tea tree oil in liver cleanse?

Tea tree oil tincture in major cleanse??

I came across this:

Tea tree shampoo creates an entire exodus of soil worms (see videoclip below):

Obviously worms really really don't like tea tree oil! Tea tree oil can be quite strong and I'm not sure if it can be used orally. I've seen it successfully used externally on street dogs for scabies in poor countries.

Has anyone tried tee tree oil during worm and parasite cleanse? If yes, what would the dosage be?
