Comprehensive survey of target prediction web servers for Traditional Chinese Medicine.

Traditional Chinese medicine (TCM) is characterized by multi-components, multiple targets, and complex mechanisms of action and therefore has significant advantages in treating diseases. However, the clinical application of TCM prescriptions is limited due to the difficulty in elucidating the effective substances and the lack of current scientific evidence on the mechanisms of action. In recent years, the development of network pharmacology based on drug systems research has provided a new approach for understanding the complex systems represented by TCM. The determination of drug targets is the core of TCM network pharmacology research. Over the past years, many web tools for drug targets with various features have been developed to facilitate target prediction, significantly promoting drug discovery. Therefore, this review introduces the widely used web tools for compound-target interaction prediction databases and web resources in TCM pharmacology research, and it compares and analyzes each web tool based on their basic properties, including the underlying theory, algorithms, datasets, and search results. Finally, we present the remaining challenges for the promising future of compound-target interaction prediction in TCM pharmacology research. This work may guide researchers in choosing web tools for target prediction and may also help develop more TCM tools based on these existing resources.

A Combination of Deep-Sea Water and Fucoidan Alleviates T2DM through Modulation of Gut Microbiota and Metabolic Pathways.

Fucoidan and deep-sea water (DSW) are attractive marine resources for treating type 2 diabetes (T2DM). In this study, the regulation and mechanism associated with the co-administration of the two were first studied using T2DM rats, induced by a high fat diet (HFD) and streptozocin (STZ) injection. Results demonstrate that, compared to those with DSW or FPS alone, the orally administered combination of DSW and FPS (CDF), especially the high dose (H-CDF), could preferably inhibit weight loss, decrease levels of fasting blood glucose (FBG) and lipids, and improve hepatopancreatic pathology and the abnormal Akt/GSK-3ß signaling pathway. The fecal metabolomics data show that H-CDF could regulate the abnormal levels of metabolites mainly through the regulation of linoleic acid (LA) metabolism, bile acid (BA) metabolism, and other related pathways. Moreover, H-CDF could adjust the diversity and richness of bacterial flora and enrich bacterial groups, such as Lactobacillaceae and Ruminococcaceae UCG-014. In addition, Spearman correlation analysis illustrated that the interaction between the gut microbiota and BAs plays an essential role in the action of H-CDF. In the ileum, H-CDF was verified to inhibit activation of the farnesoid X receptor (FXR)-fibroblast growth factor 15 (FGF15) pathway, which is regulated by the microbiota-BA-axis. In conclusion, H-CDF enriched Lactobacillaceae and Ruminococcaceae UCG-014, thereby changing BA metabolism, linoleic acid metabolism, and other related pathways, as well as enhancing insulin sensitivity and improving glucose and lipid metabolism.

Research Progress on Nanoplatforms and Nanotherapeutic Strategies in Treating Glioma.

Glioma is the most common and aggressive primary intracranial tumor within the central nervous system. The blood-brain barrier (BBB) has been a great hurdle for an effective glioma treatment. To effectively treat glioma, various strategies have been applied to deliver drugs to the brain by crossing the BBB. Nanocarrier-mediated drug delivery is emerging as an effective and noninvasive system to treat glioma, showing great potential in glioma therapy. In this review, we will provide a comprehensive overview on nanocarrier-mediated drug delivery and related glioma therapy. Following an initial overview of the BBB and blood-brain-tumor barrier (BBTB) structure and characteristics, nanocarrier-mediated drug delivery strategies (liposomes, micelles, inorganic systems, polymeric nanoparticles, nanogel system, biomimetic nanoparticles, and exosomes) for crossing the BBB are discussed. Finally, nanotherapeutic techniques (imaging-mediated chemotherapy, photothermal therapy, photodynamic therapy, gene therapy, immunotherapy, ferroptosis therapy, sonodynamic therapy, chemodynamic therapy, and combination therapy) in treating glioma are summarized. In addition, this review provides some perspectives on the clinical applications of nanomedicines.

Potential activity of Traditional Chinese Medicine against Ulcerative colitis: A review.

