When it comes to the hemp oils extracted from the cannabis or hemp plants there are a number of differing types to be aware of, each with differing advantages and containing differing chemical make ups. You might’ve heard different terms like ‘full spectrum’, ‘isolate’ or ‘whole plant’ but what do each of these mean? Do I need to take note of anything particular about these differing oil types? The answers to these questions are what we’ll be exploring as part of this article, examining what full spectrum and isolate hemp oils are and why their differences matter. You would’ve already seen both types of oil on sale or around the internet so its important to understand their particular characteristics and where the place of each is.
What is full spectrum and isolate hemp extracts?
When you see the term ‘full spectrum’ it really just means some of the plant matter that was processed to refine the extract down to an oil has been retained in the final tincture – it still contains some of the ‘raw’ plant that has a high quantity of potentially useful chemicals like phytocannabinoids and chlorophyll. It may also contain other naturally occurring compounds like phytochemicals. These are all removed when an isolated hemp oil is created, retaining only the pure CBD or THC extract. Final composition and chemicals retained in the end product depends strongly on what refinement and extraction methods were used, which will leave more or less plant matter or ‘whole plant’ elements remaining in the product.
These organic plant chemicals contain molecules of various substances like terpenes – pungent, scent compounds originating in many plants like fruits and flowers. They’re also able to pair with and enhance the effects of cannabinoids like CBG and CBD..
The entourage effect in hemp oil
One of the biggest arguments for full spectrum extracts over isolate oils is what’s known as the entourage effect. This is a phenomenon purported by many scientists which states that the effects of the key compound (cannabidiol) becomes enhanced due to supporting nutrients and compounds like antioxidants, omega 3 and phytochemicals present in hemp. These supplementary compounds help to strengthen and bring out the effects of the plant therapeutically for better overall results. Essentially the different chemicals work better in combination than separately, resulting in better outcomes for sleep, mood and bodily function.
Research studies have been showing that full spectrum hemp oil has been delivering better results and help with symptoms than isolates due to containing supplementary compounds like phytochemicals. Cannabis oil rich in terpenes and flavonoids are able to enhance and magnify the existing effects of full spectrum hemp oil. An example is the terpene called pinene which is known as being able to help with reducing the cognitive reduction caused by THC. Other similar terpenes (organic scent compounds) like myrcene, pinene and caryophyllene are also known to pair well with full spectrum hemp oil and assist in providing anti anxiety and anti inflammatory effects. More research is needed to hone in on the exact interactions between terpenes, flavonoids and cannabinoid compounds.
Compounds in the cannabis plant
There are close to 500 chemicals in the cannabis plant including CBD and THC but not all are relevant and useful. Taking a full spectrum oil means you take in cannabinoids outside of just CBD – which may include CBA, CBG, CBN and other trace compounds like terpenes, chlorophyll, flavonoids and more which all help in improving health.
Full spectrum extracts are produced in labs, usually via CO2 extraction or a solvent extraction method. Full spectrum hemp oil usually has low or no THC content (below 0.3%).
A product range of extracts that contain high levels of cannabidiol, CBD concentrates are able to be transformed into many different formats including sublingual, inhalers, edibles, capsules and more. Typically they will contain from 50 to 100% cannabidiol, making them very high dosage and only requiring small amounts usually.
Whole Plant Full Spectrum Hemp Oil
Usually whole plant extracts are developed when heat and solvents aren’t used when the plant oil is being extracted. The plant product stays partially intact through this process, enabling some of the key nutrients and phytocompounds to remain in the end product. It also allows more cannabinoids to be included in the final extract with varying benefits, such as CBG and CBA. The final product will also contain valuable compounds like chlorophyll, flavonoids and terpenes. As some plant matter remains and is not removed by heat or solvents, you’re able to get the ‘full spectrum’ of plant compounds contained in hemp without removing key phytonutrients.
What is phyto-cannabinoid rich Hemp Oil?
To answer this we first need to understand what phytocannabinoids are. Phytocannabinoids are those cannabinoids which are inert and don’t activate the endocannabinoid system. They’re produced in the buds of the cannabis plant and are beneficial to the body due to antioxidant content. PCR or phyto-cannabinoid rich hemp oil is a product which contains a high level of phytocannabinoids compared to standard hemp oil. Typically oils like full spectrum hemp oil already contain a high amount of phyto cannabinoids. PCR is separate from the typical CBD concentrates you may have heard of which fall under the banner of isolate, full spectrum or broad spectrum hemp oils.
CBD Oil Isolates
The real difference between isolates, full spectrum and broad spectrum oils are just the chemical contents of each and their potency. Full Spectrum contains more plant compounds that are raw and haven’t been removed in the extraction process – it also doesn’t necessarily contain CBD. Isolates contain only the pure CBD crystal which is 99% CBD content. Full spectrum hemp oils or broad spectrum also typically contain CBG and CBA. Isolates are made in the same method as other formats of hemp oil, however it is chilled after being extracted via winterisation, that utterly removes any other chemical remaining in the mixture apart from CBD. This chemical processing results in a crystal white powder form of CBD which can then be transferred into items like sublingual strips. Isolates are usually lower price than their full spectrum counterparts but can miss much of the plant compounds which similarly carry benefits to the brain and body as CBD. These help to draw out and trigger the entourage effect and enhance the overall therapeutic application of the hemp extract.
Full Spectrum Hemp Oil
These oils are very different to isolate products, as they don’t go through chilling and winterisation to remove the plant compounds and matter from the end product that provide plant nutrients and phytocompounds. There are also critical fatty acids and terpene plant compounds in full spectrum oils which may contribute to the entourage effect. Full spectrum oils still typically remove THC from the extract due to its psychoactive risks. Thus they also won’t get you high but are able to provide a full spectrum of hemp oil’s benefits to the body and drive anti-inflammatory effects. This has been demonstrated from studies in the early 2000s and indicates the benefits obtained from full spectrum hemp oil are enhanced by other compounds. Broad spectrum is slightly different again, where THC is completely removed from the final extract.
These three types of oils usually are contained within a carrier oil which holds the substrate compound in it and is more palatable. When combined with a carrier the final mixed product is known as a tincture, which is usually a liquid mix. You might see full spectrum hemp oil be called a tincture or straight oil – tinctures contain carriers like coconut oil or MCT oil. Because of the long chain fatty acids and omegas in the carriers, the overall nutrition and health profile of hemp oil is enhanced. Their use and lifespan also increases as a tincture, making cooking and combination in drinks possible for each user. Tinctures have a longer lifespan and carry the product for greater periods.
Final Thoughts – Full Spectrum vs Isolate
Hemp oils and concentrate varieties come in a range of differing oil types, styles, strengths and final product makeup. We’ve looked at how isolates, full spectrum and broad spectrum hemp oils compare in their makeup and characteristics, what to look for in each and how the numerous additional nutrients like phytocompounds and flavonoids in full spectrum oils drive benefits via the entourage effect. We’ve heard how decarboxylated products from CO2 extraction can avoid the solvent process and how isolates versus full spectrum hemp oils are crafted. We also briefly looked at PCR or phyto-cannabinoid compound rich hemp oils. We also looked at how broad spectrum oils differ from full spectrum oils and how products from tinctures to pure extracts can be taken as oil, sublingually applied or inhaled even when in isolated form.
