CIELO

Introduction πŸ™

CIELO stands for Crystals In Ethyl-acetate Leisurely Over-the-counter.


In this technique (TEK), cold cactus alkaline paste (Fig. 2) is extracted with chilled ethyl acetate (Fig. 3). Mescaline citrate is precipitated with citric acid (Fig. 4) and collected (Fig. 5).

Safety ⛑️

Review ethyl acetate[1], and citric acid[2] safety information. Verify solvent MSDS, plastic compatibility, and clean evaporation.


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

Materials πŸ›’

  • French press (or similar ensemble)
  • 300g water
  • 25 of lime
  • 100g dry cactus powder (outer skin or whole plant)†
  • 100g anhydrous CaCl2 (ice melt)
  • 1qt ethyl acetate (MEK substitute)
  • Coffee filters, support basket, and funnel
  • Quart jar
  • 1/2 tsp Citric acid
  • Washing soda (for solvent reclaim)
  • Activated carbon (for solvent reclaim)


†If starting with fresh cacti, store the dark for 3 months, slice into ~half inch disks, dry in oven at lowest heat setting, and grind to a fine powder (keeping spines is ok)[3].

Process πŸ“œ

Paste 🌡

Mix water, lime, and cactus powder. Microwave stirring between short runs (watching to avoid a boil over) until 100g of water is evaporated (~20 minutes of irradiation at 1000W). Stir in 100g of CaCl2 to a fluffy consistency and place in freezer (~0F) overnight (Fig. 2).


Quick and dirty option: Simply mix ice water lime and cactus powder. This cold paste will release more plant matter (see Fig. 3) and is not recommended for whole cactus powder or solvent reuse.

Extract πŸ‘¨πŸΎβ€πŸ”¬

Cover paste with freezer chilled ethyl acetate (~0F), mix for 60s, and filter into quart jar. Repeat until quart jar is full (~5x).


Inspect extract for droplets or particles. If present, remove them. Extract needs to be clean (see Fig. 3).

Crystalize ✨

Drop (do not stir) citric acid into extract. Clouds form quickly, slowly followed by mescaline citrate crystals (Fig. 4). Allow crystalization to complete undisturbed (~12 hours).


Note: If using whole cactus more citric acid may be needed to induce crystallization (up to 1 Tbsp).

Collect πŸ’–

Swirl crystalized extract to knock off crystals from walls and dissolve any remaining citric acid granules. Catch floating crystals in a coffee filter. Repeat with a small amount (~1oz) of fresh room temperature ethyl acetate until all crystals are in the filter and off color is washed (~2-3x). Dry and collect from filter (Fig. 5).


Yield depends on the cactus and is usually between 0.2% to 2% with ~1% being common[4].

Mass spectrometry (MS) results from solaris analytical[5] indicate the product is very clean mescaline (Fig. 6).

Reclaim Solvent πŸ’š

Reusing solvents is encouraged[6] at the DMT nexus.


Wash spent extract from the microwaved paste with sodium carbonate saturated water shaking vigorously (emulsions do not form). Filter any excess calcium carbonate and remove water layer. Freeze and filter out ice crystals. If a yellow color develops after multiple reuses it can be removed resting over activated carbon for several days.

Appendix: Development Notes πŸ”¬

Paste 🌡

Microwave assisted saponification[7]breaks down polar compounds such as chlorophyll. CaCl2 enables extraction with at (~0F) without the water freezing solid. Both saponification name cold temperatures result give a clean extract and robust process.


Sodium bases and salts (Sodium carbonate, sodium hydroxide, and sodium chloride) where tested but made the paste congeal and lose yields. Therefore, calcium is recommended.

Extract πŸ‘¨πŸΎβ€πŸ”¬

Longer/warmer pulls resulted in darker extract, smaller crystals, solvent paste absorption, congealing of paste, and no yield benefit.


Chemically drying the extract had no benefits.


An additional long room temperature pull on the TEK's spent paste only yielded 4mg of very small crystals, indicating the chilled pulls are efficient.

Crystalize ✨

During crystallization, every 233mg of citric acid (H3Cit) react with free base mescaline (Mes) to form to 1g of mescaline citrate (or slightly more if a hydrate is precipitating):


3Mes(↑) + H3Cit(↑) β‡’ 3(MesH)Cit(↓)


Excess citric acid shifts the precipitation reaction to the right (Le Chatelier's principle), helping overcome water and plant material. There is a lot room for excess citric acid in solution since its solubility is 50mg/g in ethyl acetate. The TEK guidelines range from 1.5mg/ml to 20mg/ml, but since cacti and pull techniques can vary, users may find other values work better for their specific situation (in one specific example with whole cactus powder 20mg/g was used [8]).


Several factors can make crystals smaller: Reusing ethyl acetate, longer/warmer pulls, higher citric acid concentration, mechanical agitation, and other potential variables. Small crystals can look like a fine powder. Potency does not seem affected by the crystallization appearance, and a powdery precipitate is not a problem unless it becomes difficult to decant/filter.


After the initial crystallization, adding more citric acid and/or moving the extract to the refrigerator did not result in any more precipitation. Moving the extract to the freezer produced ice crystals.


Other dry organic acids could work. Fumaric, Malic, Tartaric, Ascorbic, Succinic, etc can be tested in future investigations.

Collect πŸ’–

Washing crystals in a filter appears to wick away plant colors and superior to decanting. Unlike the pulls, warmer ethyl acetate is preferred to wash off plant matter.


The quart jar wash should be done immediately. If any straggler crystals dry in the jar they may stick to the wall. To recover from such a situation, dissolve stuck crystals in hot water, dry in a shallow dish, and scrape.
