yes indeed you guys sound like ur on the right road. Im a newb too but we just got finished making our with Noman Tek. Once you have gotton your jar of strained naptha put in freezer ,within at least 2 hours you should see crystals growing right away . leave it over night . Check in morning filter through coffee filter keep the old naptha , use a rubber spachula to scape all the spice onto a clean coffee filter ,,, let dry .. then you can either A ' do an amonia rinse or go straight to recrystalization. WE tryed both , Just note its alot ezer on the lungs with some weed Pm me if you have any other Q's

SWIK added a bunch more lye and the solution finally turned a very dark grey almost black color... after adding the naptha I can see the naptha has now gained some mass... My friend also says that when he went out to check the evap tray from the last extraction he noticed now that the naptha is completely gone it has left a thin flim on the glass almost ilke well... it looks like dried sperm to be honest, and he says it smells kinds like a superball a synthetic rubery smell but its completely white/clear... so how long should he wait to start scraping it up? and also what can be expected from the first hit? This will be the very first time he has EVER tried this substance, and after obsessing for year and finally taking the time to hunt everything down it seems to almost be ready... any advice? He has procured a metal freebase pipe and has no weed but does have cigs what should he do to go about smoking it, and how much should he hit for his first time?

well y0u definitly wanna make sure you take a good hit otherwise you will just get to that body stone high . You will know once you get ' the Trip' i dont know if i would try with tobacco?? but if thats all you have then do it, Cuz the smoke is rank man like the worst plastic taste ever !!! but with weed you dont even taste it

Tobacco has shown to have very adverse effects! Do not smoke with tobacco!

is it preferable to use whole mimosa bark or powdered mimosa?
i plan on ordering 1# of either and attempting my first extraction soon. my gut feeling says to go with whole bark, but i'm new to all of this.

I prefer the powdered, it provides more surface area for the various chemicals to react with. However, whole bark is easily powdered in a cheapo coffee grinder, so buy what's cheaper!

Active ingredients sourced from within the UK?
swim can't search at work for these things easily so I apologize in advance.
Can swim source a "spice" yealding plant from withing the UK or is it a buy the seeds over teh interwebz jobby only? swim can extract myself but sourcing the ingrediants with limited internet access is proving a bit of a mish.
Any help suggestions welcomed
p.s this forum has a cozy feel about it.

thanks for the reply. my friend is pretty new to chemistry, but he was a chef for 6 years. with cooking, pre-powdered spices are usually a no-no, since they lose their potency over time. also he thinks he remembers someone mentioning that the pre-powdered stuff may contain subpar bark-- so he thinks he will just order the bark whole and grind it himself in the blender. he thinks the "crush ice" setting should do fine.
my friend also asked me to inquire about a food-grade tek? he remembers hearing something about using food grade acids and solvents to extract the spice rather than the more toxic chemicals? SWIM is very concerned about inhalation of toxic chemicals.

I´m trying to realize an A/B Extraktion using MHRB, Muratic Acid, Heptane & Lye, freeze precip.
I allready have 90g MHRB well chopped & blended that soaked for more or less 24h in an 500ml Water - Muratic Acid Solution at ph2, meanwhile stirred & swirled and now seperated severeal times leaving behind 440 ml clear reddish liquid that is finally after filtering & seperation, more or less clear that there is even some root dust, that might be seperated later.
Under which circumstances is DEFAT reasonable ?
Several A/B Teks advise to heat the Naptha/Heptane and basyfied solution before & during the "pull", other dont talk about heating or heating just the Heptane/naptha, some advise to put Naptha before basifying, some say after ! Should the pull be swirled and lend over or even shaked ? Some give time for seperation about minutes, hours, days with & without heat. Is 1/10 heptane of solution for each pull ok for an freeze precip, every pull frozen seperate ! 400ml basyfied Soultion = 40ml heptane per pull ?
- How do you keep this ?
After reading several a/b teks i read many different things on this topic especially about the "pull" there are so many ways to do it, what do you think is advisable, by using hexan and muratic acid, are there some advantages that the one or other way is reasonable?
Comments appreciated !

