[PMID: 33486266 DOI: 10.1016/j.phymed.2021.153459] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/22/2020] [Revised: 12/17/2020] [Accepted: 01/01/2021] [Indexed: 06/12/2023]
Abstract
BACKGROUND There is growing interest in using herbal supplements to treat constipation; however, little evidence exists for their use. PURPOSE This study evaluates the efficacy and safety of herbal formula MaZiRenWan (Hemp Seed Pill, HSP) in patients with functional or non-functional constipation. STUDY DESIGN Systematic review and meta-analysis METHODS: PubMed, CENTRAL, Embase, CNKI, and Wanfang were searched through April 20, 2020 for randomized trials of HSP versus placebo or medications for all types of constipation. The primary outcomes were complete response rate, complete spontaneous bowel movement (CSBM), patient-reported satisfactory treatment rate (prSTR), and adverse events (AEs). Clinical data were analyzed using a random-effects model, and the quality of evidence was evaluated with the GRADE system. RESULTS This review includes 1681 constipation patients from 17 moderate-to-high risk of bias trials that were conducted in east Asia. Two high-quality trials showed that HSP compared with placebo significantly increased weekly CSBM (mean difference, 0.95; 95% CI: 0.56, 1.35) and had a higher complete response rate (risk ratio [RR], 1.43; 95% CI: 1.20, 1.71) in patients with functional constipation. Low-quality evidence showed significant improvement in prSTR in HSP compared with conventional medications (RR, 1.79; 95% CI: 1.42, 2.25). Additionally, HSP use did not increase AEs compared with no HSP (p = 0.99). CONCLUSIONS This study found that HSP was effective among Asian patients with functional constipation. Rigorous trials need to be conducted in clinical populations outside of east Asia and in those with non-functional constipation to increase the generalizability of the evidence.

Abstract
Introduction: Increasing life expectancy in women and having menstrual problems and hormone-associated complications have led people to use complementary and alternative medicine. In menopause, the reduction in estrogen and androgen physiologically leads to a decrease in blood flow in the volvuleous and vaginal zone, resulting in a reduction in sexual desire and arousal. Sexual satisfaction plays an important role in mental health. The aim of this study was to investigate the effect of Tribulus terrestris on sexual satisfaction in postmenopausal women. Methods: This double-blind clinical trial was conducted in 2017 with the aim of investigating the effect of hydro-alcohol extract of T. terrestris on sexual satisfaction of postmenopausal women on 60 women referred to health center number 1 in eastern Ahvaz. A total of 60 postmenopausal women were randomly assigned into two groups of 30 to receive a syrup containing T. terrestris extract at a concentration of 0.9 mg and placebo for 8 weeks. Sexual satisfaction was calculated based on Larsson questionnaire. Data were analyzed by SPSS software (version 22) and t-test was used for comparing two groups in quantitative variables and Chi-square test was used for qualitative variables. P value less than 0.05 was considered significant. Findings: After intervention, the mean of sexual satisfaction in the intervention group was significantly higher than in the preintervention group (P < 0.005), and a significant increase in sexual satisfaction was observed in the tetanus syrup group. Results: Taking T. terrestris syrup increased sexual satisfaction in postmenopausal women.

