regarding the question: "Do you know if there are any vitamins or herbal supplements that can help reduce or regulate the emotional adrenalin? Thanks, John" I know that adrenalin causing situations also dump sugar into the blood stream as a part of the fight or flight response. As the adrenalin recedes, we need to balance out the blood sugar. Post alarming situation, I like to eat, take Rescue Remedy (a Bach Flower Essence) and use the large muscles in the body to allow the body to express itself. A fear dance, a walk around the block and vocalizing all help. Long term stress induced adrenalin dumping could be helped by supporting the 'Kidney Qi' per Chinese Medicine and by taking Chromium supplements and flowers essences like Rescue Remedy or homeopathics like Ignacia.
