Introduction πŸ™

HIELO stands for Honey In Ethyl-acetate Laizily Over-the-counter and is inspired by the techniqies developed in CIELO[1]. DMT from MHRB is precipitated in ethyl acetate as what is believed to be relatively pure mono-DMT citrate hydrate with a honey-like consistency†. The honey is dissolved in 50/50 PG/VG to make a DMT salt e-juice (see Fig. 1). This technique (TEK) is specialized for MHRB, is relatively simple, and avoids harsh chemicals.

Thanks to everyone who contributed to this process: _Trip_, Loveall, and others.

†A confirmation analysis has not been done at this time, and purity is a best guess based on appearance and subjective effects . Also, the he hydration number (number of water molecules per molecule of mono-DMT citrate) is currently unkown.

Safety ⛑️

Review ethyl acetate[2] and citric acid[3] safety information. Verify solvent MSDS, plastic compatibility, and clean evaporation.

This TEK is food safe if food grade materials are used.

The final product is a dmt salt e-juice. However, other plant material could be present and/or some of the extraction ingredients could be in the product depending on technique or possible process errors. The long term health effects of vaping this product are unknown and therefore carry a risk. It is up to each sovereign individual how to proceed.

Following this advice does not guarantee safety. It is up to each adult individual to make their own personal decisions.



  • 150g water
  • 25g Ca(OH)2 (lime)
  • 100g finely ground MHRB†
  • 1qt ethyl acetate (sometimes sold as "MEK substitute")††
  • 5g of citric acid (~1 tsp)
  • Washing soda (Na2CO3) 10% water for solvent reuse

† Ingredients can be scaled down to 5g of powder to perform a TEK test run. This is encouraged for beginners to get a feel for the process before commiting more material.

†† Depending on pull technique using two quarts of ethyl acetate may yield a little more DMT (up to ~+10%). See extraction section for more details.

Detailed Process πŸ“œ

Paste 🟀

Make milky water in a french press, quart jar, or mixing bowl by mixing lime with the water. Add the MHRB powder, stirring thoroughly to ensure the bark is well incorporated. Goal is to get a wet stiff consistency (Fig. 2). If needed gradually add more water as needed.

Extract πŸ§‘πŸΎβ€πŸ”¬

If available, the paste should be in a french press. The french press will make it easy to decant the ethyl acetate. Optionally the paste can be in a a quart jar, but it's not as easy to decant the ethyl acetate. It is possible to have the paste in a mixing bowl, but decanting may be cumbersome.

Cover paste ethyl acetate (~200g) and stir for about 10 minutes. Do not to stir too aggressively as that may cause plant material to absorb excess solvent. A good paste becomes sandy and slightly sticky during extraction and is very easy to handle, but other textures also work. After stirring, rest for two minutes, and decant into a quart jar filtering through a paper coffee filter (do NOT skip or substitute the coffee filter). If using a french press (preferred), only squeeze lightly to accelerate decanting (keeping plastic parts away from the solvent). Squeezing too aggressively can release unwanted water into the extract which will need to be separated in the next step.

If the paste absorbs all or most of the ethyl acetate during the first pull, that's fine. Just add more ethyl acetate, stir, rest, and decant as explained above. Do NOT add water or aggressively manipulate the paste in an attempt to force out the ethyl acetate. Some solvent absorption during the first pull is common.

Repeat the extraction with ~125g of ethyl acetate until the extraction jar is full (5-6 total pulls). A small yield boost can be done by optionally doing more pulls into a second jar. This second jar is also a good check on the effectiveness of the pulls in the main jar the first time this TEK is performed. Poor technique will give a larger yield boost in the second jar, <10% boost is considered good.

Rest extract for 24 hours in a refrigerator. Water solubility in ethyl acetate decreases with temperarure, so this cold resting period is effective at removing excess water. Some cloudiness is OK when the EA is cold. If a lot water forms (more than a few droplets forming a visible layer), the paste was either too wet, or the french press squeezing was too aggressive, or the genlte stirring was done with poor technique. On the other extreme, chemichally drying (e.g. with anhydrous K2CO3) is not desirable because some water is needed to form the hydroscopic DMT salt honey.

