RESUMEN
Chinese materia medica has a wide range of clinical applications， but it has many active ingredients with different physicochemical properties， and the target organs， action pathways and mechanisms for different ingredients to exert their efficacy are not the same. Therefore， it is difficult to design and develop a co-delivery system loading multiple components of Chinese materia medica to maximize the synergistic therapeutic efficiency. Based on the characteristics of effectiveness and functionality of active ingredients， the strategies for multi-component co-delivery of Chinese materia medica can be categorized into two types：firstly， based on the effectiveness of active ingredients， new carriers such as liposomes， nanoparticles can be constructed to load multi-components of Chinese materia medica. secondly， based on the functionality of some active ingredients of Chinese materia medica， they are employed in the construction of co-delivery system， which can give play to the dual characteristics of their own efficacy and preparation functions. In this paper， we summarized the relevant research progress of the above two types of multi-component co-delivery strategies， and mainly discussed the pharmaceutical functions of the active ingredients in co-delivery systems， in order to find a more suitable multi-component co-delivery strategy， promoting the design and development of new delivery systems of Chinese materia medica.

RESUMEN
Toxic Chinese materia medica has been highly valued by its specialized and effective effects， but its safe application has become an urgent clinical problem to be solved. Compatibility for toxic attenuation is an important method for the rational clinical application of toxic Chinese materia medica as well as the promotion of its therapeutic advantages. The theory of “heterogeneous medicinals mutual restriction” elaborated in this article has been formed through long-term clinical practice and cognition， and refinement of clinical experience， which means that the nature partiality of toxic Chinese materia medica can be adjusted， and the toxicity can be suppressed through reasonable combination with herbal medicinalsof different properties， flavors， and effects. This theory covers the modes of compatibility for toxicity attenuation and the interaction relationships， like the restriction of medicinals with different properties and flavors， restriction of medicinals with different effects， and inhibiting toxins by reinforcing healthy qi. The opposite and complementary effects of various medicinals combinations are an extension of the connotations of this theory， and the principles can be explained from material basis and mechanism of action. Under the guidance of this theory， it is possible to optimize the compound prescription strategies of toxic Chinese materia medica， and provide new strategies for the clinical combinations of toxic Chinese materia medica， thereby achieving the reduction of toxicity and enhancement of effectiveness of the compound formulas.
RESUMEN
The Republic of China period （1912—1949） was an important stage of transition from traditional herbalism to clinical Chinese materia medica. The clinical application of Chinese materia medica became the focus of academic attention. During the Republic of China period， the research objectives， methods， and content of clinical Chinese materia medica were clarified， and the basic framework of Chinese materia medica was established through efficacy classification and item description. Based on the historical background at that time， striving for survival in adversity were the internal factors driving the construction of clinical Chinese materia medica， and the rise of academic education and the popularity of traditional Chinese medicine journals provided favorable conditions for the development of clinical Chinese materia medica. The clinical Chinese materia medica during the Republic of China period gradually formed a theoretical structure and core content that was distinctly different from that of traditional herbal medicine， which was integrated with the scientific research of Chinese materia medica and promoted the continuous development of Chinese materia medica together with other subdisciplines， presenting distinctive characteristics of the times and important academic significance.
