A systematic methodology to assess the identity of plants in historical texts: A case study based on the Byzantine pharmacy text John the Physician's Therapeutics.

ETHNOPHARMACOLOGICAL RELEVANCE: In recent decades, the study of historical texts has attracted research interest, particularly in ethnopharmacology. All studies of the materia medica cited in ancient and medieval texts share a concern, however, as to the reliability of modern identifications of these substances. Previous studies of European or Mediterranean texts relied mostly on authoritative dictionaries or glossaries providing botanical identities for the historical plant names in question. Several identities they suggest, however, are questionable and real possibility of error exists. AIM OF THE STUDY: This study aims to develop and document a novel and interdisciplinary methodology providing more objective assessment of the identity of the plants (and minerals) described in these resources. MATERIALS AND METHODS: We developed an iterative experimental approach, using the 13th century Byzantine recipe text John the Physician's Therapeutics in its Commentary version (JC) as a case study. The methodology has six stages and relies on comparative analyses including statistical evaluation of botanical descriptions and information about medicinal uses drawn from both historical and modern sources. Stages 1-4 create the dataset, stage 5 derives the primary outcomes to be reviewed by experts in stage 6. RESULTS: Using Disocorides' De Materia Medica (DMM) (1st century CE) as the culturally related reference text for the botanical descriptions of the plants cited in JC, allowed us to link the 194 plants used medicinally in JC with 252 plants cited in DMM. Our test sample for subsequent analyses consisted of the 50 JC plant names (corresponding to 61 DMM plants) for which DMM holds rich morphological information, and the 130 candidate species which have been suggested in the literature as potential botanical identities of those 50 JC plant names. Statistical evaluation of the comparative analyses revealed that in the majority of the cases, our method detected the candidate species having a higher likelihood of being the correct attribution from among the pool of suggested candidates. Final assessment and revision provided a list of the challenges associated with applying our methodology more widely and recommendations on how to address these issues. CONCLUSIONS: We offer this multidisciplinary approach to more evidence-based assessment of the identity of plants in historical texts providing a measure of confidence for each suggested identity. Despite the experimental nature of our methodology and its limitations, its application allowed us to draw conclusions about the validity of suggested candidate plants as well as to distinguish between alternative candidates of the same historical plant name. Fully documenting the methodology facilitates its application to historical texts of any kind of cultural or linguistic background.

"From the Known to the Unknown:" Nature's Diversity, Materia Medica, and Analogy in 18th Century Botany, Through the Work of Tournefort, the Jussieu Brothers, and Linnaeus.

The growth of botany following European expansion and the consequent increase of plants necessitated significant development in classification methodology, during the key decades spanning the late 17th to the mid-18th century, leading to the emergence of a "natural method." Much of this development was driven by the need to accurately identify medicinal plants, and was founded on the principle of analogy, used particularly in relation to properties. Analogical reasoning established correlations (affinities) between plants, moreover between their external and internal characteristics (here, medicinal properties). The diversity of plants, names, and botanical information gathered worldwide amplified confusion. This triggered the systematisation of the collection and referencing of data, prioritizing the meticulous observation of plant characteristics and the recording of medicinal properties as established by tradition: it resulted in principled methods of natural classification and nomenclature, represented by the genus, to enhance reliability of plant knowledge, which was crucial in medical contexts. The scope of botany increased dramatically, with new methods broadening studies beyond traditional medicinal plants. The failure of chemical methods to predict properties, particularly of unknown flora, amplified the reliance on analogy and on natural affinities.

How Did the Clinical Medicine Progress during the Unified Silla Era: Installment of the Medical Education Center 'Uihak', and Its Effects.

