IMPORTANCE: Per preliminary studies, Shengdi Dahuang Decoction (SDD) is potentially effective for acute intracerebral haemorrhage (ICH); however, its effectiveness has not been rigorously assessed in extensive randomised clinical trials. OBJECTIVE: To evaluate whether SDD can improve 90-day functional outcomes in patients with ICH. DESIGN: Randomised, double-blind, placebo-controlled clinical trial included patients with acute ICH within 4 hours of symptom onset at five hospitals in Shanghai, China. INTERVENTIONS: Patients were randomised 1:1 to receive either SDD granules (each sachet contained 15 g of raw Rehmannia glutinosa and 5 g of raw rhubarb) or placebo granules orally or via a nasogastric tube (as soon as possible within 12 hours of onset, two times daily for 7 days), in addition to ICH guideline-directed treatments. Per our preclinical study, SDD reduces inflammatory injury after ICH in rats. MAIN OUTCOMES: The primary outcome measure was the proportion of patients with a score ranging 0-1 on the modified Rankin Scale (mRS) on the 90th day. RESULTS: Of the total 1211 participants with cerebral haemorrhage assessed for eligibility, 483 were enrolled. Of this, 242 participants were randomly assigned to receive SDD granules and 241 to receive placebo granules (mean age, 62.7 years; 72.9% male). Among these, 112 (46.3%) and 84 (34.9%) patients in the SDD and placebo groups, respectively, had an mRS score of 0-1 on the 90th day (adjusted relative risk 1.20, 95% CI 1.00 to 1.43; p=0.046) . The proportion of patients with poor clinical outcomes (mRS score of 5 or 6 at 90 days) was higher in the placebo group (11.2%) than in the SDD group (5.4%) (p=0.021). The 90-day mortality rate (p=0.299), 7-day National Institute of Health Stroke Scale score (p=0.583), 7-day Glasgow Coma Scale score (p=0.577), 24-hour haematoma enlargement rate (p=0.675) or 7-day relative perihaematomal oedema did not significantly differ (p=0.343) between the groups. The incidence of adverse events between the two groups did not differ significantly (p>0.05). CONCLUSIONS: In patients with acute ICH, incorporating SDD as a supplementary intervention alongside guideline-directed treatments

ETHNOPHARMACOLOGICAL RELEVANCE: In traditional Chinese Medicine, Rehmannia glutinosa (Gaertn.) DC., as the principle herb of ShengDiHuang Decotion (SDHD), has the effect of cooling blood and hemostasis, and tonifying the yin and kidney. Rheum L., as adjuvant herbs, assist Rehmannia glutinosa (Gaertn.) DC. to promote blood circulation to remove blood stasis. AIM OF STUDY: To study the mechanism of Rhein (RH) involved in the promotion of Rehmannioside D (RD) absorption by pharmacokinetic studies, single-pass intestinal perfusion, Caco-2 cell models, molecular docking technique and western blotting. MATERIALS AND METHODS: Initially, the intestinal absorption of RD in the presence or absence of RH was conducted through pharmacokinetic studies. Thereafter, the intestinal absorption of RD and RH was studied using the single-pass intestinal perfusion and Caco-2 cell models. Finally, using molecular docking technique and western blotting. RESULTS: We found that the promotion of RD absorption by RH was mediated by breast cancer resistance and multidrug resistance-associated protein 2, thereby affecting the permeability of the intestinal epithelium. Additionally, RH and RD can competitively bind to breast cancer resistance and multidrug resistance-associated protein 2, and that RH inhibits the expression of breast cancer resistance and multidrug resistance-associated protein 2 in the ileum to promote the intestinal absorption of RD. CONCLUSION: This study reveals the mechanisms associated with the RH-mediated promotion of RD absorption and provides a basis for further exploring the synergistic effect of Rehmannia glutinosa (Gaertn.) DC and rhubarb.

