Cold is associated with Runny nose, sore throat, cough, congestion and sneezing. Generally, an adult gets 2-3 episodes of cold in a year but if the frequency increases beyond this, it may be due to various reasons like stress, lack of sleep, inappropriate eating habits, inappropriate hygiene. Homeopathic medicines work by optimizing the overactive immune system. Homeopathic medicines provide a stimulus to the body like that of the trigger or allergen leading to the gradual desensitization of the immune system, thereby reducing the tendency to get cold.
