The American journal of Chinese medicine. 2021;(7):1557-1575
Abstract
Breast cancer is currently the most common cancer in women, and it accounts for 11.6% of all cancer diagnoses in 2018. Breast cancer patients frequently resort to alternative medicine in addition to conventional Western therapy. This study is to evaluate clinical effectiveness of Chinese herbal medicine (CHM) on breast cancer by conducting meta-analyses on 81 randomized controlled trials (RCTs) with a total of 7215 subjects from eight databases. All RCTs compared patients using Western therapy alone and those using additional CHM therapy to evaluate the difference of primary (tumor response, mean time to progression (mTTP), overall survival (OS) and progression free survival (PFS)) and secondary outcome measures (tumor markers). Results showed that under the RECIST1.1 criteria, 52% patients with additional CHM therapy (67%, under WHO criteria) achieved either a complete response (CR) or a partial response (PR), compared to 38% patients with Western therapy alone (53%, under the WHO criteria). The risk ratio was 1.31 ([Formula: see text] < 0.00001, 95% CI = 1.15-1.50) for patients with CHM plus Western therapy and 1.25 ([Formula: see text] < 0.00001, 95% CI = 1.18-1.98) for those with Western therapy. Moreover, patients with complementary CHM therapy were associated with an mTTP of 2.79 months longer ([Formula: see text] < 0.00001) and an OS of 1.90 months longer ([Formula: see text] < 0.00001); they also had an increase in 3-year PFS ([Formula: see text]= 0.002), 2- ([Formula: see text]= 0.0002) and 5-year ([Formula: see text]= 0.006) OS rates. Therefore, complementary CHM therapy might demonstrate clinical benefits for breast cancer patients in terms of tumor response and survival. Clinical studies with further stratification of tumor stages and intervention types are highly warranted.

Oxidative medicine and cellular longevity. 2018;:8394818
Abstract
Liver disease, involving a wide range of liver pathologies from fatty liver, hepatitis, and fibrosis to cirrhosis and hepatocellular carcinoma, is a serious health problem worldwide. In recent years, many natural foods and herbs with abundant phytochemicals have been proposed as health supplementation for patients with hepatic disorders. As an important category of phytochemicals, natural polyphenols have attracted increasing attention as potential agents for the prevention and treatment of liver diseases. The striking capacities in remitting oxidative stress, lipid metabolism, insulin resistance, and inflammation put polyphenols in the spotlight for the therapies of liver diseases. It has been reported that many polyphenols from a wide range of foods and herbs exert therapeutic effects on liver injuries via complicated mechanisms. Therefore, it is necessary to have a systematical review to sort out current researches to help better understand the potentials of polyphenols in liver diseases. In this review, we aim to summarize and update the existing evidence of natural polyphenols in the treatment of various liver diseases by in vitro, in vivo, and clinical studies, while special attention is paid to the action mechanisms.

Zheng, J, Zhou, Y, Li, Y, Xu, DP, Li, S, Li, HB
Nutrients. 2016;(8)
Abstract
Spices have been widely used as food flavorings and folk medicines for thousands of years. Numerous studies have documented the antioxidant, anti-inflammatory and immunomodulatory effects of spices, which might be related to prevention and treatment of several cancers, including lung, liver, breast, stomach, colorectum, cervix, and prostate cancers. Several spices are potential sources for prevention and treatment of cancers, such as Curcuma longa (tumeric), Nigella sativa (black cumin), Zingiber officinale (ginger), Allium sativum (garlic), Crocus sativus (saffron), Piper nigrum (black pepper) and Capsicum annum (chili pepper), which contained several important bioactive compounds, such as curcumin, thymoquinone, piperine and capsaicin. The main mechanisms of action include inducing apoptosis, inhibiting proliferation, migration and invasion of tumors, and sensitizing tumors to radiotherapy and chemotherapy. This review summarized recent studies on some spices for prevention and treatment of cancers, and special attention was paid to bioactive components and mechanisms of action.

