Adrenal glands are stress supervisors. They release anti-stress hormone Cortisol which suppresses the release of the body’s “feel good” hormone Serotonin, amplifying the anxiety and also augmenting depression, as well as Melatonin, the hormone related to sleep. Adrenal glands are responsible for the “fright, fight & flight” response of our bodies. It is these glands which feel the maximum punch of nervous tension. Adrenal fatigue is a collection of symptoms such as body ache, fatigue (not relieved by sleep), nervousness, sleeplessness and digestive problems. Nux vomica (homeopathic medicine) restores this miserably imbalanced state of affairs.