In this research, I aimed to recognize the historical meaning of installing the medical education center, 'Uihak', during the Silla dynasty. 'Uihak' was installed in 692, in the first year of King Hyoso 's rule. 'Uihak' was founded by using various Chinese medical classics as its textbooks for medical education, such as the Classic of Plain Questions. The wooden prescriptions excavated from Anapji, which is thought to have been created in the middle of the 8th century, and the Chinese medical book Prescriptions for Universal Benefit, which the envoy of Silla tried to acquire in 803, reflect the idea on medicine during that period in Silla. By this time, the field of medicine began to develop the idea to discern the locations and mechanism of disease patterns by centering on the viscera and bowels while making use of the herbal prescriptions based on various drugs. This means that clinical medicine founded upon the medical education achieved in 'Uihak' was being realized in the medical fields as well. According to the Chronicles of the Three States, for the illness of Queen Sunduk in 636, medicine, praying, and the method of esoteric Buddhism was tried out as a means of her cure. Comparatively, for the treatment of the first rank Chunggong in 822, the Kingdom's representative doctor with professional medical knowledge was sought out to fine a cure. The analyses of the human disease, diagnosis, treatment method, etc., given by the kingdom's representative doctor were identical to those recommended in the medical textbooks used in 'Uihak'. As such, we can posit that his academic background was 'Uihak' and the education given there. The Classic of Materia Medica, which was also used in 'Uihak', was a book professionally centered on the drug branch of medicine. The Classic of Materia Medica is a terminology referring to various books on drugs, including the Shennong's Classic of Materia Medica, the Variorum of the Classic of Materia Medica, the Newly Revised Materia Medica, etc. Thus, we cannot specify what the classic of Materia Medica actually taught, based on only its terminology. However, based on the wooden prescriptions excavated from Anapji, and from the terminology of drugs recorded in the drug trading document Purchase List for Silla goods preserved in Shosoin of Japan, we can hypothesize that in the middle of the 8th century, the Newly Revised Materia Medica was indeed being circulated. Based on these evidences, we can also hypothesize that Silla was part of the network of drug trading that encompassed the entire region of Asia. After unifying the Korean peninsula, the Kingdom of Silla actively adopted the medical educational system of Tang China. By using the obtained medical knowledge, Silla cured illnesses and used the medical knowledge on various drugs recorded in the Newly Revised Materia Medica to pursue trade with China, Japan, and other countries. Through the installation of 'Uihak', the same medicine has now begun to be officially used in East Asia, including Silla.

Overview of Dioscorides' recipes in Croatian books of folk recipes.

The aim of this paper is to present an overview of Dioscorides' recipes from his work De materia medica which are found in Croatian folk medicine preserved in books of folk recipes called ljekaruse. The particularities of five published and analysed Croatian books of folk recipes from the 17 th and 18 th century are examined. Recipes with drugs of herbal and animal origin, which are most often mentioned in Croatian books of folk recipes, and which were available in folk medicine at the time, are compared with those from Dioscorides' work. Many herbal drugs described in books of folk recipes are today used in contemporary phytotherapy, and modern biomedical research reveals new bioactive substances and confirms new and potential biological activities in medicinal plants used in folk medicine, which is the basis for further study of De materia medica by Dioscorides and ethnomedicinal collections. Croatian books of folk recipes are a valuable resource for multidisciplinary study, including for medicinal and pharmaceutical historians, philologists and ethnologists.

[P.F. von Siebold and his destiny with Chinese materia medica (Ben Cao)].

P. F. von Siebold (1796-1866) was a physician at the Dutch Business Centre (Shang Wu Hui Guan) located at Nagasaki, Japan, in the Edo period. He collected a great amount of botanical and mineral specimens, books, and living wares when he stayed in Japan. He brought these materials to Europe and kept some of them at the Japan Museum Siebold Huis in Leiden in Netherlands. This collection showed the role of Siebold in connecting scientific and cultural exchanges between East and West and provided references in the research of the transmission of traditional Chinese medicine worldwide in the 19th century.

[Textual research on varieties of Draconis Sanguis].

