing， stir-frying and vinegar processing. Nowadays， the commonly used specifications include raw， fried and vinegar-processed products. Among the three specifications， raw products is the Olibanum after cleansing， fried products is a kind of Olibanum processed by frying method， vinegar-processed products is the processed products of pure frankincense mixed with vinegar. Based on the research results， it is recommended to select the resin exuded from the bark of B. carterii for the famous classical formulas such as Juanbitang containing Olibanum， processing method should be carried out in accordance with the processing requirements of the formulas， otherwise used the raw products if the formulas without clear processing requirements.
Résumé
Danggui Sinitang is first recorded in the Treatise on Cold Damage written by ZHANG Zhongjing in the Han dynasty. It is composed of Angelicae Sinensis Radix， Cinnamomi Ramulus， Paeoniae Radix Alba， Asari Radix et Rhizoma， Glycyrrhizae Radix et Rhizoma， Tetrapanacis Medulla， and Jujubae Fructus and serves as a classic formula for treating the syndrome of blood deficiency and cold reversal. This study systematically reviews the records of Danggui Sinitang in ancient Chinese medicine books of various dynasties and the modern clinical applications to probe into the composition， plant species， processing， dosage， decocting method， and indications of Danggui Sinitang， aiming to provide a reference for the development and clinical application of this classic formula. The review of the records showed that there were a variety of records of Danggui Sinitang with different composition， and the composition of this formula listed in the Treatise on Cold Damage has a significant impact on later generations and has been used by medical practitioners throughout history. Although the dosage of some drugs decreased during the Ming and Qing dynasties， the medical practitioners continued to use the original formula. In terms of processing， although there were slight changes in the processing of Angelicae Sinensis Radix， Paeoniae Radix Alba， Glycyrrhizae Radix et Rhizoma， and Tetrapanacis Medulla， the original processing method was inherited. In terms of indications， Danggui Sinitang was designed to treat cold reversal due to blood deficiency and dysentery. Furthermore， it was used to treat headache， convulsive disease， infantile convulsion， and private part adduction in the Ming and Qing dynasties. Nowadays， this formula is mostly used to treat diabetes peripheral neuropathy， rheumatoid arthritis， dysmenorrhea， Raynaud's disease and other diseases. In terms of precautions， ancient physicians believed that Danggui Sinitang should not be taken by pregnant women and should only be used for limb chills caused by blood deficiency and cold coagulation. For limb chills caused by other reasons， this formula should not be used indiscriminately. Modern research has not reported any serious adverse reactions related to this formula. Danggui Sinitang has a definite therapeutic effect. In subsequent research and development， quality control standards of Danggui Sinitang should be established while its safety is ensured， and the related preparations should be developed and applied.

Résumé
In this paper， the name， origin， quality evaluation， producing area and processing methods of Lablab Semen Album in the famous classical formulas were researched by reviewing the ancient materia medica， medical books， prescription books and modern literature. The results showed that the name of Lablab Semen Album in the past dynasties was mostly derived from its shape and color， called Biandou and Baibiandou. The mainstream origin used in the past dynasties was Lablab purpureus， the medicinal parts were mainly white mature seeds， with the addition of the leaves in the Song dynasty and the flowers in the Ming dynasty. Since modern times， the authentic producing areas of Lablab Semen Album are Suzhou， Zhejiang and other places， and now mainly produced in Chuxiong and Xinping， Yunnan and Panzhihua， Sichuan. The traditional quality evaluation of Lablab Semen Album is evaluated as large， solid， full and white. The harvesting time of this herb is recorded from the eighth to the ninth lunar month in related literature， the pods are picked when the seeds are ripe， and the seeds are dried in the sun. In ancient times， the processing of Lablab Semen Album mainly consisted of frying the seeds with skin and then pulverizing for use， or soaking and peeling seeds for raw use. Based on the conclusion of the textual research， it is recommended that the seeds or flowers of the white flowering plants of L. purpureus， a member of the leguminosae， should be used in the famous classical formulas， and the dried seeds or dried flowers of Lablab Semen Album can be used as medicine if the formula did not clearly indicate processing requirements.
