CBD pure hemp oil is extremely popular among users due to its therapeutic and medical benefits. Apart from this, it is versatile because you can easily adjust the dosage, consume it alone or along with edibles and beverages, can be used as topical, etc. Due to these reasons, it is used as the main ingredient in other CBD products. Besides, CBD oils of different colors are available in the market, and this can be confusing for many buyers. The purpose of this article is to investigate various aspects of CBD oil, i.e. its color, quality, and extraction.
How Is CBD Pure Hemp Oil Made?
CBD oils available in the US are made from industrially cultivated hemp plant strains that contain less than 0.3% of THC. This ensures that there are no psychotropic effects upon consuming it orally. Shared below are the details about various factors that affect the quality of hemp CBD oil.
The Growing Conditions Of The Hemp Plant
The hemp plant is efficient in absorbing the compounds found in the soils, and this also includes toxins, heavy metals, etc. Because of this, the plant is also known as a soil remediator. Due to this reason, the quality of the CBD pure hemp oil is very much determined by the growing conditions of the hemp plant. Keep in mind that using chemical fertilizers and pesticides reduces the quality of terpenes and other cannabinoids found in the plant. So, purchase CBD oil made using organically cultivated hemp plant extracts because they give the best full-spectrum extracts.
The Extraction Process Of The CBD Oil
The next major factor that affects the quality of CBD oil is the extraction process, and this also affects its color. Listed below are the different methods of extracting CBD oil.
- Distillation Method: CBD oil extracted by the distillation method has a purity of 95% and above. It completely removes the unwanted plant materials and compounds like the chlorophyll. This gives it a golden color minus the grassy flavor. Most people prefer this and hence, it is the most popular type of CBD oil.
- CO2 Extraction: The carbon dioxide extraction method is used by all reputed CBD oil manufacturers. Here supercritical CO2 is used for extracting cannabinoids like cannabidiol (CBD), and this is because it has the properties of both liquid and gas. This makes it an excellent solvent that gives a high yield. Besides, its solvent effect can be finetuned by adjusting the temperature and pressure. Also, the extract that you get is highly pure because there is no toxic solvent as the residue. Furthermore, CBD oil extracted by the CO2 method has a yellowish-orange or amber color. This is because carbon dioxide extraction does not remove lipids, waxes, and there will be negligible amounts of chlorophyll.
- RSO Method: RSO method of extracting CBD oil aims at preserving the full spectrum of cannabinoids found in the hemp plant. Due to this, there will be small amounts of lipids, waxes, and chlorophyll. This type of hemp CBD oil is dark green, and it has high potency. However, there is the risk of the presence of toxic solvents in the extract because this method uses ethanol, isopropyl alcohol for the extraction process.
- Solvent Extraction: In solvent extraction of CBD oil, butane or hexane are used for extracting the cannabinoids. The CBD oil extracted by this method has a honey color, and it has high CBD content. Besides, these gases are highly flammable, and hence the temperature is kept low during the extraction process. This results in the presence of small amounts of solvent in the extract, which is harmful.
The Filtration Process Of CBD Oil
The filtration process affects the color, quality, and effectiveness of CBD oil. It changes the cannabinoid and terpene profile of the oil, and thereby its effect. Listed below are the different variants of hemp CBD oil.
- RAW Hemp CBD Oil: As the name indicates, raw CBD oil does not undergo any filtration to remove the chlorophyll and other phytocompounds. Because of this, it has a dark green color with a viscous texture. Besides, it tastes bitter and hence not preferred by all. It has the highest concentration of cannabinoids, terpenes, and flavonoids, giving it the most effective entourage effect. Moreover, it has high amounts of the acidic form of cannabidiol (CBD), i.e. cannabidiolic acid (CBDA).
- Decarboxylated CBD Oil: Hemp CBD oil after extraction is heat-treated to increase its CBD concentration, and this process is called decarboxylation. The heat converts cannabidiolic acid (CBDA) into CBD which is more easily available for the endocannabinoid system (ECS) of our body. It is not filtered; hence it has a dark green color, and it tastes bitter.
- Filtered Or Distilled CBD Oil: Different stages of filtering decarboxylated hemp CBD oil gives you filtered or distilled CBD oil. This process removes unwanted plant materials like chlorophyll, most terpenes, lipids, and other phytochemicals. So, the oil has a golden to light golden color, and it is expensive.
We hope that the details shared above will help in your purchase of CBD pure hemp oil for treating the symptoms of your ailments.