This paper reviewed the historical evolution of the varieties of Draconis Sanguis in traditional Chinese medicine(TCM) and discussed several doubts. Draconis Sanguis used in ancient Europe and Arabia was derived from Dracaena plants, and that originating from Southeast Asia entered the market in the 16 th century. Draconis Sanguis was introduced into China in the 5 th century at the latest and was once mixed with shellac for use. Draconis Sanguis in the Tang Dynasty and before was the resin of Dracaena plants. Scholars in the Song Dynasty have known that Draconis Sanguis came from the resin of tall trees, but their understanding of origin plants was inconsistent with the facts. The origin of Draconis Sanguis in the Song Dynasty was basically determined to be Mirbat(Maliba), Cengtan, and Somali, as well as Socotra Archipelago. About 1371-1416, Draconis Sanguis prepared from Daemonorops draco was imported into China, and was recorded earlier in The Overall Survey of the Ocean's Shores(Ying Ya Sheng Lan) and Code of Great Ming Dynasty(Da Ming Hui Dian). Draconis Sanguis prepared from Dracaena plants was still authentic for a long time after the import of that from D. draco into China. During the Ming and Qing Dynasties, Dian Zhi(1625), a lost edition of Materia Medica in Southern Yunnan(Dian Nan Ben Cao), Textual Research on Reality and Titles of Plants(Zhi Wu Ming Shi Tu Kao), and other local chronicles recorded that a new type of Draconis Sanguis(Mu Xue Jie) was produced in Yuanjiang, Yunnan province. The New Yunnan Chronicles of the Republic of China recorded the production of another type of Draconis Sanguis(Qi Lin Jie) in Xishuangbanna. However, the authenticity of the above two types has been difficult to confirm. In modern times, Draconis Sanguis prepared from D. draco gradually became the mainstream variety. In the 1970 s, Dracaena cochinchinensi was found in Yunnan and other provinces, and Draconis Sanguis from D. cochinchinensi was developed. This study is expected to provide a solid and reliable literature support for the research and development of Draconis Sanguis, enrich historical materials, and provide new clues for follow-up research.

Antimonium Tartaricum as a Possible Homeopathic Prophylactic Remedy in the COVID-19 Epidemic.

The current COVID-19 (coronavirus disease 2019) epidemic has proved challenging due to its high impact on physical and mental health. According to Hahnemann, the founder of homeopathy, in an epidemic the most severe symptoms of the clinical condition presented by the population in question should be the basis for selecting the medication that is as similar as possible to them, and which should be administered to individuals who have been exposed to the disease but have not yet developed it. This medicine is called the genus epidemicus. This study aims to demonstrate the reasoning used to propose the homeopathic medicine Antimonium tartaricum (Ant-t) as a genus epidemicus in the COVID-19 epidemic. It was decided to develop the reasoning based on the respiratory symptoms described in the epidemiological bulletins presented by the Health Surveillance Secretariat of the Ministry of Health of Brazil, as these symptoms are the most serious of the disease. After repertorization, it was confirmed in the Materia Medica that Ant-t has a high degree of similarity with these respiratory symptoms, including the most serious situations, of COVID-19. Homeopathic Ant-t is thus a possible prophylactic genus epidemicus in the COVID-19 epidemic; further studies are needed to test this conclusion.

An investigation of the pharmacological applications used for the Ancient Egyptian systemic model 'ra-ib' compared with modern Traditional Chinese Medicine.

ETHNOPHARMACOLOGICAL RELEVANCE: Ancient Egyptian texts only offer glimpses into their conceptual understandings of the inner-body and illness manifestation. Explanations of how prescribed materia medica were believed to work are rare and obscure, often resulting in modern approximations for ancient terminology such as 'ra-ib'-an ancient Egyptian classification predominantly translated as 'stomach'-leading to misunderstandings of historical texts, and therefore their use of pharmacology. AIM OF THE STUDY: To investigate the ra-ib and the explanatory models of illness from the Egyptian perspective, and to explore the link between these and the prescribed selection of materia medica. To then compare the conceptual mechanics of these treatment strategies with those of another non-Western tradition-namely Traditional Chinese Medicine (TCM)-to provide further insight into potential conceptual frameworks. MATERIALS AND METHODS: We conducted a case study of a unit of Ancient Egyptian texts focusing on the ra-ib. Totalling 34 prescriptions, the first stage lexicographically analysed the texts using cognitive linguistic and translation theories to produce our new understanding. This enabled our comparison of the mechanics of materia medica usage within these texts with those found in TCM outlined by the Pharmacopoeia of the Peoples Republic of Pharmacopeia of the People's Republic of China 2015 for the relevant ingredients. RESULTS: the study demonstrated that-rather than denoting the organ 'stomach'-ra-ib instead constitutes a system running from the mouth, downward to the anus. This is best translated as 'inner thoroughfare', and changes the way in which we attempt to understand potential motivations in the selection of ingredients. By exploring common themes in the use of eleven securely translated ingredients from the Egyptian corpus and the Pharmacopoeia of the People's Republic of China-representing a modern traditional system which understands the body via a series of interconnected systems-we were able to highlight certain themes which might be 'universal' to system-based traditions; this provided new insights into the Egyptian motivations for treatment selection. CONCLUSIONS: Having gained the ancient view of the body and illness, cultural comparisons are important for providing further potential insights and clarifications of a discontinued historical healing tradition. The new understanding of the ra-ib from our study greatly changes the way in which we understand the dynamics of Egyptian ethnopharmacological source material from this period.

