Something that was drawn to my attention regarding the content of this document was that there is no warnings about the materials discussed with regards to the dangers and effects of the materials produced, and not enough about the warnings about some of the chemicals used (in particular, shellite/naptha).
DMT is widely regarded as the most potent psychedelic drug known. As has been said by someone else, the term 'mind blowing' could have easily been invented to describe this drug. It is not a 'high', or a party drug or any such thing.
To briefly sum up some of the sorts of nasty experiences that a person can have under the influence, it ranges from an experience of dying, being torn apart by vicious animals, being probed and having strange implants installed by cold uncaring aliens, extreme experiences of humiliation...
Now, after reading that list, one might wonder why a person would be interested in using this drug at all... Well, basically, because things completely off the other end of the scale can also happen during the experience. Contact with happy elves or clown-like entities, exchanges with entities who wish to teach you something, healing experiences, positive contacts with aliens.
The way it affects people is extremely idiosyncratic, but I can say one thing that is common to all experiences - it is always humbling, the awesome potency of this drug should not be underestimated.
MONOAMINEOXIDASE INHIBITORS (MAOI's)
The use of monoamineoxidase inhibitors, such as syrian rue, banisteriopsis caapi or synthetics such as moclobemide, which is a common way to activate oral doses of DMT, should be done with great caution. There are elements in most people's diets and drug intakes which, when combined with the use of MAOIs can lead to a serious medical emergency if proper precautions are not taken prior to ingesting MAOIs.
Monoamineoxidase inhibitors (MAOIs) should not be taken in if any stimulants (caffeine, amphetamines, cathinone, methcathinone), or SSRI antidepressants (prozac, citalopram, zoloft etc) have been taken less than 48 hours beforehand, the same goes for beer and wines, and there are foods which contain proteins which are dangerous if consumed within the same period of time, these are generally aged protein products (wurst, jerky, salami) and yeast-based products, such as yeast extracts, wines, beers and other brewed or fermented materials. Bread is not so bad, since the yeast is still fairly fresh when it is eaten, but at least 12 hours should be witheld to avoid problems. The main issues are aged proteins, which covers brewed alcohols, aged protein foods, and SSRI's and amphetamines are contraindicated, though the info on the dangers regarding MAOIs mainly applies to synthetic MAOIs (eg moclobemide). I have been told that syrian rue and harmala do not cause significant risk with amphetamines and fresh yeast products, however they do potentiate amphetamines. It is best to avoid them if you are unsure or have not done small scale tests to ensure it is safe...
In most cases, one will only get a nasty headache, but it is best to avoid any of these things with MAOIs, recently a teenager made CBS news from mixing a MAOI with something of this nature (and of course the news people, not really interested in the propagation of safety information, didn't say what it was that caused the problem, however it would have been one of the above, as you can see it covers a lot of common foods and drugs).
What happens is the MAOIs prevent the action of the monoamineoxidase by preventing it from being synthesised, which stops these enzymes from breaking down chemicals in the brain and blood to prevent their levels building up too high. The natural cycle in plasma is of precursors, such as amino acids, being synthesised into neurotransmitters by enzymes, and these neurotransmitters only have a limited useful life in the blood as free radicals and other agents can break them and cause toxicity problems (which is the suspected but not officially recognised cause of people going bezerk on prozac), and so they must be removed after a certain amount of time. Also a number of chemicals cause dramatic changes in physiology, such as stimulants, and the protein tyramine, found in aged proteins, which is a product of yeast I believe, and the monoamineoxidase enzyme is responsible for protecting us from this toxicity.
When an incident occurs with MAOIs, a mild incident will involve a headache, but if too much poisons are in the blood when the MAOI is ingested, they remain active, and what is called a 'hypertensive crisis' occurs. This means severe headache, high blood pressure and heart rate. If the blood pressure gets too high, a stroke can occur, and beyond that, death from major brain haemorrhage.
SAFETY WITH CHEMICALS
In this document are described the use of numerous chemicals, the ones of most concern are the Non polar solvents (turpentine and naptha/shellite) and sodium hydroxide.
