Pau d' Arco

I've been reading 'Timeless Secrets' by Andreas, and the benefits of Pau d' Arco are tremendous:

Cancer, AIDS, arteriosclerosis, bronchitis, cystitis, diabetes, gastritis, hernias, infectious diseases, leukemia, liver ailments, psoriasis, parkinson's disease, skin problems, varicose veins, colds, flu, polyps, ability to detoxify the body, particularly the liver, kidneys, and intestinal tract. Just to name a few.

Does anyone know of a reputable company with high quality products that sells Pau d' Arco??

Thanks,

Midge