Analysis of historical changes in traditional Chinese medicine based on an Indonesian collection of Chinese materia medica from c. 1870.

ETHNOPHARMACOLOGICAL RELEVANCE: Traditional Chinese Medicine is subject to changes over time: product names, botanical ingredients, processing methods and uses have varied throughout the course of history. Historic collections of Chinese materia medica (CMM) are of great value for research on the evolvement, development and variability of Chinese herbal medicine over time. These changes may have a significant influence on the safety and efficiency of nowadays' clinical practice. Here we investigate a historic collection of Chinese medicinal products purchased in Indonesia in c. 1870, containing about 395 specimens. AIM OF THE STUDY: This study compares the specimens contained in late 19th century collection of CMM with contemporary marketed materials by investigating changes in vernacular names, botanical identity and processing methods which are important aspects for safety and clinical practice today. MATERIALS AND METHODS: The contents and associated documentation of the CMM collection of Dr. C.H.A. Westhoff (University Museum Utrecht) were revised by means of morphological identification and study of the associated historic documentation. We compared this Westhoff collection with contemporary CMM, information from literature and various quality standards, including the official Chinese pharmacopoeia. RESULTS: The Westhoff collection represents a unique, well preserved collection of Chinese materia medica, with original uniform bottles, Chinese labels and a partly intact handwritten catalogue. Among the 395 specimens (bottles) of CMM surveyed, there are 387 contain a single component drug, while eight contain multiple components drugs. A total of 293 of the 395 specimens are mentioned in the modern Chinese pharmacopoeia. Ca. 25% of the specimens had been processed, such as stir-fried with or without adjuvants. Our analysis of local Chinese names, botanical content and processing methods indicate that this collection originates from southern part of China, possibly including in the region of Taiwan and was meant as a showcase for pharmaceutical education and/or as curiosity object. CONCLUSION: Differences in vernacular names, plant parts and processing methods between the Westhoff collection and the current Chinese pharmacopoeia illustrate the regional variety of CMM and changes in CMM in the course of time. This work contributes to the understanding of the evolvement of CMM from a historic perspective.

Nineteenth-Century Homeopathic Repertories Predict Increased Urinary Excretion of Bile in Cholestasis but Not in Non-Cholestatic Infant Jaundice.

INTRODUCTION: There are two types of bilirubin: conjugated bilirubin, prevalent in cholestatic jaundice, and unconjugated bilirubin, prevalent in hematologic jaundice. Conjugated bilirubin is water soluble and is excreted in urine, whereas unconjugated bilirubin is neither water soluble nor excreted in urine. Homeopathic repertories published prior to the discovery of the two types of bilirubin in 1913 present an opportunity to test the reliability of homeopathic repertories and associated materia medica. If procedures involved in the collecting of homeopathic observations are reliable, then in repertories published prior to 1913, medicines listed for cholestatic jaundice should exhibit a stronger association with urine bile than medicines listed for hematologic jaundice. MATERIALS AND METHODS: In three repertories published prior to 1913, medicines associated with jaundice were further classified into groups labeled "Cholestatic" or "Infant, mostly hematologic". Medicines were identified as "Cholestatic" if associated with both white/clay-colored stool and liver/gallbladder symptoms. Medicines were identified as "Infant, mostly hematologic" if associated with infant jaundice without meeting criteria for the "Cholestatic" group. Controls were medicines appearing in Hahnemann's Materia Medica Pura. Each category was assessed for green urine-usually reflective of bile in urine. RESULTS: In Knerr's repertory, the "Cholestatic" group demonstrated a significantly greater association with green urine than controls (p < 0.05, Fisher's exact test), whereas the "Infant, mostly hematologic" group did not differ significantly from controls. For Lippe's and Boenninghausen's repertories, statistical significance was not demonstrated. Across repertories, the overall weighted pooled odds ratio (OR) demonstrated significance in the association between the "Cholestatic" group and green urine (OR, 2.384; 95% confidence interval, 1.234 to 4.607), whereas the "Infant, mostly hematologic" group was similar to that of controls (OR, 0.754; 95% confidence interval, 0.226 to 2.514). CONCLUSIONS: Based on the presence or absence of bile in the urine, homeopathic repertories from the 19th century can distinguish between disease processes involving conjugated bilirubin and disease processes involving unconjugated bilirubin.