ETHNIC PHARMACOLOGICAL RELEVANCE: Plant materials are used as complementary and alternative therapies all over the world for the treatment of various diseases. Ulcerative colitis (UC), a chronic nonspecific inflammatory bowel disease listed as one of the modern refractory diseases by the World Health Organization, has a long course, is challenging to cure, and is prone to cause cancer. Recent years have witnessed a growing trend of applying traditional Chinese medicine (TCM) to UC. AIM OF THIS REVIEW: This review presents an overview of the pathogenesis of UC and reports the therapeutic effect of TCM on UC (including TCM prescriptions, single TCM, and treatments using TCM ingredients) to provide a theoretical basis for the use of TCM in treating UC. METHODS: We performed a collection and collation of relevant scientific articles from different scientific databases regarding TCM and its usefulness in treating UC. In this paper, the therapeutic effect of TCM is summarized and analyzed according to the existing experimental and clinical research. RESULTS: There are positive signs that TCM primarily regulates inflammatory cytokines, intestinal flora, and the immune system, and also protects the intestinal mucosa. Hence, it can play a role in treating UC. CONCLUSION: TCM has a definite curative effect in the treatment of UC. It can alleviate and treat UC in a variety of ways. We should take syndrome differentiation and treatment differentiation as the basis. With the help of modern medicine, TCM's clinical curative effects can be enhanced for the treatment of UC.

Deep Sea Water Alleviates Tau Phosphorylation and Cognitive Impairment via PI3K/Akt/GSK-3ß Pathway.

Deep sea water (DSW), as a noticeable natural resource, has been demonstrated to contain high levels of beneficial minerals and exert marked anti-diabetes effects. Epidemiological studies show that type 2 diabetes mellitus (T2DM) is closely related to high danger of Alzheimer's disease (AD); moreover, Akt/GSK-3ß signaling is the main underlying pathway that connects these two diseases. Besides, it has been demonstrated that minerals in DSW, such as Mg, Se, and Zn, could effectively treat cognitive deficits associated with AD. Herein, we first observed the protection of DSW against cognitive dysfunction in T2DM rats, then furtherly explored the neuroprotective mechanism in SH-SY5Y cell model. In T2DM rats, DSW obviously elevated the concentrations of elements Mg, V, Cr, Zn, and Se in brain and improved learning and memory dysfunction in behavior assays, including Morris water maze (MWM) and new object recognition (NOR). Western blot (WB) results demonstrated that DSW could stimulate PI3K/Akt/GSK-3ß signaling, arrest Tau hyperphosphorylation at serine (Ser) 396 and threonine (Thr)231, which was confirmed by immunohistochemistry (IHC). In order to further confirm the mechanism, we employed wortmannin to inhibit PI3K in SH-SY5Y cells; results showed that pretreatment with wortmannin almost abolished DSW-induced decreases in phosphorylated Tau. Taken together, these data elucidated that DSW could improve Tau hyperphosphorylation and cognitive impairment, which were closely related with the stimulation of Akt/GSK-3ß signaling, and the neuroprotective effects of DSW should be contributed to the synergistic effects of major and trace elements in it, such as Mg, V, Cr, Zn, and Se. These experimental evidence indicated that DSW may be explored as natural neuroprotective food for the prevention and treatment of AD.

Peripheral ablation of type III adenylyl cyclase induces hyperalgesia and eliminates KOR-mediated analgesia in mice.

Ca2+/calmodulin-stimulated group I adenylyl cyclase (AC) isoforms AC1 and AC8 have been involved in nociceptive processing and morphine responses. However, whether AC3, another member of group I ACs, is involved in nociceptive transmission and regulates opioid receptor signaling remains elusive. Here, we report that conditional KO of AC3 (AC3 CKO) in L3 and L4 DRGs robustly facilitated the mouse nociceptive responses, decreased voltage-gated potassium (Kv) channel currents, and increased neuronal excitability. Furthermore, we report AC3 CKO eliminated the analgesic effect of κ-opioid receptor (KOR) agonist and its inhibition on Kv channel by classical Gαi/o signaling or nonclassical direct interaction of KOR and AC3 proteins. Interestingly, significantly upregulated AC1 level and cAMP concentration were detected in AC3-deficient DRGs. Inhibition of AC1 completely reversed cAMP upregulation, neuronal excitability enhancement, and nociceptive behavioral hypersensitivity in AC3-CKO mice. Our findings suggest a crucial role of peripheral AC3 in nociceptive modulation and KOR opioid analgesia.

"Efficacy-Nature-Structure" Relationship of Traditional Chinese Medicine Based on Chemical Structural Data and Bioinformatics Analysis.

