Slug-o-Cola
Slug-o-Cola was a brand of Ferengi beverage which contains 43% live algae in every bottle. It is an opaque mint green-colored drink, usually served without ice. The primary slogan of Slug-o-Cola had remained unchanged since 2074: 

"Drink Slug-o-Cola!  The slimiest cola in the galaxy!" 

In 2374, the chairman of Slug-o-Cola was Ferengi Commerce Authority Commissioner Nilva. That year, Slug-o-Cola had been losing ground to its primary competitor, Eelwasser. Quark, while disguised as Zek's female financial advisor, "Lumba", suggested to Nilva that he might improve his sales by advertising to females, with a new slogan:

"Drink Slug-o-Cola, and keep your teeth that lovely shade of green." ()
