Cannabidiol (CBD) products are popular due to their therapeutic and health benefits. One of the most popular cannabidiol products used for medical purposes is CBD oil. This is because of its versatility, and due to this, it is used in other CBD products like edibles, balms, creams, capsules, etc. Besides, its effectiveness depends on its quality, and the presence of contaminants in it adversely affects this. The purpose of this article is to investigate potential contaminants that must be avoided in CBD oil.
What Is CBD Oil?
CBD pure hemp oil is made by dissolving cannabidiol rich hemp flower extracts in carrier oils like MCT, coconut, olive, or grapeseed. This is because, natural CBD is an oil-soluble compound, and mixing it in fat or lipid-rich solvents like oil increases its bioavailability. Cannabidiol hemp extract is made by using solvents like isopropyl alcohol, ethanol, petroleum ether, naphtha, and supercritical CO2. Depending on the solvent used, the taste, color, and quality of the CBD oil vary. In low-quality CBD oils, there will be residue solvent, and this can reduce its quality, as well as its effectiveness. Likewise, the presence of other contaminants has the same effect.
CBD hemp plant extracts are made by dissolving plant parts like flowers in organic chemicals called solvents. The cannabinoids seep into the solvent, and the mixture is then heated to evaporate away from the solvent, leaving the extract. Solvents like CO2 and ethanol are safe, and the former is used for making high-quality CBD oils. Other solvents like hexane, butane, and propane are not safe because they are toxic. Using improper extraction methods can result in the presence of toxic residual solvents in the hemp CBD extract, and consuming CBD oil made using it causes health issues.
Farmers use pesticides for preventing, destroying, or controlling pests that destroy crops or plants. But, using them for cultivating hemp plants reduces the quality of CBD hemp extracts used for making CBD oil. So, in federally approved farms, hemp plants must be cultivated organically without using pesticides or chemical fertilizers. Not only that, the Environmental Protection Agency (EPA) ensures this by regularly checking soil samples from these farms for the presence of these contaminants.
Heavy metals are naturally found in soil and water, and some of them are safe, while others are toxic. For example, zinc and iron are essential micronutrients for our body, while mercury, cadmium, and arsenic are toxic. Hemp plants easily absorb this from the soil, and consuming CBD oil containing these metals is bad for health. Due to this, it is important to use CBD oil made from organically cultivated hemp plants.
These are some of the important points that you must know about potential contaminants in CBD pure hemp oil.
