In fact Antibiotics , especially the artificially produced ones, seriously damage the immunology system, so much, that it can weaken in fighting some bacterias as much as 100 thousand times. This is why it is so easy to be infected again after taking Antibiotics . When the immunology system is harmed so deeply, yeast, bacteria and many other parasites have much easier way to develop in the organism.
Use the Antibiotics only when there is no other way and the body is almost dieing.
More then half of the antibiotics prescriptions don't heal but only damage the body.
99% of the antibiotics prescriptions are not necessary, because the immunology system is strong enough to heal the body if the person helps a little by (for example) modifying the diet, doing some energizing exercises.
