Charlemagne Hua was a Human male alive in the 22nd century. Tall, with a thin mustache and hair swept into a ponytail that was always seemed on the verge of coming undone, he provided drugs to colony worlds on the edges of Federation space where law and order was not as well established.

In his dealings with the Orion Syndicate Hua came to realize that the hormones secreted by Orion females could be synthesized and used as components in drugs that other races could take. Working with Jofirek he managed to do so, and called his invention the Venus drug. (ENT - Rise of the Federation novel: Tower of Babel, TOS episode: "Mudd's Women")