I recommend the use of solvent resistant gloves whenever contact may be had with the solvents. One should be able to find nitrile gloves in the supermarket, they are marketed as 'non allergy', some people are allergic to latex apparently (personally I hate latex anyway, it makes my eyes red), there is also neoprene gloves available, but these will be easily distinguished by being thicker and 'insulating' will be mentioned on the packaging somewhere. Nitrile is the best to use as it is highly resistant to turpentine and shellite.
Turpentine is not so bad, and being such a high boiling material, it's vapours are unlikely to develop to an extent to cause breathing problems. However, shellite is very volatile, more volatile than petrol, and probably more explosive than petrol.
No sources of flame or sparks should be present when working with all nonpolar solvents, and one should take care to avoid inhaling the vapours as much as possible. Always work in an area with good ventilation when working with shellite.
I have personally been burned by an explosion with shellite, it was only second-degree (the skin was fully damaged, but it hadn't gotten down to the flesh). I was in pain for three days, constantly spraying it with xylocaine spray to stop it from being so painful I was unable to fall asleep. It also put carbon all over the space that it exploded in. This was from inadequate ventilation and a spark from moving a pot around on an electric hotplate while blowing the vapours out of the pot. The vapours of shellite/naptha are heavier than air, so they will fall downwards, so it is particularly crucial that there is nothing incendiary below any amount of such materials at close to it's boiling point. The vapours will also flash back to the source of vapour for quite a distance, at least two metres clearance should be given before anything with a slight risk (including a mobile phone) of causing a spark should be permitted nearby. It is also for this reason that, unlike numerous other guides, I don't recommend heating the solvent when extracting. Besides everything else, experience tells me that one does not need to increase the solvation power of 300ml of naptha to get everything desirable out of an expected 1-3g yield. The only time when it is sensible to heat naptha is when recrystallising, and this can be done in open space using boiling water from a jug.
Sodium hydroxide (NaOH) is also very dangerous, anyone who has seen the movie 'Fight Club' would recall the scene where Tyler Durden puts a pile of this material onto the protagonist's hands. When it comes into contact with water it reacts with a very strong exothermic reaction (it generates heat), and for this reason the NaOH should always be added to water and not the other way around as this ensures that the heat is absorbed by the water, rather than the heat inducing the hydroxide to react violently with the humidity in the air, and it can in fact explode, spraying highly reactive material everywhere, and when this gets on the skin or in the eyes, it burns severely.
It is recommended when working with sodium hydroxide to wear protective goggles in case it splashes in the face, it can destroy your vision .

I have written this guide to specifically cover the process of extracting alkaloids from the Acacia Obtusifolia tree's bark, which is the most consistently yielding of the acacia species with regards to it's yield of psychedelic tryptamines, primarily N,N Dimethyltryptamine. It is equally applicable to mimosa hostilis, and is likely to be useful for any other DMT source contained in the bark of a plant (eg, desmanthus illinoensis). Chlorophyll laden sources, such as phalaris and psychotria viridis et al have not been studied by the author, however at some point in the future the special considerations for these leaf materials will be added.
One thing that I have learned in recent months about the process of extracting alkaloids is that the long periods of time suggested in older guides are unnecessary, this suspicion started to come to me when I witnessed the acid/base extraction of alkaloids from an alkaloid synthesis and saw that the alkaloids can in fact cross phases in a matter of minutes, not hours or days.
Taking care to ensure certain pH levels are used also eases and improves the process, specifically in the acid phase the pH is better if it is about 4, and in the extraction less emulsion problems occur when working with a pH above 12.5 (sodium hydroxide does not raise the pH above 13.5 when diluted 5g/100ml, so the concern about 'pH spikes' is unnecessary so long as the base is diluted). When washing and extracting, use gentle agitation rather than violent, swirl, stir or turn it end over end gentlyrather than shaking it. Water washing is less of a problem in this respect, usually by that stage the majority of emulsion causing chemicals have been removed.
Something else which I have heard from others, which I have now verified, is the value of doing washes. Previously washing was little mentioned, and only the wash of the acidic extract was suggested (and again, a much longer than necessary time stated), when in fact the best results seem to be from doing a non polar wash of the acidic extract, and using a fairly low pH (like 8-9) and no salt, for washing the non polar extract (the best proceedure seems to be using sodium bicarbonate as it reacts with sodium hydroxide to produce sodium carbonate, which more readly comes free of the nonpolar fraction). Washes ensure the resulting product is as free from contaminants of a non-alkaloidal nature as possible, in particular residuals of the base being used. Again, gentle agitation is completely sufficient for extractions and washes, and in the case of water washes, violent agitation will not allieviate suspended droplets of the base, the bubbles of the wash water, being alkaline, will wash some out, but will also leave the suspended bubbles of base in the nonpolar solvent, though by this stage in the process it doesn't matter as much as it should be quite clean already.