Identification of Steroidogenic Components Derived From Gardenia jasminoides Ellis Potentially Useful for Treating Postmenopausal Syndrome. Front Pharmacol 2018; 9:390. [PMID: 29899696 PMCID: PMC5989419 DOI: 10.3389/fphar.2018.00390] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2017] [Accepted: 04/04/2018] [Indexed: 12/11/2022] Open
Abstract
Estrogen-stimulating principles have been demonstrated to relieve postmenopausal syndrome effectively. Gardenia jasminoides Ellis (GJE) is an herbal medicine possessing multiple pharmacological effects on human health with low toxicity. However, the therapeutic effects of GJE on the management of postmenopausal syndrome and its mechanism of action have not been fully elucidated. In this study, network pharmacology-based approaches were employed to examine steroidogenesis under the influence of GJE. In addition, the possibility of toxicity of GJE was ruled out and four probable active compounds were predicted. In parallel, a chromatographic fraction of GJE with estrogen-stimulating effect was identified and nine major compounds were isolated from this active fraction. Among the nine compounds, four of them were identified by network pharmacology, validating the use of network pharmacology to predict active compounds. Then the phenotypic approaches were utilized to verify that rutin, chlorogenic acid (CGA) and geniposidic acid (GA) exerted an estrogen-stimulating effect on ovarian granulosa cells. Furthermore, the results of target-based approaches indicated that rutin, CGA, and GA could up-regulate the FSHR-aromatase pathway in ovarian granulosa cells. The stimulation of estrogen production by rat ovarian granulosa cells under the influence of the three compounds underwent a decline when the follicle-stimulating hormone receptor (FSHR) was blocked by antibodies against the receptor, indicating the involvement of FSHR in the estradiol-stimulating activity of the three compounds. The effects of the three compounds on estrogen biosynthesis- related gene expression level were further confirmed by Western blot assay. Importantly, the MTT results showed that exposure of breast cancer cells to the three compounds resulted in reduction of cell viability, demonstrating the cytotoxicity of the three compounds. Collectively, rutin, chlorogenic acid and geniposidic acid may contribute to the therapeutic potential of GJE for the treatment of postmenopausal syndrome.

JOURNAL OF ETHNOPHARMACOLOGY 2018; 216:274-282. [PMID: 29366767 DOI: 10.1016/j.jep.2018.01.020] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/25/2017] [Revised: 12/11/2017] [Accepted: 01/17/2018] [Indexed: 06/07/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Previous studies had indicated that hormone therapy (HT) may increase the risk of ischemic stroke (IS) in menopausal women. However, little is known about the benefits and risks of use of Chinese herbal medicine (CHM) in conditions related to hormone use. The aim of this study is to explore the risk of IS in menopausal women treated with HT and CHM. MATERIALS AND METHODS A total of 32,441 menopausal women without surgical menopause aged 40-65 years were selected from 2003 to 2010 using the 2-million random samples of the National Health Insurance Research Database in Taiwan. According to the medication usage of HT and CHM, we divided the current and recent users into two groups: an HT use-only group (n = 4989) and an HT/CHM group (n = 9265). Propensity-score matching samples (4079 pairs) were further created to deal with confounding by indication. The adjusted hazard ratios (HR) of IS were estimated by the robust Cox proportional hazards model. RESULTS The incidence rate of IS in the HT/CHM group was significantly lower than in the HT group (4.5 vs. 12.8 per 1000 person-year, p < 0.001). Multivariate analysis results indicated that additional CHM use had a lower risk of IS compared to the HT group (HR = 0.3; 95% confidence interval [CI], 0.21-0.43). Further subgroup analyses and sensitivity analyses had similar findings. CONCLUSION We found that combined use of HT and CHM was associated with a lower risk of IS. Further study is needed to examine possible mechanism underlying this association.