ETHNOPHARMACOLOGICAL RELEVANCE: Samul-tang (Si-Wu-tang in Chinese, Shimotsu-to in Japanese), widely used in eastern Asia, is composed of Angelica gigas (Angelicae Gigantis Radix), Cnidium officinale (Cnidii Rhizoma), Paeonia lactiflora (Paeonia Radix) and Rehmannia glutinosa (Rehmanniae Radix Preparata). Paeoniflorin, one of active components in Samul-tang has anti-platelet, anti-inflammation, anti-cancer and neuroprotective properties. However, there is no information about the effects of gender and food intake on the pharmacokinetics of paeoniflorin till now. AIM OF THE STUDY: This study was conducted to investigate whether food and gender could influence pharmacokinetic profiles of paeoniflorin after oral administration of Samul-tang. MATERIALS AND METHODS: Male and female rats were administered with a single oral dose of Samul-tang equivalent to 80 mg/kg of paeoniflorin. Plasma concentrations of paeoniflorin were measured by high-performance liquid chromatography. The statistical differences of each group were evaluated using the analysis of variance (ANOVA) or Student t-test. RESULTS: The pharmacokinetic parameters of paeoniflorin were not significant different by gender difference. However, the maximum plasma concentration (C(max), 0.47±0.29 μg/mL versus 1.10±0.35 μg/mL), area under the concentration-time curve (AUC(0→∞), 1.41±0.89 h · μg/mL versus 3.12±1.61 h · μg/mL) and relative bioavailability (F(rel)=2.21) of fed rats were significantly increased in comparison with those of fasted rats (P<0.05). CONCLUSION: Taken together, food intake can affect both the rate and extent of absorption of paeoniflorin when Samul-tang was administered orally. Furthermore, this study demonstrates a readily preparative HPLC method in the research of traditional herbal medicine.

We investigated whether an aqueous extract of Rehmannia glutinosa steamed root (RGAE) inhibits secretion of tumour necrosis factor-alpha (TNF-alpha) and interleukin-1 (IL-1) from primary cultures of mouse astrocytes. RGAE dose-dependently inhibited the TNF-alpha secretion by astrocytes stimulated with substance P (SP) and lipopolysaccharide (LPS). IL-1 has been shown to elevate TNF-alpha secretion from LPS-stimulated astrocytes while having no effect on astrocytes in the absence of LPS. We therefore investigated whether IL-1 mediated inhibition of TNF-alpha secretion from astrocytes by RGAE. Treatment of RGAE to astrocytes stimulated with both LPS+SP decreased IL-1 secretion. Moreover, incubation of astrocytes with IL-1 antibody abolished the synergistic cooperative effect of LPS+SP. These results suggest that RGAE may inhibits TNF-alpha secretion by inhibiting IL-1 secretion and that RGAE has an anti-inflammatory activity in the central nervous system curing some pathological disease states.

Shi-Quan-Da-Bu-Tang (Ten Significant Tonic Decoction), or SQT (Juzentaihoto, TJ-48) was formulated by Taiping Hui-Min Ju (Public Welfare Pharmacy Bureau) in Chinese Song Dynasty in AD 1200. It is prepared by extracting a mixture of ten medical herbs (Rehmannia glutinosa, Paeonia lactiflora, Liqusticum wallichii, Angelica sinesis, Glycyrrhiza uralensis, Poria cocos, Atractylodes macrocephala, Panax ginseng. Astragalus membranaceus and Cinnamomum cassia) that tone the blood and vital energy, and strengthen health and immunity. This potent and popular prescription has traditionally been used against anemia, anorexia, extreme exhaustion, fatigue, kidney and spleen insufficiency and general weakness, particularly after illness. In order to restore immunity in cancer patients, potentiate the therapeutic effect and ameliorate adverse toxicity of anticancer agents, 116 Chinese herbal formularies (Kampo) have been screened and evaluated. Fifteen compounds were found to have such actions. Among these, SQT was selected as the most effective as a potent biological response modifier. During the last eight years, animal models and clinical studies have revealed that SQT demonstrates extremely low toxicity (LD50 > 15 g/kg op murine), self-regulatory and synergistic actions of its components in immunomodulatory and immunopotentiating effects (by stimulating hemopoietic factors and interleukins production in association with NK cells, etc.), potentiates therapeutic activity in chemotherapy (mitomycin, cisplatin, cyclophosphamide and fluorouracil) and radiotherapy, inhibits the recurrence of malignancies, prolongs survival, as well as ameliorate and/or prevents adverse toxicities (GI disturbances such as anorexia, nausea, vomiting, hematotoxicity, immunosuppression, leukopenia, thrombocytopenia, anemia and nephropathy, etc.) of many anticancer drugs. The application and mechanistic studies of SQT in future development have potential importance in basic and clinical research of the traditional Chinese therapeutic approach of "toning the blood and strengthening Qi (vital energy)" in cancer immunotherapy.

