The adrenal gland performs a unique role in the body and has unique nutritional requirements. To effectively support blood sugar levels, coordinate the immune system response and control energy levels, it must release the right amount of adrenaline, cortisol and DHEA, three of the adrenal hormones. Some herbs can help maintain this balance.
Licorice Root
Often used in confections for its sweet flavor, licorice provides useful properties for the adrenal glands. Its root contains a compound called glycyrrhetinic acid, which demonstrates a reliable effect of boosting cortisol levels. Cortisol, a steroid hormone released from the adrenal cortex, reduces inflammation and maintains blood sugar levels between meals. Licorice root achieves this effect by inhibiting the breakdown of the hormone at the liver, which increases levels of cortisol in circulation.
Siberian Ginseng
Siberian ginseng is one of the numerous compounds dubbed an adaptogen. Adaptogens consist of herbs that have demonstrated the ability to normalize the functions of the human body, simultaneously lowering the excessive release of some hormones while increasing the production of those that remain low. Siberian ginseng, or eleuthero senticoccus, appears to do the same with cortisol levels. Researchers from the University of Maryland Medical Center report that Siberian ginseng has shown promise in treating a variety of conditions. Although results have been mixed, the herb may improve physical and mental performance as well as resistance to infection.
Valerian Root
In times of acute stress, signals from the central nervous system stimulate the secretion of adrenaline from the adrenal medulla. Adrenaline stimulates both muscle and fat cells to release the sugar and fatty acids they contain, increasing availability in the bloodstream. Adrenaline also activates part of the brain known as the amygdala. Dr Robert Kapolsky, author of the best-selling book on stress "Why Zebras Don't Get Ulcers," explains that the amygdala makes individuals anxious and alert and also stimulates the release of more adrenaline, which fuels a vicious cycle. Valerian root stops this cycle by inhibiting further signals from the central nervous system to the adrenal medulla. Herbalists recommend it for relief of anxiety and insomnia.
