Will tea tree oil help clear up toenail fungus?

yes & there are many home remedies available with varying degrees of effectiveness or you can opt for a natural solution from certain nail fungus treatment websites

I ordered just the topical treatment from rxorganica.com It's been 3 weeks now and I can start to see the pure white healthy nails growing in at the base! It seems to be working so far.

I used that and neem oil, it works well for me.

Yes, tea tree oil really helps in the treatment of nail fungus. In fact, the efficacy of tea tree oil the same as with prescription drugs. It has been proven through randomized clinical trials.