RESUMEN
ObjectiveTo clarify the scientific validity of in vivo pharmacokinetic determination of the whole drug composition in Shenbai nanosuspension in rats， and to provide methodological guidance and theoretical basis for the in vivo study of multi-component complex system of traditional Chinese medicine（TCM） preparations. MethodThe concentration of the overall components， mainly total saponins and total polysaccharides in Shenbai decoction and Shenbai nanosuspension， was determined in rat plasma at different times by area under the absorbance-wavelength curve method（AUAWC）， and the concentration of individual ginsenoside Rg1 was determined by high performance liquid chromatography（HPLC）， and the methodology was verified. The pharmacokinetic parameters of the whole component were compared with those of ginsenoside Rg1 to evaluate the in vivo operational characteristics of the two preparations. ResultThe methodological investigations of AUAWC and HPLC were in accordance with the requirements. AUAWC analysis showed that the overall components in both the decoction group and the nanosuspension group showed a one-compartment model， with half-life（t1/2） of 2.43 h and 2.04 h， respectively. The relative bioavailability of Shenbai nanosuspension was 138.99%. HPLC assay showed that ginsenoside Rg1 in the decoction group and the nanosuspension group showed a two-compartment model， with distribution half-life（t1/2α） of 0.13 h and 2.55 h， and elimination half-life（t1/2β） were 14.28 h and 3.85 h， respectively. The relative bioavailability of Shenbai nanosuspension was 127.49%. Compared with Shenbai decoction， the time to peak（tmax）， peak concentration（Cmax） and area under the drug-time curve（AUC） of the overall components and ginsenoside Rg1 in Shenbai nanosuspension were increased. ConclusionThe established AUAWC can be used for the pharmacokinetic study of the overall components of TCM preparations， which is complementary to the results of individual components measured by HPLC， and can provide useful reference for the in vivo study of new dosage forms of TCM.
RESUMEN
ObjectiveTo develop traditional Chinese medicine （TCM） formulae for the treatment of nonsevere coronavirus disease 2019 （COVID-19） and to explore its anti-inflammatory mechanism. MethodsThe dysregulated signaling pathways were determined in macrophages from bronchoalveolar lavage fluid of COVID-19 patients and in lung epithelial cells infected with SARS-CoV-2 in vitro based on transcriptome analysis. A total of 102 TCM formulae for the clinical treatment of nonsevere COVID-19 were collected through literature. The pathway-reversing rates of these formulae in macrophages and lung epithelial cells were evaluated based on signature signaling pathways， and the basic formula was determined in conjunction with TCM theory. The commonly used Chinese materia medica for nonsevere COVID-19 were summarized from the 102 TCM formulae as abovementioned. And together with the screening results from the Pharmacopoeia of the People's Republic of China， a “Chinese materia medica pool” was esta-blished for the development of TCM formulae for COVID-19. The regulatory effects of each herb on signaling pathways were obtained based on targeted transcriptome analysis. Oriented at reversing dysregulated signaling pathways of COVID-19， the calculation was carried out， and the artificial intelligent methods for compositing formulae， that are exhaustive method and parallel computing， were used to obtain candidate compound formulas. Finally， with reference to professional experience， an innovative formula for the treatment of nonsevere COVID-19 was developed. The ethanol extract of the formula was evaluated for its anti-inflammatory effects by detecting the mRNA expression of interleukin 1b （Il1b）， C-X-C motif chemokine ligand 2 （Cxcl2）， C-X-C motif chemokine ligand 10 （Cxcl10）， C-C motif chemokine ligand 2 （Ccl2）， nitric oxide synthase 2 （Nos2）， and prostaglandin-endoperoxide synthase 2 （Ptgs2） using reverse transcription-quantitative polymerase chain reaction （RT-qPCR） in RAW264.7 cells treated with lipopolysaccharide （LPS）. ResultsIn macrophages and lung epithelial cells， 34 dysregulated signaling pathways associated with COVID-19 were identified respectively. The effects of the 102 formulae for clinical treatment of nonsevere COVID-19 were evaluated based on the dysregulated signaling pathways and targeted transcriptome， and the result showed that Yinqiao Powder and Pingwei Powder （银翘散合平胃散， YQPWP） ranked first， reversing 91.18% of the dysregulated signaling pathways in macrophages and 100% of the dysregulated signaling pathways in lung epithelial cells. Additionally， YQPWP had the function of scattering wind and clearing heat， resolving toxins and removing dampness in accordance with the pathogenesis of wind-heat with dampness in COVID-19. It was selected as the basic formula， and was further modified and optimized to develop an innovative fomula Qiaobang Zhupi Yin （翘蒡术皮饮， QBZPY） based on expert experience and artificial intelligence in composing formulae. QBZPY can reverse all the dysregulated signaling pathways associated with COVID-19 in macrophages and lung epithelial cells， with the reversing rates of 100%. The chief medicinal of QBZPY， including Lianqiao （Fructus Forsythiae）， Xixiancao （Herba Siegesbeckiae） and Niubangzi （Fructus Arctii）， can down-regulate multiple signaling pathways related with virus infection， immune response， and epithelial damage. RT-qPCR results indicated that compared with the model group， the QBZPY group down-regulated the mRNA expression of Il1b， tumor necrosis factor （Tnf）， Cxcl2， Cxcl10， Ccl2， Nos2 and Ptgs2 induced by LPS in RAW264.7 cells （P＜0.05 or P＜0.01）. ConclusionBased on targeted transcriptome analysis， expert experience in TCM and artificial intelligence， QBZPY has been developed for the treatment of nonsevere COVID-19. The ethanol extract of QBZPY has been found to inhibit mRNA expression of several pro-inflammatory genes in a cellular inflammation model.
