There were some old threads about this approach, but I am not able to find it now.
However, it's quite simple: make a brew, reduce it to low volume (when it become syrupy), add ethanol to precipitate mucilage. Use any strong ethanol, imo resulting liquid should be 80-90%, do not forget that cactus syrup still have some water in it.
Separate it by decanting and filtration, cactus goods will stay in liquid. Cool the liquid, more sediment could form (even crystaline, but it's not mescaline
), separate liquid again and evaporate it.
Result is a crude cactus extract with very interesting (really awful) taste, but do not try to taste it, put it into the capsules. It will not be dry material, more like thick honey, it seems to be also hygroscopic ( my guess is that due to presence of some sugars or salts), it can dissolve the capsules, so do not store in them too long.
There will be some nausea most likely, be ready for it. Ime cactus nausea is not that strong, and can be diminished by eating some small bites of fruits or vegetables (tomatoes are great). Do not fast before ingestion.
Cut and pasted this from another board. It seems similar.

This is a method I’ve talked about before but was hesitant until recently to post because it didn’t work well for all cacti types, most but not all. Now I have found an extra step to ensure a clean end product.
—————
Take your fresh cactus and de-spine only if it’s a species with large in-the-way spines, otherwise don’t worry about it. Cut it into slices like a loaf of bread, thin as you can without making it a hassle, especially if you have a lot to cut. Once you have your slices, cut them into fourths and place into mason jar/s leaving a little room at the top.
Mix up 50/50 solution of distilled vinegar and distilled water, pour in just enough to cover the cacti material. Now let these jar/s set with occasional shaking (often as you remember) for 2-3 weeks. Once finished decant off the solution through a fine metal mesh filter, don’t try to use a coffee filter it’s too viscous.
As it pours take note of its viscosity, they’ll always have some viscosity to them but look for times where it comes out almost as a gel. (You’ll learn the more times you do this TEK.) This will be one indicator whether you’ll need to do the additional step I speak of below.
You can do a second soak on the cacti material for another 1-2wks for a yield that will equal about 30% of your first, note the second soak will pull many more impurities as well.
Take these water/vinegar extractions and dry them in a glass Pyrex tray, preferably with a heating fan to speed it up. Some fan at least, heating element or not..
Once fully dry, add a minimal amount of distilled water (you can always add more, you can’t take away less) and scrape up, stir and swirl the extract with the water to dissolve the very soluble alkaloids. It’s ok to not dissolve everything, but try to get close while using minimal amount of water to do it. Even better to use water you’ve warmed a bit over the stove. Once again take note of the viscosity, is it fairly liquid or literal snot/mucus?
Decant off solution into a taller possibly skinny container, put this in the fridge. We want to precipitate out the garbage, the acetate alkaloids are soluble enough to not precipitate. Leave for 48hrs. Upon returning very carefully decant off the solution into the glass Pyrex tray and again dry out completely.
Now that we’ve dried a second time it can either be used as is or a second step can be performed. Most of the time this second step isn’t needed, but if the cacti used has alot of fats/lipids/crap? the end extract will be much less pure and nearly impossible to reconstitute and use in water without vomiting from the cum like texture. You can scrape up the product first and see if the yield/purity seems acceptable. No matter what this next step won’t hurt.
Step 2 involves scraping up the extract best you can in the dish, then add some alcohol, methanol 99%, ethanol 96% or isopropyl 99%. A minimal amount but still more generous then the water used in the last step, the insoluble impurities are really insoluble in the alcohols so it’s not nearly as important and the alcohol will begin evaporating quickly too.
Scrape/stir/swirl the alcohol best you can, notice how the extract loses its color and becomes pale insoluble garbage while the alcohol takes on the color of the extract. Look for that color in any extract in the pan and make sure it seems fully saturated and pale of color by the time your done.
Carefully decant off this liquid, this time through a coffee filter. Expect some time for filtration, maybe 30-90min. Let it pour into a clean glass Pyrex. Once again let dry fully to have your final product.
Using this method it’s possible to get extract that usually is used in doses of 1-3g. It can often fit in 5-10 capsules or be reconstituted in an easy to take (yet still not pleasant, just nowhere near as bad) shot of liquid. Obviously YMMV with variation in cacti potency, extraction variables, etc.
In the end this is the way to do it. This has even been tried doing this the other way around with the alcohol pulls first, much more impurities come over. This is the best way to easy-to-consume crude extract.