Finally, the best methods for recrystallising the product seem to be coalescing for me as well, I will talk about this at the end, the purpose is not, properly speaking to make pretty rocks, though if large crystals are produced they have a longer shelf life due to lesser surface area per volume, but instead, the purpose of recrystallising is to eliminate the contaminants in the solvent commonly used (naptha), as well as reducing other contaminants. This requires slow cooling or progressive cool/warm steps.
This guide will not attempt to cover the extraction processes for other plant materials, however it is intended to be comprehensive and to the point, and should apply more or less to other materials.
I will also focus on the equipment which will ensure the best results with the least outlay without any compromise of efficacy of the process.

This guide is specifically targeted at the acacia obtusifolia, I cannot really enlarge upon other information already available through libraries and on the internet, but I intend to replace this section with a comprehensive guide to finding them based on a series of expeditions to likely locations and lots of photographs, and, of utmost importance, in plain english.
One of the problems with the botanical information regarding these plants is that they never go into much detail about the bark structures. When walking through a well developed forest, quite often the tree is so far above you that you can't see a thing of what they describe in the botanical description. As soon as possible, a photographic expedition will be made to bring back good photographs of the plant in it's mature natural state. The full extent of the obtusifolia's habitat is not fully known, it may well be more common than is currently thought.
The guide should be applicable to other sources of DMT, as the method described is very thorough.
go to table of contents
Other, more advanced chemistry equipment can be used for this process, however my aim is to only talk about what I believe to be the minimum standard to ensure the best possible results.
go to table of contents
The bark must be prepared for extraction, a simple but effective method that can be used is to simply pull strips of fibres off using fingernails (or assisted with a pocket knife) so that thin pieces are removed - this must be done when it is still fresh. The bark can be cut up into small pieces and put through a blender or coffee grinder, this is best done when dry, though cutting it up when dry can be difficult, it would be best done when still fresh (it is best to ensure cutting goes from the inside of the bark to the outside because the inner fibres are long and resistant to being cut). If bulk quantities are being worked with (like 10kg or more) a mulcher can be very effective. A small garden shredder is very helpful in any case, and for anyone intending to powderise the material, it needs to be broken into small pieces before putting into a blender.
The more the bark is munched up the faster and more thorough first two steps are.
go to table of contents
This step uses an acid to make the tryptamine alkaloids soluble in water - the acids ionically bond weakly to the amine tail of the tryptamines and render them soluble in water like any other salt.
This permits other elements in the solution which are less soluble in water and sparingly soluble in water to be removed in the next step.
|Prepare a solution of water with the pH adjusted to 3-4 with the acid you are using.|
|Add to the plant material to the solution, either soak (a couple of hours for powdered material, overnight or longer for less finely shredded material) or simmer for 1 hour.|
|Pour off the liquid and repeat two more times with more acidified water.|
|Combine the extractions and reduce on gentle heat to a workable quantity (about 1L)|
go to table of contents
This step uses the fact that the alkaloids are now well dissolved in water to permit the use of an aromatic solvent (which would readily dissolve the alkaloids in freebase form but not as the salt) to thoroughly strip anything from the solution which will contaminate the product at the end of the process.
There is significant likelihood that the bark contains small amounts of histamines, which will be removed by this as well; in susceptible persons, histamines will cause the throat to constrict and make breathing difficult when smoking the product, which is an unpleasant side effect that is best avoided.
Aromatic solvents are suggested in this step because they dissolve more than any other Non polar solvent, and thus clean the product more than ether, chlorinated solvents or naptha/shellite.
|Pour the acidic extract into the separating container (separatory funnel or jar).||
|About 100ml of the aromatic solvent (toluene or xylene, or at a pinch, 200ml of naptha) is added and the jar is gently agitated (swirling, stirring, end-over-end)||
Aromatic solvents are used in this step because they have high solvation power, and will remove anything that might contaminate the final product.
