Uh, if you have the typical fungal infection in that area, ringworm, you use a cream. It's much less stressful on your system with fewer systemic side effects to use it that way. Taking it orally is much stronger, but has a lot of side effects, and this way it goes directly where your problem is. Make sure you use it as long as recommended, and don't be surprised if it comes back, as this treatment often doesn't get all the eggs. Good luck with it.
