One of the new activities coming to v0.5 is potion bounties, which will task the player with delivering a semi-random set of potions for a much larger sum of G then you'd get selling them. This will also help you earn favor with a specific faction in the game, which will ultimately lead to new opportunities (lewd and otherwise).
Note the checkmarks: green if you have the relevant potion on hand, black if you are able to make it with the ingredients you have in your pouch. If you can't make the potion, there won't be a checkmark at all.
