Pinellia ternata

ETHNOPHARMACOLOGICAL RELEVANCE: Chinese herbal medicine is increasingly used as complementary therapy to manage nausea and vomiting in different cultures. One such herbal recipe is the Hezhong granules, which contain classical antiemetic formulations, and are commonly used to prevent chemotherapy-induced nausea and vomiting (CINV). Modern pharmacological studies have shown that the key components of Hezhong granules, including Pinellia ternata (Thunb.), Evodia rutaecarpa (Juss.), and Zingiber officinale exhibit significant antiemetic and antitumor properties. Despite this promising evidence, controlling CINV remains a significant challenge in cancer treatment. Moreover, there is a lack of scientifically designed clinical trials to validate the efficacy and safety of classical antiemetic formulas for CINV interventions. AIMS OF THE STUDY: To investigate the efficacy and safety of Hezhong granules in preventing CINV in patients with advanced colorectal cancer (CRC). METHODS: This study was conducted between October 2020 and February 2022 in 12 hospital wards in Southwest China. In this multicenter, randomized controlled trial, we enrolled patients with advanced CRC who received fluorouracil-based chemotherapy. The patients were randomly assigned in a 1:1 ratio to either the Hezhong granule group (receiving a 5-HT3-receptor antagonist, dexamethasone, and Hezhong granules) or the placebo group (receiving a 5-HT3-receptor antagonist, dexamethasone, and placebo) during the first and second courses of chemotherapy. A 5-day diary was provided to all patients. Acute and delayed CINV were defined as CINV occurring within 24 h or between 24 and 120 h after the start of treatment. The primary endpoints were complete response rate (CRR, defined as the proportion of patients without nausea/vomiting) and objective response rate (ORR, defined as the proportion of patients without nausea/vomiting plus mild nausea/vomiting) for both acute and delayed CINV. Secondary endpoints were the daily rates of CINV events and Functional Living Index-Emesis (FLIE). To identify the predictors of CINV, we conducted multivariate ordered logistic regression analysis. This study was registered wi

ETHNOPHARMACOLOGICAL RELEVANCE: The combination of Aconitum carmichaelii Debx (Chuanwu, CW) and Pinellia ternata (Thunb.) Breit (Banxia, BX) forms an herbal pair within the eighteen incompatible medicaments (EIM), indicating that BX and CW are incompatible. However, the scientific understanding of this incompatibility mechanism, especially the corresponding drug-drug interaction (DDI), remains complex and unclear. AIM OF THE STUDY: This study aims to explain the DDI and potential incompatibility mechanism between CW and BX based on pharmacokinetics and cocktail approach. MATERIALS AND METHODS: Ultraperformance liquid chromatography-tandem mass spectrometry methods were established for pharmacokinetics and cocktail studies. To explore the DDI between BX and CW, in the pharmacokinetics study, 10 compounds were determined in rat plasma after administering CW and BX-CW herbal pair extracts. In the cocktail assay, the pharmacokinetic parameters of five probe substrates were utilized to assess the influence of BX on cytochrome P450 (CYP) isoenzyme (dapsone for CYP3A4, phenacetin for CYP1A2, dextromethorphan for CYP2D6, tolbutamide for CYP2C9, and omeprazole for CYP2C19). Finally, the DDI and incompatibility mechanism of CW and BX were integrated to explain the rationality of EIM theory. RESULTS: BX not only enhances the absorption of aconitine and benzoylaconine but also accelerates the metabolism of mesaconitine, benzoylmesaconine, songorine, and fuziline. Moreover, BX affects the activity of CYP enzymes, which regulate the metabolism of toxic compounds. CONCLUSIONS: BX altered the activity of CYP enzymes, consequently affecting the metabolism of toxic compounds from CW. This incompatibility mechanism may be related to the increased absorption of these toxic compounds in vivo.

