How to Make CBD Oil from Hemp Flowers

How to Make CBD Oil from Hemp Flowers – As new studies surface about the therapeutic potential of cannabidiol, demand for CBD-infused products is skyrocketing to unprecedented highs.

CBD oil, in particular, has become widely popular. CBD oil and other CBD products come in the form of tinctures, vape juice, gummies, and many other goods.

Users report that CBD oil offers calming, soothing, and nonpsychoactive effects. Many suggest that CBD oil may relieve pain and stress, reduce inflammation, stimulate the appetite, and deliver other benefits as well. Medical users have found CBD oil highly valuable, as it appears to ease pain while leaving users sober and clearheaded.

Although many medical and recreational users are familiar with CBD oil, they may not understand how to make CBD oil from hemp flowers. The production methods used to manufacture CBD oil help determine the quality and purity of the product. Many consumers also may be unaware that they can safely and easily make their own CBD oil at home.

This article describes what CBD oil is, how to make it, and which methods produce the highest-quality oil.

What Is CBD Oil?

CBD oil is a hemp extract combined with a carrier oil such as coconut oil. Typically, processors use the stalks, stems, and flowers of hemp plants to develop hemp extracts. To be clear, hemp is a variety of cannabis with less than 0.3 percent THC levels. This minuscule THC content is the reason hemp is federally legal in the United States. However, many state and local jurisdictions have enacted their own laws or ordinances regarding hemp and CBD-infused products. As such, consumers and manufacturers should always research these laws and ordinances before purchasing or making these products.

Although hemp is low in THC, many breeders have developed strains that are rich in other cannabinoids such as CBD. Hemp flower also contains terpenes and flavonoids that, like CBD, may possess therapeutic properties.

Types of CBD Oil

CBD oils typically fall into three main categories: full-spectrum, broad-spectrum, and CBD isolate. Manufacturers define each category by the types of hemp compounds present in the oil.

Full-Spectrum CBD Oil

Full-spectrum CBD oil contains all of the compounds found in hemp plants. This type of CBD oil is minimally processed and contains various cannabinoids, terpenes, and flavonoids. It may also include other hemp compounds such as proteins, fatty acids, chlorophyll, and fiber. Full-spectrum oil contains many hemp compounds. Consequently, its therapeutic effects are more pronounced than those of broad-spectrum oils and CBD isolate. However, full-spectrum CBD oil contains trace amounts of THC (usually less than 0.3 percent). Although this amount of THC isn’t considered sufficient to cause psychoactive effects, it is enough to show up on some drug screenings.

Broad-Spectrum CBD Oil

Broad-spectrum CBD oil contains all of the cannabinoids, flavonoids, and terpenes in hemp, except THC. This psychoactive compound is removed from broad-spectrum hemp oil, making broad-spectrum oil an excellent choice for users who are highly sensitive to THC or who may be subject to drug screenings.

CBD Isolate

CBD isolate is a highly processed hemp extract that isolates CBD into its purest form. The processing removes all of the other desirable cannabinoids, terpenes, flavonoids, and other hemp compounds. Although this type of extract is generally more affordable than full-spectrum and broad-spectrum oils, it may not be as potent.

Benefits of CBD Oil


The nonpsychoactive cannabinoid CBD may offer a wide array of therapeutic benefits. Studies show that it may reduce stress, relieve pain and inflammation, and stimulate the appetite. Because CBD is nonpsychoactive, it does not produce the “high” typically associated with THC consumption. Researchers are currently studying many other reported CBD benefits as CBD-infused products gain acceptance in mainstream medical markets.


Some types of CBD oil may contain cannabigerol (CBG). This cannabinoid is the precursor from which all other cannabinoids form. Like CBD, this cannabinoid is nonpsychoactive, and will not impair one’s senses. Though we don’t know much about CBG yet, preliminary research suggests it may offer many benefits to consumers. For example, some users maintain that it may reduce the negative side-effects of THC, and some report that it stimulates the appetite and reduces pressure in the eyes.

Other Cannabinoids

More than 100 cannabinoids develop in hemp flowers, each with its own potential therapeutic properties. Full-spectrum and broad-spectrum CBD oils may contain cannabinol (CBN), cannabichromene (CBC), and trace amounts of other cannabinoids that may provide an array of desirable effects.


Full-spectrum and broad-spectrum CBD oils contain terpenes. These oils are the source of the unique aromas associated with hemp plants. The plants produce terpenes to protect themselves from predators and to lure pollinators. Terpenes may also be beneficial to humans. Like cannabinoids, terpenes may possess therapeutic properties. For example, myrcene, a common hemp terpene, seems to possess powerful antibiotic, anti-inflammatory, and analgesic properties. More than 100 types of terpenes develop in hemp plants, each with its own distinct effects.

Flavonoids are another group of desirable compounds found in full-spectrum and broad-spectrum hemp oils. They are the phytonutrients that give fruits and vegetables their vibrant colors. Like cannabinoids and terpenes, flavonoids may provide therapeutic benefits. Some flavonoids may possess anti-inflammatory, antioxidant, and antibacterial properties and offer other potential benefits. Hemp contains approximately 20 types of flavonoids.

The Entourage Effect

Each of the compounds listed above has its own potential health benefits. However, when these compounds combine, their effects may be more potent. The synergistic quality of various combined hemp compounds is called the “entourage effect.” This would suggest that combining CBD with other hemp compounds could make the effects of CBD even more pronounced. Users may experience the entourage effect by consuming broad-spectrum CBD oil, but full-spectrum oil might be even more effective due to the trace amounts of THC.

