Inspired by this question about Romulan ale, I have a question about Klingon aphrodisiacs. After receiving a bottle of Romulan ale as a birthday present from Bones in Star Trek II, Capt. Kirk points out that the ale is illegal, and a little later, he wonders aloud what will be inside the doctor's second present: "Klingon aphrodisiacs?"
Romulan ale became a running gag of sorts in Star Trek. It featured notably in Star Trek VI and has been referenced numerous other times. It was even sold in the real world. Like Kirk, I got some as a birthday present. It was the worst beer I have ever had.
I assume that nobody is selling Klingon aphrodisiacs licensed by Paramount, but have such substances ever actually appeared in Star Trek canon? Given how revolting Klingon food is supposed to appear to viewers, I cannot help but wonder what luxuries used for more intimate purposes might be like.
