Hurtingboy,
Believe me, it's no different here in Ireland. I have been treated with the same contempt when I mentioned herbs as a possible treatment. It's not until you point out that some very well known 'conventional' drugs are based on herbs that the conversation usually becomes silent. In all credit to Dr. Hennenfent, he is the only one that allowed me to say that it worked for me, and is prepared to keep an open mind. I appreciate that.
It is not necessarily a good idea to mix conventional antibiotics with herbs. The particular antibiotic that you have been prescribed didn't work for me. In fact, I had an allergic skin reaction to it, and had to stop taking it. The best of luck.