136. Zhongguo Zhong Yao Za Zhi. 2015 Sep;40(18):3630-5. [Antagonistic effect of gingerols against TNF-α release, ROS overproduction and RIP3 expression increase induced by lectin from Pinellia ternata]. [Article in Chinese] Yu HL, Mao SH, Zhao TF, Wu H, Pan YZ, Shu CY. To explore the antagonistic effect of gingerols against the inflammation induced by lectin from Pinellia ternata. In this study, ELISA method was used to determine the effect of different extracts from gingerols on the release of inflammatory factor TNF-α from macrophages induced by lectin from P. ternata. The fluorescence probe was used to determine the effect of gingerols on the changes in ROS of macrophages induced by lectin from P. ternata. The western-blot method was applied to study the effect of gingerols on the increase in expression of cell receptor interacting protein RIP3 in macrophages induced by lectin from P. ternata. The scanning electron microscope (SEM) was used to study the effect of gingerols on morphological changes in macrophages induced by lectin from P. ternata. According to the results, gingerols can significantly inhibit the release of inflammatory factor from macrophages induced by lectin from P. ternata, ROS overproduction and increase in RIP3 expression. SEM results showed that gingerols can inhibit the cytomorphosis and necrocytosis induced by lectin from P. ternata. Fresh ginger's detoxication may be related to gingerols' effects in inhibiing release of inflammatory factor, ROS overproduction and increase in RIP3 expression caused by macrophages induced by lectin from P. ternata, which are mainly inflammatory development.

BACKGROUND: Traditional Chinese medicine (TCM) herbal formulae provide valuable therapeutic strategies. However, the active ingredients and mechanisms of action remain unclear for most of these formulae. Therefore, the identification of complex mechanisms is a major challenge in TCM research. METHODS: This study used a network pharmacology approach to clarify the anti-inflammatory and cough suppressing mechanisms of the Chinese medicinal preparation Eriobotrya japonica - Fritillaria usuriensis dropping pills (ChuanbeiPipa dropping pills, CBPP). The chemical constituents of CBPP were identified by high-quality ultra-performance liquid chromatography/quadrupole time-of-flight mass spectrometry (UPLC/Q-TOF-MS), and anti-inflammatory ingredients were selected and analyzed using the PharmMapper and Kyoto Encyclopedia of Genes and Genomes (KEGG) bioinformatics websites to predict the target proteins and related pathways, respectively. Then, an RNA-sequencing (RNA-Seq) analysis was carried out to investigate the different expression of genes in the lung tissue of rats with chronic bronchitis. RESULTS: Six main constituents affected 19 predicted pathways, including ursolic acid and oleanolic acid from Eriobotrya japonica (Thunb.) Lindl. (Eri), peiminine from Fritillaria usuriensis Maxim. (Fri), platycodigenin and polygalacic acid from Platycodon grandiflorum (Jacq.) A. DC. (Pla) and guanosine from Pinellia ternata (Thunb.) Makino. (Pin). Expression of 34 genes was significantly decreased after CBPP treatment, affecting four therapeutic functions: immunoregulation, anti-inflammation, collagen formation and muscle contraction. CONCLUSION: The active components acted on the mitogen activated protein kinase (MAPK) pathway, transforming growth factor (TGF)-beta pathway, focal adhesion, tight junctions and the action cytoskeleton to exert anti-inflammatory effects, resolve phlegm, and relieve cough. This novel approach of global chemomics-integrated systems biology represents an effective and accurate strategy for the study of TCM with multiple components and multiple target mechanisms.

OBJECTIVE: Elucidating the detoxification mechanism of the raw Pinellia ternata processed by alum solution or alkaline solution (pH > 12). METHOD: Raw Pinellia ternata was immersed in alum solution and alkaline solution according to Chinese pharmacopoeia. Observed the shape's changing of needle-like calcium oxalate crystals by scanning electro-microscopy. Determinating the contents of calcium oxalate crystals by applying oxidation reduction titration. Measured the irritations of raw P. ternata and various processing products on the model of rabbits'eyes. RESULT: After processed by 8% alum solution prescribed in Chinese pharmacopoeia or 10% sodium carbonate solution, the needle-like shape of raphides in raw Pinellia ternata were changing and the sting barb of raphides were rusted and dissolved, the contents of calcium oxalate crystal in raw Pinellia ternata were sharply declined from more than 1% to less than 0.5%. the decline of contents is relative to the irritation decline of P. ternata on rabbit's eyes. Less than 0.5% calcium oxalate crystals of P. ternata almost had no irritation. CONCLUSION: After processed by 8% alum solution or sodium carbonate solution (pH > 12) , the irritation components in raw P. ternata could be rusted and dissolved, the needle point of raphides was broken, which led to the raphides'content declining and the irritation disappearing. The micro-structures, shapes and contents of calcium oxalate crystals in different medicine plants were not same. These properties of calcium oxalate crystal in India Madder Root and yam et al were very different from those in raw P. ternata.

