Trillium was a substance that was regularly being traded in the 23rd and 24th century.
In 2267, Spock posed as a trader of kevas and trillium while on Organia. (TOS: "Errand of Mercy")
Later, in 2373, Arne Darvin made the same claim while aboard the USS Defiant. (DS9: "Trials and Tribble-ations")
In the novelization of "Errand of Mercy" in Star Trek 2, Spock described trillium as "a medicinal plant of the lily family", as in the real-world trillium, while Darvin's quote ("I'm a merchant. I deal in gemstones, kevas and trillium mostly.") would seem to suggest that it was a mineral.
