Effect of chamomile capsule on lipid- and hormonal-related parameters among women of reproductive age with polycystic ovary syndrome

Could polyphenols be an effective treatment in the management of polycystic ovary syndrome?

Polycystic ovary syndrome (PCOS), is a health problem observed in women of reproductive age. Different diets, physical activity recommendations and lifestyle changes can be effective in dealing with the symptoms of PCOS. Nutrition is indeed an essential part of the treatment of the disease as it directly affects body weight loss, insulin resistance, lipid profile, hormones, and dermatological complaints such as acne. Polyphenols, simply classified as flavonoids and non-flavonoids, are bioactive components found in plant-based foods. The most common polyphenols in the diet are flavanols, flavonols, flavanone, anthocyanins. In particular, polyphenols which are compounds naturally found in foods, have antioxidant, anticancer, anti-inflammatory, antimutagenic benefits along with many other ones. In the treatment of PCOS, polyphenols may help reduce the symptoms, improve insulin resistance and poor lipid profile, and cure hormonal disorders. It has been reported that polyphenols are influential in menstrual cycle disorders and enable a decrease in body weight, hyperandrogenism, estrogen, testosterone, luteinizing hormone (LH)/follicle stimulating hormone (FSH) ratios and LH. For adequate daily intake of polyphenols, which are found in high amounts in fruits and vegetables, at least 5 portions of fruits and vegetables should be consumed in addition to a healthy nutrition pattern. In this review, the effects of various polyphenols on polycystic ovary syndrome are discussed.

Effects of natural products on polycystic ovary syndrome: From traditional medicine to modern drug discovery

Polycystic Ovary Syndrome (PCOS) is a common endocrine disorder with a worldwide prevalence of 6-10 % of women of reproductive age. PCOS is a risk factor for cardiometabolic disorders such as type 2 diabetes, myocardial infarction, and stroke in addition to exhibiting signs of hyperandrogenism and anovulation. However, there is no known cure for PCOS, and medications have only ever been used symptomatically, with a variety of adverse effects. Drugs made from natural plant products may help treat PCOS because several plant extracts have been widely recognized to lessen the symptoms of PCOS. In light of this, 72 current studies on natural products with the potential to control PCOS were examined. By controlling the PI3K/AKT signaling pathway and decreasing NF-κB and cytokines such as tumor necrosis factor (TNF), interleukin-1 (IL-1), and interleukin-6 (IL-6), certain plant-derived chemicals might reduce inflammation. Other substances altered the HPO axis, which normalized hormones. Additionally, other plant components increased glutathione (GSH), superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) levels to reduce radiation-induced oxidative stress. The other substances prevented autophagy by impairing beclin 1, autophagy-related 5 (ATG5), and microtubule-associated protein 1A/1B-light chain 3 - II (LC3- II). The main focus of this comprehensive review is the possibility of plant extracts as natural bio-resources of PCOS treatment by regulating inflammation, hormones, reactive oxygen species (ROS), or autophagy.

Chamomile and Urtica dioica extracts improve immunological and histological alterations associated with polycystic ovarian syndrome in DHEA -induced mice

BACKGROUND

One of the novel mechanisms in the pathogenesis of Polycystic ovary syndrome (PCOS) is low-grade chronic inflammation. Chamomile (Matricaria recutita L.) and Nettle (Urtica dioica), with phytoestrogenic and antioxidant properties, are traditionally used to treat gynecological diseases. This study investigated the immune-modulating effects of these two plants.

METHODS

Following the induction of PCOS by subcutaneous injection (SC) of Dehydroepiandrosterone (DHEA) in BALB / C mice. Mice were treated in five groups: Sham, PCOS, PCOS + Chamomile, PCOS + Nettle, and PCOS + Chamomile and Nettle for 21 days. Ovarian morphology, blood antioxidant capacity, the abundance of Treg cells, and expression of matrix metalloproteinase-9 (MMP-9), transforming growth factor-ß (TGF-ß), cyclooxygenase-2 genes (COX-2), and tumor necrosis factor-alpha (TNF-α) were measured.