Pinelliae Rhizoma (PR), known as Banxia in Chinese, Hange in Japanese, and Banha in Korean, is a renowned herbal medicine in East Asia derived from the dry tuber of Pinellia ternata (Thunb.) Breit. (PT). It is extensively utilized in dispensing granules, classical prescriptions, and herbal formulas to treat various conditions, including cough, infection, phlegm, nausea, asthma, and inflammation. Despite numerous studies on PR and its classical prescriptions over recent decades, a comprehensive synthesis of available evidence regarding its multifunctional roles and therapeutic potential is lacking. This review aims to address this gap by examining emerging evidence from metabonomics, preclinical studies, and clinical trials, while exploring potential trends and prospects for future research. A systematic literature search was conducted across six electronic databases, including PubMed, Web of Science, Scopus, ScienceDirect, Wanfang, and China National Knowledge Infrastructure, to identify relevant articles on PR published until March 2023. PR contains 107 compounds with diverse pharmacological activities, including anti-inflammatory, immune regulatory, anti-viral, anti-cancer, anti-asthma, antitussive and expectorant, antioxidant, anti-obesity, anti-atherosclerosis, anti-microbial, emetic and anti-emetic, anti-convulsant and anti-epileptic, sedative and hypnotic, learning and memory enhancement, and anti-depressant effects. Metabonomic studies suggest that raw PR may exhibit cardiotoxicity and pregnancy toxicity while showing no apparent hepatorenal toxicity. However, limited pharmacokinetic investigations on PR constrain its clinical translation. Furthermore, clinical safety data on PR is scarce, with only four clinical trials assessing its positive effects in pediatric epilepsy, nausea and vomiting, soft tissue injury, and chronic sinus tract. This review aims to enhance understanding of PR and provide valuable information and recommendations for further research and development of herbal medicine.

PURPOSE: The aim of this study is to determine the effectiveness and reliability of adding traditional Chinese medicine (TCM) in the clinical intervention and explore mechanisms of action for chronic atrophic gastritis (CAG) through meta- and network pharmacology analysis (NPAs). METHODS: A predefined search strategy was used to retrieve literature from PubMed, Embase database, Cochrane Library, China National Knowledge Infrastructure (CNKI), Chinese BioMedical Literature Database (CBM), Wan Fang Data and China Science and Technology Journal Database (VIP). After applying inclusion and exclusion criteria, a total of 12 randomized controlled trials (RCTs) were included for meta-analysis to provide clinical evidence of the intervention effects. A network meta-analysis using Bayesian networks was conducted to observe the relative effects of different intervention measures and possible ranking of effects. The composition of the TCM formulation in the experimental group was analysed, and association rule mining was performed to identify hub herbal medicines. Target genes for CAG were searched in GeneCards, Online Mendelian Inheritance in Man, PharmGKB, Therapeutic Target Database and DrugBank. A regulatory network was constructed to connect the target genes with active ingredients of the hub herbal medicines. Enrichment analyses were performed using the Gene Ontology (GO) and the Kyoto Encyclopedia of Genes and Genomes (KEGG) to examine the central targets from a comprehensive viewpoint. Protein-protein interaction networks (PPINs) were constructed to identify hub genes and conduct molecular docking with differentially expressed genes (DEGs) and corresponding active molecules. RESULTS: A total of 1140 participants from 12 RCTs were included in the statistical analysis, confirming that the experimental group receiving the addition of TCM intervention had better clinical efficacy. Seven hub TCMs (Paeonia lactiflora, Atractylodes macrocephala, Pinellia ternata, Citrus reticulata, Codonopsis pilosula, Salvia miltiorrhiza and Coptis chinensis) were identified through association rule analysis of all included TCMs. Thirteen hub genes (CDKN1A, CASP3, STAT1, TP53, JUN, MAPK1

BACKGROUND: Pinellia ternata (P. ternata, Banxia)-containing traditional Chinese medicine (TCM) is widely used in China as an adjuvant treatment for chemotherapy-induced nausea and vomiting (CINV). However, evidence of its efficacy and safety remains limited. PURPOSE: To investigate the efficacy and safety of P. ternata-containing TCM combined with 5-hydroxytryptamine-3 receptor antagonists (5-HT3RAs) in the treatment of CINV. STUDY DESIGN: Systematic review and meta-analysis of randomized controlled trials (RCTs). METHODS: All relevant RCTs were systematically retrieved from seven internet databases (up to February 10, 2023). P. ternata-containing TCM combined with 5-HT3RAs to treat CINV was included in all RCTs. The clinical effective rate (CER) was defined as the primary outcome, while appetite, quality of life (QOL), and side effects were secondary outcomes. RESULTS: The meta-analysis included 22 RCTs with 1,787 patients. Our results indicated that P. ternata-containing TCM combined with 5-HT3RAs significantly improved the CER of CINV (RR = 1.46, 95% CI = 1.37-1.57, p < 0.00001), appetite (RR = 1.77, 95% CI = 1.42-2.20, p < 0.00001), QOL (RR = 7.67, 95% CI = 1.56-13.78, p = 0.01), the CER of several 5-HT3RA medications (RR = 1.47, 95% CI = 1.37-1.57, p < 0.00001), and acute and delayed vomiting (RR = 1.23, 95% CI = 1.12-1.36, p < 0.0001) compared with the 5-HT3RAs alone, while the combination therapy decreased the incidence of side effects induced by 5-HT3RAs for CINV (RR = 0.50, 95% CI = 0.42-0.59, p < 0.00001). CONCLUSION: According to the findings of this systematic review and meta-analysis, P. ternata-containing TCM combined with 5-HT3RAs was safer and more effective than 5-HT3RAs alone for CINV patients. However, due to the limitations of the included studies, more high-quality clinical trials are required to further validate our findings.