Abstract
OBJECTIVE Chinese herbal products (CHPs) are widely used for atrial fibrillation (AF) in Taiwan. We investigated the effect of adjuvant CHPs in preventing ischemic stroke in patients with AF. METHODS Taiwanese patients in the Health Insurance Database newly diagnosed with AF during 2000-2011 were enrolled. Medication treatment with/without CHPs was administered within 7 days after the AF diagnosis. The clinical endpoint was an ischemic stroke. The Chi-square test, Fisher's exact test, and Student t test were used to examine differences between the traditional Chinese medicine (TCM) and non-TCM cohorts. Cox proportional hazard regression was used to assess the risk for ischemic stroke between two cohorts. RESULTS Three hundred and eleven patients underwent TCM treatment and 1715 patients did not. Compared to non-TCM users, TCM users had a lower incidence of stroke (12.59% vs. 1.93%, respectively) and lower risk of stroke [CHA2DS2-VASc score = 0-2 (hazard ratio = 0.20; 95% confidence interval = 0.06-0.65)]. Compared to non-TCM users, the stroke risk was significantly lower in TCM users with AF who were female or younger than 65 years, but not in males, people more than 65 years old, or people with comorbidities. Compared to TCM users, non-TCM users who received conventional treatment had a higher ischemic stroke risk. The risk for AF-related hospitalization was significantly lower in TCM users (0.64%) than in non-TCM users (38.1%). CONCLUSIONS Users of TCM with AF have a lower risk of new-onset ischemic stroke. Therefore, adjuvant CHP therapy may have a protective effect and may be used in AF patients to prevent ischemic stroke.

Abstract
BACKGROUND Chinese herbal medicine (CHM) usage is expected to increase as women suffering from menopausal symptoms are seeking alternative therapy due to concerns from the adverse effects (AEs) associated with hormone therapy (HT). Scientific evidence for their effectiveness and safety is needed. OBJECTIVES To evaluate the effectiveness and safety of CHM in the treatment of menopausal symptoms. SEARCH METHODS We searched the Gynaecology and Fertility Group's Specialised Register of controlled trials, Cochrane Central Register of Controlled Trials (CENTRAL; 2015, Issue 3), MEDLINE, Embase, CINAHL, AMED, and PsycINFO (from inception to March 2015). Others included Current Control Trials, Citation Indexes, conference abstracts in the ISI Web of Knowledge, LILACS database, PubMed, OpenSIGLE database, and China National Knowledge Infrastructure database (CNKI, 1999 to 2015). Other resources included reference lists of articles as well as direct contact with authors. SELECTION CRITERIA Randomised controlled trials (RCTs) comparing the effectiveness of CHM with placebo, HT, pharmaceutical drugs, acupuncture, or another CHM formula in women over 18 years of age, and suffering from menopausal symptoms. DATA COLLECTION AND ANALYSIS Two review authors independently assessed 864 studies for eligibility. Data extractions were