Allowing a brew to settle in the fridge for 1 week allows the nausea causing sediment and tannins to fall to the bottom, allowing one to decant off the top liquid from the sediment. This process is long in the fridge in a very tall tall mason jar (1.5 to 2 liter masons wori the best), I have used the method for years, it does actually take about 7 days, but works. The tannins in the brew irritate the intestines causing one to throw up or become nauseated, some people like this effect, others not so much, everyone's preference is different.
If you don't like nausea causing sediment or tannins in your caapi brew, i've seen 'pure alkaloid caapi extracts' (just google) on the net for less than six dollars, the extracts give me zero nausea even at 280-350mg, highly recommended if you have a sensitive stomach like myself.
For many years I used to brew caapi and let it sit in the fridge for a week to let the sediment settle to the bottom, but now I find extracts of the woody vine to be just as effective and nausea free as the way I used to brew using the fridge for a week. I learned how to brew some 10 years ago by following the methods of Sync and Meteor and Napolean Blownapart at the old classic ayahuasca forums. I start early in the day, first I pray and walk in nature for an hour, then take the 1 and 1/5th extract early in the afternoon for an all day strong vine presence. I have been learning to cope with the death of a beloved one for several months now, and I find walking for long periods, solitude and taking a heavy caapi brew or extract every 2 weeks to help immensely. Death and Loss is very difficult, it is something that I don't think anyone ever gets over.
A person carries it with themselves for the rest of their life, but rest assured that life continues after death, for all of God's living creatures, so said Pope Frances recently to a crying boy whose dog died on the news just the other week, and I trust the Pope.
You may remember me as 69Ron. I was suspended years ago for selling bunk products under false pretenses. I try to sneak back from time to time under different names, but unfortunately, the moderators of the DMT-Nexus are infinitely smarter than I am.
If you see me at the waterpark, please say hello. I'll be the delusional 50 something in the American flag Speedo, oiling up his monster guns while responding to imaginary requests for selfies from invisible teenage girls.
