Natural remedies like... taking small doses of the thing you're allergic to in order to desensitize yourself? Because that's what the immunotherapy I'm talking about is. Not "exotic chemical solutions".
It's always the people who decry medicines, i.e. highly pure, intensely tested dosages of chemicals, as "exotic chemicals" while in the same breath advancing "natural medicines", i.e. wildly variable dosages of hundreds of random molecules. Some people seem to think "chemical" is something artificial and bad while "natural" is somehow a rainbow of goodness and not the result of insanely complicated biochemistry.