RESULTS

Folliculogenesis, Cystic follicles, and corpus luteum improved in the treatment groups (P < 0. 05). Treg cells in the DHEA group were significantly reduced compared to the Sham group (P < 0. 01). However, this decrease was not corrected in treatment groups (P > 0. 05). Total serum antioxidant capacity was significantly increased in the treatment group of Nettle and Chamomile + Nettle (P < 0. 05). The expression of MMP9 and TGFβ genes in the PCOS group was significantly higher than the Sham group (P < 0. 05), which the expression of MMP9 was corrected by treatment with Chamomile + Nettle extract (P < 0. 05).

CONCLUSION

Chamomile and Nettle extract may be an effective supplement in improving the histological and immunological changes of PCOS. However, more research is needed to confirm its effectiveness in humans.

Chinese herbal medicine alleviates the pathogenesis of polycystic ovary syndrome by improving oxidative stress and glucose metabolism via mitochondrial Sirtuin 3 signaling

BACKGROUND

Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders among women, and the curative effects of its current management are not satisfactory. A formula of Chinese herbal medicine (CHM), called Bu-Shen-Tian-Jing Formula (BSTJF), has clinically shown beneficial effects in treating PCOS.

PURPOSE

This study aimed to investigate the mechanism underlying BSTJF for treatment of PCOS.

METHODS

Whole blood samples were collected from women with PCOS treated and not treated with BSTJF (n = 5 per group). Whole transcriptome sequencing of leukocytes and untargeted metabonomic analysis of the plasma were performed. Three groups of 18 female Sprague-Dawley rats were randomly selected: control, PCOS, and BSTJF. A PCOS rat model was established using testosterone propionate. The estrous cycle; glucose tolerance; ovarian morphology; serum markers of oxidative stress; and expression of Sirtuin 3 (SIRT3), phospho-p38 mitogen-activated protein kinase, phosphatidylinositol 3-kinase (PI3K), and phospho-protein kinase B in the ovary were measured. Palmitate was initially applied to KGN cells, followed by freeze-dried BSTJF powder. The glucose uptake, reactive oxygen species (ROS) production, and protein levels of SIRT3, PI3K, and glucose transporter type 4 (GLUT4) were detected in KGN cells.

RESULTS

The transcriptomic and metabolomic profiles showed alterations in 572 genes and 73 metabolites in women with PCOS treated with BSTJF. The enriched pathways in women with PCOS treated with BSTJF were mainly involved in inflammation, insulin resistance, glucose and lipid metabolism, and neuro and associated signaling pathways. In PCOS rat models, BSTJF improved the estrous cycle, glucose tolerance, and ovarian morphology; relieved oxidative stress; increased ovarian SIRT3 expression; inhibited p38 MAPK activation; and promoted the activation of PI3K/AKT signaling in the ovary. In the in-vitro study with KGN cells, BSTJF rescued the palmitate-induced impaired glucose uptake and SIRT3 expression, reduced mitochondrial ROS production mediated by SIRT3, and restored the impaired insulin-induced PI3K/AKT signaling pathway.

CONCLUSION

BSTJF effectively alleviated the pathogenesis of PCOS by improving oxidative stress and glucose metabolism via mitochondrial SIRT3 and the following insulin signaling pathway. This study innovatively revealed the action mechanism of CHM in treating PCOS.

The Protective Effects of Trans-Anethole against Polycystic Ovary Syndrome Induced Histopathological and Metabolic Changes in Rat

