Investigation of the role of herbal medicine, acupressure, and acupuncture in the menopausal symptoms: An evidence-based systematic review study

Background

Menopause is an important physiological phenomenon in women's lives. Women's concern about taking the hormone treatment to ease menopausal symptoms is increasing. Over the past decade, the use of complementary and alternative medicine for the treatment of menopausal problems instead of hormone therapy has increased.

Objective

This study aimed to investigate the role of herbal medicine, acupressure, and acupuncture in the menopausal symptoms.

Methods

Data source: related articles were searched from internal scientific databases and external databases of "Web of Scopus, Cochrane, PubMed, Science Direct, Ovid, and Google scholar."

Study Eligibility Criteria

The keywords such as menopause, menopausal symptoms, complementary menopausal medicine, acupuncture in menopause, herbal medicine in menopause, and acupuncture in menopause were searched in the studies from 1987 to 2019. Exclusion criteria were inadequate information in the study, lack of access to full-text articles, animal studies, and reports. At the end of the search, 145 articles out of a total of 400 articles were reviewed.

Results

In various studies, different herbs such as licorice, valerian, soy, sage, ginseng, etc., were used to improve menopausal symptoms. In addition, acupuncture and acupressure were used to reduce menopausal symptoms.

Conclusion

The efficacy and use of complementary and alternative medicine, along with other classical medicine care, can be a new model for improving menopausal symptoms in women. It is recommended that further clinical and review studies be conducted to develop complementary and alternative medicine.

The assessment of efficacy of Diascorea alata for menopausal symptom treatment in Taiwanese women

OBJECTIVE

The aim of this study was to assess the efficacy and safety of Diascorea alata for treatment of menopausal symptoms.

MATERIALS AND METHODS

Two-center, randomized, double-blind, placebo-controlled clinical investigation on 50 menopausal women randomly assigned to two groups, treated for 12 months with either placebo or two sachets daily of Diascorea extracts containing 12 mg/sachet. Primary outcome measures were changes in the Greene Climacteric Scale caused by Diascorea compared with placebo; secondary outcomes were changes in plasma hormone profiles. One-way ANCOVA test was performed to investigate the significance.

RESULTS

At 6 months and at the end of treatment, those women who received Diascorea showed general improvement in almost all the clinical symptoms investigated. A significant reduction was noted in the total Greene scores in the Diascorea group assessed at the end of 12 months' treatment (p < 0.01). This phenomenon was more significant for the psychological parameters of anxiety than for other parameters. Apparent improvements were noted in the parameters 'feeling tense or nervous' (p = 0.007), 'insomnia' (p = 0.004), 'excitable' (p = 0.047) and 'musculoskeletal pain' (p = 0.019) among those receiving Diascorea. Diascorea consumption also resulted in positive effects on blood hormone profiles.

CONCLUSIONS

Compared with placebo, Diascorea alata improves symptoms, particularly the psychological parameters in menopausal women. Safety monitoring indicated that standardized extracts of Diascorea alata were safe during daily administration over a period of 12 months.

Hormone replacement therapy

HRT should not be used for the prevention or treatment of chronic disease (eg, heart disease, osteoporosis, dementia). HRT is effective in alleviating moderate to severe menopausal symptoms. Clinicians must be aware of the risks and benefits of HRT and discuss them thoroughly with their patients. As new forms and lower doses of hormones become available, additional studies will be needed to compare therapeutic strategies adequately. Studies of younger perimenopausal and menopausal women are needed. Whatever regimen is chosen, the lowest allowable estrogen dose to relieve symptoms for the shortest time is recommended. Alternatives to hormonal therapy are being examined and some may be considered. Table 1 provides an evidence-based summary of current recommendations.

Nonestrogen Treatment Modalities for Vasomotor Symptoms Associated with Menopause

OBJECTIVE:

To systematically review the literature regarding the efficacy and safety of nonestrogen treatments for menopause-associated vasomotor symptoms not due to cancer or chemotherapy.

DATA SOURCES:

Pertinent literature and clinical studies were identified by searching MEDLINE (1966–February 2004) and EMBASE (1959–February 2004) using the key search terms vasomotor symptoms, hot flashes, and menopause. Bibliographies of relevant articles were reviewed for additional references.

STUDY SELECTION AND DATA EXTRACTION:

English-language articles reporting efficacy and safety of nonestrogen treatment modalities for perimenopausal and postmenopausal vasomotor symptoms were evaluated. All articles identified from the data sources were evaluated, and all information deemed relevant was included. Emphasis was placed on randomized, double-blind, placebo-controlled clinical trials, as these provide the best efficacy and safety data. Studies evaluating treatment of vasomotor symptoms from other causes, such as cancer or chemotherapy, were excluded.

DATA SYNTHESIS:

Prescription medications reviewed for efficacy and safety in postmenopausal vasomotor symptoms include clonidine hydrochloride, danazol, gabapentin, methyldopa, mirtazapine, progestins, propranolol hydrochloride, selective serotonin-reuptake inhibitors (SSRIs), and venlafaxine. Nonprescription therapies reviewed include black cohosh, dong quai, evening primrose oil, physical activity, phytoestrogens, and red clover.

CONCLUSIONS:

According to this systematic literature review, postmenopausal vasomotor treatments that have been shown to be safe and effective in short-term use include black cohosh, exercise, gabapentin, medroxyprogesterone acetate, SSRIs (ie, paroxetine hydrochloride), and soy protein. Initial, small reports are suggestive for efficacy in menopausal vasomotor symptoms with megestrol acetate and venlafaxine.

