| How it works | Phyto-SERMs are plant-derived compounds that bind to estrogen receptors in target tissues such as the brain and bones, but not in uterine or breast tissue. This tissue-selective activity may relieve hot flashes and night sweats without stimulating breast or uterine tissues. | A clinician injects local anesthetic into the stellate ganglion, a nerve bundle in the neck that is part of the sympathetic nervous system. This may interrupt the temperature-regulation signals that trigger hot flashes. |