Bodies of the plant and Animal Kingdom: An illustrated manuscript on materia medica in the Netherlands (ca. 1800).

ETHNOPHARMACOLOGICAL RELEVANCE: Around 1800, Amsterdam was a global trade hub for materia medica of Dutch, European and exotic origin. Contemporary knowledge on medicinal plants in academic circles has been well documented in local pharmacopoeia, illustrated herbals and catalogues of botanic gardens. Until the end of the ancient regime, physicians, surgeons and apothecaries were trained how to use plants in their specific guild or Collegium Medicum. Little is known, however, on how the plant collectors and merchants that provided the pharmaceutical substances to apothecaries learnt to recognise the variety of medicinal products. AIM OF THE STUDY: To analyse the content, origin, purpose and scientific importance of an anonymous, undated, hand-written Dutch manuscript on materia medica, entitled Corpora ex Regno Vegetabili/Animali (Bodies of the Plant/Animal kingdom) kept by the Artis Library of the University of Amsterdam, the Netherlands. MATERIALS AND METHODS: We digitised the entire manuscript and dated the paper by means of its watermark. We identified the plant and animal species using the historic Dutch and Latin names, the illustrations and historic literature. We compared the plant properties and uses to contemporary literature to check whether the information in the manuscript was original or copied from another source. RESULTS: The paper was produced between 1759 and 1816 in Zaandam, the Netherlands. The manuscript contains 19 substances of animal origin, one mineral and 273 plants and plant-derived products, which belong to ca. 260 species. While most plants are native or cultivated in the Netherlands, 111 plant entries (105 spp.) represent exotic products, imported from as far as Madagascar and Australia. A total of 134 illustrations were cut out from a 1549 Dutch edition of the New Herbal by Leonhard Fuchs (1543), but only 69% correspond to the correct species. The manuscript contains detailed descriptions on growth locations, field characteristics, flowering season, provenance and quality of the medicinal products, including methods to detect forgery. The author mostly described humoral properties of the plants rather than listing medicinal recipes. We did not find evidence that he copied his texts from other sources, but the Dutch and Latin names correspond largely with the Amsterdam pharmacopoeia from 1795. CONCLUSIONS: The author's extensive knowledge on trade names, quality and origin of materia medica and his refrain from using literature suggests he could have been a merchant, an intermediary between herb cultivators, overseas traders and apothecaries. This manuscript offers a unique insight in the global trade in medicinal products and the circulation of knowledge in non-academic circles around 1800.

Accuracy of Dioscorides,' De materia medica (First Century C.E.), Regarding Diuretic Activity of Plants.

OBJECTIVES: Assess whether an ancient text on herbal medicine accurately characterizes a class of herbal diuretics. DESIGN: The Greek text of Dioscorides De materia medica was assessed for herbs stated to have diuretic activity, and then modern research was sought to determine how accurate the ancient assessment of these herbs was. RESULTS: Of the 105 plants cited as having diuretic activity by Dioscorides, 56 (53.3%) genuses are confirmed as being diuretic in animal or human research. For another 38 (36.2%) genuses, no research related to diuresis could be identified. Six (5.7%) genuses had mixed results in modern research, whereas a mere 5 (4.8%) genuses were shown to not have diuretic activity. Considering the 67 genuses that were investigated, 56 (83.6%) were confirmed. CONCLUSION: This analysis confirms that Dioscorides was accurate in determining the diuretic nature of herbs, raising the possibility that he was right about other therapeutic suggestions concerning herbs he made. For the remaining herbs that have not been assessed for diuretic effect, it is not yet known if Dioscorides was accurate. Our findings suggest that the 38 herbs Dioscorides categorized as diuretics that have not been studied for diuretic function are candidates for research in this regard.