Traditional Chinese medicines (TCMs) have wide pharmacological activities, and the ingredients in individual TCMs determine their efficacies. To understand the "efficacy-nature-structure" relationship of TCM, compounds from 2444 kinds of herbs were collected, and the associations between family, structure, nature, and biological activities were mined and analyzed. Bernoulli Naïve Bayes profiling and a data analysis method were used to predict the targets of compounds. The results show that genetic material determined the representation of ingredients from herbs and the nature of TCMs and that the superior scaffolds of compounds of cold nature were 2-phenylochrotinone, anthraquinone, and coumarin, while the compounds of hot nature were cyclohexene. The results of the similarity analysis and distribution for molecular descriptors of compounds show that compounds associated with the same nature were similar and compounds associated with different natures occurred as a transition in part. As for integral compounds from 2-phenylochrotinone, anthraquinone, coumarin, and cyclohexene, the value of the shape index increased, indicating the transition of scaffolds from a spherical structure to a linear structure, with various molecular descriptors decreasing. Three medicines and three recipes prescribed based on "efficacy-nature-structure" had a higher survival rate in the clinic and provided powerful evidence for TCM principles. The research improves the understanding of the "efficacy-nature-structure" relationship and extends TCM applications.

Antibacterial Activity Prediction Model of Traditional Chinese Medicine Based on Combined Data-Driven Approach and Machine Learning Algorithm: Constructed and Validated.

Traditional Chinese medicines (TCMs), as a unique natural medicine resource, were used to prevent and treat bacterial diseases in China with a long history. To provide a prediction model of screening antibacterial TCMs for the design and discovery of novel antibacterial agents, the literature about antibacterial TCMs in the China National Knowledge Infrastructure (CNKI) and Web of Science database was retrieved. The data were extracted and standardized. A total of 28,786 pieces of data from 904 antibacterial TCMs were collected. The data of plant medicine were the most numerous. The result of association rules mining showed a high correlation between antibacterial activity with cold nature, bitter and sour tastes, hemostatic, and purging fire efficacies. Moreover, TCMs with antibacterial activity showed a specific aggregation in the phylogenetic tree; 92% of them came from Tracheophyta, of which 74% were mainly concentrated in rosids, asterids, Liliopsida, and Ranunculales. The prediction models of anti-Escherichia coli and anti-Staphylococcus aureus activity, with AUC values (the area under the ROC curve) of 77.5 and 80.0%, respectively, were constructed by the Neural Networks (NN) algorithm after Bagged Classification and Regression Tree (Bagged CART) and Linear Discriminant Analysis (LDA) selection. The in vitro experimental results showed the prediction accuracy of these two models was 75 and 60%, respectively. Four TCMs (Cirsii Japonici Herba Carbonisata, Changii Radix, Swertiae Herba, Callicarpae Formosanae Folium) were proposed for the first time to show antibacterial activity against E. coli and/or S. aureus. The results implied that the prediction model of antibacterial activity of TCMs based on properties and families showed certain prediction ability, which was of great significance to the screening of antibacterial TCMs and can be used to discover novel antibacterial agents.

Identifying potential treatments of COVID-19 from Traditional Chinese Medicine (TCM) by using a data-driven approach.

ETHNOPHARMACOLOGICAL RELEVANCE: Traditional Chinese Medicine (TCM) has been widely used as an approach worldwide. Chinese Medicines (CMs) had been used to treat and prevent viral infection pneumonia diseases for thousands of years and had accumulated a large number of clinical experiences and effective prescriptions. AIM OF THE STUDY: This research aimed to systematically excavate the classical prescriptions of Chinese Medicine (CM), which have been used to prevent and treat Pestilence (Wenbing, Wenyi, Shiyi or Yibing) for long history in China, to obtain the potential prescriptions and ingredients to alternatively treat COVID-19. MATERIALS AND METHODS: We developed the screening system based on data mining, molecular docking and network pharmacology. Data mining and association network were used to mine the high-frequency herbs and formulas from ancient prescriptions. Virtual screening for the effective components of high frequency CMs and compatibility Chinese Medicine was explored by a molecular docking approach. Furthermore, network pharmacology method was used to preliminarily uncover the molecule mechanism. RESULTS: 574 prescriptions were obtained from 96,606 classical prescriptions with the key words to treat "Warm diseases (Wenbing)", "Pestilence (Wenyi or Yibing)" or "Epidemic diseases (Shiyi)". Meanwhile, 40 kinds of CMs, 36 CMs-pairs, 6 triple-CMs-groups existed with high frequency among the 574 prescriptions. Additionally, the key targets of SARS-COV-2, namely 3CL hydrolase (Mpro) and angiotensin-converting enzyme 2(ACE2), were used to dock the main ingredients from the 40 kinds by the LigandFitDock method. A total of 66 compounds components with higher frequency were docked with the COVID-19 targets, which were distributed in 26 kinds of CMs, among which Gancao (Glycyrrhizae Radix Et Rhizoma), HuangQin (Scutellariae Radix), Dahuang (Rhei Radix Et Rhizome) and Chaihu (Bupleuri Radix) contain more potential compounds. Network pharmacology results showed that Gancao (Glycyrrhizae Radix Et Rhizoma) and HuangQin (Scutellariae Radix) CMs-pairs could also interact with the targets involving in immune and inflammation diseases. CONCLUSIONS: These results we obtained probably provided potential candidate CMs formulas or active ingredients to overcome COVID-19. Prospectively, animal experiment and rigorous clinic studies are needed to confirm the potential preventive and treat effect of these CMs and compounds.

