Decarboxylated oil is smoother to the taste, but basically tastes like hash, with the floral undertones gone. Heating the plant material or the oil to decarboxylation temperatures will evaporate off most of these smaller aromatic Mono-Terpene and Sesqui-Terpene molecules, before the larger and heavier cannabis Di-Terpenes are affected. Some of these terpenes are highly aromatic alcohols, phenols, ketones, aldehydes, ethers, and esters, which are aromatic because they freely give off molecules at even ambient temperatures. ![]() I will cover that issue under a separate thread on Decarboxylation, so as to not clutter this post.īesides the cannabinoids, which are Di-Terpene alcohols and di-alcohols (diol), there are also other terpenes in cannabis essential oils, which add to its smell, flavor, and medicinal entourage effect. For cannabis concentrates to be orally and topically active, it does require that the THCA and CBDA be converted to THC and CBD, by a heating or drying process. Oil that is to be vaporized, is normally treated differently than oil that is used orally or topically, because it doesn't need to be decarboxylated. That immediately brings to mind the qualifying question, "What do you want to use it for?" We currently use a closed loop system for BHO, and I cover that process on separate threads named The Terpenators, where I will detail building our Mk I through second generation automated systems.īefore we discuss how to extract the essential oils from cannabis, let us talk about the plant material to be used. We've only tried a few processes here at the pharm, and used to cover simple flow through columns, and using a thermos bottle, but now cover only closed loop systems, because of the number of brothers and sisters ignoring my caveats to not extract indoors. If you use a hand microscope, you can easily see when the trichome heads are gone and the stalks look like wet fur. The second extraction will be more sedative and less heady. The first wash will usually extract 75 to 80%, leaving the balance for the second after repacking the column. ![]() Using closed loop extractors, we average slightly more than 20% oil by weight from bud, but as low as 5.7% absolute and as high as 28.1% absolute. Butane produces one of the cleanest extractions, albeit typically at a lower yield than polar alcohol. The answer to that is that because butane is relatively non polar, it doesn’t extract the water solubles like chlorophyll and plant alkaloids. Perhaps the first question is why use a BHO technique to extract the resins, instead of just boiling the material in alcohol to get the greatest amount of extracted material? A concrete or an oleoresin that has been winterized to remove the waxes, lipids, and fats, is known as an Absolute.īutane Honey Oil extraction refers to the method used to extract the essential oils from cannabis, and there are multiple theories on the best way to accomplish this, as well as what material is best to use. It can be extracted from fresh material or from cured material as a Concrete or an Oleoresin. Butane Honey Oil, or BHO, is the essential oil from the cannabis plant, extracted using Butane as a solvent.
