Our adrenal glands produce the hormone adrenaline, or epinephrine, which increases the rate of our metabolism when we are under stress. This chemical reaction was an important biological adaptation in situations where heightened awareness could save us in life threatening situations, such as being stalked by predators. But today, much of our stress comes from workplace situations that are hardly life threatening. The daily nature of stress in modern life takes its toll on our adrenals, causing a condition called "adrenal fatigue." Fortunately, there are a range of medicinal herbs that can help to revive fatigued adrenals and restore adrenal function.
