Based on the premise that the stellate ganglion may regulate the body's "fight or flight" response and the overactive sympathetic nervous system, which is frequently linked to PTSD, a stellate ganglion block is one method of treating post-traumatic stress disorder (PTSD). It is thought that by using an anesthetic to inhibit the stellate ganglion, the treatment may help reset or modify the body's stress response.
