If you’re battling breakouts, bloating, UTIs, or PCOS symptoms, you’ve probably seen herbs like spearmint, hibiscus and cranberry pop up again and again. Here’s what the research actually says, why it matters for skin and women’s health, and how Carmién blends may be help you in your journey.
A small randomised controlled trial found that drinking spearmint tea twice daily for 30 days lowered free and total testosterone compared with a placebo herbal tea (Grant, 2010). Those hormone shifts are relevant because androgen spikes can drive oiliness and some forms of acne; the same trial reported better self-rated skin outcomes even though clinical hair scores didn’t change over a month, likely because skin and hair cycles need longer (Grant, 2010). A peer-reviewed article reaches a similar conclusion: spearmint appears to have anti-androgen activity, with early signals for androgen-linked concerns like acne and hirsutism, but bigger, longer trials are still needed (Grant and Ramasamy, 2012).
What to do with that? If your breakouts ebb and flow with your cycle, having spearmint daily is a low-risk way to test if calmer androgens make your skin calm down too. Carmién Refresh combines rooibos, green honeybush and spearmint for a crisp, anytime cup.
If you want gut support alongside spearmint, Carmién Gut adds green rooibos, fennel, chicory root and Bacillus coagulans with spearmint, which makes it a practical choice when bloating and skin flare-ups travel together (Carmién Tea, 2024).
Hibiscus calyces are rich in polyphenols and anthocyanins with antioxidant and anti-inflammatory actions, which are relevant to the metabolic and inflammatory features of PCOS (Indumathi and Abi Beaulah, 2024). Emerging evidence includes a small clinical report of symptom improvements after hibiscus tea supplementation and broader discussions of hibiscus’ metabolic effects in PCOS-related literature (Indumathi and Abi Beaulah, 2024).
Consumer summaries echo potential benefits such as blood pressure and lipid support, while reminding readers to watch medications that interact with hibiscus (PharmEasy, n.d.; Milvago, 2024). The bottom line: hibiscus isn’t a PCOS treatment, but it’s a reasonable, food-first way to support cardiometabolic health as part of diet, movement and medical care, which may help relieve symptoms (Indumathi and Abi Beaulah, 2024; PharmEasy, n.d.; Milvago, 2024).
Drink Carmién Cranberry Hibiscus Cold Brew regularly, track your cycle and energy, and keep your healthcare provider in the loop if you’re on antihypertensives or other meds.
Cranberry’s best-supported role is prevention of recurrent UTIs in specific groups. A 2023 Cochrane review of 50 trials (8,857 participants) concluded that cranberry products reduce symptomatic, culture-confirmed UTIs in women with recurrent UTIs, in children and in people with procedure-related risk, while showing little or no benefit in pregnancy, the elderly in care and some neurogenic bladder groups (Williams et al., 2023). A 2021 meta-analysis also found a significant risk reduction, with the mechanism linked to A-type proanthocyanidins that make it harder for E. coli to stick to the urinary tract (Xia et al., 2021). The FDA allows a qualified health claim for certain cranberry juices and supplements, but stresses the evidence is limited and inconsistent, so wording must reflect that (FDA, 2020).
Beyond UTIs, mainstream nutrition sources note cranberry’s vitamin C and polyphenols for general wellness and heart health markers, plus its long-standing use for urinary comfort; these are helpful context points rather than treatment claims (BBC Good Food, n.d.; Health.com, 2022; Lyndhurst Gyn, n.d.; NDTV, 2025; Healthline, 2024).
