since begining of time, we dont have a herb seller who can help with inflation and ease to get herbs in a little time.

That's because herbs are designed to be farmed by players. The herbs and the potions you can mix from them were an experiment to build a player-based crafting economy.

Farming herbs is a task which can be performed on any level. So when you need a large quantity of them and you have cash to spare, then how about paying some low-level newbies to farm them for you?
