People claim only the treatment with the medicine will have the side effect. But it is fallacy. To understand this we need to understand something about the germs.
As some alternative system proposed, the germs are attracted towards their food(waste for human) in our body. By cleaning the morbid matter, the germs will go away. These are all go well if we able to remove the morbid matter from our body immediately. But the fact is it will take time to remove the morbid matter. During the period, there is a possibility of germs to disturb our regular activity. This can be illustrated with the following example.
Assume the mosquito is the germ. The morbid matter is the small dirty ponds around our area. The reason for arrival of mosquito is due to the dirty environment. After arrival, it will disturb all the living organism by biting the living organism. We can eliminate the mosquito by two methods. 1) killing the mosquito 2) removing the morbid matter around the area. The first method is followed by the Allopathic medical system. The second method is followed by many alternative medical systems.
It will take time to remove the morbid matter. Due to the time delay in the removal of morbid matter, we face the disturbance from the germs. This we can say as the side effect of the medicine less treatment.
