This formula is for relieving the symptoms of being in a higher altitude than you are accustomed to. These herbs help put more oxygen in your system to ease the distress of a higher altitude and have a calming effect. Rhodiola has been shown to help combat fatigue, stress, and the harmful effects of oxygen deprivation. Ginkgo increases blood flow to the brain and increases blood circulation through vasodilation. This increase in the oxygen supply to brain cells is an important factor as the brain is our body’s most sensitive organ to oxygen deprivation. Licorice and Valerian help with any resulting stress.
