Meet Nettle™

Women experience their menstrual symptoms through their brain... so we created a clinical-grade headband that delivers PMS and period pain relief.

What is Nettle™?

The only medically-certified, hormone-free and drug-free treatment for PMS and menstrual pain.

By mimicking the brain's activity during the follicular phase, Nettle™ helps you regain clarity, comfort, and control throughout your cycle with just 20 minutes a day in the second half of your cycle.

Nettle™ does this by sending gentle, targeted pulses to the two regions of the brain responsible for controlling your mood and pain symptoms associated with your period and nudging them to reset.

You can try Nettle™ risk-free for 3 cycles with our 90-day returns policy.

Guiding your Nettle™ setup

Place the grey electrode covers into the electrode cases within the band and soak the electrode covers in saline solution until they feel spongey and wet. It may take more liquid than you think depending on the thickness of your hair.

Place Nettle™ comfortably on your head and press it onto your scalp. Your hair and shoulders near the headband will get a little wet - we recommend styling your hair post session.

Connect with the Samphire App and start your 20-minute session. You're free to do other things in the meantime, just keep your headband in place for good contact.

What's included:

  • Nettle™ at-home brain stimulation headband
  • All supporting accessories
  • A year of access to the Samphire app
  • Free express shipping
  • 90-day money back guarantee
  • 1 year warranty
  • Just 20 minutes a day in your luteal phase

Our users have felt the difference

I’ve also tried other treatments including antidepressants and TMS but none have been as effective.

I’ve been using the Nettle headband by Samphire Neuroscience almost since it’s launch and it’s made a remarkable difference to my depression and anxiety that I experience as a result of PMDD. I have a long cycle and experience 2 weeks of PMDD that used to feel completely unmanageable, when I use Nettle from ovulation onwards I experience a significant reduction in symptoms. I’ve also tried other treatments including antidepressants and TMS but none have been as effective in alleviating some of my symptoms.

It is truly a life-changing creation (if you are a woman suffering from PMS of course).

I have been using Nettle for almost a year and it is truly a life-changing creation (if you are a woman suffering from PMS of course). It has not only helped me to become more aware and be more in tune with my body, but made me more conscious about my bodily sensitivity. It's fascinating how our bodies work and I hate to think I used to heavily fill it with painkillers every month.

For the first time in years, I feel like I’ve regained a sense of control over my life.

I am absolutely amazed by Nettle! After just seven sessions, I’ve noticed a remarkable positive effect, especially emotionally. Normally, I struggle with depression, self-doubt, and a significant lack of energy right before my period—but this time, none of that! Instead, I feel empowered, confident, and full of energy. Even my period itself was less painful; for the first time, I didn’t need painkillers (and I usually rely on 2-3 ibuprofen). The pain was manageable, and that alone is a huge relief.

Truly revolutionary product

The Nettle from Samphire Neuroscience is absolutely a game-changing breakthrough in the field of female health. I have suffered from debilitating PMDD for the past 3 years and have noticed a significant improvement in my mood since using the Nettle. No other treatments have delivered on their promises like the Nettle has, and no other treatments are targeting the root of the problem like the Nettle does. The app experience is seamless. The customer service and support is INCREDIBLE.

Works even better during the 2nd month

If you have a Nettle device from Samphire neuroscience and did not receive significant relief during your first cycle, I highly recommend giving it another try in the second cycle. The instructions note that it can take up to three cycles to see significant reduction in symptoms, and that is the case for me. I found a decent amount of relief during the first month I tried this device, and am seeing an incredible improvement in the second month. There is still some head tingling and discomfort, but I now look forward to the feeling, knowing that it will help me feel clear-headed, calm, and in minimal pain even if it’s “that time of the month.” I started using it a few days before PMDD symptoms usually set in, and this has worked incredibly well so far. To my fellow PMDD sufferers: hope has arrived.

The data speaks for itself

Why thousands of women are choosing neurotechnology instead of the usual treatments

Non-invasive, drug- and hormone-free

Nettle™ offers an effective and clinically-validated treatment for menstrual symptoms without relying on painkillers, SSRIs or hormonal contraception.

Nettle's™ gentle, low-current pulses mimic the brain’s natural energy, helping your brain rebuild healthy pathways without side effects.

Outperforms traditional treatments

Nettle™ has proven to be a safe alternative that outperforms painkillers (NSAIDs), hormonal contraceptives or "the pill" (COCs), and anti-depressants in managing pain, mood, and overall functionality while reducing side effects.

The traditional treatments listed above only work for 18-53% of women with severe period-related symptoms.

Review the independent research and industry meta-reviews (here and here)

Zero severe side effects

Not a single severe side effect has been reported in over 30 years of research and use, due to the non-invasive nature of Nettle's™ technology (tDCS).

We have never had women discontinue our trials due to side effects, and are uncompromising that women deserve effective solutions that don't put their safety at risk.

Mild side effects include itchiness & tingling near the headband, which passes with time and, in rare cases (<1%), transient headaches or nausea (resolving within 30 minutes).
