Historical and Traditional Uses of Clover
For centuries, different cultures have utilized various species of clover, most notably red clover (Trifolium pratense) and white clover (Trifolium repens), for their perceived health benefits. Native American tribes used it to treat ailments ranging from burns and respiratory issues to fevers. European herbalists also employed clover for its 'blood-purifying' properties and to address skin conditions like eczema and psoriasis. In Russia and parts of Asia, it has been used as a diaphoretic (sweat-inducing) and expectorant for colds.
The Active Compounds in Clover
Clover’s therapeutic potential is largely attributed to its rich composition of active compounds. These include:
- Isoflavones: These are a class of phytoestrogens, plant-based compounds that can mimic estrogen in the body. Red clover has been extensively studied for its isoflavone content, which includes genistein, daidzein, formononetin, and biochanin A.
- Polysaccharides and Flavonoids: These act as powerful antioxidants, protecting the body from oxidative stress and inflammation.
- Essential Nutrients: White clover, in particular, is a source of essential vitamins and minerals, including Vitamins A, C, E, K, calcium, magnesium, and potassium.
Clover's Benefits for Women's Health
One of the most researched areas of clover's effect on humans, especially red clover, is its impact on women’s health, particularly during menopause. The isoflavones it contains can help regulate hormonal fluctuations.
Menopausal Symptom Relief
Studies have investigated red clover's ability to alleviate menopausal hot flashes. Research has shown that red clover isoflavones may help reduce the frequency and severity of hot flashes, especially in women with more severe symptoms. However, results have been inconsistent across studies, and the benefits may be temporary, potentially fading after several months.
Supporting Bone Health
Postmenopausal women often experience a decline in bone mineral density due to decreased estrogen levels. The phytoestrogens in red clover may help prevent this bone loss. Some studies have found that red clover extracts can have a positive effect on bone health and can help improve bone mineral content.
Clover for Skin and Hair
Clover, especially red clover extract, has gained popularity in skincare and haircare for its rejuvenating properties.
- Skin Renewal: The isoflavonoids in red clover oil can help increase collagen production, improve elasticity, and reduce the appearance of fine lines and wrinkles. It may also help with skin irritations like eczema and dermatitis.
- Inflammation and Soothing: The anti-inflammatory properties of both red and white clover make them useful for soothing skin conditions, including acne, eczema, and burns.
- Hair Health: Red clover extract can support hair growth and strengthen hair follicles, potentially reducing hair fall. It is also known to help treat scalp conditions and irritation.
Cardiovascular and Antioxidant Properties
The flavonoids and isoflavones found in clover provide antioxidant benefits that help protect the cardiovascular system. Research on postmenopausal women has indicated that red clover supplementation may lead to a decrease in total and LDL ('bad') cholesterol, while increasing HDL ('good') cholesterol. The flavonoids also help improve the elasticity and strength of blood vessel walls, contributing to better heart health.
Culinary Uses of Clover
Beyond its medicinal applications, clover is a versatile and edible plant. All the aerial parts—the leaves, stems, and flowers—can be consumed.
- In Salads: Young leaves and flowers can be added raw to salads for a slightly sweet, grassy flavor.
- Herbal Tea: The flowers and leaves can be dried and brewed into a nutritious, caffeine-free tea. White clover tea, for example, is known for its mild flavor and ability to soothe colds and fevers.
- Other Dishes: The leaves can be cooked like spinach, and the dried flowers can be ground into a powder for use in baked goods.
Potential Risks and Side Effects
While generally considered safe for most people, some individuals should exercise caution or avoid clover completely. Potential side effects can include nausea, headaches, and skin irritation. Due to its phytoestrogenic and mild blood-thinning properties, it should be avoided by:
- Pregnant or breastfeeding women: There is insufficient safety data for these groups.
- Individuals with hormone-sensitive cancers: Those with a history of breast, ovarian, or uterine cancer should consult a doctor before use.
- People on blood thinners: Clover may interfere with blood-thinning medication.

| Feature | Red Clover (Trifolium pratense) | White Clover (Trifolium repens) |
|---|---|---|
| Primary Use | Women's health (menopause), cardiovascular health, skin/hair | Immune support, topical skin healing, digestive issues |
| Phytoestrogen Content | Significantly higher concentration of isoflavones | Lower levels of phytoestrogens |
| Active Compounds | Isoflavones (genistein, daidzein), coumarins | Flavonoids, isoflavones, polysaccharides, saponins |
| Traditional Remedy For | Menopause, arthritis, respiratory issues, skin disorders | Colds, fevers, coughs, joint pain, skin wounds, anxiety |
| Culinary Use | Dried flowers often used in teas | Leaves and flowers used in salads, teas, and cooking |

Conclusion
From ancient traditional medicine to modern applications in health supplements and cosmetics, clover has a surprisingly wide array of uses for human wellness. Its active compounds, particularly the isoflavones in red clover, offer potential benefits for menopausal women, supporting bone and cardiovascular health. White clover contributes to skin healing and provides antioxidant-rich nourishment. While research supports many of these applications, it is important to understand the distinctions between different clover species and to consult with a healthcare provider, especially when using extracts for medicinal purposes. As a gentle, edible herb, it can also be a nutritious and flavorful addition to the diet.
