Cannabidiol (CBD), an extract that many use as an anti-anxiety or relaxation tool, comes from the Cannabis sativa plant and cannot be divorced from this original source. Cannabis sativa has many different variations, and not all of these contain significant amounts of CBD. Prior to the gradual ending of cannabis prohibition in many locales, CBD was practically eliminated from the commercial black market to maximize profitability of the psychoactive cannabinoid content of the plants through selective breeding, according to many of the black-market growers I have spoken with throughout the years. The reason CBD is now widely accessible is most assuredly due to the change in social perceptions of this once-outlawed plant and the legalization of this plant in many locales. Without cannabis legalization, CBD would be difficult to acquire—and there would be no testing to ensure that consumers receive the product they are paying for.
In the process of developing recipes, I spent much of my time talking to CBD farmers and exploring their lush farms. I am forever grateful to my friends at Feather Canyon Farms in Del Norte County, California, for introducing me to some of the most impressive plants I’ve ever seen in my life. Beforehand, my experience with these plants had been limited to small indoor grows and the product offerings of our legal cannabis dispensaries.
One of the things I learned from the CBD farmers is that CBD can be an unstable and fleeting trait in cannabis plants. CBD production doesn’t just depend on the genetics of a plant, but the methods of growing, and what is also recognized in grape and wine production as the terroir. New strains of CBD-rich cannabis are being developed for the legal market all the time. I haven’t been able to try them all, but I’ve had the privilege of trying some of the most well-known strains, such as Harlequin, Harle-Tsu, ACDC, Cannatonic, Charlotte’s Web, Sour Tsunami, and a rare crop of Golden Goat, which expressed more than 8% CBD. This list is by no means complete in terms of CBD-rich cannabis strains available.
Hemp, the low-to-no THC variety of Cannabis sativa grown for the oilseed and fiber it produces, can also produce CBD in varying amounts. Both wild hemp and cultivated hemp can produce CBD in their resins. No matter what variety of Cannabis sativa produces CBD, the molecule is always the same.
Farmers, Plants, and Test Results over Brands: How To Select CBD Products
I believe that quality, whole-plant infusions and extractions matter. Epidiolex, the FDA-approved drug, is a whole-plant extract of CBD, purified, standardized, and manufactured for consistency. It’s rare as far as pharmaceuticals go; GW Pharma grows and processes their own cannabis to make therapeutic pharmaceuticals. Whether you are in need of a pharmaceutical treatment or are using CBD as a home remedy or for pleasure, you should be using whole-plant infusions and extractions. The cannabis farmers I spoke with have expressed a similar belief.
I am often asked about which brands of CBD are the best and which products to choose. But the truth is that when it comes to CBD, brands do not matter. Farms and plants matter. Selecting quality CBD-rich cannabis plant products begins with the farm they are grown on. Before you purchase any CBD product, know the farm and farmer. This is an easy task in most of our state-legal cannabis dispensaries, as this information will be readily available and even used as a marketing tool. This information is harder to find if you are purchasing CBD products from the over-the-counter herbal supplement market.
CBD products sold over the counter in the mainstream herbal supplement market do not have the oversight and regulated testing that most of our state-legal dispensary systems have. If you choose to purchase CBD products in the herbal supplement market, you must rely on the information they provide to you in terms of acquisition of plant material and test results. You must also be aware that there is controversy (both legal and scientific) surrounding the purchase of CBD products over the counter through the mainstream herbal supplement marketplace.
Test results matter. The herbal supplement marketplace is largely unregulated and a bit like the Wild West. An exposé in the New York Times in 2013 detailed some very disturbing problems with the herbal supplement marketplace and the fact that consumers often do not receive the products they are paying for. As well, CBD supplement merchants in the over-the-counter herbal supplement market have been cited by the FDA for many violations around the labeling and distribution of their products.
Certainly, I am not saying that all herbal supplement products are bad. What I am saying is that it is a wise decision as a consumer to seek out information and verify it if you are purchasing supplement products of any kind. And you should also be aware that not all locales will regard the purchase of CBD products as a legal activity.
The functionality of this book is to show you how to seek, find, and enjoy CBD-rich cannabis. Facts and aesthetics both matter if what you seek is a quality product and a satisfying experience.