Psoriasis is a chronic inflammatory disease that places a great burden on both individuals and society. The use of East Asian herbal medicine (EAHM) in combination with conventional medications is emerging as an effective strategy to control the complex immune-mediated inflammation of this disease from an integrative medicine (IM) perspective. The safety and efficacy of IM compared to conventional medicine (CM) were evaluated by collecting randomized controlled trial literature from ten multinational research databases. We then searched for important key materials based on integrated drug data mining. Network pharmacology analysis was performed to predict the mechanism of the anti-inflammatory effect. Data from 126 randomized clinical trials involving 11,139 patients were used. Compared with CM, IM using EAHM showed significant improvement in the Psoriasis Area Severity Index (PASI) 60 (RR: 1.4280; 95% CI: 1.3783-1.4794; p < 0.0001), PASI score (MD: -3.3544; 95% CI: -3.7608 to -2.9481; p < 0.0001), inflammatory skin lesion outcome, quality of life, serum inflammatory indicators, and safety index of psoriasis. Through integrated data mining of intervention data, we identified four herbs that were considered to be representative of the overall clinical effects of IM: Rehmannia glutinosa (Gaertn.) DC., Isatis tinctoria subsp. athoa (Boiss.) Papan., Paeonia × suffruticosa Andrews, and Scrophularia ningpoensis Hemsl. They were found to have mechanisms to inhibit pathological keratinocyte proliferation and immune-mediated inflammation, which are major pathologies of psoriasis, through multiple pharmacological actions on 19 gene targets and 8 pathways in network pharmacology analysis. However, the quality of the clinical trial design and pharmaceutical quality control data included in this study is still not optimal; therefore, more high-quality clinical and non-clinical studies are needed to firmly validate the information explored in this study. This study is informative in that it presents a focused hypothesis and methodology for the value and direction of such follow-up studies.

BACKGROUND/PURPOSE: The purpose of this study was to use heart rate variability (HRV) to investigate the effects of distilled Cervi Pantotrichum Cornu pharmacopuncture and Rehmannia glutinosa pharmacopuncture on the autonomic nervous system. MATERIALS AND METHODS: Forty healthy male participants were divided into two groups: the participants of the C-group received distilled Cervi Pantotrichum Cornu pharmacopuncture and those of the R-group received Rehmannia glutinosa pharmacopuncture. The study design was a randomized, double-blind clinical trial. Each participant received one of the two solutions injected at GB21 (Jianjing). The changes in HRV were measured seven times using the QECG-3: LXC3203 system (LAXTHA Inc. Korea). Time-dependent changes in HRV for each group were analyzed using the paired t test (significance level: p < 0.05), and the difference in the HRV fluctuations between the two experimental groups was evaluated using the independent sample test (significance level: p < 0.05). RESULTS AND CONCLUSION: The results showed that Cervi Pantotrichum Cornu pharmacopuncture and Rehmannia glutinosa pharmacopuncture tended to activate the autonomic nervous system within the normal range. Cervi Pantotrichum Cornu pharmacopuncture tended to activate the sympathetic nervous system, whereas Rehmannia glutinosa pharmacopuncture tended to activate both the sympathetic and parasympathetic nervous systems.

The clinical study reported here was conducted in order to analyze the anti-obesity effect of the steamed root of Rehmannia glutinosa Libosch (Shu Dihuang), a Chinese herbal medicine widely used for the treatment of metabolic diseases. To understand the mechanism(s) underlying the beneficial effects of R. glutinosa, we investigated the changes in gut microbiota after herbal intervention through 16S rRNA gene-based pyrosequencing analyses. Twelve female middle-aged subjects (40-65 years old) with body mass index (BMI) over 25 kg m(-2) were included in this study which involved intake of steamed roots of R. glutinosa for eight weeks. The subjects were visited for anthropometric measurements every two weeks and fecal samples were collected before and after the intervention. All subjects showed a significantly decreased waist circumference following the herbal treatment. The relative abundances of fecal microbiota suggested an association of intake of R. glutinosa with increases in phylum Actinobacteria and genus Bifidobacterium, while phylum Firmicutes and genus Blautia were decreased in response to the herbal treatment. Based on these findings, it is conceivable that a decrease in the waist circumferences after R. glutinosa intake may be related to alteration of intestinal microbiota and the herbal intervention has the potential as a prebiotic.