Adjust the volumes of solvent upwards in the case of lesser solvents (such as naptha) to ensure it pulls as much of the gak as possible, also use more solvents if one is working with a larger quantity of material
|Separate the aqueous phase from the aromatic solvent phase.||
Repeat the wash with the aromatic solvent two more times.
The reason for doing more non polar washes is that the primary contaminants in the product is usually from not doing sufficient washes at this stage
Do a final wash using the solvent that will be used for extraction to remove any excess aromatics suspended in the solution.
This is done to eliminate the majority of the high boiling aromatic solvent from the solution so when it is extracted the high boiling component of the solvent is reduced. If there is materials that boil at a significantly higher temperature than that of the DMT (i.e. much more than 120°C) the DMT will not crystallise or dry properly, as it will boil before the solvent it is mixed with. This is known as 'oiling out' and is best avoided if possible.

In this step the pH of the now washed extract solution is raised to 13, which will drive the alkaloids out of the water by binding up the acids that caused the alkaloids to be water soluble.
|Mix up a solution of the base - for sodium hydroxide, 5 teaspoons to 250ml is sufficiently dilute.||
If one is concerned about pH spikes from introducing a solution this concentrated, twice as much water can be used. The pH of the solution made via the instructions to the left is around 13.5 or so, and really it isn't too strong. The main thing is adding it slowly while stirring.
|Add the alkaline solution slowly to the acidic extract, stir well while adding the base.||
There are many ways to do this, some people use a baster to transfer the solution, and use it to stir and pump the solution around, it can also be added slowly by pouring it in while stirring with a skewer.
I don't recommend basifying in one container and then transferring to another. The DMT can stick to a lot of plastic and glass surfaces, and ideally one wants to get as much of it as possible.
go to table of contents
Making the pH to 13 drives the tryptamines back into freebase form, in which they are insoluble in water. They are, however soluble in Non polar solvents, such as the ones described as suitable extraction solvents (ethyl ether, DCM and shellite/naptha). This property permits the separation of the freebase from the basified aqueous extract solution. Using a pH this high also eliminates emulsions.
|Add a quantity (100ml is a good amount for an extraction with an expected yield under 3g) of the extraction solvent to the basified solution.||
The amount of solvent to use depends a lot on how much you expect to get from the plant material.
As a rule of thumb, 100ml of naptha/shellite will dissolve about 1g of DMT, less is needed for dichloromethane and ether, though the amounts must be kept practical for the separation method being used.
Also note that using an excess of solvent may result in more being extracted than desired. This is particularly the case with naptha.
|Close the container gently agitate, periodically vent to release pressure||
Some guides recommend heating the extraction solution to increase how much it draws across when doing this, I must stress that this will dramatically increase the amount of pressure that will be generated by the agitation, having almost lost my vision from not venting a jar of hot shellite and having the jar pop and spray everywhere, I don't recommend heating the solution at all.
Some guides say 'keep the base cool and the solvent warm' - this is not physically possible, the heat in the total solution will very rapidly equalise, especially if it is shaken vigorously.
|Separate the nonpolar solvent from the basified solution.||
Because the pH is high, at around 13, and because the solution has been thoroughly washed, it will not form stubborn emulsions, the differentiation of the layers usually is almost perfect within 5 minutes.
It is not neccessary to wait long - 5 minutes of gentle agitation and 10 minutes of settling is usually long enough for each pass
go to table of contents
This step is done to eliminate any residual polar soluble contaminants present in the Non polar extraction. The main concern is the base itself (which burns hot and makes the product harsh), though there is also problems involving contamination from the aqueous fraction also, plant substances etc.
Generally speaking the stuff washed in this step will not prevent crystallisation if left in, but it should not be left in because it is just yucky.
Add an excess of water adjusted to a pH of at least 8.5 to the non polar extract solution.
