Depression is a mood disorder that causes a persistent feeling of sadness and loss of interest. Also called major depressive disorder or clinical depression, it affects how you feel, think and behave and can lead to a variety of emotional and physical problems. You may have trouble doing normal day-to-day activities, and sometimes you may feel as if life isn't worth living. Depression results from a complex interaction of social, psychological, and biological factors. People who have gone through adverse life events (unemployment, bereavement, traumatic events) are more likely to develop depression. A good homeopathic treatment can completely heal various symptoms of depression. Some of the homeopathic medicines for depression Arsenicum album, Aurum metallicum, Calcarea carbonica, etc. have shown very encouraging outcomes.