In the recipes that follow, the focus is on whole-plant CBD-rich cannabis extractions and infusions, as these high-quality, artisanal, and farmer-centric whole plants and whole-plant resins will unfold themselves with fragrant and delicious complexity in your kitchen. My wish is for you to enjoy and benefit from everything CBD-rich cannabis offers without missing anything.
CBD to THC Ratio Selection and Dosing
Selection and dosage amount of CBD or CBD: THC is a very individual process and an ideal dosage that works as a one-size-fits-all amount does not exist. If you have concerns about what is best for you, this is something you should discuss with your personal physician. There are also MDs and DOs who specialize in cannabis therapeutics who can guide you based on your current health situation. If you are considering CBD for therapeutic medicinal purposes, it’s a good idea to consult with a physician who has knowledge and experience in this area before you begin.
I’ve developed a checklist that you can use and that I hope will guide you to the products that are worthy of your consideration:
— Is the name of the farm or farmer disclosed on the product label or available from the company or merchant selling the product?
— Does the product have test results from a third-party lab independent of any brand or manufacturer? Can you verify these results independent of a company, merchant, or legal dispensary?
— Do the test results include more than just CBD and other cannabinoid content?
— Are there test results for pesticides, mold, and other contamination? (Cannabis is a powerful soil remediator and easily absorbs toxic chemicals from the soil it is grown in.)
— If the product you would like to purchase is raw plant material, have you scoped it to check for mold or insects? Most dispensaries have magnification scopes for their customers to use—take advantage of this.
— Does the product look fresh, and does it smell fresh and clean? Is the product or plant material dated with harvest time or an expiration date?
CBD Farmer’s Oil Recipe with Whole Flowers
When one considers flavors, textures, freshness, effects, and fragrances as the starting point of evaluating a quality CBD oil product, this recipe will produce a gourmet oil extraction that will impress even the most experienced connoisseur.
Farmers know best. And this oil recipe was given to me by one of the most hardworking and knowledgeable CBD farmers I have met, Mr. Jesse Davis of Feather Canyon Farms in Del Norte County, California.
I experienced many pleasant surprises while sampling this oil at home, and the process of making it was even more surprising. Rich in both CBD and the natural terpenes of the Harle-Tsu CBD-rich cannabis plant, this oil is a gorgeous emerald color with a sublime minty and herbaceous flavor that I have never experienced with a CBD oil previously. This oil was completely non-intoxicating, but it was very pleasant and relaxing.
This oil, processed in MCT oil (fractionated coconut oil) at a low temperature for 24 hours, produced a CBD oil product that has lab tested at 10mg CBD and less than 1 mg
THC per 1ml dose. How low was that temperature? 175°F (80°C)—a temperature much lower than what is typically expected for a complete decarboxylation. What made the difference? The slow processing of this oil over a 24-hour period. Decarboxylation takes place with temperature, time, or in this case, both time and temperature.
I am satisfied that the flavor profile of this oil was only possible due to the careful, low-temperature processing technique that retained the majority of naturally occurring terpenes in the whole cannabis flowers from the CBD-rich Harle-Tsu cannabis strain grown in the mountain region of Del Norte County. Flower quality really does matter when it comes to producing an exquisite CBD oil such as this one.
This makes approximately 10 oz. (296ml) of CBD oil, but you can increase or decrease the amount of oil or flowers depending on the CBD concentration you desire.
10 oz. (296ml) MCT oil or more (otherwise known as liquid fractionated coconut oil)
1 oz. (28g) or more whole CBD-rich, low-or-no- THC cannabis flowers, cured, dried, and chopped
- This recipe requires a slow cooker with a low heat setting to process this oil correctly. Add the chopped cannabis to the slow cooker.
- Pour the oil over the cannabis, making sure that all the flower material is covered. If you need to add a little extra oil to cover the flowers, you should do so at this time. Cover the slow cooker and set to the low or low cook setting (depending on your model).
- Within at least 3 hours, your slow cooker should reach the final processing temperature of about 175°F (80°C). Use a candy thermometer to verify the temperature and adjust if necessary. Stir the oil and plant material at this time and cover the slow cooker once again.
- Every few hours, stir the oil and flower material to evenly distribute the infusion throughout the process. Do not stir frequently, as this will allow more of the volatile terpenes to escape into the air. To preserve as many of the volatile constituents as possible, such as terpenes, leave the lid on the pot throughout the entire process. This can be left to process overnight without stirring.
