Nettle, is a Class-IIa, CE-marked, drug-free, hormone-free, Bluetooth-controlled wearable transcranial direct current stimulation (tDCS) device developed by women at Samphire Neuroscience, and is tailored to women’s needs. Nettle provides non-invasive stimulation to both the motor cortex (to alleviate physical pain) and the prefrontal cortex (to improve symptoms of mood disorders). Use of Nettle during the final two weeks of the menstrual cycle has been shown to relieve pain and low mood associated with dysmenorrhea (painful menstrual cramps), premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD).
