OK sorry guess I wasn't articulate enough.
I prefer caapi but rue is more economical.
take 50g b caapi shredded, brew in a teabag in a good sized pot. Do not use any acid like vinegar, it is not necessary.
Every 30 minutes remove the tea you made, and put in a bigger pot. Extract from the teabag 4 times or until it stops giving a color to the water. 4 is usually enough. What you do is you take all the liquid tea you extracted at the end and simmer it down to a cup to drink.
Mimosa hostilis does not need to be cooked that long, because it will make your brew disgusting. Experiment with adding the mimosa to your pot in another tea bag shredded decently after the first caapi pull, and the second.
For example, when you remove your water from the pot the first time, its now time to add the mimosa, and cook them together.
Try this, and also try next time adding the mimosa bag to the brew after 2 pulls. See which one you like better effects and taste-wise.
That's really all you need to do. Like I said, if you use rue, you probably don't need to cook as long as caapi. I think that's all the info you really need. You can boil it, it won't destroy the alkaloids, it just causes sugars in the plants to caramelize and taste all nasty. So a simmer is preferred. Enjoy.