- After the 24-hour period is over, cool the oil by unplugging the slow cooker and allowing the materials to remain in the pot and the oil to cool to room temperature a few more hours.
- Strain the oil from the plant material through cheesecloth and into a clean glass jar. The oil is now ready to use by itself in measured doses or in any recipe.
Store in a cool, dark, and dry area. Use within 6 months for freshest flavor

How to Make CBD Oil
Many people use CBD oil to reduce inflammation, soothe pain, or improve their body’s response to stress. And it’s super easy to make at home, too. Plus you can use healthy fats and you’ll know exactly what you’re putting into your bottle, avoiding the refined oils and additives that commercial producers sometimes add.
If you’re looking to make cbd oil, you’ll need just two ingredients: hemp and a carrier oil like olive oil. The result is a vibrantly herbaceous infused oil with soothing anti-inflammatory properties.
What is CBD oil?
CBD oil is a non-intoxicating herbal remedy made from hemp flower. It is rich in cannabidiol, a type of compound found in cannabis that has strong anti-inflammatory properties. One of CBD’s benefits is that it conveys the beneficial properties of cannabis without the high since it contains little to no THC.
Many people take CBD to help combat inflammation, anxiety, or restless sleep. Some research suggests it helps protect and support nervous system health (1) and may reduce pain (2), while other research suggests it supports gut health and proper immune system function (3).
To make CBD oil at home, you’ll need to follow a simple two-step process: decarboxylation and infusion. While it sounds complex, decarboxylation is a simple process of precision heating that activates beneficial compounds in cannabis. The second step, infusion, releases those compounds into a carrier oil. Infused oils are easy to take, and oil makes these compounds easier for your body to absorb, too.
Activating the CBD
In order to make CBD oil, you need to extract cannabidiol from hemp first. Further, you need to activate through a process called decarboxylation. The compounds in cannabis plants aren’t active or bioavailable on their own; rather, they’re activated through heat which is why the plant is traditionally smoked.
Rather than smoking, you can activate these compounds through other means of heating. Some people bake hemp flowers in a slow oven for about an hour or use a slow cooker. These methods are inexpensive, but they’re also imprecise and may not activate all the CBD.
To activate CBD efficiently and to get the most from your plant material, you’ll need a precision cooker (also known as a decarboxylator) which can maintain exact temperatures needed for the full activation of CBD and other cannabinoids. With precision heating, decarboxylators extract a higher percentage of beneficial plant compounds than cruder methods and are a worthwhile investment for anyone who takes CBD oil regularly or wants to make a consistently good product.
Where to Find a Decarboxylator. Commercial CBD oil producers use huge decarboxylators capable of activating the cannabinoids in several pounds of cannabis; however, if you’re making it at home, you’ll need a smaller version.
We used the Ardent Flex for making this CBD oil. With multiple settings, you can use it to activate CBD as well as similar compounds. And, you can also use it to make herbal infusions. Save $30 with code NOURISHED.
What you’ll need to make CBD oil
To make CBD oil you only need two primary ingredients: hemp and a carrier oil. Hemp flowers that are high in CBD will yield the best results, and if you can’t find them locally, you can order them online. After decarboxylating the hemp flowers, you can then use them to make a CBD-infused oil.
High-CBD hemp flower
Depending on their strain, cannabis may contain large or relatively low amounts of CBD. When you make CBD oil, choose a strain with a high CBD content so that you can extract the most beneficial compounds into your homemade oil.
Where to Find High-CBD hemp flower. Since hemp flower is non-intoxicating with negligible to no-detectable THC content, it is legal on a federal level. You may be able to find it locally; however, your best bet is to purchase it online.
Sacred Smoke Herbals sells high-CBD hemp flower that’s organically grown, lab-tested, and available in all 50 states. Use coupon code NOURISHED15 for 15% off.
Finding the right carrier oil
A carrier oil is an oil that you use for herbal infusions. Coconut oil and MCT oil (which is derived from coconut) are popular carrier oils both in commercial and homemade CBD products.
I recommend trying extra virgin olive oil because it has good flavor and high antioxidant levels. Even more, research by ardent shows that olive oil is more successful at extracting the plants’ beneficial compounds.
Making CBD oil at home is easy, and you need only a few ingredients. It's a two-step process that involves heating and then infusion into a carrier oil.
