Anxiety is the feeling of heightened arousal or worry that occurs without an obvious external threat or in response to a disproportionately trivial or benign stimulus. It consists of both an emotional and a physical imbalance, and tends to be provoked by overwork, stress, fear, or insecurity. It is sometimes accompanied by an increased pulse rate, clammy skin, irregular sleep patterns, and appetite disturbance. Stress, anxiety and overstimulation can occasionally put severe strain on the body’s autonomic nervous system. Natural remedies activate the body’s own regulatory mechanism and help to stabilise the functions.