RESUMEN
Similia Similibus Curantur is also called the law of similars. That is, when a drug produces pathological/pathogenic symptoms in healthy individual means, the same drug can relieve similar kinds of symptoms in individuals with the disease. The biological, pharmacological and toxicological action of capsaicin alkaloids is a perfect example to explain the Similia Similibus Curantur principle. Most of the drugs in homoeopathic materia medica contain toxicological, pharmacological, drug-proving, and traditional use-related symptoms and indications. Abnormal sensations and symptoms of the disease are caused by the involvement of a specific receptor or molecular pathway and gene functions. These receptors or molecules may be stimulated or suppressed by environmental, natural or artificial agents. In such conditions, the administration of specific homoeopathic medicine having a similar kind of affinity towards the particular receptors or molecules involved in the disease process leads to modulation of such receptor or molecular pathways (e.g., desensitization, sensitization, inhibition). These kinds of actions cause the betterment of symptoms or curative effects. So “Similia similibus curanter” can be understood as a similar receptor or molecular pathway involved in both drug molecules biological/ pharmacological and toxicological action and disease pathogenesis". The selection of medicine is by comparing the similarity between the receptor or molecular pathway in disease pathogenesis and drug pathogenesis. To avoid unwanted aggravations or side effects while using mother tinctures or solutions, administer them less than their physiological dose. The theory of the pharmacological basis of Similia Similia Curantur creates a rational method to apply this Similia Principle. Based on this theory, there is a possibility of discovering Novel drugs in the future that acts and gives a cure in similia similibus curantur way.
RESUMEN
Safety is the core of the quality of Chinese materia medica products， and microbial pollution caused by medicinal materials， decoction pieces， intermediate products and others can bring certain impact on the quality and safety of Chinese materia medica products. The reasons for this are not only the problems of medicinal materials themselves， but also the exogenous pollution introduced in the production process. How to effectively use microbial detection technology and establish an appropriate microbial quality control strategy in the whole process of Chinese materia medica production is of great significance to improve the quality of Chinese materia medica products. Therefore， the authors put forward a microbial quality control strategy in the whole process of Chinese materia medica production based on the guidance of quality by design （QbD） concept， emphasizing the scientific linkage between the internal and external microbial quality control systems to jointly ensure the quality of products in all aspects. Among them， the internal microbial quality control system includes the control of the whole chain of Chinese materia medica-decoction pieces-intermediate products-excipitents-packaging materials-final products， which should be carried out by stages and characteristics， while the external microbial quality control system includes the control of personnel-equipment and facilities-pharmaceutical water-environment， emphasizing the principle of quality risk management and the development of monitoring programs， aiming to closely integrate microbial quality risk management with the production process of Chinese materia medica products， and to classify and develop microbial control strategies in order to minimize the impact of contaminating microorganisms and effectively guarantee the quality of Chinese materia medica products.
