A new brain-stimulating device developed by Samphire Neuroscience is now available across the UK and Europe, offering a fresh approach to managing menstruation-related symptoms. Named Nettle, the wearable has become the first CE-certified brain device created specifically to ease both the mental and physical discomfort often linked to menstruation.
Nettle operates using transcranial direct current stimulation (tDCS), a non-invasive technique that targets brain regions associated with mood regulation and pain relief. The device is designed to be worn for 20 minutes per day, ideally during the five days leading up to menstruation.
Demand has already outpaced supply, with the product selling out twice during its pre-launch phase. According to Samphire, the device has drawn significant interest from those living with conditions such as premenstrual dysphoric disorder (PMDD), endometriosis, polycystic ovarian syndrome (PCOS), and chronic pelvic pain.
As part of its CE certification, Samphire presented evidence showing that users experienced mood improvement, pain reduction, and better daily functioning within just one month of use.
Feedback from early users has been largely positive. Independent reviewers on Trustpilot have highlighted symptom relief without reported side effects. Several users shared that the device helped ease severe anxiety and depressive episodes during the luteal phase, while also being simple to incorporate into everyday routines.
Founded in 2021, Samphire Neuroscience focuses on neuromodulation solutions for women’s health, combining scientific research with input from clinicians and patients. The company estimates that over 190 million individuals globally suffer from chronic menstrual conditions, many of whom struggle to find effective treatment.
Nettle, which is hormone-free and does not interfere with other medications, is now available via Samphire’s official website with a 90-day return policy. Distribution through selected partner clinics and NHS-linked pilot schemes is also planned.
