There are important contraindications that apply to using Nettle. If any of the below contraindications apply to you, you should not use Nettle.

• Persons who are under 18 years old.
• Persons with a history of seizures or epilepsy.
• Persons who are pregnant or may be pregnant.
• Persons experiencing active suicidal thoughts.
• Persons with a pre-existing neurological or neuropsychiatric condition.
• Persons with a lesion, tumour or other defect in your skull, cranium or brain.
• Persons with an implant inside their skull, cochlear implant or implanted hearing aid.
• Persons with implanted medical devices, such as a cardiac pacemaker or neurostimulation devices, such as spinal cord stimulators, vagal nerve stimulators, auricular stimulators, or deep-brain stimulating electrodes.

If you are unsure about whether any contraindications apply to you, you must consult with your physician before continuing, especially if you are under the care of a physician for any conditions related to the central nervous system (e.g. neurology, psychiatry).

Yes! 47.1% of participants in our clinical trials self-identified as women of colour, 67.6% of them had wavy, curly or coily hair, and trial participants had a BMI range from 19 to 29.

Premenstrual dysphoric disorder (or PMDD) is a serious condition that - like much of women’s health - has been largely ignored by research, clinicians and solutions for too long. PMDD is a complex condition, with complex symptomatology, and women with PMDD do not necessarily have the same symptoms or experiences.

Nettle has been designed specifically with women in mind who have certain types of PMDD symptoms, especially low mood; and it may be worth exploring as an option alongside other treatment options. However, Nettle has not yet been tested on exclusively PMDD patient populations, and we’re currently investigating such benefits in a separate clinical trial.

During your luteal phase, fluctuations occur in certain brain regions which contribute to symptoms of PMS and menstrual pain such as low mood, anxiety, brain fog and cramps.
Your brain runs on electricity, and neurons communicate using electrical signals called action potentials. Nettle uses the natural language of neurons to rearrange and regenerate neural pathways - a process known as neuroplasticity. This is done by administering safe and small electrical pulses to brain regions where these fluctuations occur. We are able to target them via the placement of the electrodes on the headband, one targeting your dorsolateral prefrontal cortex (DLPFC) and the other targeting your insula via your motor cortex (M1).

This stimulation gets neurons firing in a way that is more consistent with follicular phase activity, empowering you to feel your best even during the premenstrual phase. The technology Nettle employs is well-known and validated from the fields of depression and chronic pain treatment.

Yes, extensively. We have run more than three years of tests on Nettle itself, and this builds on decades of research into the underlying neurotechnology and its mechanisms. These tests range across safety, efficacy, ergonomics, and more. The results of our WIND trial are available on our website and demonstrate significant improvement in low mood, pain and function after using Nettle for just 5 days, which is equivalent to one cycle. We are in the process of setting up and conducting more trials, including one with the NHS that will test the efficacy of Nettle amongst patients with endometriosis and other trials for PMDD, among other conditions.

Nettle is designed to help manage a variety of physical and psychological symptoms. Physical symptoms include menstrual pain and cramping, while psychological symptoms encompass low mood, irritability, anger management, mood instability, and brain fog. There is stronger evidence supporting Nettle's effectiveness for certain symptoms compared to others.

The technology behind Nettle has been rigorously tested in multiple clinical trials and continues to be assessed in ongoing studies to evaluate its effectiveness across various clinical endpoints.

Yes, Nettle has been rigorously tested for safety, and its underlying technology is supported by over 30 years of evidence demonstrating its safety for both short- and long-term use. However, as with all medical technologies, Nettle may not be suitable for everyone. The key contraindications for using Nettle are diagnoses and history of epilepsy and/or seizures, and any pre-existing neurological implants, which could interfere with Nettle’s mechanism of action.
