Everything you need to know about 'Full Spectrum Oil' - FSO
Full Spectrum Oil (FSO) is the highest standard (premium) extract in the medicinal cannabis industry. It is the most pure, balanced, beneficial and the most expensive because of the process and costs of producing the extract. In this article we take a deep dive into why FSO is the premium extract for cannabis products and how it is made.
1. Why is FSO the 'Premium of Cannabis Extracts'
Cannabis and the different species of cannabis produce a wide variety of chemicals. These chemicals are found in the trichomes which grow in the cannabis flower. These chemicals can be put into 3 categories: Flavonoids, Terpenes and Cannabinoids. Most cannabis oils sold for medicinal benefit in South Africa are made from a select few cannabinoids only. ‘FSO’ extract has all three categories in a balanced laboratory tested ratio ideal for maximised medicinal / therapeutic use. These 3 categories when applied together give cannabis the most beneficial effect, often called the ‘entourage effect’. This is the effect of the full spectrum of chemicals in the plant. This way the effect of FSO extract is amplified without an increase in negative side effects. It contains all the cannabinoids available in the plant with CBD being the main element for its medicinal properties. Our FSO will not make you high, but you will feel the entourage effect as it works its magic.
Flavonoids: They are responsible for the different tastes which are often very bitter and is natures mechanism of preventing the plant being consumed by insects. Certain flavonoids in cannabis, such as cannflavin A and cannflavin B have anti-inflammatory properties, antioxidant effects, and neuroprotective effects. There is some evidence that it may also have potential anti-cancer properties as certain flavonoids may inhibit specific pathways involved in cancer development. Flavonoids are still in the early research phase but it is evident that they have therapeutic properties that are still being explored.
Terpenes: Terpenes are what give cannabis its distinct smell. Some people that smoke cannabis and who are experienced cannabis users can pickup around 8 terpene profiles. Although there are more than 100 terpenes that exist in cannabis varieties, they are found in trace amounts and do not have medicinal benefit in such small quantities. There are three terpenes backed by university research that we focus on to give medicinal benefit. They are Mycrene, Caryophyllene and Limonene.
- Myrcene: Research indicates myrcene may effectively reduce inflammation associated with osteoarthritis. Moreover, the terpene seemed to play a role in preventing the breakdown of cartilage cells, slowing down the progression of osteoarthritis, and decreasing the production of specific inflammatory cells in the body. Myrcene holds promise for potential future use in alleviating inflammatory diseases and their associated symptoms.
- Caryophyllene: The therapeutic potential of caryophyllene indicates its promise in alleviating symptoms associated with diverse conditions such as colitis, diabetes, cerebral ischemia, anxiety and depression, liver fibrosis, and Alzheimer-like diseases. Ongoing research suggests that harnessing caryophyllene’s activity at the CB2 receptor could be a valuable approach for treating conditions accompanied by inflammatory symptoms. Caryophyllene is the only known terpene that can bind to the CB2 receptor in the endogenous cannabinoid system.
- Limonene: Research indicates that limonene may alter the behaviour of specific immune cells in the body, potentially providing protection against various disorders. Limonene has been observed to enhance the production of antibody-producing cells in the spleen and bone marrow, crucial components used by the immune system to identify and neutralise pathogenic bacteria and viruses.
Cannabinoids: These chemical compounds are what give cannabis its major medicinal effects. There are over 70 cannabinoids but the most common three spoken about are THC, CBD and CBN. THC is the main psychoactive chemical which is what makes you high. CBD is the most researched medicinal compound which has a major impact on the immune system, inflammation, pain, sleep and general well being. Some cannabis oils or extracts are called isolates which means they take only one chemical compound and discard the rest. This is usually done because it is the cheapest and simplest way of making cannabis oil. However, when we want the maximum medicinal benefit all cannabinoids have a roll to play, as long as we understand these roles. We therefore study all the cannabinoids to workout what cannabinoids we want, and what percentage of each cannabinoid is ideal for maximum medicinal benefit with minimal side effects. Depending on the strain of the cannabis plant, the chemical ratio of these compounds differ. Some plants are high in CBD with very low amounts of other cannabinoids such as CBN or THC. Some plants are high in THC and low in CBD. Because of this we grow a variety of plants with different cannabinoid ratios so that we can blend our own formula for a maximum medicinal cannabinoid profile. We follow a model from the USA that is precise, hard to replicate and hard to compete with regards to quality. This has helped us to become professionals in our industry and deliver consistent premium cannabis products that are above South African standard regulations.
