I heard of Palo Brazil wood a few years ago from an Cuban/Ecuadorian Dr. I am a paraplegic with a suprapubic Cath. I used to suffer from “innumerable” kidney stones. There were too many to count. I also suffer from chronic UTI’s. I recently found Evergreen’s brand of Palo Brazil. Let me tell you it is absolutely amazing. I slow boil about 4-6 chips of wood in a pot with large black tea bags. I like to drink black tea. What’s great about the Evergreen brand is even though I mix it with the black tea I can still see the deep purple hue of the Brazil wood. As you can see from the picture I use older ships several times over again. Just adding a few new ones each time. Evergreens brand is so amazing I just bought 2 more pounds and on my way to get some more. Very much recommend Evergreens Palo Brazil wood.