Chinese Marine Materia Medica Resources: Status and Potential.

Chinese marine materia medica (CMMM) is a vital part of traditional Chinese medicine (TCM). Compared with terrestrial TCM, CMMM, derived from specific marine habitats, possesses peculiar chemical components with unique structures reflecting as potent pharmacological activities, distinct drug properties and functions. Nowadays, CMMM appears to be especially effective in treating such difficult diseases as cancers, diabetes, cardio-cerebrovascular diseases, immunodeficiency diseases and senile dementia, and therefore has become an important medicinal resource for the research and development of new drugs. In recent years, such development has attracted wide attention in the field of medicine. In this study, the CMMM resources in China were systematically investigated and evaluated. It was found that the historic experiences of Chinese people using CMMM have continuously accumulated over a period of more than 3600 years, and that the achievements of the research on modern CMMM are especially outstanding. By June 2015, 725 kinds of CMMMs from Chinese coastal sea areas have been identified and recorded, covering 1552 organisms and minerals. More than 3100 traditional prescriptions containing CMMMs have been imparted and inherited. However, the number of CMMMs is less than the 8188 terrestrial TCMs, from more than 12,100 medicinal terrestrial plants, animals and minerals. In the future, the research and development of CMMM should focus on the channel entries (TCM drug properties), compatibility, effective ingredients, acting mechanisms, drug metabolism and quality standard. This study reveals the high potential of CMMM development.

[Effect of 5 warm-hot nature Chinese drugs for promoting blood circulation and removing blood stasis on 5-HT, NE, and endocrine hormones of rats of cold coagulation and blood stasis syndrome].

OBJECTIVE: To study the mechanism of warm-hot nature Chinese drugs (WHNCD) for promoting blood circulation and removing blood stasis (PBCRBS) for intervening model rats of cold coagulation and blood stasis syndrome (CCBSS). METHODS: CCBSS rat model was set up in outbred SD rats using ice water immersion method. Totally 300 successfully modeled CCBSS rats were randomly divided into 5 groups according to the principle of balance weight, 60 in each group. Contents of triothyrone (T3), tetraiodothyroine (T4), progesterone (P), 5-hydroxytryptamine (5-HT), and noradrenalin (NE) were paralleledly detected in all groups. Then rats in each group were subdivided into 6 subgroups as the model group, the curcuma group, the Ligsticum Chuanxiong group, the safflower group, the Rhizoma Corydalis group, and the Olibanumg group. Besides, 5 normal control groups were set up for 5 indices, 50 rats in total. We need 70 rats (7 groups) to finish observing 1 index, 350 rats in total for 5 indices. Except those in the model group and the normal control group, rats were administered with corresponding decoction at 20 g crude drugs/kg body weight by gastrogavage, 3 mL each time, once daily for 7 successive days. Equal volume of normal saline was given to rats in the normal control group and the model group. Contents of T3, T4, P, 5-HT, and NE were detected before treatment and 1 week after treatment. RESULTS: Compared with before treatment in the same group, T3 increased in the Ligsticum Chuanxiong group and the Olibanumg group, 5-HT increased in the Ligsticum Chuanxiong group, T4, NE, and P increased in all medicated groups (P < 0.05). Compared with the normal control group, contents of T3, T4, 5-HT, NE, and P in the model group decreased (P < 0.05). Compared with the model group, contents of T3, T4, 5-HT, and NE increased in each medicated group (P < 0.05). There was statistical difference in contents of P between the Ligsticum Chuanxiong group and the Olibanumg group (P < 0.05). CONCLUSIONS: WHNCD for PBCRBS had regulatory roles in serum contents of T3, T4, P, and NE in modeled rats of CCBSS. They could promote the thyroid gland-gonadal axis function, enhance the function of the endocrine system, which might be one of the pharmacodynamic mechanism of WHNCD for PBCRBS in intervening CCBSS.