Finally today i decided to do no DFAT and did directly 2 Pulls (20ml & 22ml) with Heptane on 200ml Muratic Acid Extract (containing approximately 45g MHRB extract). I didn`t heat the solvents, but i put the 20ml heptane into the solution before basifying with a ph13 solution of lye, checked the final ph and swirled & turned the solution containing jar for 7 minutes. After swriling & turning I gave it 15-30min for seperation, then I sucked the toplayer with a syringe and put it into another jar. For the 2nd pull I used 22ml and gave some more lye to reheat, into the jar. The 2nd pull was combined with the first one, that lead to an amount of round about 42ml heptane, from 2 pulls on 200ml basyfied solvent.
I let the 44ml heptane extract sit for 1 hour or so to evaporate the solvent until the solution wents milky, but it didn`t evaporated very well. I think because of the tiny surface inside the jar and it didn`t turned milky also. After an hour and small evaporation (5-10%) i blew slowly some air with my mouth into the jar over it`s surface, to my surprise milky clouds appeart inside the soultion and in some more seconds it increased and turned the soultion very milky white. After waiting 1 hour more, the milky clouds disappered more or less, but the solvent was still slighly milky. Again i gently blew some air into the glass and again the milky clouds build up and the solution again turned into very milky white.
I decided that the solution might be saturated enough and put it at -28°c into the freezer and will wait 24h an then have look.
Why the milky clouds are not staying, maybe the solution is already saturated well, what do you think ?
opinions, guessues are welcome !

I would really appreciate if someone could reply to my question or guess the amount of Spice on the Pictures above.
I don`t really know, what might went wrong, i think it might be the MHRB, i bought it on a Market in Brasil, so maybe its very bad plant material. After i seperated the dmt pictured above, i let the rest of solvent evaporate, it brought just some yellow goo, that is already smoked (the spice too), the goo smell & taste was very dmt like, the spice also tasted and smelled like dmt, but the effect was not very strong ( I think because of the amount). But definetly absolute pure the taste was very soft, not harsh at all. After this, i pulled several times more, it brought goo or a very low yeild 1-5 mg i guess, that is really sad. After 7 pulls all in all, i basified the other 200ml of my acid extraction (the original was 400ml and divided in two pieces 200ml) I pulled from this batch with heated heptane this time. 3 Pulls were done and freezeprecripated and brought yellow goo and again a very low yeild of white dmt, i guess half of the amount in the pictures above. I did several pulls more, with heating, without heating, pulling 30min up to 3 Hours, the result was all in all nothing or just some crystalls, or yellow goo. After this i evaporated the rest of the heptane, but evaporation brought never crystalls to me, just goo, or a very small "film" of a transparent liquid that smelled very intense like dmt but, no crystalls formed. (Evaporation was done JUST after freezeprecip dindn`t work or just brought low yield, never direct after pulling)
