bad idea
Sorry TC12 I have to disagree with you. I think it's a crazy idea to mix prescriptive drugs with herbs. On what basis do you give this information?
One really important contraindication is that if you are taking doxycycline as I just stated that I am (together with iodoquinol) for the treatment of dientamoeba fragilis you must not take it with zinc. Pumpkin seeds for example, which many people are taking as a vermifuge are high in zinc. This drug must not be taken with calcium either.
