How to extract CBD hemp oil from cannabis leaves?

What is Cannabidiol (CBD Oil)?
Probably each person has heard about marijuana (cannabis). This is a well-known psychoactive drug, which is used for recreational and medicinal purposes. Some people may become addicted to it, so in many countries it is prohibited. However, cannabis contain a lot of substances which may have healthful effects.
CBD belongs to the group of cannabinoid substances contained in cannabis. The principal cannabinoid which is responsible for narcotic properties of marijuana is tetrahydrocannabinol ((−)-trans-Δ⁹-tetrahydrocannabinol, THC). It causes “getting high” feeling, impairs the ability to drive, and also leads to intoxication of the body. However, CBD is not a psychoactive substance and cannot cause addiction. Therefore, it can be successfully used to treat certain conditions, such as pain, without the risks to mental health.
Why Should You Make Your Own CBD Oil?
There are plenty of reasons for learning how to make CBD oil such as price, quality, and being able to control the potency of the oil. Before we dive into the recipe we recommend, let’s talk about what each of these benefits can mean for you.
Price: By using concentrates to make your CBD oil, you can reduce your costs by over 50% compared to retail brands. 1000mg of CBD oil can cost you well over $100 from a retailer, but by using this recipe, the same amount would cost less than $40.
Quality: Due to the lack of regulation, there is no quality control or standards for the brands selling CBD oil to follow. This means that there is no way of knowing for sure if the products contain harmful chemical additives or if the hemp was grown with toxic herbicides and pesticides. When you make your own CBD oil, there is no doubt in the contents of your product.
Potency: You can customize the strength to be the exact dosage that you need per serving. You can also be sure that the potency is accurate. Most retail brands don’t contain the amount of CBD that’s labeled on the bottle.

Hemp Extraction Methods
Once you have your Industrial Hemp Plant Material, there are three main methods of extracting the CBD; CO2, ethanol, or oil extraction.
CO2 Extraction
CO2 extraction is the most sophisticated and effective way if you want to know how to make CBD oil like a professional. Most of the professionally made CBD products online are made from CO2 extracted CBD because it is by far the best method. However, CO2 Extraction requires a lot of expensive equipment and some chemistry knowledge. Pressurized CO2 is used to pull out the CBD from the plant. Carbon dioxide’s task is to act as a solvent at a certain pressure possessing no other kind of dangers.
Ethanol Extraction
The ethanol extraction oil method is cheap and easy. However, it can destroy some CBD content in the hemp plant material, making it not as effective. The process starts by adding the liquid to the plant material, which further separates the cannabinoids and flavor. The derived liquid is then heated to evaporate it down to CBD oil.
Solvent-free extractions
It is worth mentioning that more basic techniques also exist for preparing cannabis and extracting desirable components from the plant matrix. Kief, for example, can be separated from cannabis buds simply by grinding and sieving. These crystalline formations make up part of structures known as trichromes which are found on many plants, including cannabis. Cannabis trichromes are primarily protective structures produced by female plants when flowering. Their intense bitter taste and strong aromas render the plant unpalatable to herbivores and, they are also believed to inhibit some fungal growth. When separated from cannabis inflorescence, kief looks just like a powder or pollen. And, as cannabinoids and terpenoid production is particularly concentrated in trichromes this powder can be added to cannabis preparations to boost potency or consumed alone as a standalone product. Traditional hash, or hashish, is another example of a solvent-free, more basic cannabis extract. Again, the idea is to separate the trichromes from the plant material as they contain the highest concentration of desirable compounds. Two main methods exist for creating hash, one involves taking frozen cannabis buds and breaking them into smaller and smaller parts over a screen. In the process, trichromes are separated from the plant and fall through the sieve and then pressed into blocks. The other primary method of solvent-free hash extraction involves using ice water to separate the trichromes from the bud. After drying they can then be pressed in a hash block. Rosin has also become very popular over the last couple of years. Produced from flowers, hash or kief, rosin is a translucent substance typically with a sap-like consistency. It’s made by applying heat and pressure to the material you wish to extract from and results in a product that’s very similar to the more time-consuming, expensive and, solvent-based butane extraction. Analytical testing has demonstrated that this simple approach effectively extracts cannabinoids and terpenes with absolutely no risk of leaving behind toxic residual solvents like butane. The simplicity of this approach is without a doubt its biggest draw. Enthusiasts are able to produce highly potent rosin extracts with a hair straightener, some baking parchment, a collection tool and, some heatproof gloves. rosin presses are also available to process material on A flat heat press mechanism is used to squeeze the material but at a specific heat and pressure and the extract is scraped off.

How to make your own CBD oil

Before you begin the extraction process, it’s important to think about how you’re going to use the oil. If you intend to use it orally or sublingually (under the tongue), then it’s critical to decarboxylate your plant material before carrying out the steps below. Decarbing converts the cannabinoid acid CBDA into the desired molecule CBD via heat. During the actual extraction process, temperatures are only raised high enough to cause the volatile alcohol to evaporate. If you need to decarb your weed, you can find out how to do so in our decarboxylation guide.
Now that we’ve covered these important points, let’s take a look at the ingredients and equipment needed for the process.
INGREDIENTS
- Around 30g of ground buds or 60–100g of ground, dried shake or trim - High-proof, food-safe grain alcohol
EQUIPMENT
- Mixing bowl - Fine strainer such as a piece of cheesecloth or a sieve - Catchment container - Double boiler (a set of two fitted saucepans/pots stacked together with space between them) - Wooden spoon - Spatula - Funnel - Plastic syringe
INSTRUCTIONS
STEP 1
To begin, place your decarbed buds or trim into the mixing bowl and pour in enough alcohol to completely submerge the plant matter. Use the wooden spoon to stir the material for 5 minutes. During this time, the alcohol will pull out the desired constituents such as CBD and terpenes. Stirring will help to accelerate the process and dislodge the trichome glands that produces these substances.
STEP 2
Next, you’ll need to separate the CBD-rich alcohol extract from the plant matter. Strain the solution through a piece of cheesecloth or a fine sieve into a bowl below. You’ll notice that the alcohol has a dark green color to it. Repeat the process above with fresh alcohol a few more times to get the most out of your buds or trim. Eventually, the extract will start appearing more clear in color, a sign that the material is now spent.

STEP 3
Now it’s time to set up the double boiler. If you don't have a setup like this already, an easy makeshift option is to fill the bottom of a saucepan with water, then place a stainless steel bowl into the saucepan that fits snugly, but doesn’t touch the bottom of the pan.
Pour the alcohol extract into the stainless steel bowl/top of the double boiler and apply gentle heat. High-proof alcohol is highly volatile and will evaporate at a low temperature. Keep the heat down and turn the heat on and off where necessary. It’s important to carry out this process away from any naked flames and ideally under an extractor fan or outdoors. The vapor produced when the alcohol evaporates is highly flammable and poses a real fire hazard.
Keep stirring the extract for 15–20 minutes while the alcohol evaporates. The mixture should turn extremely viscous.
STEP 4
After all the alcohol is removed, the extract should display a thick, tar-like consistency. Whilst it’s still warm, draw it up into a large syringe or multiple smaller ones. This makes it easy to store and administer.