So after all this mess i tried to checkout what stb will bring to me! 25g of the same MHRB were prepared (half chopped fibrous, half powdered my blender didn`t managed to powder it all.) So i added a solution of 25g NAOH and 375ml distilled water and let it sit for 4 hours with occasinal stirring and shaking. The MImosa didnt resolved completly in the soultion but the main plant material was resolved, just on the bottom some black plant goo seperated, which i stirred up to liberate any alkloids. After 4 Hours i pulled with 25ml warm heptane, after 15 minutes of stirring and turning the jar upside down, rolling on the ground, it let it seperate for 10 minutes, a dsitinct layer formed and so i took the hepatne off with a syringe. I pulled three times with 25ml heated heptane (bestine) and the solvents went together into a evap dish i guess 75ml all in all, but a little solvent was left behind in the jar. I put an old t-shirt over the dish to protect the solvent. Let is sit for 12 hours outside and more or less 6°c without artifical ventilation!, When i lopked at it after 12 hours, i wasn`t not able to estimate if there evaporated anything, there was still alot solvent inside, no crystalls. So it let it sit for more 8-10 h in my room without any artifical ventilation at 22°c. After this 8 Hours the solvent was evapped and many dust & hair particles can bee seen on the dish (its definetly dust & hair not spice) But also there is some remaining Liquid Film that is transparent, but smelled not much dmt like, more solvent like. So i left this more 12hours outside at 6°c over night, i thought the cold might help the dmt to from crystalls. So today i took the dish inside, nothing changed in the dish, still hair & dust, and this very small film of liquid and some liquid drops, BUT now it`s smelling very intense like dmt, no solvent anymore. But there are no crystall that can bee seen.
Here is picture how the dish is looking right now.
What should i do with this dish, wait more ? I mean there is a very intense dmt smell, there must be dmt on the dish, but i cant see crystalls just this transparent liquid film & some hairs & dust... why is spice not crystalizing ?
Some how i arranged the whole process a little bit chaotic, doing A/B then switching to STB because of LOW Yield. Finally i can say the first A/B Extract (pictures above) brought the most succesfull yield, but it is still ridicolous because of the very low yield. I changed the way of pullin during A/B Extraction and tested many things, nothing lead to an reconizable amount of dmt.
I`m really hoping that i will get the dmt in the dish crystalized, maybe i should wash the dish with hot heptane and make a freeze precip, What should i do, what would you do?
I think i will wait until i resolved the situation with the dish and after that i will Start a New attempt to extract the sacred spice . I will document the next extraction very detailed with pictures and notes, depending on the result i will open a thread to ask folks here to analyse my process, to examin the "mistake".
Another thing is the Materila i got, i bought two tipes of rootbark on this market in brasil, both were sold as JUREMA but they are looking a little bit different. Both seem to be a Type of Mimosa, but im not certain if BOTH are MHRB. Look at the pictures and post your opinion, please !
This one i used for the extractions it was sold as JUREMA "PRETA", and contains DMT, but regarding to my result not much at all, but maybe it`s my process and not the plant.
This one was sold in another shop as JUREMA "Branca" it appears a little bit more purble/pink/orange and the outside bark texture is very different from the other bark, maybe it is more potent, i hope so. But i didn`t used it yet, so i have no confirmation that it contains dmt !
Please help me, i would really appreciate if someone could reply on this, it seems more and more im talking to my self.
Thank you very much

