you're talking about this: https://en.wikipedia.org/wiki/TCP_(antiseptic)
Based on the context, I now think the person was gargling the antiseptic called TCP, which is really phenol (a totally different chemical from TCP). So I think I understand the confusion now.
When using TLAs for chemicals, it's often better to write out the full chemical name instead. When I say "IPA" I mean isopropyl alcohol but everything thinks I mean beer.
In the UK, if you say "TCP" everybody knows that you're talking about the antiseptic phenolic liquid that can be used for gargling but never swallowed. It's present in most househould medicine cabinets.
It's important to note here, given that the subject is loss of the sense of taste and smell, that this stuff absolutely reeks.
Somewhere around April/May, everyone in my circles and all their dogs were suddenly talking about "IPA". I was very, very confused until I eventually figured out they didn't mean the beer.
Doesn't sound like something one should gargle tho.

> TCP is recognized in California as a human carcinogen, and extensive animal studies have shown that it causes cancer.
They also say that about coffee in California.

It really isn't that bad to gargle but not particularly pleasant either. It is effective though and that's the real point.

No, not if the "risks" is comically small. The warning label becomes meaningless when applied to anything with an astronomically low chance of causing cancer.
It's literally a medical antiseptic designed to be gargled after dilution.