performed by them with disagreements resolved through group discussion and clarification of data or direct contact with the study authors. Data analyses were performed in accordance with Cochrane Collaboration guidelines. MAIN RESULTS We included 22 RCTs (2902 women). Participants were from different ethnic backgrounds with the majority of Chinese origin.When CHM was compared with placebo (eight RCTs), there was little or no evidence of a difference between the groups for the following pooled outcomes: hot flushes per day (MD 0.00, 95% CI -0.88 to 0.89; 2 trials, 199 women; moderate quality evidence); hot flushes per day assessed by an overall hot flush score in which a difference of one point equates to one mild hot flush per day (MD -0.81 points, 95% CI -2.08 to 0.45; 3 RCTs, 263 women; low quality evidence); and overall vasomotor symptoms per month measured by the Menopause-Specific Quality of Life questionnaire (MENQOL, scale 0 to 6) (MD -0.42 points; 95% CI -1.52 to 0.68; 3 RCTs, 256 women; low quality evidence).In addition, results from individual studies suggested there was no evidence of a difference between the groups for daily hot flushes assessed by severity (MD -0.70 points, 95% CI -1.00, -0.40; 1 RCT, 108 women; moderate quality evidence); or overall monthly hot flushes scores (MD -2.80 points, 95% CI -8.93 to 3.33; 1 RCT, 84 women; very low quality evidence); or overall daily night sweats scores (MD 0.07 points, 95% CI -0.19 to 0.33, 1 RCT, 64 women; low quality evidence); or overall monthly night sweats scores (MD 1.30 points, 95% CI -1.76 to 4.36, 1 RCT, 84 women; very low quality evidence). However one study using the Kupperman Index reported that overall monthly vasomotor symptom scores were lower in the CHM group (MD -4.79 points, 95% CI -5.52 to -4.06; 1 RCT, 69 women; low quality evidence).When CHM was compared with hormone therapy (HT) (10 RCTs), only two RCTs reported monthly vasomotor symptoms using MENQOL. It was uncertain whether CHM reduces vasomotor symptoms (MD 0.47 points, 95% CI -0.50 to 1.44; 2 RCTs, 127 women; very low quality evidence).Adverse effects were not fully reported in the included studies. Adverse events reported by women taking CHM included mild diarrhoea, breast tenderness, gastric discomfort and an unpleasant taste. Effects were inconclusive because of imprecise estimates of effects: CHM versus placebo (RR 1.51; 95% CI 0.69 to 3.33; 7 trials, 705 women; I² = 40%); CHM versus HT (RR 0.96; 95% CI 0.66 to 1.39; 2 RCTs, 864 women; I² = 0%); and CHM versus specific conventional medications (such as Fluoxetine and Estazolam) (RR 0.20; 95% CI 0.03 to 1.17; 2 RCTs, 139 women; I² = 61%). AUTHORS' CONCLUSIONS We found insufficient evidence that Chinese herbal medicines were any more or less effective than placebo or HT for the relief of vasomotor symptoms. Effects on safety were inconclusive. The quality of the evidence ranged from very low to moderate; there is a need for well-designed randomised controlled studies.

