Pueraria mirifica, a traditional Thai herb rich in phytoestrogens such as miroestrol and deoxymiroestrol, is often associated with menopause relief and hormone balance in women. Yet, beyond its more publicised uses, research indicates that this plant may offer additional, lesser-known health benefits, ranging from bone protection to lipid profile improvement, antioxidant and neuroprotective effects, and improvedskin health. This article delves into these emerging areas, exploring how Pueraria mirifica might support overall health in ways not commonly discussed. Let’s explore Pueraria Mirifica and hidden benefits beyond its benefits to hormone balance.
What Makes Pueraria mirifica Unique?
Pueraria mirifica contains a high concentration of potent phytoestrogens and isoflavonoids (Cherdshewasart et al., 2010). These compounds can bind to estrogen receptors (ERα/ERβ) and modulate hormonal, metabolic and cellular pathways (Cherdshewasart et al., 2010; Laupattarakasem et al., 2007). Because of this molecular activity, the herb is being studied not just for menopausal symptoms, but for wider systemic health effects.
Lesser-Known Benefits of Pueraria mirifica
1. Bone Health Protection
Although often viewed as a female-oriented benefit, one animal study found that Pueraria mirifica prevented bone loss in orchidectomised (testicle-removed) male rats—with positive effects on bone mineral density in both trabecular and cortical bone (Soodvilai et al., 2006).
Soodvilai, P., et al. (2006). Pueraria mirifica, a phytoestrogen-rich herb, prevents bone loss in orchidectomized rats. Journal of Bone and Mineral Metabolism, 24(6), 555-560.
(This suggests potential benefit for age-related bone fragility, not only in women.)
2. Improved Lipid and Cardiovascular Profile
In a small human trial, postmenopausal women receiving Pueraria mirifica showed increased HDL (“good”) cholesterol by ~34% and decreased LDL (“bad”) cholesterol by ~17% over two months (Laupattarakasem et al., 2009).
Laupattarakasem, P., Prachaney, P., Navasumrit, P., et al. (2009). Pueraria mirifica phytoestrogens improve dyslipidemia in postmenopausal women probably by activating estrogen receptor subtypes. Clinical Interventions in Aging, 4, 543-552.
While this trial was female-focused, the mechanism points to systemic lipid metabolism modulation which may apply more widely.
3. Neuroprotective & Cognitive Support
Research in rats with induced cognitive impairment found that Pueraria mirifica extract improved memory and reduced markers of neuronal decline (Anukulthanakorn et al., 2016).
Anukulthanakorn, K., Parhar, I. S., Jaroenporn, S., Kitahashi, T., Watanabe, G., & Malaivijitnond, S. (2016). Neurotherapeutic effects of Pueraria mirifica extract in early- and late-stage cognitive impaired rats. Phytotherapy Research. doi:10.1002/ptr.5595
This suggests lesser-known potential for supporting brain health, especially in aging or stress-related cognitive decline.
4. Skin & Beauty Benefits
Phytoestrogens from Pueraria mirifica are being used in skincare formulas to support collagen production, improve skin elasticity, reduce fine lines and pigmentation (Clinikally blog, 2024).

These effects offer aesthetic and dermal health benefits that go beyond hormone replacement.
5. Antioxidant and Anti-proliferative Activities
In cell-culture studies, Pueraria mirifica extracts inhibited proliferation of certain cancer cell lines (MCF-7 breast cancer cells) at high concentrations and showed antioxidant effects (Udomruk et al., 2004).
Udomruk, S., et al. (2004). The differential anti-proliferation effect of white (Pueraria mirifica) … on the growth of MCF-7 cells. Fitoterapia, 75(2), 125-132.
This suggests potential in supporting oxidative-stress defence, though human data is limited.
Safety, Use & Considerations
While many of these benefits are promising, it’s important to note that research is still preliminary. Some human studies are small or female-only, and product quality varies. Pueraria mirifica appears to be well tolerated in short-term trials (Kuning & Foster, 2012) but long-term safety in all populations remains under-investigated.

It is always advisable to consult with a healthcare provider before use—especially for those with hormone-sensitive conditions, using medications, or pregnant/breastfeeding.
Pueraria mirifica is more than a herb for menopausal relief—it’s a multifaceted botanical with emerging benefits in bone health, cardiovascular support, cognitive maintenance, skin health and antioxidant protection. While more research is needed, these lesser-known benefits make it an intriguing addition to wellness routines under appropriate guidance.
