Abstract
Chinese herbal medicines (CHM) are often used in managing cancer related symptoms but their effectiveness and safety is controversial.
We conducted this overview of meta-analyses to summarize evidence on CHM for cancer palliative care. We included systematic reviews (SRs) with meta-analyses of CHM clinical trials on patients diagnosed with any type of cancer.
Methodological quality of included meta-analyses was assessed with the Methodological Quality of Systematic Reviews (AMSTAR) Instrument. Fifty-one SRs with meta-analyses were included. They covered patients with lung (20 SRs), gastric (8 SRs), colorectal (6 SRs), liver (6 SRs), breast (2 SRs), cervical (1 SR), esophageal (1 SR), and nasopharyngeal (1 SR) cancers. Six SRs summarized evidence on various types of cancer. Methodological quality of included meta-analyses was not satisfactory.
Overall, favorable therapeutic effects in improving quality of life among cancer patients have been reported. Conflicting evidence exists for the effectiveness of CHM in prolonging survival and in reducing chemotherapy and/or radiotherapy related toxicities. No serious adverse effects were reported in all included studies. Evidence indicated that CHM could be considered as an option for improving quality of life among patients receiving palliative care. It is unclear if CHM may increase survival, or reduce therapy related toxicities.
Evidence showed that the combination of CHM and chemotherapy significantly reduced leucopenia, nausea and vomiting, thrombocytopenia and anemia in NSCLC, gastric cancer patients. It also significantly reduced nausea and vomiting in liver cancer patients. In general, CHM appears to be useful in improving leucopenia, thrombocytopenia and anemia among various types of cancer.
Base on the evidence we identified, CHM may be considered as an adjuvant option to improve QoL among cancer patients.

Ried K1, Stuart K. Complement Ther Med. 2011 Dec;19(6):319-31. doi: 10.1016/j.ctim.2011.09.003. Epub 2011 Oct 5.
Conclusions
Review suggests that management of female infertility with Chinese Herbal Medicine can improve pregnancy rates 2-fold within a 4 month period compared with Western Medical fertility drug therapy or IVF. Assessment of the quality of the menstrual cycle, integral to TCM diagnosis, appears to be fundamental to successful treatment of female infertility.
Chinese herbal medicine for female infertility: an updated meta-analysis.

Methods
We searched the Medline and Cochrane databases until December 2013 for randomized controlled trials and meta-analyses investigating Chinese herbal medicine therapy for female infertility and compared clinical pregnancy rates achieved with CHM versus WM drug treatment.
Results
Forty RCTs involving 4247 women with infertility were included in our systematic review. Meta-analysis suggested a 1.74 higher probability of achieving a pregnancy with CHM therapy than with WM therapy alone (risk ratio 1.74, 95%CI: 1.56-1.94; p<0.0001; odds ratio 3.14; 95%CI: 2.72-3.62; p<0.0001) in women with infertility. Trials included women with PCOS, endometriosis, anovulation, fallopian tube blockage, or unexplained infertility. Mean pregnancy rates in the CHM group were 60% compared with 33% in the WM group.
Conclusions
Our review suggests that management of female infertility with Chinese herbal medicine can improve pregnancy rates 2-fold within a 3-6 month period compared with Western medical fertility drug therapy. In addition, fertility indicators such as ovulation rates, cervical mucus score, biphasic basal body temperature, and appropriate thickness of the endometrial lining were positively influenced by CHM therapy, indicating an ameliorating physiological effect conducive for a viable pregnancy.

Conclusions
The standard therapeutic package for unexplained infertility in women studied here is safe for infants and the treated women, when administered by licensed professionals. While it remains challenging to have the target population complete a 6-month treatment course, during which most patients have to pay out of pocket, the extent of successfully achieved pregnancy in those who received full treatment provides meaningful outcomes, warranting further attention. A future study that includes subsidized treatment costs, encouraging the appropriate compliance rate, is warranted.

Abstract
Female infertility is when a woman of reproductive age and sexual active, without contraception, cannot get pregnant after a year and more or keeps having miscarriages. Although conventional treatments for infertility such as hormone therapy, in vitro fertilization and many more, helped many female patients with infertility get pregnant during past a few decades, it is far from satisfactory with prolonging treatment time frames and emotional and financial burden. In recent years, more patients with infertile problems are seeking to alternative and complementary medicines to achieve a better outcome. In particular, Chinese herbal medicine (CHM) is increasingly popular for treating infertility due to its effectiveness and complimentary with conventional treatments. However, the mechanisms of action of CHM in treating female infertility are not well understood. In this chapter authors reviewed research development of CHM applied in many infertile models and CHM clinical studies in many conditions associated with female infertility, published in past 15 years.
The data of review showed that CHM has either specific target mechanisms of action or multitarget mechanisms of action, via regulating relevant hormone levels in female reproductive system, improving ovary function, enhancing uterine receptivity. More studies are warranted to explore the new drugs from CHM and ensure safety, efficacy, and consistency of CHM.

