Herblore.

[Pebbles]

Can anyone tell me what's the fastest but cheapest potion to make to level herblore for a level 42?
Thanks!

I think energy pots are really cheap at the moment to make, but they take a while to sell from what I've been told. If you want cheap exp, serum 207 (or whatever they're called) are good, but the problem is they can't be sold.

okay, thank you. =]

No problem

Gp/xp ratios of all commonly made pots:

Good for picking a currently cheap one.

I'd say regular restore potions.