RESUMEN
"Taking drugs for a long term" is a qualitative expression of medication method based on the efficacy and safety of Chinese medicine, and the study on it is conducive to the full utilization of the efficacy and rational use of drugs. There are 148 drugs that can be taken for a long time recorded in Shen Nong's Classic of Materia Medica, accounting for 41% of the total drugs. This paper analyzed three-grade classification, natural qualities, four properties and five flavors, and efficacy features of the "long-term taking" drugs(LTTD), thus exploring the herbal source of traditional Chinese medicine health care and the rationality of effect accumulation by long-term taking. It was found that there were more than 110 top-grade LTTD in Shen Nong's Classic of Materia Medica, most of which were herbs, with sweet flavor, flat property, and no toxicity. The efficacies were mainly making body feel light and agile(Qingshen) and prolonging life. Eighty-three LTTD were included in the Chinese Pharmacopoeia(2020 edition). In the modern classification, tonic LTTD accounted for the most, followed by damp-draining diuretic LTTD and exterior-releasing LTTD. Twenty LTTD were included in the "List of Medicinal and Edible Products" and 21 were in the "List of Products Used for Health-care Food", involving in various modern health care effects, such as enhancing immunity, assisting in reducing blood lipids, and anti-oxidation. Shen Nong's Classic of Materia Medica is the classic source of traditional Chinese medicine health care, and its medication thought of taking drugs for a long term to accumulate effects has guiding significance for the regulation of sub-health and chronic diseases nowadays. The efficacy and safety of LTTD have been examined in practice for a long time, and some of the drugs are edible, which is unique in the whole cycle of health-care service, especially in line with the health-care needs in the aging society under the concept of Big Health. However, some records in the book are limited by the understanding of the times, which should be scientifically studied according to the Chinese Pharmacopoeia and the related regulations and technical requirements, under the attitude of eliminating falsifications and preserving the truth and keeping the right essence, so as to achieve further improvement, innovation, and development.

Various omics and their combined techniques have certain applications in the study of the mechanism of toxicity of Chinese materia medica, the screening of toxic biomarkers, and the prediction of the toxicity of Chinese materia medica. It has been found that the current application scope of exploring the toxicity of Chinese materia medica based on omics technology still needs to be expanded. In terms of organ damage caused by Chinese materia medica, omics technology is mostly used to study hepatotoxicity. In terms of the attenuation mechanism of TCM, proteomics and metabolomics have more advantages, and the two have potential prospects in exploring the processing or compatibility of TCM to reduce toxicity and increase efficiency. The combination of omics technology with network pharmacology, bioinformatics and other technologies is more conducive to providing references for the in-depth study of the toxicity of Chinese materia medica.
RESUMEN
By the end of 2021, a total of 915000 cases of occupational pneumoconiosis and 450000 existing cases have been reported nationwide. Silicosis is a common and serious pneumoconiosis disease caused by long-term inhalation of large amounts of free silica dust and extensive nodular fibrosis in the lungs. Because its specific pathogenic mechanism has not been elucidated and the relevant research progress is slow, there is still a lack of effective therapeutic and interventional drugs. With the increase of national attention and the unique advantages of Chinese materia medica in the treatment of silicosis, more and more studies have been conducted on the treatment of silicosis with active ingredients of Chinese materia medica in China, but most of them are still in preclinical research stage. This article mainly introduced the pharmacological action and mechanism of selected active components of Chinese materia medica in the intervention of silicosis from three aspects: anti-inflammation, anti-oxidation, and intervention of apoptosis, providing ideas for subsequent research and development of new drugs for silicosis. This article argues, it is considered that some traditional Chinese medicines must observe the pathological changes in the treatment of silicosis in the overall animal experiment, clarify their pharmacodynamic effects, and further study the multiple targets and pathways involved in them to elucidate their specific mechanisms of action. At the same time, it can strengthen the analysis of active ingredients of traditional Chinese medicine, or modify the structure of active ingredients, and then enhance its pharmacological activity in the treatment of silicosis, realizing the transformation of preclinical research stage to the results of clinical research.
