Empower your patients with brain-based care for their menstrual health.
Samphire Neuroscience combines noninvasive neurostimulation with intelligent cycle tracking - giving your patients science-backed support for pain, mood, and focus.
Samphire’s flagship solution, Nettle™, provides relief from menstrual pain and mood symptoms.
Non-invasive brain stimulation
Nettle delivers transcranial direct current stimulation (tDCS) through a compact, wearable device - using low-intensity electrical currents to modulate brain activity related to pain and mood. Treatment is self-administered, pain-free, and guided by Samphire’s companion app.
Minimal side effects and no drug-on-drug interactions
Nettle™ works through the brain, not the bloodstream, so it does not interact with hormonal treatments or other medications. Side effects are minimal, with most users reporting only mild scalp sensations during use.
Easily integrated into care plans
Nettle™ can be tailored to different symptom patterns and diagnoses. Patients can receive a personalized protocol and export usage summaries or symptom logs as needed.