Anti-inflammatory factor (AIF) is a water soluble extract of three herbs, Panax notoginseng (Burk.) F. H. Chen, Rehmannia glutinosa Libosch and Eleutherococcus senticosus. The present study aimed to investigate the safety and efficacy of herb extracts, AIF, on Korean knee osteoarthritis patients for six weeks. Fifty seven patients with knee osteoarthritis, ranging from 43 to 73 years of age, who fulfilled the "American College of Rheumatology" (ACR) classification of idiopathic osteoarthritis of knee and radiographic criteria were randomly selected and enrolled for the study. After initial screening and resting period, two capsules each of AIF (Each capsule contains; 400 mg) and similar identical placebo were administered twice a day to both groups. Pain intensity at second, fourth, and sixth weeks of study as well as one week after discontinuation of drugs was assessed by using 100 mm visual analogue scale (VAS). Changes in the Korean version of the Western Ontario and McMaster Universities (K-WOMAC) index score were compared at the initiation and completion of the study. VAS assessed by patients were significantly reduced (at visit 2; 54.64+/-14.72, at visit 4, 37.32+/-16.58, p< 0.001) after AIF administration. Results showed an improvement in the physical function of K-WOMAC scale which was significantly higher (p=0.013) in AIF than placebo group, and decreases of total K-WOMAC score were also significantly higher (p=0.030) in AIF groups than placebo group. No serious adverse effect was observed, and there was no difference in incidence of adverse effect between AIF and placebo groups. In this population of Korean patients with knee osteoarthritis, AIF was found to be safe, tolerable and effective for symptomatic improvement of pain and physical function.

ETHNOPHARMACOLOGICAL RELEVANCE: As a common cause of thyrotoxicosis, Graves' disease (GD) has shown potential therapeutic advantages when treated with Traditional Chinese Medicine (TCM). Immune dysfunction serves as a pathological basis of GD, and TCM formulations may regulate abnormal immune status; however, robust evidence-based support and clearly defined pharmacological mechanisms are still lacking. AIM OF THE STUDY: Therefore, this study aims to employ meta-analysis and network pharmacology methods to confirm the therapeutic effects of TCM compound prescriptions on thyroid function and related immune functions, and to explore the potential mechanisms of TCM in treating GD. MATERIALS AND METHODS: A systematic review and meta-analysis were performed focusing on RCTs that examined the efficacy of Chinese herbal compound prescriptions for the treatment of Graves' disease. The studies were collected from eight major electronic databases: the Cochrane Library, PubMed, Web of Science, Embase, Chinese National Knowledge Infrastructure (CNKI), Sinomed, Wanfang Database, and the VIP Information-Chinese Scientific Journal Database. The search included publications available up to August 2025. Outcomes assessed included TCM syndrome scores, thyroid function-related indicators, immune-related indicators, and adverse reactions associated with Chinese herbal treatments. After conducting the systematic review and meta-analysis, we utilized cluster analysis and network pharmacology methods to pinpoint the essential herbs within Chinese herbal formulas. The potential bioactive constituents, related targets, and pathways of these core herbs were subsequently analyzed. RESULTS: In total, 44 RCTs were included to compare with the group receiving conventional Western medical treatment. The TCM group demonstrated a reduction in TCM syndrome scores (SMD = -1.48, 95% CI: -1.89 to -1.08, P = 0.000), an increased response rate (RR: 1.18, 95% CI: 1.11 to 1.24, P = 0.000; I2 = 60.6%), and varying degrees of improvement in both thyroid function-related indices and immune system-related indices. The incidence of adverse reactions under TCM compound treatment was lower than that in the We

OBJECTIVES: To carry out a quantitative assessment of the therapeutic effect of Chinese herbal medicine (CHM), with Rehmannia glutinosa as the main ingredient, in treating perimenopausal syndrome (PMS) in breast cancer patients. METHODS: Randomized controlled trials (RCTs) comparing CHM with Rehmannia glutinosa as the principal ingredient and Western medicine in treating PMS among breast cancer patients were retrieved from multiple databases. These databases included PubMed, Cochrane library, Embase, China National Knowledge Infrastructure, Wanfang Data, China Science and Technology Journal Database, and China Biology Medicine Database. The primary outcome was the change in the Kupperman index by the end of the follow-up period. Secondary outcomes were changes in Karnofsky performance status (KPS), the functional assessment of cancer therapy - breast (FACT-B), the percentages of T-cells, levels of gonadal hormones, and tumor markers in peripheral blood at the end of follow-up, and adverse events. RESULTS: The meta-analysis included 17 RCTs involving 1,139 patients showing that CHM with Rehmannia glutinosa as the monarch drug significantly improved the Kupperman index (MD= -12.79, p<0.01), KPS score and increased the percentage of CD4 cells, reduced the percentage of CD8 cells, and improved the CD4/CD8 ratio in peripheral blood, compared to Western medicine. There were no significant differences in FACT-B scores. Levels of gonadal hormones in peripheral blood did not exhibit significant variations, and no severe adverse reactions were detected. CONCLUSION: These data suggest that CHM with Rehmannia glutinosa as the monarch drug may be applied in the treatment of PMS in patients with breast cancer. These results should be considered in the context of the methodological flaws and high heterogeneity of the included RCTs.PROSPERO No. ID: CRD42022384810. Copyright: © Saudi Medical Journal.

