What is Ashwagandha?
Ashwagandha (Withania somnifera) is an Ayurvedic herb with a long history of use. It has been modernized as a standardized extract, chosen by many women for its promise of stress reduction and energy enhancement. This text presents its origins, mechanisms, and major clinical applications to better understand its potential benefits and risks.
Botanical origin
Withania somnifera belongs to the Solanaceae family and is documented in traditional Indian medicine as a "rasayana" medicine with a systemic restorative effect.
Traditional use
The herb is classified as an adaptogen, used to support the nervous system, increase the ability to adapt to stress, and improve overall health.
Pharmacology
The main active pharmaceutical components include steroidal lactones (withanolides) and alkaloids; the mechanism of action involves modulating the HPA axis, influencing cortisol and neurotransmitters.
Clinical uses
Currently, ashwagandha is commonly used to treat stress and sleep disorders, improve physical performance, and support physiological function.
Evidence (thyroid)
Several clinical studies have reported that ashwagandha may alter TSH, T3, and T4 levels, which is particularly significant for women monitoring thyroid function.
Hormonal Effects in Women
Ashwagandha exerts significant effects on the female endocrine system through various biological mechanisms. The active ingredient withanolides can regulate important endocrine axes, from the thyroid to the ovaries, creating a comprehensive change in hormonal balance.
Thyroid regulation
Ashwagandha can stimulate thyroid activity and increase the synthesis of T3 and T4 hormones, improving basal metabolism and affecting the body's energy.
Reproductive hormones
Some clinical evidence notes an increase in free testosterone and improved estradiol levels in women, which are related to reproductive function and sexual desire.
Cortisol balance
This herb reduces plasma cortisol levels, thereby supporting the HPA axis and limiting chronic stress, a factor that often affects the menstrual cycle.
Clinical implications
These endocrine changes could be applied to support reproductive health, cyclical disorders, and energy regulation in women.
Risks During Pregnancy and Breastfeeding
Ashwagandha poses significant risks for pregnant and breastfeeding women. The potent bioactives may act directly on uterine smooth muscle and the endocrine system, leading to serious consequences for pregnancy and infant development.
Miscarriage risk
Animal studies and limited clinical reports suggest that ashwagandha may stimulate uterine contractions, increasing the risk of miscarriage or premature birth.
Lactation safety
Data on safety during breastfeeding are limited; the active compounds may be excreted in breast milk, potentially affecting the infant.
Hormonal interference
The herb may modulate estrogen and progesterone levels, altering important hormonal cycles during pregnancy and milk production.
Clinical guidance
Pregnant or lactating women should be closely monitored if considering use, with safer alternatives preferred.
Digestive and Gastrointestinal Side Effects
Ashwagandha can significantly affect the digestive system, especially in sensitive or gastrointestinal-disordered women. Its powerful bioactives act directly on the gastric mucosa and intestinal motility, leading to a wide range of clinical manifestations.
Nausea and vomiting
Many women report nausea or vomiting after taking ashwagandha extracts, which is related to gastric irritation and effects on the vomiting center in the brain.
Diarrhea and abdominal discomfort
This herb can increase intestinal motility, causing diarrhea or abdominal cramps, especially when taken in high doses or in combination with other stimulants.
Gut sensitivity
Women with irritable bowel syndrome (IBS) or peptic ulcers are at greater risk of severe reactions, characterized by bloating, indigestion, and acute gastrointestinal upset.
Clinical advice
Careful monitoring and starting with a low dose help reduce the risk of digestive side effects. Also, choose the extract form appropriate for your individual health condition.
Mental Health Considerations
Ashwagandha has a powerful effect on the central nervous system and HPA axis, producing a marked effect on women's mood. Its beneficial effects on regulating cortisol, neurotransmitters, and stress levels can also cause overreactions in sensitive individuals.
Anxiety modulation
This herb can reduce stress and anxiety by modulating GABAergic activity, but high doses can lead to feelings of overstimulation or nervousness.
Interaction with antidepressants
Ashwagandha may interact with antidepressants, benzodiazepines, or sedatives, altering the effectiveness of the treatment or increasing neurological side effects.
Sleep impact
Some women experience deeper sleep, while others report nightmares or difficulty sleeping due to the mild stimulant effect.
Clinical guidance
Monitoring psychological symptoms and working with a specialist can help optimize benefits, reduce the risk of side effects, and avoid unwanted drug interactions.
Autoimmune and Thyroid Conditions
Ashwagandha has a powerful effect on the immune system and thyroid function, which has important implications for women with autoimmune or endocrine disorders. The active ingredient withanolides acts directly on cytokines and thyroid hormones, leading to immune function and metabolism alterations.
Autoimmune modulation
The herb can stimulate the immune response, increasing cytokine production and lymphocyte activation, potentially triggering flares of autoimmune diseases such as lupus, rheumatoid arthritis, or Hashimoto's.
Hyperthyroidism risk
Ashwagandha promotes T3 and T4 synthesis, leading to increased basal metabolism; women with hyperthyroidism may experience tachycardia, anxiety, tremor, and insomnia.
Clinical implications
Regular medical monitoring and dosage adjustments help reduce the risk of adverse effects, while providing a safe basis for considering herbal supplements in sensitive populations.
Drug Interactions Specific to Women
Ashwagandha has the potential for complex drug interactions, particularly affecting women who are taking hormonal medications, thyroid medications, or oral contraceptives. These interactions involve hormone regulation, liver enzymes, and drug metabolism.
Birth control interference
The herb may interfere with the effectiveness of hormonal contraceptives due to its ability to alter estrogen and progesterone levels, which may affect menstrual cycle regularity and contraceptive effectiveness.
Thyroid medication interactions
Ashwagandha increases T3 and T4 hormone levels, which may alter the effects of levothyroxine or other thyroid medications, requiring dosage adjustments.
Hormone-related drugs
The herb interacts with other hormone-regulating medications, including hormone replacement therapy or osteoporosis medications, affecting clinical efficacy and potential side effects.
Clinical guidance
Women should seek medical advice before combining ashwagandha with any hormonal or endocrine medications to ensure safety and optimize therapeutic effects.
Dosage and Safety Guidelines
Ashwagandha should be used according to the dosage and medical instructions to ensure safety, especially for women with a history of endocrine or immune disorders or who are pregnant and breastfeeding. Appropriate dosage helps to optimize benefits while minimizing side effects.
Recommended dosage
The recommended dose ranges from 300–600 mg of a standardized extract with 5% withanolides per day; the dose should be divided into 1–2 doses to effectively absorb and reduce the risk of gastrointestinal disorders.
Monitoring and supervision
Regular clinical monitoring, including thyroid hormone testing, liver and kidney function assessment, and checking for signs of gastrointestinal or neurological disorders, is necessary to adjust the dose promptly.
Form selection
Choose a standardized extract form; avoid the raw powder form if there is a history of gastrointestinal sensitivity. Combination with other foods or drugs should be considered to reduce interactions.
Clinical guidance
Consulting with a health care professional before starting or adjusting dosage helps ensure safety, maximize benefits, and minimize risks for women.
Conclusion
Ashwagandha has many potential benefits for women's health, from stress reduction to improved sleep and support for sexual function. These benefits stem from its ability to regulate hormones, impact the HPA axis, and affect the immune system.
However, its powerful effects also come with significant risks. Before using it, women should consider factors such as thyroid, autoimmune disease, pregnancy, breastfeeding, and digestive health.
