This paper investigates some of the ways that Chinese medicine has been transferred to the Western world and to Islamic territories. During the Golden Age of Islam (8th to 13th century CE), the herbal drug trade promoted significant commercial and scientific exchange between China and the Muslim world. Chinese herbal drugs have been described by medieval Muslim medical scholars such as Tabari (870 CE), Rhazes (925 CE), Haly Abbas (982 CE), Avicenna (1037 CE) and Jurjani (1137 CE). The term al-sin (the Arabic word for China) is used 46 times in Avicenna's Canon of Medicine in reference to herbal drugs imported from China. Cinnamon (dar sini; "Chinese herb"), wild ginger (asaron), rhubarb (rivand-e sini), nutmeg (basbasa), incense tree wood (ood), cubeb (kababe) and sandalwood (sandal) were the most frequently mentioned Chinese herbs in Islamic medical books. There are also multiple similarities between the clinical uses of these herbs in both medical systems. It appears that Chinese herbal drugs were a major component of the exchange of goods and knowledge between China and the Islamic and later to the Western world amid this era.

BACKGROUNDThe Chinese medical archive, Shang-Han Lun, is said to be written by ZHANG Zhong-jing (150 - 219 A.D.). This great influential work introduced the specific symptoms of six-channel disorders (Tai-Yang, Yang-Ming, Shao-Yang, Tai-Yin, Shao-Yin, and Jue-Yin) and their corresponding treatments, the combined syndromes, deterioration due to malpractice, and the concept of six-channel transitions. The concept of Shang-Han Lun is widely accepted by Chinese herbal doctors. However, no clinical data about Shang-Han symptoms are described in oriental or western medical reports.

METHODSThe clinical prescription data of traditional Chinese medicine visits were extracted under the National Health Insurance in Taiwan. The application rate of 42 Shang-Han formulae in clinical practice was analyzed in detail with the software SPSS.

RESULTSBetween 1999 and 2002, the prescription rate of Shang-Han formula was only 5.22% among a total of 528 889 576 Chinese herbal formula prescriptions. The most frequently used formula was Tai-Yang formulae (71.31%), followed by Shao-Yang formulae (17.49%) and the most commonly prescribed individual Shang-Han formulae were Ge-Gen Tang (16.11%), Shao-Yao-Gan-Cao Tang (12.97%), Xiao-Qing-Long Tang (11.79%), Ban-Xia Xie-Xin Tang (10.24%), and Xiao-Chai-Hu Tang (9.11%), which comprised 60.22% of the utilization rate of total Shang-Han formulae.

CONCLUSIONSFrom the prescription patterns of Shang-Han formulae, there was no evidence of transitions among the six channels. Despite the fundamental role of Shang-Han Lun in traditional Chinese medicine, prescription of Shang-Han formulae was limited in clinical practice.

To explore a key approach for improving therapeutic efficacy of traditional Chinese medicine by means of increasing its dosage. The rationality, necessity and feasibility of this proposition were explained and verified by the retrospective and prospective analysis about the current situation of therapeutic efficacy of traditional Chinese medicine, the relationship between dosage and therapeutic efficacy of traditional Chinese medicine, the rationality of conventional dosage specification. The unremarkable therapeutic efficacy was the main reason of traditional Chinese medicine to be denounced frequently, which was heavily due to its low dosage. However, many cases showed excellent therapeutic efficacy if a big dosage was used. Compared with the clinical dosage of western medicine and curative dose of active substance from traditional Chinese medicine or crude drugs, the specification of the conventional dosage of traditional Chinese medicine failed to be rigorous and objective. The viewpoint of "Cooking pot size limitation" and "Human stomach size limitation" may be the bottleneck which restricted the increase of traditional dosage. In conclusion, to increase the dosage of traditional Chinese medicine and elucidate the relationship between dosage and therapeutic efficacy would be a momentous and essential method to improve the therapeutic efficacy of traditional Chinese medicine.

The syndrome differentiation standardization of Chinese medicine and treatment technologies is the premise of Chinese medicine's entry into the world. But its individualized diagnosis and therapeutic features are contrary to the specification of standardization. The achievement and existent problems in syndrome differentiation standardization of Chinese medicine and treatment technologies were summarized in this paper. The thinking ways and recommendations to solve were proposed as well.