ETHNOPHARMACOLOGICAL RELEVANCE: Stroke is one of the leading causes of death and disability. The only FDA-approved therapy for treating stroke is tissue plasminogen activator (tPA), exhibiting a short therapeutic window. Due to this reason, only a small number of patients can be benefitted in this critical period. In addition, the use of endovascular interventions may reverse vessel occlusion more effectively and thus help further improve outcomes in experimental stroke. During recovery of blood flow after ischemia, patients experience cognitive, behavioral, affective, emotional, and electrophysiological changes. Therefore, it became the need for an hour to discover a novel strategy for managing stroke. The drug discovery process has focused on developing herbal medicines with neuroprotective effects via modulating neuroplasticity. AIM OF THE STUDY: We gather and highlight the most essential traditional understanding of therapeutic plants and their efficacy in cerebral ischemia-reperfusion injury. In addition, we provide a concise summary and explanation of herbal drugs and their role in improving neuroplasticity. We review the pharmacological activity of polyherbal formulations produced from some of the most frequently referenced botanicals for the treatment of cerebral ischemia damage. MATERIALS AND METHODS: A systematic literature review of bentham, scopus, pubmed, medline, and embase (elsevier) databases was carried out with the help of the keywords like neuroplasticity, herbal drugs, neural progenitor cells, neuroprotection, stem cells. The review was conducted using the above keywords to understand the therapeutic and mechanistic role of herbal neuroprotective agents on neuroplasticity in cerebral ischemic-reperfusion injury. RESULTS: Neuroplasticity emerged as an alternative to improve recovery and management after cerebral ischemic reperfusion injury. Neuroplasticity is a physiological process throughout one's life in response to any stimuli and environment. Traditional herbal medicines have been established as an adjuvant to stroke therapy since they were used from ancient times and provided promising effects as an adjuvant to experimental stroke.

ETHNOPHARMACOLOGY RELEVANCE: Diabetic retinopathy (DR) is a general complication of diabetes, which has become a serious threat to human health worldwide. However, the best treatment is still under development. Qiming (QM) granules are mainly composed of Astragalus membranaceus, Pueraria lobata, Rehmannia Glutinosa, Lycium barbarum, Cassiae Semen, Fructus Leonuri, Pollen Typhae, and Leech, which are beneficial to qi, nourish liver and kidney, and clear collaterals and eyes. The treatment of DR is a comprehensive application based on the above traditional Chinese medicine. In recent years, satisfactory results have been achieved for DR. AIM OF THE STUDY: Through the traditional application analysis, network pharmacology analysis and clinical research summary of QM granules, to review the effectiveness and advantages of QM granules in the treatment of DR comprehensively. MATERIALS AND METHODS: Analysis of main active components of QM granules by network pharmacology and prediction of mechanism of action of QM granules on DR. Further, PubMed, Web of Science, and China National Knowledge Infrastructure were used to search literature, using the keywords of "Qiming granules", "diabetic retinopathy", "clinical research" and their combinations, mainly from 1999 to 2022. RESULTS: Traditional pharmacological analysis, Network pharmacological analysis, animal experiments, and clinical studies have confirmed that QM granules plays a role in the treatment of DR through multiple components, multiple targets, and multiple channels. CONCLUSIONS: This systematic review for the first time provides meaningful information for the further study of the pharmacodynamic material basis and pharmacological mechanism of QM granules, and also provides a basis for further study of quality markers and quality control of QM granules.

