Pau d'Arco and C. Diff
The term C. diff is a short form of C. difficile, which is the name of a bacteria. In this case, it refers to an infection of that particular bacteria. If a person has this in his body, and a course of antibiotics kills off other bacteria that would have competed with it, then it can lead to serious issues.

Are you wondering how this herb relates to this particular infection? There is no evidence from research (known to this author) that proves C. diff can be treated with Pau d'Arco. Some people have made claims that the herb attacks this bacteria while leaving alone others that are considered beneficial.
That aside, keep in mind that for C. diff treatment, a doctor often prescribes certain antibiotics. Pau d'Arco is often recommended by herbalists as something to be taken when a person goes through a course of antibiotics. For one, this is intended to keep away yeast infections that might show up when taking this type of medication. In addition to that, some people just think that Pau d'Arco is useful for general health.
What to do?
Have a conversation with your doctor about Pau d'Arco and its potential use in your situation involving C. diff, whether related to the illness itself or as a measure against side effects of the medication you take. Don't try to self-prescribe what you think might be useful, especially based on what you read on this website.
