01 — CLINICAL TRIAL RESULTS

In direct clinical trials, Stinging Nettle was comparable to Spironolactone & Minoxidil, proven to reduce menopausal symptoms, and increase quality of life for women—all without side effects.

Women

Nettle was found comparable to Spironolactone in treating women suffering from hormonal imbalance and its symptoms: acne, periodic cycles, oily skin, and hair issues

Women

Nettle (Urtica) was proven in direct double-blind placebo trials to decrease menopausal symptoms in women

Women

Nettle was proven to balance key hormones (estrogen and progesterone) and support healthy ovulation, helping to regulate cycles and increase pregnancy success.

02 — MECHANISM STUDIES

Stinging Nettle was also clearly shown to contain compounds targeting:

  • Menopause: [1, 2, 3, 4]

  • PCOS: [1, 2, 3]

  • Alopecia: [1, 2, 3]

  • Cortisol / Stress: [1, 2]

Menopause

Nettle (Urtica) was proven in direct double-blind placebo trials to decrease menopausal symptoms in women

Menopause

Nettle acts as a natural shield to protect your ovaries from damage and keep your hormones balanced during the change into menopause.

Menopause

Lignans in Nettle have shown to clearly regulate SHBG, thereby increasing free estrogen when needed in women

Menopause

Nettle's lignans also help relieve menopausal symptoms while supporting breast, bone, and uterine health.

PCOS

Stinging Nettle (Nettle) was found comparable to Spironolactone in treating women suffering from PCOS and its symptoms: acne, periodic cycles, oily skin, and hair issues

Alopecia

Stinging Nettle’s β-sitosterol compounds were comparable in effectiveness to Minoxidil, increasing hair growth and improving hair condition.

Alopecia

In direct clinical trials, Nettle was found comparable to Spironolactone (the gold standard drug for women's alopecia hair loss), reducing excess androgens and its symptoms.

Alopecia

Compounds from Stinging Nettle (Urticadioica L) were found to increase hair length. Reducing inflammation at the scalp is necessary to ensure hair growth

03 — ADDITIONAL BENEFIT STUDIES

Stinging Nettle, through balancing hormones, has also shown in studies to:

  • Increase libido

  • Improve fertility

  • Support nutrient partitioning

  • Alleviate PCOS, and menopausal symptoms in women

  • Lower joint pain

  • Reduce fatigue

...along with other non-hormonal health benefits.

“We solved alopecia hair loss and hormonal imbalance by combining masterful herbalism with scientific precision. Like coffee beans for fatigue, or poppy flowers for pain, Stinging Nettle is nature’s lock-and-key solution for hair and hormonal conditions. Backed by rigorous scientific research, we guarantee real, lasting results—your hair grows, your hormones balance, or your money back. Simple.”

FAQs

When should I expect to see benefits?
Within 3 months, you should see significant hair growth in thinning areas. Hormonal benefits, reduced stress, often start within the first 1–3 full daily servings.

For best results, maintain a healthy diet and address nutrient gaps, particularly calcium. Optionally take a calcium + d3 supplement and/or multivitamin. Results may vary depending on individual health and consistent use.
Why do you offer a tonic and not a pill or powder?
Our research shows that a tonic is the only method for extracting the compounds targeting all root causes of alopecia hair loss and hormonal imbalance.

We’ve tested other viable methods, including pills, powders, and serums. Our discovery was that nothing comes close to the effectiveness of traditional hot water preparation. It's the exact reason why we use hot water to brew coffee on fresh beans rather than taking a coffee pill.
How exactly can one herb provide so many supportive functions?
Stinging Nettle is unique because its leaves, roots, and stems contain multiple bioactive compounds—lignans, sterols, polyphenols, flavonoids, polysaccharides, and coumarins—that naturally target the root causes of hair and hormonal health issues. These compounds evolved over millions of years to make Nettle perfectly suited for these problems—much like how coffee naturally boosts energy or poppies ease pain.

These powerful compounds aren’t found in everyday foods or typical supplements. We are the first to discover them, identify their benefits, and solve the alopecia hair loss & hormonal imbalance problem properly, and for good.
Why hasn’t anyone been able to discover this before you?
Most scientists missed this discovery due to a lack of nuance when interpreting scientific research. We combined deep study of the science with masterful herbalism, allowing us to discover novel insights, and spot where others went wrong.

For example, it’s often believed that DHT causes hair loss. However, we found that the real issue isn’t DHT itself, but how sensitive hair follicles are to DHT. Not everyone with high DHT loses hair: teenagers have high DHT but usually don’t lose hair, and women generally don’t lose hair due to DHT. Therefore, you do not have to remove DHT to stop hair loss; instead, you can repair the follicle's sensitivity to DHT, and in that case, prevent hair loss whilst still allowing hormones to be present.

By clarifying these misunderstandings, we made a breakthrough that unlocks Stinging Nettle’s true potential for hair and hormonal health. For a detailed explanation, visit our blog.
I want even more evidence, where can I find it?
For detailed evidence, check out our in-depth blog post, where we explain how we developed our solution for hair loss and hormonal imbalance. It cites over 150 scientific sources and walks you through the research and our discovery process.

While no direct clinical trials on our product exist yet, we combine extensive scientific literature with real-world testing and logical analysis. This comprehensive approach highlights the powerful benefits of Stinging Nettle: an elegant, natural solution many have overlooked.
