Perfect juju woodcutting potion

A Perfect juju woodcutting potion is a potion made using the Herblore skill. It is made by combining a juju woodcutting potion (3) with harmony moss, requiring 75 Herblore and giving 120 experience. This makes a three dose potion, and it can be decanted into other doses by talking to Bob Barter (herbs). It can also be turned into a six-dose Perfect juju woodcutting flask by talking to Teplin Macagan with a potion flask.

A dose of the potion is believed to last for one hour. While the potion is in effect, you have a 5% chance of getting two logs from a tree instead of one, giving twice as much experience.