Abstract
OBJECTIVES To provide the first critical review of traditional Chinese medicine (TCM) use amongst symptomatic menopausal women, drawing upon work examining the perspectives of both TCM users and TCM practitioners. METHODS A search was conducted in three English-language databases (MEDLINE, CINAHL and AMED) and three Chinese-language databases (CNKI, VIP and CBM Disc) for 2002-2013 international peer-reviewed articles reporting empirical findings of TCM use in menopause. RESULTS A total of 25 journal articles reporting 22 studies were identified as meeting the review inclusion criteria. Chinese herbal medicine appears to be the most common therapy amongst symptomatic menopausal women, and vasomotor symptoms and emotional changes are the most frequent symptoms for which TCM is sought. However, evidence regarding the prevalence of TCM use and users' profile in menopause is limited. Existing studies are of varied methodological quality, often reporting low response rate, extensive recall bias and a lack of syndrome differentiation. CONCLUSIONS This review provides insights for practitioners and health policy-makers regarding TCM care to symptomatic menopausal women. More nationally representative studies are required to rigorously examine TCM use for the management of menopausal symptoms. Syndrome differentiation of menopausal women is an area which also warrants further attention.

Abstract
Studies on in vitro bioaccessibility and safety assessment of 6 elements namely Fe, Zn, Cu, Mn, As and Cd in decoction of eight commonly consumed "Zhebawei" herbal medicines were carried out. The method was based on simulation of human digestion in the gastrointestinal tract. Total content and content in extracts from gastrointestinal phases were analyzed for these elements by inductively coupled plasma atomic emission spectrometer (ICP-AES). In decoction of all 8 herbal medicines, it was found that the total content and bioaccessible concentration of these elements varied considerably among the types of herb, and the total content of each element did not show linearity with their bioaccessible content of the corresponding element. There is no risk of adverse health effects resulting from overdose of Fe, Zn, Cu, and Mn for almost all individuals by ingesting recommended maximum daily dose of these eight herbal medicines. In terms of Cd only Ophitopogin japonicum had higher total concentration and bioaccessible content than the value of suggested limit (5.4μg/d). For total As content, only Scrophularia ningpoensis and Corydalis yanhusuo did not meet the safety standard. However, regarding bioaccessible As contents, none of the eight herbal medicines exceeded the value of the daily permissible intake of As (0.12mg). The risk of toxicity from an element in herbal medicine might be overestimated when the total concentration but not the bioaccessible content is taken into account. In vitro digestion method is rapid, relatively simple and inexpensive, which could be helpful in conducting experiments about safety assessment of an element in herbal medicines.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Leonurus japonicus Houtt. (Labiatae), commonly called Chinese motherwort ([Symbol: see text]), is an herbaceous flowering plant native to Asia. For thousands of years in China, the aerial part of Leonurus japonicus has been used to treat menoxenia, dysmenorrhea, amenorrhea, lochia, edema of the body, oliguresis, sores, ulcerations and other diseases in women. Now, Leonurus japonicus is listed in the Pharmacopoeia of the People's Republic of China. The present paper reviewed the ethnopharmacology, phytochemistry, biological actions and toxicology of Leonurus japonicus. MATERIALS AND METHODS Information on Leonurus japonicus was gathered via the Internet (using Elsevier, ACS, Medline Plus, CNKI, VIP, Web of Science, Google Scholar and Baidu Scholar) and libraries. RESULTS Approximately 140 chemical compounds have been isolated from Leonurus japonicus, and the major components have been determined to be alkaloids, diterpenes and flavones. Among these active compounds, the effects of leonurine and stachydrine have been widely investigated. The primary active components in Leonurus japonicus possess wide pharmacological actions, such as effects on the uterus as well as cardioprotective, anti-oxidative, neuroprotective and anti-cancer activities. CONCLUSIONS Modern pharmacological studies have demonstrated that Leonurus japonicus has marked bioactivities, especially on the uterus and as a cardioprotective agent. These activities are related to its traditional use and provide prospects for the development of novel drugs, therapeutics and health care products for women. However, the toxicity of Leonurus japonicus will require further study, and the nomenclature for Leonurus japonicus will require additional clarification.

Abstract
OBJECTIVE This study is a phase II clinical trial that aims to investigate the dose-response relationship of a Chinese herbal medicine preparation, Dang Gui Buxue Tang (DBT), with short-term menopausal symptoms and quality of life in local postmenopausal women. METHODS A randomized, double-blind, multiple-dose escalation trial was performed in 60 postmenopausal women experiencing severe hot flashes and night sweats. The participants were randomized to receive DBT preparations at 1.5, 3.0, or 6.0 g/day for 12 weeks. The primary outcomes were vasomotor symptoms, Greene Climacteric Scale (GCS) score, and Menopause-Specific Quality of Life (MENQOL) score. Secondary outcomes included serum hormones and lipids. RESULTS There were between-group differences in psychological/psychosocial (P = 0.015, GCS; P = 0.013, MENQOL) and somatic/physical (P = 0.019, GCS; P = 0.037, MENQOL) domains, and improvement was significantly greatest (P < 0.05) in the 6.0 g/day dose group. The frequency and severity of hot flashes and night sweats were significantly reduced in the 3.0 g/day (14.5%-21.2%, P < 0.05, hot flashes; 28.6%-39.6%, P < 0.05, night sweats) and 6.0 g/day (34.9%-37.4.0%, P < 0.01, hot flashes; 10.1%-12.8%, P < 0.01, night sweats) dose groups. The female hormones follicle-stimulating hormone, luteinizing hormone, and 17β-estradiol, as well as the lipids total cholesterol, triglycerides, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol, were not significantly different within groups and between groups. CONCLUSIONS DBT preparations at 6.0 g/day significantly improve physical and psychological scores and significantly reduce vasomotor symptoms from baseline. The treatment was well tolerated, with no serious adverse events noted during the 12-week intervention period. The changes do not affect hormones and lipid profiles.

