Homeopathy plays vital role in curing an infectious diseases. Homeopathic medicines can kill bacteria out of human body. This fact has been clinically proven. When consumed in an infectious disease the medicines acts in two ways. One it stimulates the life force (Vital Force) that governs the body through nerve endings which in its turn attack the bacteria, viruses to cure the illness. Second the medicine itself attacks the bacteria and viruses to kill them. Cure with the first action in Homoeopathy is termed as cure with secondary action, which is long lasting and makes the immune system stronger. Cure in the second way is termed as cure with primary action, which is short term and does not make the immune system stronger. Homoeopaths always try to cure a patient with secondary action, unless otherwise contraindicated.Viral infections such as common cold, influenza, measles, Chickenpox, mumps, viral hepatitis (jaundice), viral meningitis etc. are very well treated with homoeopathy. Allopathic system has no curative treatment for viral diseases.
