The question: What are the best plants for extracting and making high-quality CBD-rich oil? Is it marijuana, industrial hemp or both? In cutting through the thick plume of smoke – no pun intended – of the legal issues, the obfuscating nomenclature and the marketing jargon, we’re going to look at what’s really out there for sourcing CBD-rich oil.Where Does CBD Come From?Breaking it DownIn the world of cannabis, there exists two broadly categorized types of plants – hemp and drug. Hemp plants include those grown for fiber and seed oil, while drug plants include euphoric THC-rich plants and non-euphoric CBD-rich plants. The key difference between hemp plants and drug plants has to do with their resin content; most hemp plants are of low resin varieties, while drug plants fall into the category of high resin plants.When answering the question “Where Does CBD Come From?” we must look at where hemp varieties are sourced; industrial hemp varieties are typically sourced from a low resin agricultural crop grown from pedigree seed, with approximately 100 tall, skinny plants per square-meter machine-harvested and manufactured into a multitude of products. Drug plants, meanwhile, are a high-resin horticultural crop typically grown from asexually-reproduced clones, one to two plants per square-meter, hand-harvested, dried, trimmed and cured.Further, federal law originally defined “marihuana” in terms of resin content. Resin was mentioned no less than three times in the definition of “marijuana” encoded in the 1970 Controlled Substances Act, which was lifted word-for-word from the 1937 Marihuana Tax Act. To summarize that document, certain parts of the plant – specifically the “mature stalk” and “sterilized seed” – are exempt from the legal definition of marijuana; but not included in this exemption are the flowers, leaves and sticky resin wherever it is found on the plant.Federal law is actually unequivocal on this point: The resin from any part of the marijuana plant – or any “preparation” made from the resin – is strictly out of bounds. Fiber produced from hemp stalk and oil pressed from hempseed received a legal pass, but not the resin.Where Does CBD Come From?The Resin FactorWhen we’re looking at medicinal and recreational cannabis, it’s the resin that matters because it contains THC and CBD along with dozens of other secondary plant metabolites (essentially other cannabinoids and terpenoids) that augment human brain chemistry and alleviate physiological and psychological distress.The question “Where Does CBD Come From?” can be answered quite literally by looking at the cannabis resin itself – the sticky, gooey cannabis resin is sequestered within the heads of tiny, mushroom-shaped trichomes found mainly on the plant’s odiferous female flowers (buds) and, to a somewhat lesser extent, on the leaves. There are also measly sessile trichomes which dot the stalk of the hemp plant, but these contain hardly any resin at all; non-glandular hairs shaped like tiny inverted commas also cover the plant’s surface.For a myriad of hemp farmers around the globe, CBD oil is considered a co-product or byproduct of industrial hemp grown primary for another purpose. Farmers often sell what is known as unused hemp biomass to a business that wants to extract CBD from the leftovers, with this “dual-use” practice becoming widespread among large-scale hemp growers in Canada, as an example.If you still have questions about how hemp or CBD products can benefit you, we can provide clarity on the subject – just call Healthy Hemp today or click here for all the information you need about this burgeoning market.
