I might step on a few toes here, but I am really starting to dislike the over-saturation of antibiotics on the market. A lot of this stems from misinformation about antibiotics. Case in point, some people will take them for a common cold when a common cold is caused by a virus, not bacteria. Additionally, heavy or frequent use of antibiotics can have negative effects on your body.
Antibiotics target ALL bacteria, including the good bacteria in your body. This means that the good bacteria found in your stomach gets reduced and causes diet and digestion problems as a result. So how do you get good bacteria back? Well, there are of course probiotic yogurts and such, but this lady has a list of yummy and interesting sources for your probiotic needs.