How certain are you that the material you have is rootbark? You're process sounds more or less correct.
Both jurema preta and jurema branca have DMT in the rootbark. Jurema preta is Mimosa hostilis, and has been analyzed as having 0.5-3% DMT per weight. Jurema branca is Mimosa verrucosa, which hasn't been analyzed for DMT, but it has been sold as Mimosa hostilis, and people have been successfully extracting DMT from it.
If you're sure that the bark you have is rootbark, either do some more acid pulls on the bark, or add more lye and pull with nonpolar solvent again. If the DMT didn't extract, and it's not left in the roots you acid-extracted, then it must still be in the lye solution.

I`m hopping it`s ROOTBark, what i can tell with certainty is, that it is bark, if it`s really root bark i can`t tell. I mean the pictures i posted look pretty mich like the rootbark pictures on erowid. I think if it is just bark, it would look different, i hope so. Maybe someone can ensure me with the help off the pictures i posted, that it is rootbark and not bark. I mean i bought the bark on a market in north-east brasil were all types of flowers and roots and stuff for Brazilian Spiriuality is sold and i supposed it will be the "real-stuff"! So i expect it to be rootbark, maybe i asked if its root-bark but i don`t remember anymore. I´m pretty aware that the bark it self contains not much dmt in relation to the ROOTbark. Maybe youre right and they sold bark and not rootbark, that might explain the low yielding. I think with the next extraction attempt i will use the other "root" bark (2nd bark picture). If it`s not working, well i will thing about to post my detailed extraction procedure to get an examination, but yeah like you already said, i´m almost certain that i didn`t do much wrong. I really read a lot of extraction teks, old and new ones almost every tek ill found on the web, also a plenty of threads in this forum for about 3-4 month before my first attempt. So i will leave it to an new attempt with the other material and maybe order some material from the vendors that are advised in this Forum.
Some opinions about my evap dish that smells very intense like dmt but contains no cristalls just this transparent liquid that is pretty much "glued" on the evap dish, why cristalls are not forming ?
BTW: After the 3 pulls from my STB attempt (see evap dish) i did one more pull, i left this pull for about 48h in the jar, now took the heptane off and will do a freezeprecip with the 4th pull. I will wait until the solution becomes milky and then it will go into the freezer.
entropymancer, thanks for breaking the silence, and i will remember your advise the next time. But genrally i´m certain that acid and lye was enough. Acid extraction was 48h at ph 2 (without heating to avoid lower ph`s) with Muratic Acid (Hydrocloric Acid) basification was done to ph 12.5, checked out with ph-Meter, solution turned white -> black as described. STB i didn`t check the ph because of proportional use of lye i expected it will be sufficient, but anyway solution turned white -> black, and was definitv caustic.
But please any comment to the evap dish (see picture) it smells the hell of dmt but there are no cristalls just this strange sticky transparent liquid (probably molten DMT ?)

Total chemistry noob here. I'm contemplating my first extraction. I've got 1lb MHRB and am looking at doing the following A/B extraction.
My question is, would I be wise to extract a little at a time, say 50g bark, then 200g, then 210g? Or should I just do it all in one run? I'd like to get it all done in one go--don't want to have my place smelling like vinegar and paint thinner more often than it needs to. But if the general consensus is that it behooves first timers to start small lest they waste that expensive rootbark, then I'll opt for that choice.
I am also kinda tempted to go for 1lb at once since that is the amount called for in the TEK I've chosen.
Thoughts?

Do 50g, see how it goes and then figure out how you're going to do 10X that much.
That's a good tek, BTW.
That's a good tek, BTW.
That TEK takes a bit longer than Noman's so SWIM thinks that would make SWIY more inclined to try more.
The big factor in determining how much to start with is how bad it is for SWIY if SWIY has to shell out cash for a new batch, and wait. If that doesn't bug SWIY then start big (maybe 1/3 to one half?), but remember SWIY will get higher yields as time goes on and gains more experience with these things. (Also if SWIY screws up really bad he/she could end up with zero product!)

Good advice, thanks. SWIM'll start with 50g. SWIM will also start calling SWIMself SWIM even though SWIM doesn't quite get the significance of switching pronouns around

hey zazen
here in Dreamland many times what they sell in the market is not rootbark, its the treebark.. It does contain some dmt but not like rootbark, and apparently more tannins/oils than rootbark..(which maybe explains also why the oily film in the evap dish)
I can tell you one thing.. SWIM definitely always says go for freeze precip instead of evapping, since it is better to making crystals, evap can make this oily film..
What SWIM has noticed is this oily film can become crystals, but it is as if there is a surface tension that sort of protects it from properly evapping. The first time SWIM extracted when he tried evaping and had same problem, what he did was sratching a bit the oil, breaking up some of this surface protection, letting it evap a bit longer, and then at some point some crystals started forming, but some oil still remained.. Then SWIM scrapped the oil/little crystals, and put it on the sides of a plate, and ocasionally re-scrapped it and put it on another position on the side of the plate (can you visualise ?).. Crystals eventually formed..
OR.. maybe easier and more recommended way.. Boil some water, wait to cool a little.. Put small amount of solvent in a glass (like lets say, 30ml), submerge the bottom of the glass in the hot water for like 30 secs, the solvent should get hot, then put this solvent on the evapping tray with the oil.. the oil should dissolve (if it doesnt, maybe you need a bit more solvent).. Then suck this all back with a pippete and put in a small container (can be a shot glass), cover and into the freezer... next day take it out of the fridge, quickly scrape the crystals off the side and pour into another glass where a coffee filter is already attached, so the crystals will stay in the coffee filter and the solvent will pass through..
