I Am Recovering From A Recent (emergency) Hospitalization For A

I am recovering from a recent (emergency) hospitalization for a kidney infection...In fact, twice in the last three months. The bacteria is very resistant, and is named ESBL. I am 60 years old, and have been in very good and strong health previous to this problem. The doctor has put me on a preventative antibiotic for three or four months. Oil of oregano capsules have been recommended to me by a trusted homeopathic therapist. Do you have any thoughts on this?
