“…Both studies demonstrate significantly improved ovulation rates for animals treated with two doses of Tribulus terrestris extracts compared to controls. Although the endocrinological effects were not described in either study, laboratory findings of ovulation induction are supported by the clinical findings of elevated FSH following treatment with Tribulus terrestris [ 56 ] (Table 2 ).…”

“…However, the evidence for Tribulus terrestris should be interpreted with caution due to risks for bias in clinical studies. One study was uncontrolled with a small number of healthy participants [ 56 ], the second study did not report baseline characteristics, methods for allocation to treatment groups and data were not statistically analysed [ 60 ] (Table 1 ).…”

BackgroundPolycystic ovary syndrome (PCOS) is a prevalent, complex endocrine disorder characterised by polycystic ovaries, chronic anovulation and hyperandrogenism leading to symptoms of irregular menstrual cycles, hirsutism, acne and infertility. Evidence based medical management emphasises a multidisciplinary approach for PCOS, as conventional pharmaceutical treatment addresses single symptoms, may be contra-indicated, is often associated with side effects and not effective in some cases. In addition women with PCOS have expressed a strong desire for alternative treatments. This review examines the reproductive endocrine effects in PCOS for an alternative treatment, herbal medicine. The aim of this review was to identify consistent evidence from both pre-clinical and clinical research, to add to the evidence base for herbal medicine in PCOS (and associated oligo/amenorrhoea and hyperandrogenism) and to inform herbal selection in the provision clinical care for these common conditions.MethodsWe undertook two searches of the scientific literature. The first search sought pre-clinical studies which explained the reproductive endocrine effects of whole herbal extracts in oligo/amenorrhoea, hyperandrogenism and PCOS. Herbal medicines from the first search informed key words for the second search. The second search sought clinical studies, which corroborated laboratory findings. Subjects included women with PCOS, menstrual irregularities and hyperandrogenism.ResultsA total of 33 studies were included in this review. Eighteen pre-clinical studies reported mechanisms of effect and fifteen clinical studies corroborated pre-clinical findings, including eight randomised controlled trials, and 762 women with menstrual irregularities, hyperandrogenism and/or PCOS. Interventions included herbal extracts of Vitex agnus-castus, Cimicifuga racemosa, Tribulus terrestris, Glycyrrhiza spp., Paeonia lactiflora and Cinnamomum cassia. Endocrine outcomes included reduced luteinising hormone (LH), prolactin, fasting insulin and testosterone. There was evidence for the regulation of ovulation, improved metabolic hormone profile and improved fertility outcomes in PCOS. There was evidence for an equivalent effect of two herbal medicines and the pharmaceutical agents bromocriptine (and Vitex agnus-castus) and clomiphene citrate (and Cimicifuga racemosa). There was less robust evidence for the complementary combination of spirinolactone and Glycyrrhiza spp. for hyperandrogenism.ConclusionsPreclinical and clinical studies provide evidence that six herbal medicines may have beneficial effects for women with oligo/amenorrhea, hyperandrogenism and PCOS. However the quantity of pre-clinical data was limited, and the quality of clinical evidence was variable. Further pre-clinical studies are needed to explain the effects of herbal medicines not included in this review with current clinical evidence but an absence of pre-clinical data.Electronic supplementary materialThe online version of this article (doi:10.1186/1472-6882-14-511) contains supple...

Tribulus terrestris L. (TT) (puncturevine) is a common weed that grows in many countries worldwide and in some places is considered as a noxious weed. The plant has been used in traditional Chinese and Indian medicines and is now considered as one of the most popular aphrodisiacs. It is known for its healing properties for sexual difficulties, impotence, and human and animal hormonal imbalance. It is also used as a sexual booster. Because of the plant’s active substances that can be used for curing sexual and other disorders, interest in it is increasing, and it is currently one of the most studied medicinal plants. The products and preparations manufactured from the aboveground plant parts are especially popular among athletes and people with health issues and diseases such as hormonal imbalance, sexual problems, heart problems, and various kidney and skin diseases. The aim of this review is a comprehensive and critical assessment of the scientific publications involving TT, with special reference to its chemical constituents and biological properties that may facilitate current understanding and future studies of this fascinating plant species. The objectives of this review were (1) to find knowledge gaps, (2) to discuss critically relevant publications and issues with materials and methods that may be prerequisites for contradictory results, and (3) to identify research and development areas. It was found that some of the studies on TT extracts as aphrodisiacs are controversial. A significant number of research publications claim that TT extracts and nutritional supplements containing TT improve muscle tone, have a common biostimulating effect, and improve spermogenesis. However, there are a growing number of publications that dispute these claims, as there are no empirical data on commonly accepted mechanisms of action. The main biologically active substances in TT are steroidal saponins, flavonoids, alkaloids, and lignan amides, the most studied being the steroidal saponins. Multiyear data on the metabolic profile of the species are generally lacking. There are a variety of methods used for extracting plant material, differences in methodologies and saponin analyses, and scientific instruments that were used. Lack of common standards could be a reason for differences in the pharmacological activity and composition of the TT preparations. Development of standard procedures and methods for collection of plant material and analyses are recommended. Selection and breeding efforts and agronomic studies of promising clones of TT would need to be conducted in order to develop TT as a new crop. This will provide consistency of supply and quality of the feedstock for the pharmaceutical industry and could provide a new cash crop for growers.

Diabetes existed as a global disease and people residing in cold temperature areas encounter synergetic effects resulting in exacerbation of diabetic impediments. In view of dearth in literature with respect to its synergistic actions, this study was intended to discover an interactive effect of co-induced diabetes and cold stress on female rat reproductive hormones and also to assess ameliorative role of both Tribulus terrestris fruit (TTF) extract. STZ induced (45mg/kg bw) diabetic rats were exposed to cold stress 4±2ºC to explore the alterations in female reproductive hormones. A group of experimental rats were supplemented with TTF and extract individually at doses of 150, 200, 250 mg/kg bw for 19 days respectively. Significant alterations occurred in the levels of gonadal hormones in experimental rats’ advocates exacerbation in toxicity due to cold stress. Both diabetes and cold stress alone found to decrease FSH, LH and estrogen levels significantly (P<0.05), while progesterone levels increased significantly. Contrary to supra, cold exposure to diabetic rats caused augmentations in FSH, LH and progesterone levels with decreased estrogen levels. Supplementation of both TTF extract was found to be advantageous in reinstating the altered gonadal hormones as witnessed in cold stressed diabetic rats. The ameliorative efficacy of phytoextract could be due to the additive/individual ability of polyphenols, flavonoids and steroidal saponins which are known for hormone regulatory actions and also antidepressant actions suggesting their therapeutic role in both cold stressed and diabetic population.