[A study of the Polish missionary Michel Boym's pharmacy books].

Michel Boym was a 17th-century missionary who came to China from Poland. He was the first man who introduce Chinese herbal medicine to Europe by writing Flora Sinensis (Chinese Flora) and Medicamenta Simplicia quae Chinensibus ad usum medicum adhibentur. This article reveals that which Chinese herbal medicine books may have been consulted in the Medicamenta Simplicia quae Chinensibus ad usum medicum adhibentur by analyzing its content and comparing it with the Chinese herbal medicine books. We believed that in order to write this book, he consulted many Chinese books, collected a variety of herbal samples and consulted Chinese people who knew about herbals, and added his own understanding. As a western pharmacology book, his book structure, content and characteristics are the closest to Chinese herbal medicine books. And which Chinese books he has consulted, may include, but is not limited to BenCao GangMu(Compendium of Materia Medica)《》, Lei Gong Pao Zhi Yao Xing Jie 《》, Ben Cao Meng Quan《》 and Xin Kan Lei Gong Pao Zhi Bian Lan 《》.

[Exploration on an overview of history (from Chunqiu to Ming and Qing Dynasties) and species of Chinese exotic traditional medicine].

This paper collected and analyzed literatures about starting of traditional medicine and trading of different medicine from Chunqiu Zhanguo to Ming and Qing Dynasties, in order to preliminarily explore on an overview of specie of chinese exotic traditional medicine and trade of different country in different dynasty（from Chunqiu to Ming and Qing Dynasties）, as well as the amount of exotic medicine over two thousand years. (remove repeating and doubtful species), find peculiarity of exotic medicine, sreen species that used to develop the Silk Route and establish quality standards.Finally, We get conclusions are as follows. First, primary,.prosperous and declining stages of development of exotic traditional medicine are Qin and Han, Song-Jin-Yuan, Ming and Qing Dynasties, respectively. Second, according to literature, the stage that has the most species of exotic medicine is song dynasty,approximately have 300. Removing repeating and doubtful species, the believable species are approximate 230 to 250. Meanwhile, the unknown species are approximate 30, which may be different name of one medicine or processed goods, now these medicines are named as "doubtful species". Third, the medicinal parts of exotic medicine are different from Chinese medicine of Han nation. The number of Resin, fruits and seeds kind are more than root and rhizomes kind,mineral medicines are more than animal. Fourth, the major producing area of exotic medicine is some countries and territories related to the Silk Route in the history. Ultimately, this paper preliminarily figure out basic information of exotic medicine of different dynasty in China,that provide reference for learning study and decision of industrial development.

Influence of Arabian Pharmacy on Diseases Tretament During Ottoman's Period in Bosnia and Herzegovina.

The Arab cultural heritage was an era of invaluable preservation and development of numerous teachings, including biomedical sciences. The golden period of Arab medicine deserves special attention in the history of medicine and pharmacy, as it was the period of rapid translation of works from Greek and Persian cultures into Arabic. They preserved their culture, and science from decay, and then adopted them to continue building their science on theirs as a basis. After the fall of Arabian Caliphate, Arabian pharmacy, continued to persevere, and spread through Turkish Caliphate until its fall in the First World War. That way, Arabian pharmacy will be spread to new areas that had benefited from it, including the area of occupied Bosnia and Herzegovina. Because of the vast territorial scope of the Ottoman Empire, the focus of this paper is description of developing pharmacy in Bosnia and Herzegovina during the time of Ottoman reign.

Pharmacy, Testing, and the Language of Truth in Renaissance Italy.