Aim of the study was to evaluate the protective effects of trans-anethole, against polycystic ovary syndrome (PCOS) induced histopathological and biochemical changes in female Wister rats.<br />Materials and Methods: In this experimental study, forty-eight animals were randomly assigned into 6 groups: control; PCOS; PCOS+trans-anethole (20, 40, 80 mg/kg); and PCOS+metformin (300 mg/kg). Testosterone (1 mg/kg/day) was injected intraperitoneally for 35 days to induce PCOS. After PCOS induction, animals were treated by transanethole and metformin (30 days oral gavage). Finally, serum oxidative stress and insulin levels as well as histological changes in ovaries, kidneys and liver were evaluated.<br />Results: In PCOS group, the serum level of malondialdehyde (MDA) was 1.391 ± 0.18 mmol/L and significantly<br />increased (P=0.000) compared to the control group with the MDA level of 0.35 ± 0.08. Meanwhile the activity of<br />superoxide dismutase (SOD) and catalase (CAT), and total thiol levels were significantly decreased (P=0.000 for all<br />groups), compared to the control group. In the trans-anethole (80 mg/kg) treated group, insulin (P=0.000) and MDA<br />(P=0.000) levels were significantly decreased while total thiol (P=0.001) and activity of SOD (P=0.000) and CAT<br />(P=0.007) were significantly increased compared to the PCOS group. In the metformin treated group the insulin level<br />(P=0.03) decreased compared to the PCOS group. Histological evaluation showed multiple cysts in the ovarian tissue,<br />an increase in inflammatory cells in the liver, and a loss of order in the structure of the tubules and glomeruli of the<br />kidney in the PCOS group. Tissue damage was reduced in the trans-anethole treated group.<br />Conclusion: Tarns-anethole at a dose of 80 mg/kg improved metabolic status, oxidative stress, liver and kidney damage<br />as well as the cystic mass of ovarian tissue. To understand the exact protective effects of trans-anethole in PCOS,<br />more experimental or clinical studies are suggested.

Background:

Complications of hormone therapy (as replacement) during menopause prompted us to research on alternative therapies including herbal therapy in this regard.

Objectives:

The effect of Salvia officinalis extract on symptoms of flushing, night sweat, sleep disorders, and score of forgetfulness in postmenopausal women on Namazi Hospital Bone Density Center in Shiraz 2015.

Methods:

In a double-blind randomized controlled clinical trial, 66 postmenopausal women complaining of menopausal symptoms were divided into two groups of intervention and control, respectively. The intervention group received S. officinalis tablets (containing 100 mg S. officinalis extract), with a dose of three tablets a day for 3 months, while the control group received placebo tablets with the same prescription order. MRS (Menopause Rating Scale) and PSQI (Pittsburgh Sleep Quality Index) questionnaires were completed at the beginning and end of the study. The checklists of hot flushing and night sweating were completed a week before the intervention and at weeks 2, 4, 6, 8, 10, 12 during the intervention. Finally, the data were analyzed through SPSS₁₈ software, using paired t-test, ANOVA. A significant level of 5% was considered.

Results:

According to the paired t-test, the mean score of flushing, palpitation, sleeping disorders, muscle and joint aches, depression, nervousness, anxiety, and sexual desire and satisfaction significantly decreased by 1.6, 0.4, 1.6, 2.1, 1.4, 1.2, 1.6, and 0.8 units, respectively, in the intervention group compared to the control group (P < 0.001). Therefore, the mean score of PSQI significantly decreased by 3.8 units in the intervention group after the intervention (9.4 ± 3.7 vs 5.6 ± 1.9 (P < 0.05).

Conclusions:

Salvia extract improved menopausal symptoms such as flushing, night sweat, heart palpitations, muscle and joint pain, depression, anxiety, sleep disorders, and sexual desire.

Both Matricaria chamomilla and Metformin Extract Improved the Function and Histological Structure of Thyroid Gland in Polycystic Ovary Syndrome Rats through Antioxidant Mechanism

There is increasing proof that polycystic ovary syndrome (PCOS) is associated with the increased frequency of thyroid disturbances. Chamomile (Matricaria chamomilla L.) herb and metformin showed therapeutic efficacy against polycystic ovary syndrome (PCOS). This study aimed to investigate the possible therapeutic effect of both chamomile flower extract and metformin against thyroid damage associated with PCOS in rats. The PCOS model was developed in rats by injecting estradiol valerate, and it was confirmed to be associated with thyroid hypofunction biochemically and pathologically. Treatment of PCOS rats with both chamomile extract and metformin resulted in an improvement in serum level of thyroid hormones (TSH, p < 0.01; T3 and T4, p < 0.05) and the disappearance of most thyroid gland pathological changes demonstrated by light and electron microscopes. They also reduced the level of serum estrogen (p < 0.01). Both chamomile extract and metformin decreased MDA (p < 0.05) and increased GPx and CAT (p < 0.01). Only chamomile extract increased GSH (p < 0.01). Both treatments reduced the apoptotic death of thyroid cells as noted by the reduction of caspase-3 immunoexpression (p < 0.01). In conclusion, both Matricariachamomilla extract and metformin ameliorated hypothyroidism associated with PCOS through an antioxidant and antiapoptotic mechanism.

