October 6, 2025 •

4 min read

Phytoestrogens, plant-derived compounds that can mimic the body's natural estrogen, are found in various herbs commonly used for tea. This has led many to question, what tea increases estrogen levels naturally? This article explores several herbal teas associated with phytoestrogenic effects, examines the scientific evidence, and offers a balanced perspective for those interested in natural hormonal support.

Quick Summary

Certain herbal teas contain phytoestrogens, compounds that can mimic estrogen's effects, potentially helping balance hormones, particularly during menopause. Several options, including red clover, licorice root, and green tea, are noted for influencing hormonal activity. Effects vary, and consulting a healthcare professional is crucial before using these teas for hormonal purposes.

Key Points

Phytoestrogens mimic estrogen: Plant-derived phytoestrogens in certain teas can bind to the body's estrogen receptors, creating an estrogen-like or anti-estrogenic effect.
Red clover is a strong source: This tea contains high levels of isoflavones, a potent type of phytoestrogen, often used to help alleviate menopausal symptoms like hot flashes.
Licorice root regulates cortisol: It contains phytoestrogens and has adaptogenic properties that help regulate cortisol, the stress hormone, which can indirectly aid hormonal balance.
Green tea has complex effects: Research on green tea shows conflicting results, with short-term effects possibly lowering estrogen, but long-term consumption potentially increasing it in some postmenopausal women.
Chamomile has dual action: Though known for its calming properties, chamomile also contains phytoestrogens but can act as a selective estrogen receptor, impacting hormone levels in varying ways.
Consult a healthcare provider: Due to potential interactions with medications and specific health conditions, especially hormone-sensitive ones, it is crucial to consult a doctor before using these teas.

Understanding Phytoestrogens and Their Impact on Hormones

Phytoestrogens are a group of natural chemicals found in plants that can bind to the body's estrogen receptors, mimicking the effects of the hormone. This is a crucial distinction: they do not add human estrogen to your body but rather interact with existing hormonal pathways due to their similar chemical structure. Depending on the specific phytoestrogen and individual factors, this interaction can either have a weak estrogenic effect or, in some cases, an anti-estrogenic effect. The potential benefits of these compounds, such as reducing menopausal symptoms or supporting bone health, have been the subject of extensive research. However, it is essential to approach herbal remedies with caution and informed knowledge, as their effects can be complex and are not universally beneficial for everyone. The efficacy can be influenced by an individual's gut bacteria, overall health, and age.

Herbal Teas Associated with Phytoestrogenic Effects

Several herbal teas have gained a reputation for their ability to influence hormonal balance, primarily due to their phytoestrogen content. It is important to note that the strength and nature of these effects vary by herb and depend on consistent consumption.

Red Clover Tea

Red clover (Trifolium pratense) is one of the most well-known sources of isoflavones, a type of phytoestrogen. Because its isoflavones produce estrogen-like effects, red clover tea is frequently used to help manage menopausal symptoms such as hot flashes and night sweats. Some research also suggests it may support bone health in postmenopausal women. As with many herbal remedies, consistency is key, and individual results can vary.

Licorice Root Tea

Licorice root (Glycyrrhiza glabra) contains plant compounds that can mimic estrogen, making it another popular choice for hormonal support. Beyond its estrogenic properties, licorice root is also known for its adaptogenic qualities, which help the body adapt to stress by regulating cortisol levels. This can be particularly beneficial for people with adrenal fatigue or hormonal imbalances exacerbated by stress. However, regular consumption can raise blood pressure, so it should be used with caution, especially for those with hypertension.

Green Tea

Green tea, derived from the Camellia sinensis plant, has a complex relationship with estrogen levels. Its potent antioxidant compounds, like epigallocatechin gallate (EGCG), can influence estrogen metabolism. Interestingly, studies have shown conflicting results regarding its effect on estrogen. Some research suggests green tea can modify estrogen metabolism, with potential short-term effects of lowering estrogen levels, but long-term use (over 20 years) may lead to a feedback mechanism that increases estradiol concentrations in postmenopausal women. This highlights the complexity and variability of how herbs interact with the body's endocrine system.

Chamomile Tea

Chamomile tea is widely recognized for its calming properties, which can indirectly support hormonal health by reducing anxiety and improving sleep. It also contains phytoestrogens that can act like estrogen in the body, potentially helping to alleviate menopausal symptoms like hot flashes. However, some studies have also indicated antiestrogenic properties, demonstrating that chamomile can act as a selective estrogen receptor. The dual nature of its effects means it should be used thoughtfully and not as a direct replacement for medical treatment.

Fennel Seed Tea

Fennel seeds are another source of phytoestrogens and have been used to support digestion and menopausal symptoms. Like other phytoestrogen-rich herbs, they can help alleviate hot flashes and support hormonal balance during transitions like menopause. Fennel also provides antioxidants and may help support gut health, which is a factor in overall endocrine function.

Comparison of Phytoestrogenic Teas

To help clarify the differences between these herbal remedies, here is a comparison of their hormonal effects and primary uses.


Tea	Primary Hormonal Effect	Key Benefits	Notable Considerations
Red Clover	Strong phytoestrogenic properties	Alleviates hot flashes, supports bone health during menopause	Consistency is required; individual results vary
Licorice Root	Adaptogenic, mildly phytoestrogenic	Reduces stress (cortisol), offers potential estrogenic benefits	Can raise blood pressure with regular use; consult doctor
Green Tea	Complex, antioxidant-driven influence on metabolism	Antioxidant support, improved metabolism	Effects on estrogen vary; long-term use may differ from short-term
Chamomile	Mildly phytoestrogenic or antiestrogenic	Promotes relaxation, sleep; may ease menopausal symptoms	Can act as a selective estrogen receptor; not for direct hormone replacement
Fennel Seed	Phytoestrogenic	Aids digestion, reduces menopausal hot flashes	Generally considered safe, but effects can be mild

Considerations and Potential Risks

Before incorporating any tea with hormonal effects into your routine, it is vital to consider potential risks and interactions. While herbal teas are often seen as gentle, their compounds can have powerful physiological effects.

Interactions with Medications: Herbs can interact with hormonal medications, blood pressure medication, and blood thinners. Always consult a healthcare provider, especially if you are on prescription drugs.
Hormone-Sensitive Conditions: People with hormone-sensitive conditions, such as certain types of breast, uterine, or ovarian cancer, should be extremely cautious with phytoestrogenic herbs and discuss any changes with their doctor.
Dosage and Duration: The effective dose and optimal duration of use for herbal teas are not standardized. Many studies are based on long-term, consistent use, which may yield different results than short-term consumption. Side effects like stomach upset or allergic reactions can occur.

Conclusion: A Holistic Approach to Hormonal Balance

While certain teas contain compounds known as phytoestrogens that can mimic the effects of estrogen, they should not be viewed as a standalone solution for managing hormone levels. The scientific evidence is complex, with effects varying based on the herb, individual biochemistry, and duration of use. Teas like red clover, licorice root, green tea, chamomile, and fennel seed all have unique properties that may influence hormonal balance, but they also carry specific considerations and potential risks. An herbal remedy, like a diet or exercise regimen, should always be discussed with a healthcare professional to ensure it is appropriate for your individual health profile and does not interfere with existing treatments. Combining these teas with a balanced diet and a healthy lifestyle is the most prudent approach to supporting overall well-being and hormonal health.