This article examines the role of testing and innovation in sixteenthcentury Italian pharmacy. I argue that apothecaries were less concerned with testing drugs for efficacy or creating novel products than with reactivating an older Mediterranean pharmacological tradition and studying the materials on which it relied. Their practice was not driven by radical experimentation but by a "culture of tweaking"-of minute operational changes to existing recipes and accommodation of their textual variants-which was rooted in the guild economy fostering incremental over radical innovation and in a humanist reevaluation of past autorities. Workshop practice was also increasingly driven by a new ideal of staying true to nature fostered by the period's botanical renaissance. This led to an emphasis on ingredients over processes in the shop, and found clearest expression in the elaboration of a taxonomic "language of truth" that helped apothecaries discern between authentic and inauthentic materia medica and harness their sincerity in lieu of testing effectiveness.

[Discussion on medicinal history and germplasm resource of Clinopodium Herba].

By sorting out the literature on materiamedica, it is found that medicinal history of ClinopodiumHerba is rather long which can be traced back to caoxuejiein Lüchan yan ben cao (Mountainous Materia Medica) with definite efficacy and usage; it is generally believed that the original plant of ClinopodiumHerba is Clinopodiumpolycephalum (Vaniot) C. Y. Wu et Hsuan and C. chinensis (Benth.) O. Kuntze are two separate species, also some scholarsclaim that C. polycephalum and C. chinensisare the same plant. But I think C. polycephalum is the main origin of ClinopodiumHerba, and the relationship of C. polycephalum and C. chinensis maybe a species and its variety.

[History and development of carbonization of Chinese materia medica and exploration on its mechanism of hemostatic action].

The first material recorded about hair charcoal is seen in Nei jing (Inner Canon). It has a history of over 2 000 years for the carbonization of Chinese materia medica. There were controversies on this matter and its clinical application was seldom seen and underdeveloped. After the Yuan Dynasty, the main theory of carbonic herbs for hemostasis, and keeping the nature of the medicines after carbonization was gradually formed, and physicians of generations began to conduct in-depth research. Through repeated practice and verification, people summed up the suitable species of Chinese materia medica and its principle for carbonization. The methods and degree of carbonization of Chinese materia medica are reasonably discussed, with its principle and basis for application primarily interpreted.

From Pharmacognosia to DNA-Based Medicinal Plant Authentication - Pharmacognosy through the Centuries.

For centuries, pharmacognosy was essential for the identification, quality, purity, and, until the end of the 18th century, even for the efficacy of medicinal plants. Since the 19th century, it concentrated on authenticity, purity, quality and the analysis of active substances, and was established as an academic branch discipline within pharmacy and continuously developed into a modern, highly sophisticated science. Even though the paradigm in pharmacy changed in the 19th century with the discovery of morphine and concentrated on single substances that could be synthesized fast by the upcoming industry, medicinal plants always remained an important element of the Materia medica, and during the last decades, medicinal plants continue to be a source of remedies, and natural products are an inspiration for new medicine. In this research, pharmacognostic skills remain an essential element, both with regards to identity, quality assurance of botanicals (both herbal medicines and supplements), and the discovery and development of new medicines. Over the years, the specific pharmacognostical tools have changed dramatically, and most recently, DNA-based techniques have become another element of our spectrum of scientific methods.

[Research on Japanese monograph of comprehensive dietetic materia medica, the Pao chu bei yong wo ming ben cao (Japanese Materia Medica Prepared for Kitchen)].

Japanese physicians of Edo Period (1603-1867) wrote many dietetic books, by combining the knowledge system (content and compiling style) and thoughts of diet therapy from China with local condition in Japan. Among them, the Pao chu bei yong wo ming ben cao(Japanese Materia Medica Prepared for Kitchen), written by Mukai Genshou, a physician in the early Edo, is the earliest comprehensive work of dietetic materia medica. In this book, the choice and usage of Japanese dietetic materia medica reveals obvious Japanese local color, including the name, morphology, cultivation, collection, identification, nature and flavor, and indication etc., reflecting the sprouting idea of edible herbal plant at the beginning of Edo period and the characteristic of absorbing Chinese diet thoughts by Japanese physician. This is the important first-hand historical material to understand the development of Japanese dietetic herbalism in early Edo and its dietotherapy culture.
