Pau d'arco or Taheebo, as it is also called, is not all created equally. If you go down to your local health food store you will probably find numerous brands of Pau d'arco in many different forms. You’ll see Pau d’arco liquid, Pau d’arco capsules, Pau d’arco tea, etc. All of them will claim to be pure Pau d’arco. The unfortunate truth is that many of these products are not true Pau d’arco and, even worse, some are just sawdust. If, for whatever reason, you’ve decided to pursue a course of tak.