Résumé
By reviewing ancient materia medica， medical and prescription books， combined with modern literature， the textual research of Stephaniae Tetrandrae Radix has been conducted to verify the name， origin， producing area， harvesting and processing methods. Through textual research， the results show that the mainstream name of this herb recorded in the past dynasties is Fangji， which is also called Hanzhong Fangji because it is produced in Hanzhong city， and after the Tang dynasty， it was gradually divided into Hanfangji and Mufangji， and there is the saying that Han Zhushuiqi， Mu Zhufengqi. The names of Fenfangji and Guangfangji were first seen in the republic of China. In addition， Fenfangji was once distributed in Hankou， so it was also known as "Hanfangji"， which is easily confused with the traditional Hanzhong Fangji for short. Based on the original research， it is concluded that Aristolochia heterophylla（Hanzhong Fangji）is the mainstream of Stephaniae Tetrandrae Radix used in the Qing dynasty and before， and the application history of Cocculus orbiculatus can be traced back to before the Tang dynasty. After the Ming dynasty， Stephania tetrandra gradually became another main origin， and in the Republic of China， A. fangchi was used as a medicine for Stephaniae Tetrandrae Radix， but in modern times it was banned because it contained aristolochic acid as a toxic ingredient， and S. tetrandra has become the mainstream legal origin. The traditional production area of Hanzhong Fangji is Hanzhong， Shaanxi province， while today the mainstream of S. tetrandra is manly produced in Jiangxi and other places. Based on the quality evaluation research， the quality of Hanzhong Fangji is better with the radial texture of section used as radial solution， yellow solid and fragrant. Fenfangji with solid quality， white inside， powdered enough， less fiber and radiating texture is better. From the harvesting and processing research， the root of Fangji is mostly harvested in spring and autumn， and the outer bark should be removed in some literature. Before the Ming dynasty， this herb was dried in the shade， and after the Ming dynasty， it was dried in the sun. The modern production processing of Fangji is to harvest it in autumn， wash it， remove the rough bark， dry it to half dry， cut it into sections， and then cut it longitudinally if it is large， and dry it. Based on the results， combined with current studies on the toxicity of aristolochic acid and influencing factors such as commercial circulation， it is suggested that S. tetrandra should be used as the origin of Fangji， the processed products are selected according to the prescription requirements， and those without specified requirements can be processed by referring to the raw products in the 2020 edition of Chinese Pharmacopoeia.
Résumé
Through consulting the ancient materia medica and medical books， combined with modern literature， this paper made a textual research on the name， origin， producing area， harvesting time and processing method of Piperis Kadsurae Caulis， in order to provide basis for the development of the famous classical formulas containing this herb. According to textual research， it is shown that the earliest name for Piperis Kadsurae Caulis as medicine was Nanteng in Bencao Shiyi， and there were other names such as Dinggongteng and Shinanteng in the ancient materia medica. The name of Haifengteng should appear in the Ming dynasty. Before the Song dynasty， the origin of Piperis Kadsurae Caulis was probably derived from caulis of Piper wallichii. After the Song dynasty， the main origins should be some species in Piper， such as P. kadsura and P. hancei， and its origin in the successive editions of Chinese Pharmacopoeia was only P. kadsura. Combining the original plant research， market survey and distribution of wild resources， it is suggested that the Haifengteng used in the famous classical formulas apart form the P. kadsura， the P. hancei should be add as original plant. Due to climate change and the heat-loving habit of Piper， the producing area of Haifengteng gradually moved from the Qinling Mountains to the southern areas rich in Piper， and Quanzhou area of Fujian province has been recommended since the Ming dynasty. The harvesting period of Piperis Kadsurae Caulis is from July to August in the lunar calendar， the above-ground parts are dried by removing fibrous roots， thin stems and leaves. In the past dynasties， there are few records on the processing of this herb， so it is suggested that Piperis Kadsurae Caulis in famous classical formulas without special processing requirements should be used as raw products.
