What Is THCA Crystalline And How Is It Made?

Never have we witnessed such a level of purity in an extract. The team over at Guild Extracts might’ve been the first, but what this represents is bigger than them. Welcome to the world of 99.9% pure THCA!


Created by the team over at Guild Extracts, this is an extract composed of 99.997% THCA. Most extracts today will have around 50-80% purity. As the first team to successfully do this, it’s claimed to be the strongest hash in the world. And with a 0.003% margin, it will be hard to improve upon. It has gained extreme popularity due to its uniqueness and purity. And this can be observed with its prices, reaching as high as €170 a gram.

When processed, pure THCA crystallises. Its visual similarities to drugs like cocaine make a lot of people question it. But the true breakthrough with this extract is beyond the recreational market. THCA, when decarboxylated, loses its acidic atom, leaving behind the pure THC. This happens when you light-up or pressure the cannabinoid. This purified cannabinoid came to change the game for all those in need of potent, medical THC.


When dealing with such a pure substance, precision is one of the main advantages. Never before could a patient be so sure of his/her THC intake. When dealing with flower and even other extracts, it’s extremely hard to know the exact THC percentage it contains. The error margins are relatively large. With THCA crystalline, the patient can continuously assess results based on the dosage, knowing that it will always be consistent.

Edible companies will now have access to an extract that will allow for more precise dosing of products. This is an extract that will also act extremely fast, which is a great advantage, especially considering the time an edible can take to hit. This can be crucial for certain conditions treatable with THC.

Another great advantage is that, when ingested without being decarboxylated, THCA will have no psychoactive effects, but will still present various medical applications. This is great news for patients in need of THC, but who don’t enjoy the high it gives. When there is no heat or pressure applied, THCA can be placed in a drink or meal with no alteration in mental functioning.


When dealing strictly with THC (or THCA), there will be things one must sacrifice. This extract has no terpenes, so it won’t have pungent aromas or flavours. Some consumers even report it to taste like “snowflakes”, which in turn tastes like water, which is tasteless. You get the point. There will be no possible alterations to the product. It doesn’t matter what the strain is or how it was grown, 99% THCA will always be the same. So, you’ll either enjoy the high or you won’t. You’ll also be sacrificing the “entourage effect” that other cannabinoids have on THC. You won’t be experiencing cannabis, you’ll just be experiencing one cannabinoid.

But once you try it, you might be surprised. The high is described as extremely clear, fresh, and energetic. It’s almost a little too clear and fresh for some who describe it as too medical. It might be possible that consumers become so high that they can’t even recognise it for what it is. But the high is surely there; with almost double the purity most of us have experienced, it might just be a high we can’t yet comprehend. But in a way, it’s good that it’s “too medical” because that’s exactly what it should be used for. By using a substance this pure for recreational purposes, it might be hard going back to smoking joints or bowls – the high will be nowhere close.


If you have no basic information on how extracts are made, this might seem a little overwhelming, but the idea behind the process is fairly easy to understand. This all starts with your usual cannabis extract derived from cannabis plant material. But to make the process faster, an already isolated substance is often used.

This extract is then mixed with hexane and acetic acid. These are two chemicals that, together, will help further separate the plant material form the THC. This happens by dissolving the plant matter, but keeping the good stuff untouched. This solution is then placed through a filter so that more plant matter can be removed. The remaining liquid will be placed in a rotary evaporator.

This machine will use different values of pressure, heat, and motion to further separate elements in the solution. After this process, the resulting liquid is called Δ9 tetrahydrocannabinolic acid. But this is still far from what we’re looking for. There will still be impure elements, so chromatography will help remove these. Sephadex-LH20, dichloromethane, and chloroform are added to our tetrahydrocannabinolic acid.

To further purify it, the chemists will place the crystals back into the rotary evaporator. These are then mixed with methanol to separate even more impurities. This solution then goes through a filter to remove these impurities and back into the rotary evaporator to remove the methanol. To end the process, this will once again be mixed with a dissolvent to purify the mixture to the 99.997% it’s famous for. This is finally placed in the evaporator once again to remove the harmful solvent. And there you have it; this is what creates THCA crystalline.

How to make THCA crystals: Guide to THCA extraction process

THCA is getting more populair everyday, especially for it’s medicinal purposes. Altough it’s still very hard to find in most areas around the world. Many people interested in it have no possibility to get it, so the question: how to extract/make THCA yourself is one asked many times. To really understand the process you first need to know what THCA exactly is!

THCA crystals are probably one of the most pure extracts in the world and discovered by Guild Extracts. The crazy thing is that pure THCA doesn’t have any psychoactive effects and won’t contain any terpenes (So it’s tasteless and odorless). To make it psychoactive, it has to turn into the substance THC which only can be done by a process called: Decarboxylation. This happens when you heat or give pressure to the cannabinoid.

THCA can only be found on fresh plant material and the extract will always be exactly the same (it’s just one pure cannabinoid you consume, it’s always the same in strength, taste and effect regardless the strain or plant it comes from). When you light it up, it will turn into THC and make you “high” but if consumed in another way like ingesting it, the decarboxylation proces didn’t took place and you only benefit from it’s medicinal effects. Perfect for patients who are in the need of THC but don’t like the mental high it gives.

The extraction process of THCA using solvents

Now you are probably interested to get some THCA yourself and try out this amazing stuff, right? Well the process of making THCA crystals isn’t easy and requires some equipment and knowledge. The way it’s made and the fact that it’s very concentrated makes it a pretty expensive extract so making it yourself could be paying off!

Without any experience of extracting, this process might look a bit overwhelming and difficult. But if you follow the steps closely, it’s possible to do! (with right equipment). Most of the times it already starts with a cannabis extract like BHO or full melt hash. This makes the process faster.

  • Extracting simply means to take one substance out of to other. So to seperate the left over plant material from the THC(A), you’ll need to put the extract in 2 chemicals called: hexane and acetic acid. This will dissolve a large part of the plant material. After that, the mixture will go trough some filter wich helps the dissolving process.
  • Now you are left with quite some liquid that should be placed in a rotary evaporator. This evaporator will use different kind of pressure, heat and motion to keep seperating and dissolving different element in your mixutre. After this, there will be a left over mixture called: Delta(9) Tetrahydrocannabinolic acid.
  • We might get closer to pure THCA but we’re not there yet, still there are some impurities and elements we need to get rid off. This will be done with a process we call: Chromatography! Chromatography is another way of seperating different elements from each other and used by when measuring THC level in cannabis. Find out more about this process!
  • In the next step we will add dichloromethane, chloroform and Sephadex-LH20 to our tetrahydrocannabinloc acid and create a new kind of crystalized mixture.
  • This mixture will be put back in the rotary evaporator and mixed with quite some methanol which purifies it even more. Then it will go trough filter again and put back in the rotary evaporator to the methonal from your THCA extract.
  • Finally, this last step is being repeated once again using a dissolvent to purify it to 99.997%. Then this last mixture will be placed in the rotary evaporator for the last time (to remove the harmfull solvent). Now you are left with true THCA crystalline!

This extraction method isn’t the easiest one and requires some knowledge, experience and equipment. But after getting to know other extracts and the way their made, it’s pretty easy to follow and do-able at home. But remember: you are working with chemicals and heated equipment so always be carefull and safety first!
