Used for over 2,500 years, cannabidiol (CBD)—a non-psychoactive cannabinoid from cannabis and hemp—stands apart from THC, enabling its legal trade. In recent years, CBD products have surged in popularity across various forms. Backed by scientific recognition for therapeutic uses, CBD is increasingly embraced for enhancing everyday well-being. Today, you can access it legally to support aspects of daily life. Here's an expert overview of CBD.
Cannabidiol is a natural, non-psychoactive compound abundant in hemp from the cannabis plant. Clinical evidence supports its role in treating conditions like epilepsy, anxiety, and schizophrenia. Numerous cases also highlight CBD oil and products aiding people—and pets—with diverse health issues.
CBD oil is produced by extracting cannabidiol from cannabis or hemp, yielding high-CBD concentrations alongside varying levels of other cannabinoids and plant compounds. The broad use of 'CBD' can cause confusion, as profiles differ. Available as:
Key types include:
Unlike flavonoids and terpenes, cannabidiol is unique to the cannabis plant, encompassing both hemp and marijuana varieties. Though from the same species, their cannabinoid and terpene profiles vary significantly.
These differences influence CBD oil profiles. Hemp naturally contains minimal THC—typically 0.035% or less—making it ideal for THC-avoiders. Hemp's unique compound spectrum may offer distinct therapeutic benefits.
Cannabis yields broader cannabinoids, including higher THC. Previously, large hemp crops were needed for CBD oil; now, PCR hemp enables efficient, high-yield cultivation on smaller scales.
As the CBD market expands, CO2 (carbon dioxide) extraction has emerged as the premier, safest method—despite higher costs—producing potent, chlorophyll-free oil. It includes supercritical, subcritical, and mid-critical variants.
CO2 starts as a gas. Supercritical CO2 forms above 31.1°C and 1071 psi, blending gas and liquid properties. Closed-loop extractors with three chambers manage this: plant material loads into one, CO2 converts to supercritical form, extracts cannabinoids, trichomes, and terpenes, then separates in the final chamber. Oil collects, CO2 recycles, and contaminants like bacteria and mold are eliminated.
Solvent methods use ethanol or isopropyl alcohol—cheap but hazardous due to flammability. They often strip beneficial waxes and chlorophyll, imparting bitterness; filtering reduces potency.
Post-harvest, solvents soak or pass through plant material, extracting cannabinoids. Evaporation leaves oil, but residues can persist, including harmful petroleum traces per some studies—posing health risks.
