A somewhat standard schpiel I’ve posted before is to note that the average kitchen cupboard and spice rack is a veritable cornucopia of antimicrobials and anti-inflammatories. Understanding this as well as the proper use of them for these purposes would be very useful knowledge for just about anyone. Garlic, oregano, vinegar, salt, pepper, honey, sugar, turmeric, cinnamon, clove, curry ... It’s no accident.
Just about everything in Italian vinegar and oil salad dressing kills bacteria, as well it should since it goes on raw vegetables for consumption. Salt cures meats for the same reason, as does sugar. Pickling is preservative as well, vinegar. There are medicinal uses for all of these.
In the face of an outbreak of antibiotic resistant bacteria, you’ll need all the help you can get. If new antibiotics to overcome resistance are not neing introduced, it’s just a matter of time. MRSA already has flareups in public places, from hospitals to high school gym locker rooms to health clubs.
If that doesn't work, battery acid will, but you better be ready for that because it hurts.
