Why do we suffer from any disease?           Concept     We suffer from any disease only when our inherent immune system is affected or lowered. It is just like the terrorist attacking our country since the country is not strong. If our body is strong no organism can attack us and we don't suffer. Many times one can eat anything (or roadside food) and not have a problem since body can take care of itself. Hence prevention means strengthening the body. In homeopathy this can be done by,           Specific Preventive Medicines These are useful in epidemics like Chicken pox, African fever, Yellow fever and Conjunctivitis. These are acute diseases and prevention should be taken. Medicines like Variolinum, Terebinth, Pulsatilla are good preventive medicines.           Constitutional Medicines People who are already taking homeopathic medicines / treatment are given their core medicines or constitutional medicines which work as effective preventive medicines. They help to keep the body in top form and prevent illness.           Anti-Miasmatic Medicine These act like broad spectrum anti-biotics and help to prevent any infection ill diagnosed or ill understood. Tuberculinum is an excellent medicine.           Prevention In Chronic Diseases Prevention also means to help retard the process of disease, the pace or speed of disease, prevent its complications, prevent early deterioration. All this would help a better quality of life.   For example in cervical spondylitis the changes are degenerative so medicines can not change what is already happened. But by homeopathy we can reduce the pain, see that patient does not need to wear the collar, degenerative process occurs slowly so that patient can do work, travel, maintain good life-style even through advanced age. It is always advisable to take preventive consultation by a qualified homeopathy.
