Extract CBD Oil with Ethanol
Get the answer about how Ethanol can help the extraction of CBD Oil.
The use of ethanol to extract medicinal compounds from cannabis and other plants has been common in many cultures for centuries. In 1854, the United States Pharmacopoeia recommended ethanol-based tinctures made from “Indian hemp”.
Ethanol-based tinctures were used for the treatment of a variety of conditions including neuralgia, depression, bleeding, pain, and muscle cramps. These fragrant tinctures were a standard part of American medical care before the Marijuana Tax Act of 1937, which banned all forms of cannabis use.
But household cannabis tinctures have remained underground as folk medicine despite federal law, especially in underserved Latino communities. While a tincture made from a cannabis extract can have the same potency as the original flower, a concentrated version of the same tincture will be much more potent.
Today, food-grade grain alcohol is a widely used solvent to make a very potent, high-quality CBD-rich oil that is suitable for oral consumption. Ethanol extracts available at medical cannabis dispensaries are typically referred to as Rick Simpson Oil (also known as RSO) or Full Extract Cannabis Oil (FECO).
To make RSO or FECO, cannabis flowers are soaked in ethanol, shaken, and strained; then the rest of the oil is gently heated until only a viscous, highly concentrated, cannabinoid-infused mucus remains, which can be difficult to dose precisely due to its thickness.
Rick Simpsons Oil is a cannabis extract named after the medical marijuana activist who developed it. Simpson claims that applying the oil to cancerous spots on his skin cleared the spots in a matter of days.
Consumers are cautioned not to take a dose larger than a small grain of rice. With this type of cannabis oil, in particular, it’s important go slow and start low.
