Do a bit of research on Acidophilus - (Lactobacillus acidophilus), a bacterium found in the mouth, intestine and vagina, is used as a probiotic. Probiotics are good bacteria that are either the same as or very similar to the bacteria that are already in your body.
I discovered this probiotic back in the 80s when my g/f explained her annual cycle of yeast infections, lip sores etc. annually, treated with antibiotics for over 15 years . . .
Guess what - when I convinced her to try the PRObiotic, everything disappeared - no cold sores, no yeast infections, and never had to take antibiotics again (for the sores/infection)
I found they settle an upset stomach, ya know, when ya chow down on that food that ur mouth loves, but ur tummy don't.
I even gave them to a girlfriend's kids who had an upset stomach, or sore throat - cured their discomfort within minutes as I asked them to just open the capsule, and pour the powder right into their throat. It worked! And one of the kids gave it the nickname "white chocolate".
35 years later, I'm still "doing" Acidophilus, especially when I eat anything spicy.
Something to ponder.