Abstract
Male infertility normally refers a male’s inability to cause pregnancy in a fertile female partner after 1 year of unprotected intercourse. Male infertility in recent years has been attracting increasing interest from public due to the evidence in decline in semen quality. There are many factors contributing to the male infertility including abnormal spermatogenesis; reproductive tract anomalies or obstruction; inadequate sexual and ejaculatory functions; and impaired sperm motility, imbalance in hormone levels, and immune system dysfunction. Although conventional treatments such as medication, surgical operation, and advanced techniques have helped many male with infertility cause pregnancy in their female partners, effectiveness is not satisfactory and associated with adverse effects. Chinese herbal medicine (CHM) has been used to improve male infertility in China for a very long time and has now been increasingly popular in Western countries for treating infertility. In this chapter we summarized recent development in basic research and clinical studies of CHM in treating male infertility.
It has showed that CHM improved sperm motility and quality, increased sperm count and rebalanced inadequate hormone levels, and adjusted immune functions leading to the increased number of fertility.
Further, CHM in combination with conventional therapies improved efficacy of conventional treatments. More studies are needed to indentify the new drugs from CHM and ensure safety, efficacy, and consistency of CHM.

Background
Endometriosis is characterized by the presence of tissue that is morphologically and biologically similar to normal endometrium in locations outside the uterus. Surgical and hormonal treatment of endometriosis have unpleasant side effects and high rates of relapse. In China, treatment of endometriosis using Chinese herbal medicine (CHM) is routine and considerable research into the role of CHM in alleviating pain, promoting fertility, and preventing relapse has taken place. This review is an update of a previous review published in the Cochrane Database of Systematic Reviews 2009, issue No 3.
Objectives
To review the effectiveness and safety of CHM in alleviating endometriosis-related pain and infertility.
Search methods
We searched the Menstrual Disorders and Subfertility Group Trials Register, Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library) and the following English language electronic databases (from their inception to 31/10/2011): MEDLINE, EMBASE, AMED, CINAHL, and NLH. We also searched Chinese language electronic databases: Chinese Biomedical Literature Database (CBM), China National Knowledge Infrastructure (CNKI), Chinese Sci & Tech Journals (VIP), Traditional Chinese Medical Literature Analysis and Retrieval System (TCMLARS), and Chinese Medical Current Contents (CMCC).
Selection criteria
Randomised controlled trials (RCTs) involving CHM versus placebo, biomedical treatment, another CHM intervention; or CHM plus biomedical treatment versus biomedical treatment were selected. Only trials with confirmed randomisation procedures and laparoscopic diagnosis of endometriosis were included.
Data collection and analysis
Risk of bias assessment, and data extraction and analysis were performed independently by three review authors. Data were combined for meta-analysis using relative risk (RR) for dichotomous data. A fixed-effect statistical model was used, where appropriate. Data not suitable for meta-analysis were presented as descriptive data.
Main results
Two Chinese RCTs involving 158 women were included in this review. Although both these trials described adequate methodology they were of limited quality. Neither trial compared CHM with placebo treatment. There was no evidence of a significant difference in rates of symptomatic relief between CHM and gestrinone administered subsequent to laparoscopic surgery (RR 1.04, 95% CI 0.91 to 1.18). There was no significant difference between the CHM and gestrinone groups with regard to the total pregnancy rate (69.6% versus 59.1%; RR 1.18, 95% CI 0.87 to 1.59, one RCT). CHM administered orally and then in conjunction with a herbal enema resulted in a greater proportion of women obtaining symptomatic relief than with danazol (RR 5.06, 95% CI 1.28 to 20.05; RR 5.63, 95% CI 1.47 to 21.54, respectively). Oral plus enema administration of CHM resulted in a greater reduction in average dysmenorrhoea pain scores than did danazol (mean difference (MD) -2.90, 95% CI -4.55 to -1.25). For lumbosacral pain, rectal discomfort, or vaginal nodules tenderness, there was no significant difference between CHM and danazol. Overall, 100% of women in both studies showed some improvement in their symptoms. Women taking CHM had fewer side effects than those taking either gestrinone or danazol.
Authors’ conclusions
Post-surgical administration of CHM may have comparable benefits to gestrinone. Oral CHM may have a better overall treatment effect than danazol and it may be more effective in relieving dysmenorrhoea when used in conjunction with a CHM enema. CHM appears to have fewer side effects than either gestrinone or danazol. However, more rigorous research is required to accurately assess the potential role of CHM in treating endometriosis.
Plan Language Summary
Chinese herbs for endometriosis
Endometriosis is a common gynaecological condition causing menstrual and pelvic pain. Treatment involves surgery and hormonal drugs, with potentially unpleasant side effects and high rates of reoccurrence of endometriosis. The two small studies in this review suggest that Chinese herbal medicine (CHM) may be as effective as gestrinone and may be more effective than danazol in relieving endometriosis-related pain, with fewer side effects than experienced with conventional treatment. However, the two trials included in this review were small and of limited quality so these findings must be interpreted cautiously. Better quality randomised controlled trials are needed to investigate a possible role for CHM in the treatment of endometriosis