Why Make CBD Oil from Hemp Flowers

CBD oil is a key ingredient in many products, including topical lotions, edibles, and tinctures. Users report that these products may possess anti-inflammatory, antioxidant, and antimicrobial properties.

Unfortunately, many CBD-infused products are expensive and highly processed. Some may not contain enough CBD to deliver a significant effect. By making their own CBD oil, consumers gain control over the quality of the ingredients used and the oil’s relative potency. Moreover, they can choose a strain of hemp or cannabis that suits their preferences, keeping in mind that each strain has its own unique combination of cannabinoids, terpenes, and flavonoids.

By using a simple oil-extraction method, consumers can easily and affordably make their own CBD oil, tailoring it to their needs and preferences.

How to Make CBD Oil from Hemp Flowers

Before making CBD oil, processors must extract the CBD from hemp flower, then infuse it into a carrier oil. There are several ways to go about this, though. The most common extraction methods are carbon dioxide extraction, alcohol extraction, butane extraction, and oil extraction. Each method presents its own advantages and drawbacks.

Carbon Dioxide Extraction

CO2 extraction is a commonly used method for separating CBD and other compounds from hemp plants. This method is popular because CO2 is not flammable and does not contaminate the CBD oil with toxic residues. CO2 extraction is also attractive because it has a much lower environmental impact compared to other extraction methods. Moreover, CO2 extraction produces high-quality extracts that are rich in cannabinoids. However, this method requires specialized equipment and may yield less hemp extract than other extraction methods. Processors group CO2 extraction into three categories: supercritical, mid-critical, and subcritical.

The supercritical method involves applying heat and pressure to CO2 until it becomes “supercritical.” Supercritical CO2 displays properties of both a liquid and a gas. In this state, CO2 can easily penetrate the tissues of hemp buds and dissolve the desirable compounds. This method is great for producing CBD isolates, as it yields a high amount of CBD. However, it may destroy many other hemp compounds.

Mid-critical and subcritical extractions involve the same process as supercritical extraction. However, processors need to apply less heat and pressure to the CO2. These methods typically yield less CBD extract than supercritical extraction, but they preserve the other hemp compounds. These methods are excellent for producing full-spectrum extracts because they retain most of the cannabinoids, terpenes, and flavonoids in hemp.

Alcohol Extraction 

Alcohol extraction is a simple and affordable method of extracting hemp compounds. This extraction method is advantageous because ethanol is generally considered safe for food products and will not contaminate the CBD extract. Using this method, manufacturers steep hemp buds in ethanol or another high-proof alcohol, stripping CBD and other compounds from the flowers. Ethanol can form bonds with both water-soluble and fat-soluble compounds, making it capable of extracting a wide range of components from hemp buds.

Because alcohol can dissolve a multitude of compounds, alcohol extracts may require refinement and filtration. This will remove undesirable compounds such as chlorophyll and plant waxes. Manufacturers must be careful when using this method, as alcohol is flammable. When performed cautiously, alcohol extraction is a great method for producing full-spectrum CBD oil.

Butane Extraction

Processors use butane and other petroleum-based products like propane to dissolve hemp compounds. This method is effective because butane, for example, is capable of dissolving cannabinoids, terpenes, and flavonoids, while it excludes undesirable compounds such as chlorophyll. Although it is effective, butane extraction is generally not recommended for producing CBD oil, as it may leave toxic residues in the extract. Butane extraction can also be dangerous, as hydrocarbons are highly flammable.

Oil Extraction

Oil extraction is one of the oldest hemp extraction methods. It is simple and inexpensive to perform. Olive oil, coconut oil, or other carrier oils help draw out the desirable compounds from hemp buds. This method produces a lower yield of active cannabinoids than other extraction techniques produce. However, oil extraction is safe to do at home without the use of specialized equipment.

DIY CBD Oil Recipe: Oil-extraction Method

  1. Acquire some high-quality organic hemp buds that are rich in CBD. Red Bordeaux, from Diet Dank, is an excellent choice for use in making CBD oil.
  2. Tear the buds into small pieces or grind them with an herb grinder, and place them on a cookie sheet. Heat the buds in the oven at 250 degrees Fahrenheit for 25 to 30 minutes. This will decarboxylate the flowers, turning Cannabidiolic acid into CBD.
  3. Add one cup of coconut oil to a cooking pot or slow cooker and heat on low until the oil melts.
  4. Mix in seven to ten grams of decarboxylated hemp buds with the oil. (You can adjust the amount of hemp buds to suit your preferences.)
  5. Cook the mixture over low heat for 45 to 60 minutes, stirring occasionally. Use a thermometer to ensure the mixture does not exceed 200 degrees Fahrenheit.
  6. Line a strainer with cheesecloth and strain the mixture, separating the oil from the plant matter. To prevent injury, wait until the mixture has cooled before straining it.
  7. Pour the oil into a sealable glass storage container and store it in a cool, dark place. If refrigerated, the oil should remain fresh for up to one year.

How to Use CBD Oil

Consumers can use CBD oil in a variety of ways. They can add it to salves or apply it directly to the skin, use it as a cooking oil when making CBD-infused edibles, add it to drinks, or even apply a few drops of CBD oil under the tongue for sublingual dosing.

Summary: How to Make CBD Oil from Hemp Flowers