[Textual research on the literature sources, its related names and medicinal part of Lonicera japonica Thunb].

The "jin yin hua" (Lonicera japonica Thunb.) used in the clinic nowadays is the flower of honeysuckle, excluding its stem, leave, branch, vine or the whole plant. In the early time, the name of "ren dong" (honeysuckle) or "ren dong teng" (Caulis lonicerae) didn't refer exclusively to the flower of honeysuckle. A few early literature, such as Xin xiu ben cao (Newly Revised Materia Medica) recorded briefly the flower, yet only mentions its time of blossom and shape without mentioning the medicinal use of its flower, nor the title of "jin yin hua", as the identification for this plant. Therefore, it cannot be regarded as the primary source of "jin yin hua". This research points out that the first appearance of the name of "jin yin hua" should be in Su shen liang fang (Su-Shen's Effective Prescriptions) of the Song Dynasty, and the first usage of the flower "jin yin hua" as a single drug was in Wai ke jing yao (Essence of External Diseases) of the Song Dynasty. Thus, the conclusion that "jin yin hua" is first seen in Xin xiu ben cao or lv chan yan ben cao (Mountainous Materia Medica) quoted in the ninth edition of teaching material of Traditional Chinese Pharmacology, and Chinese Materia Medica are all wrong and should be corrected accordingly.

Study on the networks of "Nature-Family-Component" of Chinese medicinal herbs based on association rules mining.

OBJECTIVE: To explore appropriate methods for the research of the theory of Chinese medicine nature property and find the relationship between Nature-Family-Component of Chinese herbs. METHODS: From perspective of systems biology, we used Associate Network to identify useful relationships among "Nature-Family-Component" of Herbs. In this work, Associate Network combines association rules mining method and network construction method to evaluate the complicate relationship among "Nature-Family-Component" of herbs screened. RESULTS: The results of association rules mining showed that the families had a close relationship with nature properties of herbs. For example, the families of Magnoliaceae, Araceae had a close relationship with hot nature with confidence of 100%, the families of Cucurbitaceae has a close relationship to cold nature with confidence of 90.91%. Moreover, the results of constructed Associate Network implied that herbs belonging to the same families generally had the same natures. In addition, some herbs belonging to different families may also have same natures when they contain the same main components. CONCLUSION: These results implied that the main components of herbs might affect their natures; the relationships between families and natures were based on the main compounds of herbs.

Study of the distribution patterns of the constituent herbs in classical Chinese medicine prescriptions treating respiratory disease by data mining methods.

OBJECTIVE: To provide the distribution pattern and compatibility laws of the constituent herbs in prescriptions, for doctor's convenience to make decision in choosing correct herbs and prescriptions for treating respiratory disease. METHODS: Classical prescriptions treating respiratory disease were selected from authoritative prescription books. Data mining methods (frequent itemsets and association rules) were used to analyze the regular patterns and compatibility laws of the constituent herbs in the selected prescriptions. RESULTS: A total of 562 prescriptions were selected to be studied. The result exhibited that, Radix glycyrrhizae was the most frequently used in 47.2% prescriptions, other frequently used were Semen armeniacae amarum, Fructus schisandrae Chinese, Herba ephedrae, and Radix ginseng. Herbal ephedrae was always coupled with Semen armeniacae amarum with the confidence of 73.3%, and many herbs were always accompanied by Radix glycyrrhizae with high confidence. More over, Fructus schisandrae Chinese, Herba ephedrae and Rhizoma pinelliae was most commonly used to treat cough, dyspnoea and associated sputum respectively besides Radix glycyrrhizae and Semen armeniacae amarum. The prescriptions treating dyspnoea often used double herb group of Herba ephedrae & Radix glycyrrhizae, while prescriptions treating sputum often used double herb group of Rhizoma pinelliae & Radix glycyrrhizae and Rhizoma pinelliae & Semen armeniacae amarum, triple herb groups of Rhizoma pinelliae & Semen armeniacae amarum & Radix glycyrrhizae and Pericarpium citri reticulatae & Rhizoma pinelliae & Radix glycyrrhizae. CONCLUSIONS: The prescriptions treating respiratory disease showed common compatibility laws in using herbs and special compatibility laws for treating different respiratory symptoms. These principle patterns and special compatibility laws reported here could be useful for doctors to choose correct herbs and prescriptions in treating respiratory disease.