Gentle agitation is essential to ensure that no microbubbles of alkaline wash water remain in the nonpolar extract solution. If violent agitation is used, one should use plain tap water, but I don't recommend violent agitation, basically it is unneccessary
Remove the water from the nonpolar extract, and repeat this wash two more times.
|Repeating the wash three times will ensure that none of the base or other polar soluble undesirables remain in the solution. This step is critical for removing residual hydroxides and salts of the acid and base being used. If this step is not done properly, the hydroxides will react with the freebase and destroy them, not to mention burning the throat.|
go to table of contents
Next, put the combined Non polar extracts onto a drying dish, something that will permit the easy scraping of the materials.
Using an electric fan to blow the drying dish vigorously is a good idea, it dramatically increases the rate at which the solvent evaporates off.
If the proper equipment were available, a vacuum desiccators would be even faster, and would permit recovery of the solvent, though this is not accessible to most people who wish to do this process. The shellite evaporates very quickly anyway, and ether and DCM are even faster.
Although it probably helps with getting all of the extract out of the dish, it is not absolutely necessary to bring it fully to crystallisation at this stage. This will take at least 12 hours to fully happen under a fan. The extract is easier to remove from the drying dish if it is fully dry as it has a much harder consistency and comes free of the glass much more readily.
go to table of contents
This step is done to refine the product further, and indeed can fully purify the extract to translucent crystals. The longer this stage is done, the larger the crystals can become.
When recrystallising, the idea is to use a solvent which dissolves undesirable elements better than the desirable element, hence with study, the best possible solvent or mixture of solvents can be developed to clean the product most effectively.
This step eliminates contaminants in the product which will make it harder to smoke.
Heat the recrystallisation solvent until it starts to boil by sitting in a container over water heated in a jug.
|A good container to put the recrystallisation solvent in is one which has a dropper in it, as you can simply let it sit in the water until it gets to the same temperature as the water, and then you can immediately drop the solvent onto the freebase.|
Be careful here not to let the freebase get so hot that it boils, as this will cause a loss of product
|Slowly add the hot solvent to the warmed recrystallisation container, stirring and agitating until all of the product is *just* dissolved.||The idea here is that the minimum amount of solvent, at the highest temperature possible (at which it will dissolve the most possible product for the volume), which, when cooled will not dissolve the product very well at all, and thus it will precipitate as crystals.|
Seal the recrystallisation container.
A jar can be used for recrystallisation - when the product crystallises hard as it does in this process, it can be scraped out using a scalpel or a piece of wire.
If using a beaker or bowl, a double layer of plastic wrap is recommended, and fixed in place using a rubber band.
Sealing the container simply prevents the crystallisation of water when the container is put in the freezer.
Let the container cool to room temperature.
Alternate between the fridge and outside the fridge every hour or so for as long as you like.
The colder temperature causes crystals to precipitate, and then warming them again dissolves the smaller crystals more rapidly than the larger crystals.
When done for long enough, this favours the formation of large homogenous (containing only one substance) crystals. In the case of acacia obtusifolia, there is only DMT and NMT. The NMT forms an amorphous yellow resin, and with the correct choice of recrystallisation solvent, can be selectively removed, leaving behind only the DMT, which is a translucent waxy crystalline substance.
The DMT, in any case, (and I think this applies to 5 methoxy DMT) is a clear crystal, the yellow or brown or red colour common in extracts is not from the DMT.
It improves the resulting size of the crystals if the initial room temperature/refrigerator stage is done for a lot longer, this causes the crystal cores to trap less contaminants.
Then alternate between the freezer and the fridge for another period of time.
While still at freezer temperature, discard the solvent (it has very little in it of value).
Because the extract was just dissolved at close to it's boiling point, at the temperature in a freezer there is a very insignificant amount of the desirable alkaloids remaining in solution. With the right choice of solvent, the DMT can be preferentially precipitated and thus isolated from the other components in the extract.
|Repeat up to two more times||
If done more times, the extract is much cleaner.
|Dry the final recrystallisation.||
When the extract is very pure, the product will be very easy to remove from the container. A scalpel is a good device for this, one with a curved blade.

I have written this extraction procedure in the hope that others who find the lack of clarity and good chemistry information in most guides offputting, also this guide exposes a number of myths regarding times required for processes, in particular the Non polar extraction. The product resulting from following this guide, assuming one begins with a good source, should be just about as pure as the product can be made. Also, if a neophyte follows this process, and they have started with good material (good material is equally important as the right technique, you can't get gold out of you put garbage in), is guaranteed to get a good result.
