Antibiotic treatments, vaccinations and parasite treatments are sometimes important and unavoidable. However, they often have undesirable side effects that affect the organism. The aim of antibiotic treatment is to get rid of harmful bacteria. For this purpose, the antibiotic has the property of killing bacteria. Unfortunately, the antibiotic cannot distinguish between different types of bacteria, killing both harmful and useful bacteria. Approx. 70 % of the immune cells are located in the intestine. If the intestinal flora is affected, the immune system does no longer function properly. Some useful intestinal bacteria cannot regenerate without help.This is often underestimated. Therefore, it is important to stabilize the intestinal flora after antibiotic treatment, vaccinations or after parasite treatments.