To interpret the traditional Chinese medicine (TCM) theory by the network technology, in order to promote the modernization and programming of studies on compatibility of TCMs. In this paper, efforts were made to express the direct interactions between drugs through the herb-pair network, analyze the community characteristics of the network and its relations with blood-Qi theory, and study the expression of blood-Qi theory on the herb-pair network through prescriptions. According to the findings, the herb-pairs network showed a strong community structure characteristics; Each community is composed of a series of herb pairs with close correlations, and either blood efficacy or Qi efficacy but not both of them. Based on that, the 386 single TCM ingredients involved by the herb-pair network were divided into three types of communities: Blood (B) community, Qi (Q) community and uncertain community. According to the statistical results of 262 prescriptions mapped onto the three types of communities, if a prescription contains single herbs of the Q community, the probability that it contains single herbs o the B community is 99.84%; Meanwhile, there are 140 prescriptions containing single herbs of both the Q community and the B community. The result is completely coincident with the TCM Blood-Qi theory that single herbs belong to both Q and B communities or the B community, because Qi regulation leads to blood regulation, but not vice versa. For example, a patient with hemorrhage due to trauma or blood-heat, Qi tonifying prescriptions may aggravate hemorrhage. In this paper, authors found high-recognition macroscopic network numerical characteristics to network data reference for judging rationality of new prescriptions, and proved human blood and Qi relations from the perspective of data analysis.

The traditional Chinese medicine(TCM) contains very complex constituents. Besides the major constituents, there are a large number of unclear trace constituents with novel skeletons and potent bioactivities, which have been regarded as one of the important therapeutic substances and the great resources of innovative drugs derived from TCM. The present review highlighted that the development of the trace therapeutic substances of TCM is closely depends on the advanced technologies for their identification, isolation, structure elucidation, and bioactivity evaluation. Additionally, this paper reviewed the novel trace compounds derived from Chinese herbal medicines which have been published in Organic Letters during 2001-2021, and summarized the important licensed drugs originated from the trace therapeutic substances and the discovery and development of trace therapeutic substances of 8 kinds of Chinese herbal medicines. This review provides references for the research and development of TCM therapeutic substances and innovative drugs.

In recent years, new preparations of traditional Chinese medicines (TCMs) have been developed, increasing the need for their clinical trials. Using placeboes rather than control drugs is increasingly popular in clinical trials of TCMs, as the therapeutic effects of the tested TCMs can be more properly judged. The basic attributes of TCM placeboes include similarity, safety, applicability and controllability. In particular, it is necessary to have similarities in appearance, color, smell and taste between the tested TCMs and placeboes. This is quite difficult for some TCMs due to their distinctive smell and taste. On the other hand, according to the TCM theory on homology of medicine and food, many foods also have certain bioactivities, potentially further complicating the selection of materials for TCM placeboes. In this review, firstly, studies on the special smell and taste of TCMs were introduced. Then, the preparation quality evaluation processes for TCM placeboes were summarized and discussed, based on the relevant literature published in recent years and the research results from our own lab. This review will facilitate the further research and development of TCM placeboes.

Quality control is pivotal in the research and development of traditional Chinese medicine, whose connotation is not limi-ted to the qualitative or quantitative detection of an indicator component, but extends to the establishment of a whole process quality control system from the perspective of pharmaceutical product lifecycle management. This study discussed the quality control strategy of Chinese medicine based on the concept of pharmaceutical product lifecycle management, and proposed the following suggestions:(1) to focus on the "holistic view" and "phased" characteristics of quality control and strengthen the establishment of quality control strategy based on top-level design;(2) to strengthen the research on quality control of Chinese medicine based on quality risk management, focus on the correlations of quality control indicators with the safety and effectiveness of traditional Chinese medicine, and establish a quality evaluation system consistent with the characteristics of traditional Chinese medicine;(3) to consider the characteristics of different registration classifications in the establishment of quality control strategy;(4) to highlight the quality correlation research, strengthen the quality transfer research, ensure the quality traceability, and establish a sound quality management system;(5) to strengthen the quality research on marketed drugs to achieve dynamic quality improvement.

The fundamental principle of traditional Chinese medicine(TCM) is holism, and it is crucial for TCM to address the key issue of the "holistic view" of Chinese herbal medicine. While the overall regulatory effects of Chinese herbal medicine have been widely recognized, the holistic internal logic of individual ingredients of Chinese herbal medicines require further clarification. In order to comprehensively understand the mechanism of action of Chinese herbal medicine, this paper combined the holistic view of Chinese herbal medicine with differentiation thinking to explore the intrinsic logical relationships within Chinese herbal medicine. Starting from the perspective of the coexistence of multiple components in Chinese herbal medicine, this paper systematically examined the "self-consistent" phenomenon within single Chinese herbal medicine. This phenomenon refers to the consistent or opposing actions of various components in terms of their physical and chemical properties, pharmacokinetic effects, biological effects, flavors and properties, and TCM efficacy. The paper summarized various logical relationships of syndrome differentiation exhibited by the same Chinese herbal medicine, analyzed the underlying reasons, and focused on analyzing external factors affecting the "self-consistent" phenomenon in the efficacy of Chinese herbal medicine, aiming to better elucidate the theoretical basis of the pharmacological effects of Chinese herbal medicine, further enrich the scientific connotation of the holistic view of Chinese herbal medicine, and provide theoretical guidance for the preparation process, compatibility patterns, and formulation design of Chinese herbal medicine.
