Pure Natural Hemp Oil – An In-Depth Look at Organic Farming & Extraction
Cannbidiol, or CBD, is one of the cannabinoid compounds found in marijuana and hemp plants. Most CBD oil products are manufactured from cannabidiol derived from the hemp plant. That is because hemp contains a minimal amount of THC, the natural compound that gives marijuana its psychoactive properties. As per federal law, a CBD product should contain no more than 0.3% THC to be sold and consumed legally in the US. This nominal amount of THC makes a CBD product exempt from being a controlled substance under federal law.
Many kinds of research and studies are being conducted to conclude how CBD can be beneficial for different purposes. Below is a quick look at how CBD hemp oil is extracted. This information will come handy when you buy CBD products online.
Organic Farming of Hemp
Organic CBD product manufacturers grow natural strains of phytocannabinoid-rich hemp in nutrient-rich soil. They follow strict state guidelines and federal laws and many use only organic methods for the farming and cultivation of hemp. Many approved high-tech processes are involved in the farming and cultivation to ensure that the quality of the hemp strain improves naturally. Certified organic hemp farming uses no pesticides or chemicals. This in turn benefits organic CBD product users and certifies that all the CBD products are safe to use, regulated, and have the best potency and consistency.
After the harvest of the hemp plants, they are dried and stored in a controlled environment. The plants are then processed as required and ground to a coarse powder state using a pulverizing machine. When the processing is done, the ground hemp goes through the extraction and purification process. Here, the unnecessary compounds from the hemp plant are discarded and the healthy phytocannabinoids and flavonoids are preserved. This gives you the best-quality pure hemp oil that is rich in its beneficial properties.
Extraction of Hemp Oil
There are three main ways to extract CBD oil – using CO2, steam distillation, and hydrocarbons or natural solvents. The CO2 extraction process is found to be the most effective of all and produces high concentrations of CBD in the resulting oil. It is a complex and expensive process, but it produces top-quality yields. The steam distillation method employs a meticulous process to separate the CBD oil from the plant material. However, it requires large amounts of hemp plants to produce the required amount of CBD oil. Besides, it is also seen that the steam distillation method produces low concentration CBD when compared to the CO2 extraction technique.
The third method involves the use of hydrocarbons or natural solvents to extract hemp oil. While hydrocarbons, such as butane, propane, isopropyl, or alcohol, can be effective for the extraction, these can also pull the chlorophyll from the plant along with CBD. This makes the final product a bit more bitter. That is why food-grade ethanol, olive oil, and other natural solvents are preferred in this method. Natural solvent extraction makes certain that the final product is safe for edible purposes. However, using olive oil also does not give as concentrated hemp oil as the CO2 extraction technique does.
After the extraction stage, the CBD hemp oil is sent for purification so that even the smallest of THC traces can be eliminated. This is to make sure that the final CBD product will not give the user a high when consumed. This process also removes any lingering unwanted compounds from pure hemp oil, such as chlorophyll, lipids, and other plant pigments. After the purification stage, the manufacturer sends the CBD oil for in-house lab testing so that they can certify that the final product has the quality and potency that the label says.
Note that there are various types of CBD products, which contain different forms of hemp extract. Therefore, the refining and purification process may vary as per the type of CBD extract. For instance, full-spectrum CBD products will contain all of the natural cannabinoid compounds found in the hemp plant, including traces of THC. On the other hand, broad-spectrum CBD products will have all the natural cannabinoid compounds of hemp, but no THC.
Broad-spectrum CBD oil is manufactured by further processing full-spectrum hemp extracts. This includes using a specialized process called liquid chromatography, which selectively removes the traces of THC from hemp oil at low temperatures. Then there are CBD isolate products, which contain a pure concentration of CBD only. It is created by cooling and purifying the hemp extract into a crystalline isolate form. This is then refined into a white flavorless powder. CBD isolate products are recommended to those users who need regular high doses of CBD.
