where on earth can you get quassia yelp?

I've never heard of Quassia but I do know this: Wash hackle with Peppermint shampoo, coat the curls with grease (we used Olive), wear a shower cap overnight. In the morning bathe with the peppermint shampoo. Do this three night in a row, and they will be gone. Don't forget to hose all linens, clothing, and the other things you hold to do with lice.

if you scrounging how to use it purely as a herb, I don't know & am not sure if it's work.
But there;s a tea-tree & quassia manager lice shampoo available (from Victria health):