Huang, Y, Wu, T, Zeng, L, Li, S
The Cochrane database of systematic reviews. 2012;(3):CD004877
Abstract
BACKGROUND Chinese herbal medicines are commonly used to treat sore throat in China and are used worldwide by practitioners of traditional Chinese medicine (TCM). Their efficacy in treating sore throat has not previously been systematically reviewed. OBJECTIVES To assess the efficacy and safety of Chinese herbal medicines for patients with sore throat. SEARCH METHODS We searched CENTRAL (The Cochrane Library Issue 4, 2011) which contains the Cochrane Acute Respiratory Infections Group's Specialised Register; MEDLINE (1966 to week 3, November 2011); EMBASE (1980 to December 2011); AMED (1985 to December 2011); the Chinese Biomedical Database (CBM) (1975 to December 2011); and China National Knowledge Infrastructure (CNKI) (1994 to December 2011). SELECTION CRITERIA We included randomised controlled trial (RCTs) assessing Chinese herbal medicines for the treatment of sore throat, with the outcomes of recovery, inefficacy, and adverse events. DATA COLLECTION AND ANALYSIS The three review authors extracted and analysed the data. One review author contacted the study authors of potential RCTs. MAIN RESULTS We included 12 studies involving 1954 participants. We identified ten studies as being of methodologically poor quality and two studies as being of medium quality. We did not perform a meta-analysis but reported the results separately. Six formulations were shown to be superior to the control in improving recovery: Ertong Qingyan Jiere Koufuye was more effective than Fufang Shuanghua Koufuye for acute pharyngitis (odds ratio (OR) 2.52; 95% confidence interval (Cl) 1.11 to 5.74); Yanhouling mixture was more effective than gentamicin atomised inhalation for acute pharyngitis (OR 5.39; 95% CI 2.69 to 10.81); Qinganlan Liyan Hanpian was more effective than Fufang Caoshanhu Hanpian for acute pharyngitis (OR 2.25; 95% CI 1.08 to 4.67); sore throat capsules were more effective than antibiotics (intravenous cefalexin) for acute pharyngitis or acute tonsillitis (OR 2.36; 95% CI 1.01 to 5.51); compound dandelion soup was more effective than sodium penicillin for acute purulent tonsillitis (OR 5.06; 95% CI 1.70 to 15.05); and eliminating heat by nourishing yin and relieving sore-throat methods combined with Dikuiluqan Hanpian was more effective than Dikuiluqan Hanpian alone for children with chronic pharyngitis (OR 2.63; 95% CI 1.02 to 6.79). Another six formulations were shown to be equally efficacious as the control. AUTHORS' CONCLUSIONS Based on the existing evidence in this review, some Chinese herbal medicines for treating sore throat appeared efficacious. However, due to the lack of high quality clinical trials, the efficacy of Chinese herbal medicine for treating sore throat is controversial and questionable. Therefore we cannot recommend any kind of Chinese medical herbal formulation as an effective remedy for sore throat.

Abstract
BACKGROUND Heart failure is a major public health problem world-wide. Shengmai (a traditional Chinese herbal medicine) has long been used as a complementary treatment for heart failure in China. OBJECTIVES To determine the effect (both benefits and harms) of shengmai plus usual treatment versus usual treatment alone for heart failure. SEARCH STRATEGY We searched the following electronic databases: the Cochrane Central Register of Controlled Trials (CENTRAL) on The Cochrane Library (Issue 2, 2005), MEDLINE (1966 to May 2005), EMBASE (1984 to March 2004), AMED (1985 to July 2005), Chinese BioMedical Literature Database(1978 to April 2004), DARE (Issue 2, 2005) and BIOSIS (1997 to 2004). Seventeen Chinese journals were also handsearched. SELECTION CRITERIA Trials of shengmai plus usual treatment versus usual treatment alone for heart failure were included. Randomized or quasi-randomized controlled trials, regardless of whether they were blinded, were included. DATA COLLECTION AND ANALYSIS Two reviewers selected trials, assessed methodological quality and extracted data independently. Dichotomous and continuous data were calculated as relative risk (RR), and weighted mean differences (WMD), respectively. No heterogeneity was detected between included trials. A fixed-effect model was used to perform meta-analysis. MAIN RESULTS Nineteen trials were included studies. Methodological quality of the included studies was low. Compared to usual treatment alone, shengmai plus usual treatment showed significant improvement in New York Heart Association classification of clinical status (RR 0.32; 95% CI 0.25 to 0.40), mortality (RR 0.25; 95% CI 0.07 to 0.86), and tumour necrosis factor-alpha (WMD -0.52; 95% CI -0.99 to -0.05). Improvements were also seen in hemodynanic tests (one trial, 100 participants). No adverse affects were reported in any of the included trials. AUTHORS' CONCLUSIONS It is possible that shengmai plus usual treatment may be beneficial compared to usual treatment alone for heart failure. However the evidence is weak because of the poor quality of the included trials. Long-term and high quality studies are needed to provide clear evidence for the future use of shengmai.
