For my intro to ayahuasca I boiled up 50g of white caapi thoroughly. It's definately a very kind teacher. All that stuff I have heard about the violent purging and body spasms just aren't present with this brew. Sure you can purge with it if you want to, but it will be a deep comfortable purge that will happen well into the experience as a result of your body's chemistry changing, rather than that of an upset stomach. I actually even quite like the taste.
My intentions with this first brew were to feel the effects of the brew only, but after an hour or so meditating on it I loaded a small amount of spice into my pipe and inhaled. It turns out the caapi did way more than I at first thought, it's that gentle.
Anyway I simmered the 50g's very lightly with no acid 3x3 hours then reduced and from the very first time I smelled the steam I was in love. I never thought I could get so much pleasure and fulfilment out of gently stirring a pan for all the waking hours of a whole day, but I highly recommend giving the magic all the attention in the world.
