Why not just use coconut oil? Get it in the pharmacy section (not cooking) it needs to be organic virgin. Its anti-fungal, anti-bac, etc. so it will do yeast, ring worm, pink eye, diaper rash, etc. We use it as regular lotion as well and whenever my kids have cuts I put it on it instead of neosporian.
Coconut oil has TONS of uses, google them. I can't count all the things I've used it on. DH used tree tea oil for ringworm, its also a great and safe bug repellent. The only thing in my kids medicine cabinet are coconut oil, tree tea oil and arnica for bumps and bruises.