2. How is our FSO made?
We grow 4 different varieties of medicinal grade plants to make our specific formula with the seeds coming from the USA and the Netherlands. Each year we grow a new variety for testing purposes so that we might be able to find a single plant that has the cannabinoid profile we want to be close to our formula, and can grow in the climate conditions we experience in South Africa.
This harvest process: We do an early harvest of 1/4 of our plants because we find some chemicals to be much stronger than when the plant is mature. These chemicals in mature plants are mostly in trace amounts. We then do our general harvest when our cannabis flowers are perfectly mature (ripe) and we know the CBD cannabinoid is at its maximum level. We know they ripe after we inspect the trichomes through magnification. We take 2/4 of the mature flower leaving 1/4 to over mature as again the chemicals change and we have access to these chemicals in greater volumes.
1/4 of the cannabis is harvested early
2/4 of the plant is harvested when plants are mature (ripe)
1/4 of the plant is harvested late
The drying process: Most of the cannabis is hung to dry for around 8 days which leaves the moisture content in the flower to around 65% which is good for trimming. We then trim the leaves off the flower using special trimming scissors and equipment because it is the flower of the cannabis that is used. Most people think that it is the cannabis leaves themselves that have the wanted chemicals but this is not true. After we have trimmed the flower, it gets placed in special bags for curing. This just means the moisture content is spread evenly and these bags keep the moisture content to 62%. After 8 weeks in the bag the cannabis is cured and can be stored for a decent amount of time. Some of the cannabis is not dried or cured at all but is first trimmed then gets frozen immediately. This is because during drying and curing certain chemicals are released which we want in our FSO but in small amounts, so we get this from our freshly frozen cannabis.
The decarboxylation process: We only decarb 75% of our cannabis that has been dried and cured in the bags. All cannabis cannabinoids like CBD and THC are still in there acidic state. So they are actually before decarboxylation called CBD-A and THC-A and we need to activate the cannabinoids to turn them into CBD and THC. We do this by using an oven as heat does this conversion for us. We also want some of the cannabis in its acidic state as CBD-A and CBD both have medicinal effects but work differently. It is also important to note that heating the cannabis burns off the terpenes we need to get the entourage effect, that is why we don’t decarb 25% of our cured cannabis and don’t decarb our freshly frozen cannabis.
Extracting process of the chemicals: We want to only extract the oils from the trichomes in the flower, and not any of the plant matter such as water, chlorophyll, or certain proteins from the stems and sticks in the flower. We want the most pure oil. To do this we use a laboratory grade Acetone. This is different than industrial acetone or nail polish remover. What we use is the best chemical for oil extraction as it is a polar and non polar solvent. For example, this means it can extract water, but if frozen it leaves the water behind. Therefore all our cannabis now gets frozen as well as the acetone because we only want to extract the oil and not the water, chlorophyll or proteins. Before the cannabis is frozen it is grinded up and put into larger jars so that there is more surface area to come in contact with the acetone. Once the cannabis is completely frozen we run the cold acetone over the frozen cannabis and this way we get the purest extract of flavonoids, terpenes, and cannabinoids. We then filter the acetone now holding our desired chemicals. We use specialised laboratory equipment to boil off the acetone in a safe environment as acetone is extremely volatile and flammable. It is highly dangerous and not recommended to do this at home unless you have the proper equipment and knowledge. Once the acetone is completely removed what we have left is pure cannabis oil. We do not mix all our oil together just yet. It is still separated from the cannabis oil made from the freshly frozen cannabis, the early harvested cannabis, the mature cannabis, the cannabis that was left for a late harvest and also the cannabis that was not decarbed. Now don’t forget that we have 4 different varieties of cannabis plants and we do this process for each variety.
Blending our FSO formula together: We end up with 5 different oils from each variety of cannabis plant. This means we have 20 different oils that get sent to a professional lab testing facility. They test for the following:
- Potency of cannabinoid profile
- Terpene analysis
- Solvent analysis
- Microbial analysis
- Heavy Metals analysis
- Mycotoxins
Once we receive the lab report for each sample and it passes our regulation checklist, we can now blend our oils together to get our exact formula that is the most benefit for medicinal purposes. Our Full Spectrum Oil is now complete and we send in a sample to the labs to confirm our oil blend is accurate to our calculations. If it is accurate we now can use that oil in our products.
As you can see, a lot of work goes into our ‘Premium FSO’ and it is why our products are of the highest quality and are more expensive than the lady who makes cannabis oil down the road in her kitchen.
