Symptoms from "companion" fragrances?

(dd) said:

Are there cases where fragrances that generally are considered safe but have appeared along with
harmful agents then produce symptoms on their own, something like Pavlov's dog?

In researching for "multiple chemical sensitivity", the researchers used a fragrance and an odorless
gas (I believe it was CO2) to produce breathing problems by lowering the O2 content of the air.

Later, in some people, the fragrance alone was enough to produce reports and symptoms of breathing
problems, even though it was in room air, not low-oxygen air.

Consider a janitor, whose long-standing use of cleaning solutions causes respiratory problems. If
the solutions had a fragrance, say lemon, would it be surprising if the fragrance brought on
symptoms by itself? Are there confirmed cases of that sort of development? Claims of it happening?

No confirmed cases, but it has happenhed during research.

Tsu,

I appreciate hearing about cases that confirm deductions. Hopefully, I'll find more documentation as
I continue to search.

Best, dd
