Anti-depression product name?

[tim]

Hey
I'm trying to come up with a name for an anti-depression product for my science project (the product is fictional and this project is important). The fictional product isn't a conventional drug, but rather a sort of supplement which is drunk as opposed to taken in pills. I don't want to include the word "depression" in the name of the product. Any ideas, please? (note: i can't use a trademarked/copyrighted name as i will lose marks)

(the product is a liquid. the user must pour around 5 drops of it into a little bit of water)