I will be revising this process until it becomes clear that it covers the topic in a thorough and concise way, it is my hope that this document will ease the transition from neophyte to journeyman that can be extremely frustrating and drawn out. Accurate information will ensure that so long as the directions are followed, good results will come out at the end.
Reports of using this guide will be appended to the end, I encourage anyone who has had success with this technique to send me their reports so I can add this to this document to demonstrate the efficacy of the technique, and to encourage neophytes to keep trying if they do not do as well as they expected.
One final comment, most people will not get as much as they hope for out of
extractions. Over a process of a number of extractions one gets a better idea
of how much to expect, the visual appearance of quantities of freebase of various
weights will take a while to know, as will the amounts of plant material that
produces it, and in some cases, the right times and ways to collect the material
will also influence the results. Do not be disheartened if yields are lower
than you expect, only experience will teach you how much to expect in practice.

Mimosa Hostilis Extraction (13 April 2003)
Materials; A few 500ml flasks/beakers, a jar, separatory funnels, vacuum
hand pump, glass funnels,
I started by boiling 325ml of distilled water, then took it out of the pan and into a beaker where I acidified to a PH of about 3 or 4 using muriatic acid.
Then I poured this acidic water in a jar containing 88.4 grams of finely powdered mimosa hostilis root bark. Since I used hydrochloric acid I decided not to add all three acidic water extracts together and reduce volume because I didn't want to concentrate the acid.
So what I did was each of the 3 extracts on there own. After putting the acidic water with the root bark I waited 1 hour and poured the liquid/root bark into a cheese cloth on a beaker, and squeezed all of the water out. I then took the dry root bark and put it back in the jar with the same amount of acidic hot water as the first time.
And while waiting another hour for that to finish up I filtered the liquid from the first extract into a funnel with cotton and a vacuum pump connected to the flask.
Then I defatted by putting 80ml of xylene and throwing away the xylene/emulsion. I defatted 2 more times with naptha(80ml).
Then I basified with NaOH, when it was about half way threw I added some naptha and kept basifying until it turned a slippery black type colour. Then I separated the naptha with the emulsion and added 80ml of warm naptha. I separated that naptha/emulsion and added another 80ml of warm naptha. Again I separated and kept the naptha/emulsion.
Now I took the naptha/emulsion and added some PH 8 distilled water and threw away the water. This got rid of most of the emulsion, I put the rest in a graduated cylinder to further separate. I washed the naptha 2 more times with PH 8 dH2O.
I evaporated the naptha via fan and dish to reveal .4grams (400mg)of white fluffy crystals. By this time the second soak of root bark was ready to be further extracted so I put that through a cheese cloth and cotton funnel and then put more acidic water with the root bark.
I defatted this time with only naptha 3 times. Basified and extracted and washed just as before. I evaporated this to find .22grams of crystals. I extracted the last of the acidified water by filtering, defatting, basifying, added naptha, washed naptha and evaporated just as before to get .06grams of crystals.
I did this whole extraction in under a day, and my yield tells me I really don't have to wait as long as some teks say. My total yield was .68grams of spice from 86.4g of mimosa root bark. That's .4grams the first one, .22 the second and .06 the third one.
As you can see the last extract is low but not completely insignificant. If I were doing an extraction with a different acid like say acetic(vinegar) acid I would have combined my extracts and boiled down to about half or 1/4th it's original volume, but since I used HCl I decided it would be better to do each separately.

Defatting the acidic extract (see the colour in the naptha layer?)
Basifying (notice how the base immediately makes the solution turn opaque pinkish)
when the solution is fully pink, the pH is between 10 and 12,
Naptha added to basified extract - as it turns black (seen here at the bottom of the flask) the pH is over 12 - this is how high it needs to be for proper extraction
First extraction run (see the pink stuff - that's emulsion, wait until it settles and the margin between the layers is mirror-like)
Water washing (note the dark colour in the lower layer - this is why you water wash) (also, for this first step, use sodium bicarbonate as this will eliminate the residual sodium hydroxide, transforming it into sodium carbonate)
Water washing - see how it gets lighter
Water washing - never stop water washing until there is absolutely no colour in the water being used to wash with
Crystals scraped together (note how clean looking they are - this is achieved through proper defatting)
