Hemp, also referred to as industrial hemp, is a term used to classify varieties of Cannabis grown with minute levels of THC that do not exceed the legal limit of 0.3%. Working with a producer that can control these aspects is an important aspect for compliance and quality of hemp extract products.
At UPLEAFS, we source hemp material from farms that are vertically integrated with our extractors and manufacturers. From feminized seed selection and state-of-the art cloning for consistency, organic growing practices, harvesting, extraction, and final production, we only partner with manufacturers that handle quality control from start to finish. This means we do not use a “middle-man”, which allows us to craft our products. We understand that some brands speak about their production process as if "they" handle all aspects of farming to production; though that may be true for a small handful of brands, it simply isn't true
Our hemp source comes from Colorado, where there is rigorous regulation and verification controlled by the Colorado Department of Agriculture (CDA).
Having strict regulations is important because some sources of hemp derived CBD, mainly outside of the US, may not have regulations in place for testing areas such as contamination and heavy metals.
Note: In each product description, under the “Quality” tab, see additional details for hemp source to confirm hemp origin. While we mainly work with Colorado farms and producers, we may release products where the hemp source may come from a different US region. Always check product descriptions for the most up-to-date information.
Hemp extraction is the process in which the compounds from a hemp plant are separated into a concentrated form that can be consumed or mixed with other ingredients for topical applications. Removing these compounds while keeping the chemical benefits intact is an important process in maintaining extract quality.
There are several methods to extract hemp. Which one is the best is a conflicting topic because all though there are some standard methods for extraction, there have also been developments that are considered proprietary, where the specifics are not shared to the public. So, rating which extraction proves to be the best would require some additional studies and full disclosure from producers. Since this information isn’t always available, your best bet is to always review a products Certificate of Analysis (COA) report to confirm the milligrams of Cannabinoids, THC Levels, and any other tests that it may include.
So, which extract method does UPLEAFS utilize to produce its products? We incorporate several methods based on our desired outcome for product use. Read below for an overview on each of these methods.
Sub-Zero Food Grade Ethanol Extraction
A majority of our products are produced using sub-zero or cold ethanol extraction. Utilizing this type of extraction method allows us to produce a higher quality oil while maintaining the natural terpene profile. Plant material for cold extraction is left intact, which means less damage to beneficial terpenes. The only solvent used in this process is certified organic sugarcane ethyl alcohol with a vacuum type of pressure to separate compounds. In addition to using a food grade solvent, the liquid result is then filtered several times, up to a 1-micron filter, leaving the extract clean and pure. All of our oil drops are created with this type of extraction process; this includes Wellness (Full Spectrum), Wellness Free (Broad Spectrum), and Wellness CBD (Isolate).
Supercritical CO2/Liquid Chromatography Extraction Method
Supercritical CO2 extraction systems are common use for applications such as natural flavorings, essential oils, and hemp. CO2 offers flexibility in the customization of extracts from modifying factors such as pressure temperature and solvent ratios. CO2 requires the hemp plant to be broken down first into a powder-like substance. This method is considered safe and efficient. Though extraction is initially done with CO2, additional processing and purification is required to separate compounds and remove unwanted particles. With the use of liquid chromatography, THC is gently removed to produce a broad spectrum profile, leaving behind non-psychoactive phytocannabinoids, terpenes, and other synergistic compounds.