Abstract
This study aimed to evaluate the relationship between blood lead and serum creatinine and blood lead and serum urea nitrogen levels as biomarkers of lead exposure from subjects living in a historic polymetallic mining area in China. Elevated levels were found for blood lead, serum creatinine, and serum urea nitrogen in the mining area with mean values at 245.65 μg/l, 74.16 μmol/l, and 12.79 mmol/l, which were significantly higher than those in the control area, respectively. Moreover, the coefficients between paired results for blood lead and serum creatinine and blood lead and serum urea nitrogen were positively statistically significant (serum creatinine vs. blood lead, r = 0.35, p < 0.05; serum urea nitrogen vs. blood lead, r = 0.48, p < 0.05). With respect to the effects of sex and age on the blood lead, serum creatinine, and serum urea nitrogen levels, data analysis revealed there was a tendency for higher blood lead, serum creatinine, and serum urea nitrogen levels in females than in males, and the levels of blood lead, serum creatinine, and serum urea nitrogen increased among older residents. We conclude that females and the older population in the mining area are more susceptible to lead exposure. Blood lead, serum creatinine, and serum urea nitrogen can be useful biomarkers of lead exposure among populations under environmental stress.

Efficacy and side effects of chinese herbal medicine for menopausal symptoms: a critical review. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2013; 2012:568106. [PMID: 23365599 PMCID: PMC3551256 DOI: 10.1155/2012/568106] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/27/2012] [Accepted: 10/03/2012] [Indexed: 11/17/2022]
Abstract
This study evaluates 23 (9 Chinese and 14 non-Chinese) randomized controlled trials for efficacy and side effects of Chinese herbal medicine on menopausal symptoms. Menopause was diagnosed according to western medicine criteria in all studies while seven Chinese studies and one non-Chinese study further stratified the participants using traditional Chinese medical diagnosis "Zheng differentiation." Efficacy was reported by all 9 Chinese and 9/14 non-Chinese papers. Side effects and adverse events were generally mild and infrequent. Only ten severe adverse events were reported, two with possible association with the therapy. CHM did not increase the endometrial thickness, a common side effect of hormone therapy. None of the studies investigated long-term side effects. Critical analysis revealed that (1) high-quality studies on efficacy of Chinese herbal medicine for menopausal syndrome are rare and have the drawback of lacking traditional Chinese medicine diagnosis (Zheng-differentiation). (2) Chinese herbal medicine may be effective for at least some menopausal symptoms while side effects are likely less than hormone therapy. (3) All these findings need to be confirmed in further well-designed comprehensive studies meeting the standard of evidence-based medicine and including Zheng-differentiation of traditional Chinese medicine.

Effect of combining therapy with traditional chinese medicine-based psychotherapy and herbal medicines in women with menopausal syndrome: a randomized controlled clinical trial. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2012; 2012:354145. [PMID: 23304198 PMCID: PMC3523610 DOI: 10.1155/2012/354145] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/04/2012] [Accepted: 10/31/2012] [Indexed: 11/22/2022]
Abstract
This multicenter, randomized, controlled clinical study was designed to address the effectiveness of combined traditional-Chinese-medicine- (TCM-) based psychotherapy and Chinese herbal medicine (CHM) in the treatment of menopausal syndrome. Altogether 424 eligible women diagnosed as menopausal syndrome and categorized as Kidney-Yin/Kidney-Yang deficiency pattern in TCM were randomly assigned into 4 groups and accepted TCM-based psychotherapy (PSY), CHM, PSY + CHM, or placebo therapies, respectively, for 12 weeks, and another 12 weeks were taken as the followup. Kupperman Index (KI) and the Menopause-Specific Quality of Life (MENQOL) with its four subscales (vasomotor, physical, psychosocial, and sexual) were employed for efficacy assessment. Results showed that 400 participants completed 12-week treatment, of which 380 finished the record of KI and MENQOF at week 24. The average adjusted number of KI score decreased between baseline and 12 weeks in all groups. Statistically significant differences were detected in the average adjusted change between the PSY + CHM group and placebo at overall time points (P < 0.05). No severe adverse events occurred in each group and no significant differences were indicated between any of the three groups and placebo in adverse event proportion. We concluded that TCM psychotherapy combined with CHM has a favorable outcome in treating menopausal syndrome.
