Pueraria Mirifica, also known as Kwao Krua Kao, is a plant native to Thailand and Myanmar containing phytoestrogens, primarily used for its potential to alleviate menopausal symptoms. It is available as a dietary supplement and is often marketed for its benefits on skin health, bone health, and vaginal dryness. While preliminary research suggests potential benefits, more robust studies are needed. Common side effects include irregular uterine bleeding, breast tenderness, and gastrointestinal issues.

Inside BodyPotential Benefits
Enhances bone density, strength, and integrity by supporting bone formation, calcium absorption, and reducing age-related bone loss. Improves overall skeletal health and function, ultimately reducing the risk of fractures.
This benefit aims to improve overall skin health and appearance through increased hydration, reduced inflammation, improved elasticity, and protection from environmental damage. Healthy skin exhibits a smooth texture, even tone, and strong barrier function.
*Lactobacillus* bacteria help maintain a healthy vaginal flora by inhibiting pathogenic organisms, preventing and managing vaginal infections like bacterial vaginosis and yeast infections. Supplementation can occur orally or vaginally.
Maca may reduce menopausal symptoms like hot flashes and sleep disturbances. More research is needed to confirm these benefits and understand the mechanism.
Possible Side Effects
Headaches are a common side effect characterized by pain in the head, ranging from mild to severe, potentially accompanied by nausea and sensitivity to light/sound. They can be triggered by various factors, including dehydration, stress, or medication.
Gastrointestinal issues include nausea, diarrhea, abdominal discomfort, and vomiting, potentially stemming from altered gut motility, microbiota changes, or irritation. While often mild, persistent symptoms necessitate evaluation, and contributing factors like pre-existing conditions should be considered.
Pueraria Mirifica's estrogenic properties can lead to irregular or prolonged uterine bleeding. This is due to disruption of the normal menstrual cycle.
Breast tenderness is pain or soreness in the breasts, often linked to hormonal changes, particularly estrogen. While usually not serious, it can cause discomfort.
