With an ethanol extraction, the chlorophyll remains which gives the oil its green colour. This is part of the phytocomplex (meaning, the mixture of plant extracts).
As we’ve mentioned above, in its natural state, the Cannabis sativa L. plant matter contains chlorophyll so with less filtering, the colour will be green like the plant. If it has been filtered to remove the phytocomplex, the oil may appear more golden coloured.
1. The extraction method
After extraction the manufacturer can either bottle the extract or isolate it further. For an isolate oil, only the CBD from the plant is extracted and the isolate can give the oil a golden colour.
The amount of carrier oil added to the extract could have an impact on the colour of CBD. That’s because the more you dilute, the more likely the colour of the extract will change towards the colour of the liquid with which you’re diluting it.
What is green CBD oil? In its natural state, the Cannabis sativa L. plant matter contains a pigment called chlorophyll which makes the plant appear green. If you have an oil that contains phytocomplex (like ours at CBII), then the green colour is the result of the oil containing some of this natural plant matter.
To make CBD oil, one must start with CBD -rich plant material. There are several ways to extract CBD oil from cannabis. Each method has its pros and cons. Some are safer and more effective than others.
CO2 extraction is the most prevalent commercial method – as well as one of the safest ways – of separating CBD and other cannabinoids from cannabis biomass. At room temperature, carbon dioxide is a gas. But under high pressure and fluctuating temperature, CO2 liquifies while still maintaining the fluid dynamics of a gas. In this “supercritical” state, CO2 acts like a solvent, which flushes out the active ingredients from the plant matter.
Often sold in plastic, needleless syringes to make dosing and administration a little easier, RSO should contain the full spectrum of cannabinoids extracted from the plant. This means that a small amount THC will also be present in a CBD -rich ethanol extraction. Consumers are cautioned not to ingest a dose larger than a small grain of rice. With this type of cannabis oil, in particular, it’s always best to start low and go slow.
As the pressure drops, a crude, waxy, CBD -rich substance, golden in color, separates from the gas and deposits into a collection vessel. Afterwards, the golden oil undergoes a process known as “winterization,” which purifies and refines the extract to increase its quality and value. The plant waxes, which are not appropriate to include in certain kinds of products, are filtered out, resulting in a safe, clean, CBD -rich oil that is free of chlorophyll.
These odiferous tinctures were a standard part of American health care prior to the passage of the Marihuana Tax Act of 1937, which prohibited all forms of cannabis consumption. But homemade cannabis tinctures persisted as an underground folk medicine, particularly in marginalized Latino communities, despite federal law.

Because CBD oil is often made from industrial hemp, in which case CBD must come from the seeds and stalks of the plant, CO2 extraction methods are most often used. CO2 extraction methods use a combination of temperature and pressure to extract the CBD from the plant material. In the CBD industry, CO2 extraction methods are often considered the gold standard because they don’t involve the use of chemical solvents and do a better job of preserving CBD and other beneficial chemical compounds.
How CBD Oil is Made
While there’s a lot of discrepancy between products labeled full, complete, and broad spectrum due to lack of industry standards, most companies provide third-party lab results on their website so you know exactly what’s in your CBD.
CBD isolate is the purest form of CBD, produced by removing all other plant compounds found in hemp including terpenes, flavonoids, chlorophyll, and other cannabinoids.
Raw CBD has proven beneficial for those with mild anxiety or insomnia, and it’s usually the product of choice for those looking to benefit from the entire hemp plant and not necessarily just cannabidiol.