Effects of Radix aconiti lateralis preparata and Rhizoma zingiberis on energy metabolism and expression of the genes related to metabolism in rats.

OBJECTIVE: To study the influence of Radix aconiti lateralis preparata and Rhizoma zingiberis, two species of Chinese medicinal herbs with hot property, on energy metabolism and gene expression spectrum, and to analyze the possible mechanism of their effects. METHODS: Forty-eight specific pathogen free Wistar rats were randomly divided into a Radix aconiti lateralis preparata group, a Rhizoma zingiberis group, and a control group. They were intragastrically treated with concentrated decoction of Radix aconiti lateralis preparata, Rhizoma zingiberis and normal saline respectively for 20 days. Toe temperature (TT), energy intake (EI), digestible energy (DE), and metabolizable energy (ME) were measured. The content of adenosine triphosphate (ATP) and energy charge (EC) in hepatic tissue were measured with high performance liquid chromatography (HPLC). The activity of ATPase and succinate dehydrogenase (SDH) in the liver were detected with chemical colorimetry. The gene expression in the liver was detected with Illumina's rat Ref-12 gene array. The differential expression genes were selected, annotated and classified based on Gene Ontology (GO). Real-time quantitative reverse-transcriptase PCR (Q-RT-PCR) was used to test the accuracy of results. RESULTS: Compared with the control group, the TT on the 10(th) day after the beginning of administration and ATP in the Radix aconiti lateralis preparata and Rhizoma zingiberis groups increased significantly (P<0.05). EI/body mass (BM), DE/BM, ME/BM, the hepatic EC and the activity of Na(+)-K(+)-ATPase, Ca(2+)-Mg(2+)-ATPase and SDH of liver increased significantly only in the Radix aconiti lateralis preparata group (P<0.05). There were 592 differential expression genes in the Radix aconiti lateralis preparata group and 1 159 in the Rhizoma zingiberis group compared with the control group. Among the differential expression genes, genes related to metabolic processes were the most significant based on GO analysis. There were 337 strips of gene differential expression in common in both Radix aconiti lateralis preparata and Rhizoma zingiberis groups compared with the control group. CONCLUSIONS: Herbs with hot property such as Radix aconiti lateralis preparata and Rhizoma zingiberis could improve the energy metabolism in rats, through influencing the metabolic process of sugar, lipid, and amino acid. It could also promote the production, storage, and utilization of energy by regulating the gene expression related to metabolism, which may be the main molecular mechanism of warming yang and dispelling cold for the treatment of the cold syndrome according to Chinese medicine theory.

[Elementary exploration of the origin and development of marine Chinese materia medica].

According to archaeological discoveries, humans began to make use of marine natural resources early in the Palaeolithic era. In the Spring and Autumn period and Warring States period, they began to use marine life as medicines and also had simple cognitions on their efficacy and processing. In the Qin and Han dynasties, people further deepened the understanding of the marine Chinese materia medica and created prescriptions making use of marine drugs. In the Tang and Song period, the number of marine Chinese materia medica species and corresponding prescriptions apparently increased. The cognitions of the property, flavor, efficacy as well as the compatible principle of marine Chinese materia medica was further deepened and the scope of their treatment also significantly expanded. In the Ming and Qing dynasties, the cognition of the marine Chinese materia medica was mainly the conclusions of the previous experience. After the founding of the People's Republic of China (PRC), with the development of science and technologies, the ability of exploiting and utilizing the marine Chinese materia medica by people dramatically increased, and the species of marine Chinese materia medica reached more than one thousand. However, the development of marine Chinese materia medica is confronted with new problems; although the number of species of marine Chinese materia medica increased, the understanding of their property and flavor is obviously lagging behind, which seriously affects the clinical application of marine Chinese materia medica.