Perimenopausal and Postmenopausal Health

HEALTH ISSUE: The average age of natural menopause in Western societies is estimated to be 51 years; women in Canada can therefore expect to live, on average, a third of their lives in post-menopausal years. During these years women are at increased risk of chronic diseases such as osteoporosis and cardiovascular disease. KEY FINDINGS: Clinical and epidemiological data on women in perimenopause are limited. There are no adequate Canadian data on symptom severity and prevalence among perimenopausal and postmenopausal women. Scientific evidence is lacking to support or refute claims that commonly used botanical products can offer therapeutic relief of menopausal symptoms.Recent data from the Women's Health Initiative suggest that combined estrogen plus therapy increases the risk of stroke, coronary artery disease and breast cancer. Hormone therapy is no longer recommended for the prevention of chronic diseases for asymptomatic women. Stroke is an important issue for perimenopausal and postmenopausal women and sex differences may exist in the progestin treatment of stroke. Osteoporosis affects an estimated one in six women over the age of 50. DATA GAPS AND RECOMMENDATIONS: There is a need to conduct clinical and epidemiological research aimed at better understanding the menopausal transition and defining its clinical phases. Investigations aimed at alternative combinations and doses of hormone therapy and non-pharmaceutical alternatives in light of known risks and benefits are also necessary. Health care practitioners and women need to be educated on the risks and effective treatment related to cardiovascular disease so they can present for treatment more quickly and receive the most effective therapies.

CEU:Managing menopausal symptoms after the women's health initiative

Until the results of the Women's Health Initiative (WHI) were released in July 2002, hormone replacement therapy (HRT) had been thought to be the most effective way to manage unwanted menopausal symptoms and to prevent long-term health problems associated with aging. The results of the WHI, showing that HRT is less beneficial and associated with more risks than previously thought, has complicated the management of unwanted menopausal symptoms. This article discusses the effectiveness of HRT and other modalities used to relieve menopausal symptoms and discusses how to choose an HRT product to match specific menopausal complaints and provide maximum safety.

What we know about managing menopausal hot flashes: navigating without a compass

Hot flashes and night sweats are frequently experienced as the cardinal symptoms of menopause. However, their physiological basis has not been explained; nor have any potential risks been explored. Current knowledge and theoretical perspectives regarding hot flashes will be presented and contrasted with evidence for an emerging hypothesis of altered brain glucose availability as the hot flash trigger. Perspectives regarding hormone therapy and alternative therapies for treatment of hot flashes will be presented and directions for future research reviewed.

Fitoestrogênios: posicionamento do Departamento de Endocrinologia Feminina da Sociedade Brasileira de Endocrinologia e Metabologia (SBEM)

Para avaliar a utilidade dos fitoestrogênios (FE) na terapia de reposição hormonal da menopausa (TRHM), o Departamento de Endocrinologia Feminina da SBEM reuniu um grupo de especialistas para fazer uma revisão bibliográfica e selecionar trabalhos nos quais a metodologia adotada demonstrasse rigor científico. Os FE têm ações estrogênicas e antiestrogênicas, predominantemente sobre os receptores de estrogênios (E) beta, com potência estrogênica muito inferior à do estradiol. O conteúdo de FE nas suas fontes vegetais é variável, dependendo da forma de cultivo, safra, armazenamento e industrialização. Também a conversão dos precursores em fitormônios ativos no organismo humano tem grande variabilidade individual. A maior parte das pesquisas com FE é realizada in vitro ou com animais de laboratório, nem sempre podendo ser extrapoladas para humanos. Com relação à síndrome do climatério, alguns estudos sugerem discreta melhora dos fogachos, sem modificação do ressecamento vaginal ou das alterações do humor. No metabolismo lipídico, alimentação rica em soja, mas não isoflavonas isoladamente, promove redução do colesterol total, do LDL-col e dos triglicerídeos, mas não elevam o HDL-col, como os E, e podem causar aumento da lipoproteína (a), que os E contribuem para diminuir. Embora alguns estudos de curta duração sugiram aumento da densidade mineral óssea com uso de isoflavonas, não há demonstração de redução de fraturas. Conclui-se que não há evidências convincentes que justifiquem o uso de FE ou alimentação rica em soja como alternativa para a TRHM.

Use of alternative and complementary medicine in menopause

OBJECTIVES

To review the clinical evidence available for the treatment of menopausal symptoms with alternative and complementary medicine.

METHODS

The MEDLINE, PREMEDLINE and COCHRANE electronic databases for the years 1980-2002 were searched for articles concerning soy products, black cohosh, dong quai, acupuncture, ginseng and evening primrose oil. Studies pertaining to menopausal vasomotor symptoms, lipid profiles and bone mineral densities of postmenopausal women were included. The data from clinical trials were reviewed.

RESULTS

Soy isoflavones slightly decrease total cholesterol and LDL levels. The clinical significance of this small change is yet to be determined. The synthetic isoflavone derivative ipriflavone increases bone mineral density in healthy peri- and postmenopausal women with moderate bone mineral densities. Although earlier reports have claimed that soy is beneficial for the improvement of vasomotor symptoms, recent data do not support this claim. There are insufficient data on the other alternative therapies for treating menopausal symptoms at this time.

CONCLUSION

Alternative and complementary medicine may play a role in the management of menopause, however, well-designed large studies are still needed.
