What microbes are in yogurt?

It is used to ferment the milk

The growth of the bacteria in the milk is what makes the milk become yogurt. If they are not alive, you won't be able to make yogurt. If the milk is too hot when the culture is added, the bacteria will die and the process will fail. If the milk is kept too cold, the bacteria won't grow and the process will fail.

Yogurt has a lot of good bacteria in it, which would replace the good bacteria you may be lacking. It balances your body's pH and keeps the intestinal tract on track. It will also help for a woman if she has a yeast infection or her pH is off. You can actually use the yogurt as a douche for a few days to replace good bacteria in the vagina and help treat the yeast infection. It can replace and help more than medications can. Just make sure the yogurt has the live active cultures and is plain (not flavored with fruits like strawberry, etc.)
