The E9 is always in my bag, (as well as beside my bed!). From placing it on the sternum (at the girth), for either pain relief or to ground the horse, to stimulation acupuncture points to relax the whole hind quarters. Another favorite application is stimulating the stomach alarm point to increase gut motility. hanging an E9 in a horses stall to calm and help settle them, or to help them deal with transition. So many safe and wonderful uses!
