I have a pressure cooker that I love using and was wondering if there's any advantage in adding a pressure cooked acid boil to the earthwalker tek using acuminata root bark?

i dont see how it wouldnt help..

acuminata root bark??

Yes, acacia acuminata

In Cyb's Max ION tek, a PC is used.
Some report 3x45min PC boils help breaking more the bark and having a greater yield.
My tough are it's can usefull, but not mandatory.
3 or 4 long boil and reduce are effective so.
Depending on the timeyou have and material, it can be helpfull for you, or not ..
Powdering root bark really help.

That kind of pressure helps lyse the cell which is what cooking is all really about? Breaking down cell walls to let the DMT out. Obviously the more surface area around the cell the easier this can let the DMT flow out in to the solution.

Usually i read people only needing one or two pressure cookes instead of 3-4 acid boils.
