Talchok musk was a type of cologne, presumably made from or by talchoks.

Neelix possessed a vial of talchok musk, which he described as having a "very enticing scent". In 2374, Neelix wore some for a "little romantic rendezvous" with a Mari named Talli. Tom Paris, who did not find the scent appealing, thought that it was "certainly...musky." (VOY: "Random Thoughts")