Résumé
By reviewing ancient materia medica and combining with modern literature， the textual research of Magnoliae Flos has been conducted to verify the name， origin， producing area， harvesting and processing methods， in order to provide basis for the selection and use of this herb in the development of famous classical formulas. After the textual research， it could be seen that the correct name of Magnoliae Flos was Xinyi in the past dynasties， meaning spicy flower buds. The main original plants used in past dynasties are Magnolia denudata and M. biondii. The history of the research on its scientific name in recent times is complicated， many foreign scholars have given several different scientific names， but most of them are inconsistent with the actual situation of Magnoliae Flos used in ancient China， because foreign scholars failed to collect the original plants of Magnoliae Flos for accurate identification. Before the Ming dynasty， Magnoliae Flos was mainly produced in Shaanxi， and then the recorded production areas gradually increased. After the founding of the People's Republic of China， the products produced in Henan named M. biondii were highly respected， and Henan was regarded as authentic producing area， and because of the collection and distribution through Yuzhou， it was customarily called Huichunhua. In ancient times， the harvesting period of Magnoliae Flos mostly concentrated in the first and second months of the lunar calendar， and the flower buds of M. biondii were also recommended to be used as medicine， but nowadays the flower buds are mostly collected in winter and spring， and those with dry buds， large size， yellow-green color， tight inner petals， fragrant smell， and no impurities are preferred. In the past dynasties， raw products were the mainstream， and there were also frying， soaking and so on. Based on the results， it is suggested that the flower buds of M. biondii should be used in the development of famous classical formulas. If the original formula does not specify the processing requirements， the raw products can be used as medicine.
Résumé
By reviewing the materia medica， medical books and scripture history， combining modern and contemporary literature and field investigation， this paper systematically reviewed the name， origin， scientific name， producing area， quality， harvesting and processing of Scorpio in famous classical formulas to clarify the relationship between ancient and modern times and provide a reference basis for the development of related famous classical formulas. After the textual research， it can be seen that there are many names of Scorpio， and most of the materia medica use Xie or Quanxie as the official name. The origin of Scorpio used in the past dynasties is Buthus martensii， which is the same in ancient and modern times. B. martensii is mainly distributed in the central and eastern parts of China， as well as Mongolia， Korea and other places， located in East Asia. Therefore， pharmaceutical workers in China mostly continue to use the early Chinese name， that is， Dongya Qianxie， while modern Scorpiones taxonomists set its Chinese name as Mashi Zhengqianxie. In order to maintain the stability and continuity of the origin of Scorpio， the previous editions of Chinese Pharmacopoeia have always used the name of B. martensii. The geo-authentic producing area of Scorpio， which has been respected in the past dynasties， was Qingzhou， Shandong. Until the Republic of China， due to the different processing methods in the production area， the geo-authentic producing area expanded to Yu county， Henan， with Yu county as the distribution center， the best quality of Scorpio is produced by boiling in clear water and drying after boiling. The origin processing of Scorpio is mainly divided into clean water and salt water boiling and then drying， where the method of boiling with salt water was first described in Bencao Yuanshi， the purpose is antiseptic and suitable for storage， and the salt should be washed away when used clinically. There are few processing methods of Scorpio， in ancient times， it was used for roasting or frying after removing the feet， in modern times， it is mostly to remove impurities， wash and dry. Scorpio is not only used for medicinal purposes， but also has the habit of eating in many areas， so the consumption of resources is relatively large， and it is still mainly harvested from the wild， resulting in the decrease of wild resources year by year. Based on the research conclusion， it is recommended that B. martensii， which is produced in Qingzhou， Luyi or Yuzhou， should be used in the the development of famous classical formulas containing Scorpio， and the origin processing is preferable to be dried after boiling with water， and the processing specification should be selected as raw products. And B. martensii in geo-authentic producing areas was used as the seed source to establish a standardized breeding base to ensure the sustainable development of the resources of Scorpio.
