The process of obtaining CBD typically involves extracting it from the hemp plant itself, rather than from pre-existing oil. Based on common methods, one effective way to achieve this is through solvent extraction, which yields a concentrated oily residue containing the desired hemp compounds.
It appears there might be a slight misunderstanding in the original question; the reference provided describes how to extract CBD from hemp plant matter using solvents, which results in an oily substance, rather than extracting CBD from oil.
Here's a breakdown of the solvent extraction method as referenced:
The Solvent Extraction Process
Solvent extraction is a widely used technique for separating cannabinoids like CBD from raw hemp material. It relies on the ability of certain solvents to dissolve the desired compounds.
Steps in Solvent CBD Extraction
The fundamental steps involved in a typical solvent extraction process are as follows:
- Running the Solvent: The process begins by running the solvent in question—typically either butane or ethanol—to the hemp plant matter. The solvent is passed through the dried and cured hemp material.
- Stripping Cannabinoids: As the solvent moves through the plant matter, it strips the cannabinoids into the liquid. This means the CBD and other beneficial compounds from the hemp are dissolved into the solvent.
- Evaporating the Solvent: Once the solvent has collected the cannabinoids, the next crucial step is to remove the solvent itself. The liquid is then evaporated so as to leave behind a concentrated oily residue with the hemp compounds in. This evaporation can be done using heat, vacuum, or other methods depending on the specific solvent and desired outcome.
The resulting concentrated oily residue is the crude extract containing CBD, potentially other cannabinoids, terpenes, and other plant compounds, depending on the selectivity of the solvent used. This oily residue is then often further refined or diluted into carrier oils (like MCT oil or hemp seed oil) to create finished CBD oil products.
Using solvents like ethanol or butane is popular because they are effective at dissolving a wide range of cannabinoids and terpenes from the plant material.
