Tinctures have been around for thousands of years. “Tincture” refers to an infusion of a plant in a liquid base—often alcohol—in which the plant has been soaked and brewed for days, weeks, or sometimes months. Tinctures have been used to administer a wide range of herbal plant medicines around the world. They are easy to use, they are long-lasting, and you can make accurate dose measurements.
Oil infusions (also known as oil-based tinctures) are becoming more popular—because CBD is lipophilic (fat-loving), it is easily infused into the oil. Oil infusions can be made with liquid coconut oil, olive oil, hemp oil, sunflower seed oil, or any other edible oil. Oil tinctures are best used directly under or on top of the tongue because the mucous membranes of the mouth will absorb some of the tinctures directly before it reaches the stomach (where stomach acids begin to break it apart). When counting drops, it can be easier to put them onto a spoon first.
Vegetable glycerin, also known as glycerol or glycerine, is a clear, syrupy, odorless liquid produced from plant lipids. It is produced using an extraction process called hydrolysis. The process includes the use of pressure, temperature, and water. Vegetable glycerin has many applications in the world including food, cosmetics, and alcohol-free herbal tinctures, including cannabis tinctures.
Sublingual’s take effect in thirty seconds to two minutes and last about as long as other ingested products, for about six to eight hours. Under the tongue and within the mouth, a large number of tiny blood vessels can absorb cannabinoids into the bloodstream before they are swallowed
Administering medicine through food and snacks can be a delightful way to receive the benefits of CBD. Edibles are a fast-growing category in the emerging cannabis industry. They come in all shapes, sizes, and flavors, ranging from macaroons to muffins, gummy bears to lollipops, medicated trail mix and energy bars, chocolate and hot sauce—just to name a few of the sweet and savory edibles appearing on dispensary shelves.
Sublingual-Dissolvable CBD Strips
The sublingual dissolving strips (similar to breathe strips) that contain CBD medicine are fast-acting. They are convenient to carry and consume and are very discreet. There is no odor and they dissolve very quickly, within a few minutes. They provide effects in fifteen to thirty minutes and can last the typical six to eight hours.
Concentrated CO2 Oils
CO2 oils can be mixed with other carrier oils to make edibles or capsules (see more on how these concentrates are made on p. 52). CO2 oil is favored by patients needing a macro dose to treat their condition. The oil is extremely concentrated, often having a cannabinoid content of 50–75 percent.
It can be frozen, but some water must be added first because the fresh juice does not crystallize well. The other challenge is finding a good source of fresh leaves.