RESUMEN
ObjectiveTo collect and analyze the properties and application characteristics of external use of roots and rhizomes of Chinese herbal medicines in the Chinese Materia Medica（《中华本草》） to provide data references for the research on clinical external use of Chinese medicine， in order to provide data reference for clinical external use of traditional Chinese medicine（TCM）. MethodThe Chinese herbal medicines included in the Chinese Materia Medica were systematically screened. The inclusion criterion was the explicit mention of terms like "root", "rhizome", "root bark", "tuber", "tuberous root", etc. under the "Source" in the Chinese Materia Medica. Information on properties, flavors, meridian tropism, medicinal parts, fresh use, toxicity, efficacies and indications, and dosage of roots and rhizomes of Chinese herbal medicines was collected. The information was then entered into an Excel spreadsheet for statistical analysis. ResultThe Chinese Materia Medica records 2 662 roots and rhizomes of Chinese herbal medicines, of which 1 653 are suitable for external use. The predominant properties and flavors are cool, cold, bitter, pungent, and sweet. These Chinese herbal medicines mainly act on the liver, lung, and spleen meridians. The primary medicinal parts used include root, rhizome, and root bark. More than half of the roots and rhizomes of Chinese herbal medicines can be used in their fresh form. The main efficacies include clearing heat, removing toxins, resolving stasis, dispersing accumulation, resolving blood stasis and stopping bleeding, reducing swelling and alleviating pain, dispelling dampness and relieving pain. The main indications are skin sores, traumatic injuries, and rheumatic diseases. Common external application methods include poultice, decoction for washing, and applying powdered form. Most of these Chinese herbal medicines lack specific dosage guidelines for external use, with an emphasis on using an appropriate amount. ConclusionThe Chinese Materia Medica contains a wide range of roots and rhizomes of Chinese herbal medicines suitable for external use, with definite therapeutic effects, providing a broad perspective for the application of Chinese medicine externally. However, there are still problems such as unclear dosages and limited research. Further studies are necessary to better utilize the advantages of the external use of Chinese medicine.

RESUMEN
Scutellariae Radix， Coptidis Rhizoma， and Phellodendri Chinensis Cortex are three commonly used Chinese herbal medicines， and their application in classic famous prescriptions cannot be fully explained by the triple energizer classification method. This study reviewed the ancient materia medica works and elaborated on the functions of the three herbal medicines before the Song dynasty and after the Jin dynasty. The works before the Song dynasty mainly introduced the diseases treated by the three herbal medicines according to the Shennong's Classic of Materia Medica（《神农本草经》）， and the works after the Jin dynasty mainly expounded the indications of the three medicines in the Shennong's Classic of Materia Medica according to the new medical theory. Although all the three herbal medicines can treat heat syndrome， digestive system diseases， skin and mucosa diseases， they act on different targets. Scutellariae Radix can regulate Qi stagnation and reverse caused by the fire syndrome. Coptidis Rhizoma can treat excess fire and purulent bloody stool caused by the deficiency of Zang-fu organs. Phellodendri Chinensis Cortex mainly treats the diseases of the intestine and reproductive system and can kill parasites. In addition， this paper summarized the descriptions about the functions of Scutellariae Radix in eliminating blood blockage， Coptidis Rhizoma in protecting the intestine， and Phellodendri Chinensis Cortex in clearing the liver in ancient books. According to the sentences in the Treatise on Febrile and Miscellaneous Diseases（《伤寒杂病论》）， the application of Scutellariae Radix in Chaihu prescriptions， Coptidis Rhizoma in Baitouweng Decoction， and Phellodendri Chinensis Cortex in Zhizi Baipi Decoction confirms to the indications of the three medicines in the materia medica works before the Song Dynasty. The existing clinical and pharmacological research results confirm the indications of the three herbal medicines in the ancient works. The clinical application of the three medicines should refer to the materia medicia works before the Song dynasty， so as to achieve precise medication.

Since the emergence of the term "materia medica", scholars have proposed different opinions on its concept. This term has been used to refer to traditional Chinese medicines, or medical books, or traditional pharmacology. Due to the differences in the concept of materia medica, scholars also have controversies about the concept of herbalism. Herbalism is usually understood as traditional Chinese pharmacology. After years of evolution, the term "herbalism" has now possessed the characteristics of an independent discipline, which can be defined as an applied basic discipline that comprehensively utilizes traditional and modern technological methods to study the formation, development, and changes of traditional pharmacology and reveal the basic theories and application laws of traditional medicine. At present, the research content of herbalism mainly includes three aspects: materia medica history, materia medica literature, and traditional pharmacology. This study explores the disciplinary concepts and main research content of herbalism based on a systematic review of the literature about the concepts of materia medica and herbalism, with the aim of attracting more attention to promote the establishment and development of the discipline of herbalism.
