Menopause, a natural transition in a woman's life, is characterized by the cessation of menstruation and ovarian function. This phase, while natural, often brings a range of symptoms that can significantly impact a woman's health and quality of life. As the population of menopausal and postmenopausal women is projected to reach 1.2 billion by 2030, with an estimated 85% experiencing menopause-related symptoms, the need for effective and safe management strategies becomes increasingly important. These symptoms, stemming from estrogen deficiency, include not only physiological dysfunctions like hot flashes, night sweats, and vaginal dryness but also psychological symptoms such as anxiety, depression, and irritability.
Hormone replacement therapy (HRT) has been a common medical approach to alleviate these symptoms and prevent bone loss. However, concerns about potential risks, including cardiovascular diseases and breast cancer, have led many women to seek alternative therapies, particularly plant-based options like soy isoflavones and other phytoestrogens. Among these, ashwagandha, also known as Withania somnifera, has gained attention for its potential benefits in managing menopause symptoms and promoting overall well-being.
Understanding Ashwagandha
Ashwagandha, also known as Indian ginseng and winter cherry, is a revered herb in Ayurveda, a traditional Indian system of medicine. Originating in India and thriving in dry, hot climates, including northern Africa and the Mediterranean, ashwagandha has been used for thousands of years for its diverse therapeutic properties and health benefits. Typically, the root of the ashwagandha plant is dried and ground into a powder, which can be used in beverages, capsules, tablets, and liquid extracts. While its traditional uses are well-established, modern research is only beginning to explore its full potential. Smaller human and test-tube studies have shown promise, but larger clinical trials are needed to confirm these benefits.
Some consider ashwagandha an adaptogen, a substance believed to help the body adapt to various kinds of stress. While the concept of adaptogens is theoretical and lacks conclusive evidence, ashwagandha's potential to balance hormones can be particularly beneficial for women's health, impacting aspects such as the menstrual cycle, reproduction, and menopause. Research suggests that ashwagandha influences the endocrine system, which governs mood, stress responses, and reproduction, potentially aiding in hormonal imbalances and related issues like anxiety, depression, and sleep disturbances.
Ashwagandha's Potential Benefits for Menopause
One of the key areas where ashwagandha shows promise is in alleviating menopause symptoms. A 2021 study in women experiencing perimenopause found that taking 300 mg of ashwagandha root extract twice daily for 8 weeks significantly enhanced the quality of life associated with menopause and reduced physical, psychological, and urogenital symptoms compared to a placebo. The study also noted an increase in serum estradiol and a significant decrease in serum follicle-stimulating hormone (FSH) and luteinizing hormone (LH) levels.

Impact on Specific Menopause Symptoms
- Mood and Psychological Well-being: Ashwagandha's mood-boosting potential can help cultivate calmness by alleviating anxiety, depression, and irritability. Its adaptogenic properties may help the body deal with stress and maintain balance.
- Hormone Regulation: Ashwagandha consumption increased serum estradiol and significantly decreased serum FSH and LH. By regulating hormone levels, optimizing ovarian function, and enhancing overall well-being.
- Urogenital Symptoms: Ashwagandha intake demonstrated a statistically significant reduction in total MENQoL scores (p < 0.0001) and was also associated with a statistically significant increase in serum estradiol (p < 0.0001) and a significant reduction in serum FSH (p < 0.0001) and serum LH (p < 0.05) compared with the placebo.
- Sexual Wellness: Ashwagandha has aphrodisiac qualities that may enhance libido and overall sexual wellness, potentially due to its ability to uplift mood and reduce stress. A 2023 review in healthy women found that consuming ashwagandha root extract positively impacts sexual function, increasing lubrication, orgasm, and sexual arousal scores.
Research on Ashwagandha and Other Herbal Combinations
A 24-week study investigated the effects of dietary supplementation with standardized aqueous extracts of Asparagus racemosus (Ar), commonly known as shatavari, and Withania somnifera (Ws), or their combination, on reducing menopause symptoms, vascular dysfunction, bone turnover, and serum concentrations of inflammatory and oxidative stress markers among postmenopausal women. The study found that supplemented groups showed a significant dose-dependent decrease in menopause-specific quality of life (MENQOL) and reflection index (RI) compared with placebo. Women supplemented with Ws or Ar extracts had significantly decreased levels of bone turnover markers and increased osteoprotegerin levels.
Considerations and Potential Risks
While ashwagandha offers potential benefits, it's important to be aware of potential risks and considerations:
- Allergies and Intolerance: As a nightshade, ashwagandha may cause symptoms in individuals with nightshade intolerance. Allergic reactions are also possible.
- Increased Thyroxine Levels: Case studies have reported thyrotoxicosis in people taking ashwagandha supplements, indicating that it may stimulate thyroxine production.
- Contamination with Heavy Metals: Due to the lack of regulation by the FDA, ashwagandha products may be contaminated with heavy metals. It is advisable to look for herbal products that have undergone third-party testing to prove they are safe.
- Drug Interactions: Ashwagandha may interact negatively with substances that act on the GABA system, such as anticonvulsants, benzodiazepines, and barbiturates. It may also interfere with the metabolism of other drugs.
- Withdrawal Symptoms: Anecdotal reports suggest that stopping ashwagandha may cause withdrawal symptoms, so gradually tapering down the dosage may be advisable.
- Not a Substitute for Medical Care: Ashwagandha is not a substitute for medical care, and relying on it may delay necessary medical attention.
Individuals who are pregnant or could become pregnant, are taking certain medications, or have certain health conditions should not take ashwagandha.