The dried tuber of Pinellia ternata (Thunb.) Breit, Pinelliae Rhizoma (PR, also named 'Banxia' in Chinese), is widely used in traditional medicine. This review aims to provide detail summary of active ingredients, pharmacological effects, toxic ingredients, detoxification strategies, and omic researches, etc. Pharmacological ingredients from PR are mainly classified into six categories: alkaloids, amino acids, polysaccharides, phenylpropanoids, essential oils, and glucocerebrosides. Diversity of chemical composition determines the broad-spectrum efficacy and gives a foundation for the comprehensive utilization of P. ternata germplasm resources. The pharmacological compounds are involved in inhibition of cancer cells by targeting various pathways, including activation of immune system, inhibition of proliferation and cycle, induction of apoptosis, and inhibition of angiogenesis. The pharmacological components of PR act on nervous system by targeting neurotransmitters, activating immune system, decreasing apoptosis, and increasing redox system. Lectins, one major class of the toxic ingredients extracted from raw PR, possess significant toxic effects on human cells. Inflammatory factors, cytochrome P450 proteins (CYP) family enzymes, mammalian target of rapamycin (mTOR) signaling factors, transforming growth factor-β (TGF-β) signaling factors, and nervous system, are considered to be the target sites of lectins. Recently, omic analysis is widely applied in Pinellia genus studies. Plastome genome-based molecular markers are deeply used for identifying and resolving phylogeny of Pinellia genus plants. Various omic works revealed and functional identified a series of environmental stress responsive factors and active component biosynthesis-related genes. Our review summarizes the recent progress in active and toxic ingredient evaluation, pharmacological effects, detoxification strategies, and functional gene identification and accelerates efficient utilization of this traditional herb.

OBJECTIVE: The use of traditional Chinese medicine (TCM) in stroke is increasing worldwide. Here we report the existing clinical evidence of the Pinellia Ternata containing formula Wen Dan Decoction (WDD) for the treatment of ischemic stroke and hemorrhagic stroke. METHODS: PubMed, CNKI, Wan Fang database, Cochrane Library and online Clinical Trial Registry were searched up to 26 February 2013 for randomized, controlled clinical trials (RCTs) using WDD as intervention versus Western conventional medicine as control to treat stroke. Clinical outcomes were improvement of the Neurological Functional Deficit Scores (NFDS) and overall therapeutic efficacy rates including rate of cure. Meta-regression analysis using Hedges'g was performed for RCTs with significant heterogeneity. RESULTS: A total of 22 RCTs of ischemic stroke and 4 RCTs of hemorrhagic stroke, involving 2214 patients (1167 used WDD), met our inclusion criteria. Meta-analysis of the 13 RCTs reporting NFDS improvement favored WDD over the control (mean difference=-3.40, 95% confidence intervals [CI]=[-4.64, -2.15]). Rate of overall therapeutic efficacy (odds ratio [OR]=3.39, 95%CI=[1.81, 6.37]) for hemorrhagic stroke were significantly higher in WDD treated patients than the control subjects. In the 1898 patients with ischemic stroke, WDD medication also achieved higher rates of cure (OR=2.22, 95%CI=[1.66, 2.97]) and overall therapeutic efficacy (OR=3.31, 95%CI=[2.54, 4.31]) than the conventional treatment. CONCLUSIONS: WDD displays benefits on improvement of neurological function and overall therapeutic efficacy in post-stroke patients. TCM such as WDD may serve as a therapeutic tool of dual actions to explore the common mechanisms underlying cerebral hemorrhage and ischemia.
