I personally like to use strains that are high in both THC and CBD to make oil and salves. To learn more about the differences between strains, CBD and THC, see this article: “Sativa, Indica & Autoflowers, the Differences Explained”.
Furthermore, making cannabis oil is one of the most reliable ways to create medicated edible cannabis products. Even so, it is extremely difficult to determine the exact potency of homemade edibles or cannabis oil. Because of this, it is suggested to consume with caution in very small doses at first. Cannabis oil can be consumed on its own, or added to other edible cannabis recipes.
Cannabis oil is made by lightly heating (and thus infusing) cannabis in a “carrier oil”. Cannabinoids like CBD and THC, the most active components in cannabis, are both hydrophobic. That means they don’t like water, and are actually repelled by water molecules. On the flip side, CBD and THC are both fat-soluble. They like to bind with fatty acid molecules – such as those found in oil. When cannabis is steeped in oil, the THC and CBD molecules leave the buds or plant material and become one with the oil instead.
Hemp Oil, CBD Oil, THC, or…
Therefore, our cannabis oil recipe calls for decarboxylated cannabis as well. I provide very brief instructions on how to decarb raw cannabis below, but you can read further information about exactly how and why to decarb cannabis in the oven in this article.
Cannabis oil is the foundation ingredient for ultra-healing homemade topical lotions, ointments, and salves – my favorite way to use it! Both THC and CBD have excellent anti-inflammatory, antimicrobial, and antioxidant properties. Studies have shown that cannabinoids have the ability to reduce acne, fine lines and wrinkles, soothe redness and irritation, and balance natural skin oils. Also, cannabinoids (THC especially) are analgesic – meaning they reduce pain. I regularly use our homemade cannabis salve on my knees, ankles, and other aching or inflamed joints and muscles.
What is Cannabis-Infused Oil
Most cannabis oil recipes call for cannabis that has already been properly decarboxylated first. The most common and fuss-free way is to decarb cannabis in the oven, and then add it to oil over a very low heat afterwards – avoiding further decarboxylation. Some folks choose to decarb their raw cannabis on the stovetop simultaneously with the oil infusion process. However, that requires significantly more careful monitoring to hit that time-temperature sweet spot (and not ruin it).
Follow along with these step-by-step instructions to learn how to make homemade cannabis oil. We’ll also briefly discuss the science behind cannabis oil, and what types of cannabis to use to make oil. Finally, we’ll go over various ways to use homemade cannabis oil, including some notes about caution and dosing with edibles.
So the answer to the question about safety really doesn’t have anything to do with the solvent, rather the equipment chosen and the facility where the extraction is performed determine safety. The solvents commonly used in extractions today all have pros and cons, and all can be operated safely as long as proper guidelines and regulations are followed.
Short Path Distillation equipment
To further refine the CBD extract, and to isolate the CBD, the oil goes through Short Path Distillation. This works in much the same way as Winterization in that the extract is heated and each compound is then separated because each one has a different boiling point. In this way, each compound is isolated and can be used by itself.
Research is showing that CBD extract has a huge potential in the medical market. CBD’s common benefits are treating anxiety, reducing pain and inflammation, helping prevent seizures, among many others. Because it’s a natural extract, there are few, if any, side effects. The extract works with the body’s endocannabinoid system, which is the system’s method of regulating processes, like pain, mood, appetite, and memory. CBD works with the natural system rather than being an unnatural substance, so the body doesn’t try to reject it. CBD extract may be sourced from cannabis or hemp, most typically from hemp, which is naturally high in CBD. Cannabis can also be bred to have low THC levels and high CBD levels, but it’s possible that the THC will get concentrated and included in your final products.
Hemp and cannabis oil extraction processes and techniques.
I addressed the safety question in the first part of the answer, in the second part I’ll address the efficiency question: What is the most effective way to extract CBD-rich oil?
A major problem facing the cannabis industry today is a lack of commonly accepted standards – as evidenced by the question referring to “CBD-rich”. Does “CBD-rich” mean 40% CBD? 99% CBD? And CBD in what form, CBD, CBD-A or some combination? There are groups that are working towards creating standards, such as FOCUS and ASTM, but they have not been widely accepted yet. Without standards, quality also becomes difficult to determine because the only standard is personal subjectivity.
Once extracted, the mixture is combined with 200 proof alcohol and stirred vigorously until completely mixed. It’s then placed in a deep freezer overnight. In the morning, the mixture looks cloudy and is ready for filtration. One way to filter out the fats, etc. is to run it through a filter paper into an extraction jar. A common piece of equipment for this is a Buchner Funnel. Once it’s been filtered to satisfaction and the undesirable elements have been removed, it’s time to remove the alcohol. This is done using heat. The extraction is warmed and as its warmed, the alcohol evaporates since the boiling point of alcohol is lower than the oil. The removed alcohol may then be used on a different batch of crude oil.

Thanks for the great question! There are really 2 questions here, so I’ll try to answer them separately.
