Injecting medication at the Feng Chi acupuncture point may deliver substances to the brain through fluid spaces surrounding blood vessels.
Healthy mice received Evans Blue dye injections at the Feng Chi acupuncture point, after which researchers examined dye movement through the head and brain, focusing on pathways associated with the trigeminal structures, cribriform plate, and spaces surrounding blood vessels.
The dye spread from the injection site into the mouse head and brain through these fluid pathways, suggesting that pharmacopuncture at the Feng Chi point could provide a route for delivering drugs to the brain.
