Sure. It's good for canker sores, athlete's foot, indigestion... My toddler stepson has a host of skin problems and very frequently has
fungal skin infections (like ringworm, thrush, jock itch, and others.)
Basically fungus and bacteria are enemies. If you have a fungal problem of any kind, increasing the "good" bacteria in your body will help fight it. I've found Lactinex to be the most effective for both my husband and my stepson (mixed in orange juice for the toddler, because it's a really foul-tasting powder.) It clears up canker sores within a day, and large outbreaks of ringworm in three or four, whereas the anti-fungal creams like Tinactin would take weeks and weeks.
