Yeah, though at this point, I think that's becoming less useful. Tisane as a term is essentially dead outside of very niche circles, and tea has replaced it in pretty much all common usage. This, btw, isn't me disagreeing with you, it's an expansion on the subject.

At some point, with the word tea not being a formal scientific term, it being technically correct only for one plant type starts to not be true. I don't think it's there yet, but it's moving that direction.

But, that's going to be a long time. We're still at the point where you have to specify if you want tea from other plants by prefixing the type of plant with it, while camellia is the default. But it is starting to be a thing where more and more people think of tea as a brewed/steeped product rather than an infusion of one plant.

What I wonder is if it'll be something like where people call chai chai tea, and we'll have to order tea tea lol.

It's been a thing in my lifetime where some people weren't even aware that anything other than black tea exists. Here in the mountains of the us, if it wasn't iced sweet tea, you were drinking some kind of herbal tea hot. There was no green tea, and finding anyone that knew that there was more than one type of black tea was unusual. Now, our little town has a tea shop with maybe thirty types of camellia products ranging from white to green to black, different varieties, all kinds of stuff.

Gonna be interesting how the language of it shifts. I won't likely live long enough to see it change all the way though