ETHNOPHARMACOLOGICAL RELEVANCE: Amenorrhea caused by antipsychotic drugs is not uncommon in clinical practice, and various treatment strategies are used to treat the condition. Chinese herbal medicine has its own theory for amenorrhea caused by antipsychotic drugs and has developed its own medication methods. AIM OF THE STUDY: To review and conduct meta-analysis of the use of traditional Chinese herbal medicine in treatment of amenorrhea caused by antipsychotic drugs. MATERIALS AND METHODS: A search was conducted across seven Chinese electronic databases (the China National Knowledge Infrastructure (CNKI) database, the China Science and Technology Journal Database, the Wanfang Database, the SinoMed, the Foreign Medical Literature Retrieval Service(FMRS), the Chinese University of Hong Kong Library, the Airiti Library), and the following English databases: MEDLINE, PreMEDLINE, OLD MEDLINE、Publisher Supplied Citation in pubmed; JBI EBP Database, EBM Reviews, Embase, OVID Emcare, Ovid MEDLINE(R), Maternity & Infant Care Database(MIDIRS), APA PsycInfo in OVID, and Cochrane Database of Systematic Reviews (Cochrane Reviews), Database of Abstracts of Reviews of Effects (Other Reviews), Cochrane Central Register of Controlled Trials (Clinical Trials),The Cochrane Methodology Register (Method Studies), Health Technology Assessment Database (Technology Assessments), NHS Economic Evaluation Database (Economic Evaluations) in Cochrane Library; and four databases (Science Direct, ProQuest, Web of Science, and Scopus) in official website using common standards and inclusion/exclusion criteria. The remaining reports were used for preliminary studies. Due to inconsistencies in control groups, randomized controlled trials and articles that combined with other drugs were also excluded. This study is a META analysis of a single rate. RESULTS: Initial screening returned 912 potentially relevant publications in all databases. After subsequent filtering, a total of 18 articles were included in the analysis. The overall effectiveness for treatment amenorrhea caused by antipsychotic drugs using traditional Chinese herbal medicine was 0.91, with 95% confidence interval of 0.89-0.93. Not

Chinese herbal medicine has been increasingly used for patients with postmenopausal hypertension in China. A comprehensive literature search was performed in 7 electronic databases from their inception up to December 17, 2017 to examine the efficacy and safety of Chinese herbal medicine for postmenopausal hypertension. Thirty-nine randomized controlled trials involving 3, 823 participants were included. Meta-analyses favored Chinese herbal medicine plus antihypertensive drugs on blood pressure, blood pressure variability, postmenopausal symptoms, quality of life, and hormone levels compared with antihypertensive drugs. No severe adverse effects were identified. Er-xian decoction was the most frequently prescribed herbal formula, while Rehmannia glutinosa Libosch. was the most commonly used single herb. Chinese herbal medicine as complementary therapy maybe beneficial for postmenopausal hypertension. However, the effectiveness and safety of the decoction are still uncertain due to methodological shortcomings. Well-conducted trials are warranted to resolve the issue.

Clinically, oral Chinese herbal medicine (CHM) is widely used in the treatment of psoriasis. This review evaluates the effects of oral CHM in combination with pharmacotherapy for psoriasis vulgaris. The Cochrane Library, PubMed, Embase, CINAHL, CNKI, and CQVIP were searched from their inceptions to November 2012. Randomized controlled trials (RCTs) investigating CHM plus pharmacotherapy compared to pharmacotherapy were included. Data were analyzed using Review Manager 5.1.0. Seventeen RCTs were included, conducted in China, and employed a diversity of both herbal medicines and pharmacotherapies. When the meta-analyses were restricted to studies that used a well-known pharmacotherapy as the comparator with 60% or greater clinical improvement in psoriasis as the outcome, five studies used oral acitretin, one used topical calcipotriol, and one used topical clobetasol propionate as control interventions. At the end of treatment, there was a benefit for the pooled result of the five studies that compared CHM plus acitretin with acitretin alone and no serious adverse events were reported. However, none of these studies was blind, so there is considerable risk of bias in this result. In addition, there was inadequate reporting of longer-term results, so it remains unclear whether the reported effect could be maintained or whether the prolonged use of the CHM in conjunction with acitretin would be safe. The main plants used in these studies, Rehmannia glutinosa root, Salvia miltiorrhiza root, and Lithospermum erythrorhizon root, have shown anti-inflammatory and/or antiproliferative effects in experimental studies. These actions may at least partially explain the observed results. © 2014 The International Society of Dermatology.
