Once you have the CBD content, it’s time to choose a carrier oil. Depending on your preferences, you can select virtually any type of oil, but most people use either coconut oil, olive oil, or canola oil. If you want to use this CBD orally, it’s best to choose a carrier oil that you won’t mind tasting. If your main priority is for topical use, coconut oil works great on the skin and is not as pore-clogging as canola oil or olive oil.
Add 1 cup of your carrier oil to a pot. Put the pot on the stove, on low heat, and wait for the oil to simmer. You’ll know it’s ready when it starts to form small bubbles on the bottom of the pot. Then, crush 1 gram of your CBD crystals or concentrate into a powder form, and put the concentrate into the pot. Now, stir the mixture until the CBD has completely dissolved. To know your CBD is completely dissolved, there should be no more powder or chunks of crystal in the oil. If you notice that your crystals are not dissolving entirely, you can also use a cheesecloth to strain the oil and remove the excess crystals.
Step 3 – Let the mixture cool
Why would anyone choose to make their own CBD oil, when there are so many amazing brands on the market? Well, for the same reasons that people cook at home, and even grow marijuana at home. The benefits come down to price, quality control, and potency.
If you live in a state where growing is legal, you might have already gotten your hands on some marijuana seeds, and are planning your first grow. While this is a great way to take the entire process into your own hands, you don’t have to grow your own marijuana to make CBD oil.
Note: Do not let the oil exceed 118°C/245°F, as this will burn the CBD. This is where a thermometer will come in handy. If you let your oil get too hot, the CBD will dissolve and burn, leaving you with just plain oil.
CBD isolate is the most pure form of CBD you can obtain. The consistency is a fine, white powder visually similar to sugar or white sand. The isolate makes the top of my list simply for its versatility! Discover CBD’s Isolate is 99.8% CBD, meaning you get 998mg of CBD per gram – all in a tiny container. Since the product is pure CBD, it will not contain any other cannabinoids and is not considered a full spectrum product. While many people use the CBD isolate and find relief, it’s important to note that it’s possible to have different results with full spectrum products and isolate products.
Since the product is so concentrated in a small volume, most people choose to add their isolate to a larger base so they are able to accurately measure doses, which takes us to the first method of consuming CBD isolate:
You can vaporize the isolate in one of two ways. The most common way is by dabbing the isolate, using a dab rig set up. This will require you to have a water piece, a dab tool, and a torch. This method of vaping is not suggested for those that are not familiar with dabbing as it involves high amounts of heat and can be potentially dangerous. A dab rig isn’t the only way to vape isolate though, you can simply use a vape pen! If you travel this path, make sure to melt the isolate on the coil of your vape pen before inhaling – or better yet – use our isolate slab simply designed to be vaporized!
With so many CBD products available, it can become overwhelming when making a decision. There are oils, topicals, tinctures, edibles, vape products, etc. the list goes on and on. However one of my all-time favorite products often gets looked over, and it’s time to show it some love!
Since CBD isolate is naturally oil soluble, you’re able to fully dissolve the white powder into any oil! All it takes is warming up the oil (double boil method) of your choice (MCT oil is my favorite), and stirring in your CBD isolate. It usually takes about 10-15 minutes to fully dissolve. I typically use 2 oz. of oil and mix my entire gram of isolate, giving me about 16.5mg of CBD per ml. Flavoring like peppermint or vanilla can be added to your tincture for a sweet taste! Now you’ve got yourself an extra strength tincture that you didn’t break the bank for.
Once precipitation stops, flush or physically remove The CBD crystals from the reactor. Vacuum filter the crystal/liquid slurry to remove the mother liquor from the CBD crystals. Rinse the crystals with ice-cold pentane to rinse impurities from the crystal surfaces. More rinses with pentane can improve poor color, but losses in total yield will occur. Keeping the CBD and materials cold during this step will help give you a better yield.
Disclaimer – this post does not address all the safety issues for crystallization of CBD, Pentane and other volatiles can be very dangerous due to their low flash points. Don’t try this without consulting your safety officer and evaluating all of the possible safety concerns. As always, wear safety glasses and other personal protective gear when working in a lab.
The starting material should be extracted CBD oil that has been winterized and distilled. CBD distillate should be clear. Cloudiness means there are contaminants like water, waxes and fats. If the oil is cloudy try winterizing again until the oil becomes clear.
Collect CBD Crystals
The mother liquor still contains dissolved CBD. This solution can be reprocessed! One caveat is that the mother liquor will accumulate THC over time. This sets a practical limitation to the number of crystallization.
Set the bath to 5 °C. Slow the stirring. As the solution cools it will become more viscous. Adjust the stirrer to keep the RPM above 120. CBD crystals will spontaneously form or “crash out” of the pentane solution. Keep reducing the temperature to at least -10 C. What temperatures you use and how they change over time can change the growth of the crystals.
CBD distillate with 70 – 75% CBD content can be crystallized to produce CBD isolate (crystals) with a 90+% purity or higher.
