You might be asking yourself how does SGB work, we can help. Have you heard of a nerve block or received a numbing injection before, like at the dentist? DSR SGB is an injection that "numbs" your sympathetic nervous system.
What does that do? It allows your body to decrease the flow of norepinephrine (adrenalin) to your amygdala (fear center). Norepinephrine is responsible for "stressful emotions" like anger and fear and your amygdala ow we act in a crisis. When your amygdala receives stressful emotions, it believes you're threatened and responds as such.
It also "prunes" any extra nerve fibers responsible for transmitting this hormone. After the numbing anesthetic wears off, your the amount of transmitting nerve fibers should be reduced, similar to blowing off flowers of a dandelion.