Weigh an empty jar (0.1g resolution is needed), decant ethyl acetate into it through a coffee filter, cover, and bring to room temperature. Extract will be clear and ready for the next step. The extract needs to be clear, particle free, and without water droplets for the salting process to happen reliably (see Fig. 3).

Fig. 3: Ethyl acetate extract. Color may vary, but extract must be clear and free of debris and water drops. It is very important to give the extract time to rest so water dropplets have time to settle out and be decanted if present.

Precipitate Honey 🍯

Stir ~5 grams (~1 teaspoon) of citric acid powder granules into extract until citric acid dissolves. This should only take a few minutes. Extract should cloud as the citric acid reacts with DMT free base to form mono-DMT citrate which drops out of solution. Leave extract undisturbed. Mono-DMT citrate woth a honey-like consistency should begin to appear after a few hours, and may take a few days to completely crash out (waiting 3 days is recommended). See Fig. 4.

Make E-juice πŸ’‰

Decant solvent leaving honey behind. Rinse twice with ~ 50ml of fresh ehtyl acetate (this may temporarily dehydrate some of the honey and give it a white color which goes back to honey color once exposed to atmosphere). Allow to air dry until ethyl acetate smell is not present and jar weight stops changing on a 0.1mg scale (a few hours at least, one day is reccomended).

Measure jar weight and calculate honey weight (~45% DMT strenght estimated). Add 1.3x of a 50/50 PG/VG solution to the jar and dissolve over a hot water bath to make a dmt salt e-juice of ~20% strenght. There is no analytical data to back up these claims and they could be incorrect.

For example from a typical extraction of 100g of MHRB[4]:

  • Empty quart jar weight 388.2g
  • Quart jar with DMT citrate honey: 392.6g
  • Honey weight 4.6g (equivalent to 2.1g of DMT free base)
  • Add 6.0g of 50/50 PG/VG
  • Final e-juice product weights 10.6g and contains 2.1g of DMT (~20% strenght) in citrate salt form

Reuse πŸ’š

Reusing solvents is encouraged[5] at the DMT nexus.

Wash spent extract with ~10% sodium carbonate water solution. About 1/3 of the solvent volume is enough for neutralization. Shake vigorously (emulsions do not form). CO2 bubbles may be visible during citric acid neutralization. Keep an eye on any bubbles and release any pressure buildup regularly. Neutralization can be optionally verified with pH paper. Rest washed solution until clear (up to a day or more).

Remove the water layer with a pipette or separatory funnel and filter. Optionally, freeze the solvent and remove the ice slush that forms with a thin mesh metal strainer.


Vaping Info πŸ’¨

When vaping an e-juice an aerosol of PG/VG dropplets is produced[6]. The dissolved DMT salt is delivered to the lungs by these particles where it is absorbed. The word "vaping" is arguably missnomer, the dmt salt is not being vaporized, instead the DMT salt solution is being aerosolized and carried into the lungs dissolved in small liquid droplets. In other words, DMT free base it not being vaporized into a hot alkaline gas as is done with traditional flame or newer electronic resistance heat methods (health stone, e-mesh, quartz crucible, etc).

There are many ways to vape e-juice. An example method is presented here for beginers. This method is not superior to others out there, it is simply an illustrative working example: *Geekvape Wenax H1 with an 1.4 ohm coil at the high power setting. This device uses reusable and disposable pods to store the e-juice that do not leak. With a 1000mAh battery it has plenty of power to vape a full pod with 2.5ml of e-juice capacity. With 20% stenght this is about 500mg of DMT or about 35 good doses. Always leave at least a few drops of e-juice in the pod beofre refilling to avoid unhealthy bad tasting dry hits and a burned coil.

In general, a 20% e-juice dmt salt is not very convenient for breakthrough due to the large volume of vaping required. However, it is ideal in combination with oral or sublingual harmalas for longer smooth vaporhuasca sessions. A working example is to sublingually take 40mg of 1:1 Harmine:THH about 25 minutes before vaping. Relax and enjoy.

Starting From DMT Freebase 🌟

If instead of MHRB one is starting with DMT free base, simply mix the following ratios by weight over a heath bath:

  • 1 part DMT FB (very clean for electronic juice devices)
  • 0.35 parts citric acid
  • 2 parts PG
  • 0.6 parts VG

The resulting e-juice is about 25% DMT FB. PG/VG ammount and ratios can be adjusted for different preferences.
