Trapper has great advice there. I have suggested adding Cayenne Pepper, Cinnamon, and Apple Cider Vinegar to the oregeno oil and collidal silver for some real nasties that have been going around and it really helped. I think all of these ingredients that might help in the short term but also drink as much distilled water as you can stand.
I you don't if you make your own Colloidal Silver , but if you do not, I would suggest ordering a gallon from Ebay. You get a gall for what amounts to three swallows from the Helath Food Store.
