Anyone with Candida is B1 deficient, you can't add more to your diet since you can't absorb it. You can't inject it because the pathways for it don't exist. Many things get fixed with Benfotiamine including the fact that Candida cannot use this form of B1.
I loved Pau D' Arco, mainly because it really works to keep biofilm candida under control. But you need to coffee enema to remove the toxic nucleic acids those Candida all carry.
See my post to Trapper below with a link to frqs, or use the Doctrine or stay with Pau D' Arco but you won't win that battle without detox like CEs...
