One thing to note in this article that covers the various options available, however I'm pretty much in agreement. When it comes to RS gold juju-farming potions go, they're good addition to any herb run. They give a 1 in 3 chance to collect 2 herbs at each time. I'm not able to do one with less than 50 herbs from 5 patches unless there's a death. My highest number is 70.
However, as Leaf says, it's unnecessary to be in Herblore's Camp Habitat just to make potions. I make them every week to get the quick bonus of finding all 10/13 jadinkos & any seeds that I discover that are planted and utilized.
They're only good for a few minutes thus the most efficient method I've come across for getting every patch with one dose of potion is to go to the Trollheim patch, drink an ounce of juju in the farming pot, repeat step Ectophial Teleport to Port Phasmatys & run to patch, REPEAT STEP the cabbage port (explorer ring) to Falador patch REPEAT STEP Cloak teleport to Ardougne Farm to REPEAT STEP, Camelot tab, run through buy Runescape gold to Catherby patch, REPEAT STEP. This doesn't leave much time to look around the scenery , so keep refilling buckets, talking about etc until after you've taken your harvest of Catherby.
