I've been to a chiropractor.

The woman claimed basil essential oil could be used in place of: ibuprofen, hand sanitizer, soap, and a few other things.

That's right, not only was she a chiropractor; she was an essential oil salesperson.

Snake oil. Chiropractors are snake oil salesman, no different from TCM peddlers. I think TCM peddlers are actually, at least in the U.S. where you can't sell water that's had dead animals fermenting in it, better because acupuncture won't permanently damage you. It just gives you that nice placebo.