A comprehensive review of clinical studies with herbal medicine on polycystic ovary syndrome (PCOS)

BACKGROUND

Polycystic ovary syndrome (PCOS) is a frequent medical condition characterized by both metabolic and reproductive disorders. Different pharmaceutical treatments have been proposed for PCOS. However, side effects of long-term treatments and their probable low efficacy have made complementary and alternative treatments a valuable option. Recent reports have indicated the increased use of complementary treatments. Herbal medicine, as part of complementary medicine, was find introduced in traditional Persian and Chinese medicine. Medicinal herbs have used for a long time in the treatment of gynecological and infertility problems of PCOS patients. In this study, we aimed to review herbal medicines used for PCOS worldwide.

METHODS

PubMed, Embase, Cochrane, and Scopus databases were searched for clinical trials and Randomized Controlled Trials based on related keywords. Data were collected from 1990 to 2019.

RESULTS

According to a multitude of studies, a wide spectrum of herbs can be used to improve various aspects of PCOS. Herbs such as Cinnamomum verum, Trigonella foenum-graecum L., and Vitex agnus-castus can impact on menstrual and ovulatory dysfunctions, obesity, insulin resistance, lipid-metabolism dysfunction, and androgen excess-related conditions.

CONCLUSION

Some plants as natural remedies may have beneficial effects on improving different aspects of PCOS; but further studies are needed to investigate their mechanisms and safety.

The effect of aromatherapy on mental, physical symptoms, and social functions of females with premenstrual syndrome: A randomized clinical trial

Objective:

This study was designed to compare the effect of aromatherapy with Rosa Damascena and Citrus Aurantium blossom on psychological and physical symptoms and social functions of females with premenstrual syndrome.

Materials and Methods:

This double-blind clinical trial was conducted on 95 students. They were randomly divided into three aromatherapy groups (aromatherapy with 4% concentration of Rosa Damascena and 0.5% concentration of Citrus Aurantium blossom essential oil) and aromatherapy with sweet almond oil (as control group). Premenstrual Symptoms Screening Tool questionnaire (PSST) was completed before and during the first and second month of the intervention. Data were analyzed by SPSS software version 22.

Results:

After intervention, the scores of mental symptoms decreased in all three groups and this decrease was significant in both Citrus Aurantium (P = 0.004) and Rosa Damascena groups (P = 0.007). The score of physical symptoms was decreased in all three groups but it was significant only in the Rosa Demecensa group (P = 0.042). The reduction of effect of symptoms on social function was observed in two intervention groups which were significant only in Rosa Damascena group (P < 0.001).

Conclusion:

Essential oils of Rosa Damascena and Citrus Aurantium were both effective in improving the symptoms of premenstrual syndrome but the effect of Rosa Damascena, with regard to improvement of symptoms of premenstrual syndrome was more than that of Citrus Aurantium in all psychological, physical, and social aspects.

The glucose metabolism disorder and dyslipidemia among girls with different phenotype polycystic ovary syndrome

Background:

This study aimed to determine the prevalence of glucose metabolism disorder and dyslipidemia in 14–18-year-old girls with different phenotype polycystic ovary syndrome (PCOS).

Materials and Methods:

This descriptive, cross-sectional study was conducted on 3200 high-school adolescents aged 14–18 years in Shiraz in 2010. Selected parameters of metabolic syndrome (fasting blood glucose, glucose tolerance test [GTT], insulin level, triglyceride (TG), cholesterol, and high-density lipoprotein [HDL]), based on adult treatment panel Ш definition criteria, were compared between the “PCOS” and control groups.

Results:

Results were compared at four main phenotypes. The level of serum TG was increased in the Phenotype B (P = 0.03) and Phenotype D (P = 0.01), compared to the control group. Cholesterol and low-density lipoprotein levels (P < 0.05) and GTT (P > 0.05) were increased, and HDL was decreased (was below 50) in all the four phenotypes and the control group (P > 0.05).

Conclusion:

The risk of metabolic alterations of glucose metabolism disorder and dyslipidemia in PCOS adolescents was more than non-PCOS counterparts.
