RSO Expert Guide: Formulation, Studies, & Effects
What is the process used to create Emerald Bay RSO extract and finished products? In the furtherance of full transparency, every conceivable detail is offered in this comprehensive guide to how Emerald Bay RSO is made, what it does, and how it affects your body.
Part 1: Formulation
The effects of RSO begin with formulation, and formulation begins with cannabis selection.
Process for Bulk Oil
We begin by making bulk batches of RSO, which we then use in our syringes and tablets. Emerald Bay Extracts cannabis is sourced from an exclusive community of select family farms located throughout California. Building long-term, trusting relationships with cannabis farmers, we resupply from the same farms year after year, the first step in ensuring consistency and quality in our RSO production process.
Working closely with our supplier farms, we select the exact strains that will most-perfectly fit the specific effects we have in mind. Using our vast database of strain and terpene effects combined with patient feedback, each strain is consciously and deliberately selected to fill a niche in the Emerald Bay Extracts RSO catalog.
Process for Bulk Oil
Primary testing is conducted on-site at the farm by a third-party, state-approved testing lab. This is the first step we take to ensure our finished products have no chance of containing contaminants of any kind. We only transport cannabis to our extraction facility if it has been verified as contaminant-free at the farm.
Upon arrival at our extraction facility, cannabis is first milled or ground down to the specific consistency we’ve scientifically determined works best for RSO extraction. Milled cannabis is then chilled in preparation for extraction, which preserves its full active compound profile. Certain undesirable compounds are also eliminated during this step.
The Emerald Bay Extracts extraction process includes the application of food-grade ethanol chilled to an exact proprietary temperature. Essentially, cannabis and ethanol are combined to create a “tincture.” This tincture is then subjected to a variation of heating, cooling and vacuum-suction processes to filter out cannabinoids, terpenes, and other desirable compounds while leaving behind ethanol and undesirable cannabis substances.
The result is the acidic form of cannabis oil in an exceedingly pure form. Ethanol used during extraction is reclaimed and reused at a future date.
To convert cannabis oil from its acidic to its active, bioavailable form (e.g. THCA to THC, CBDA to CBD), it is heated to a specific temperature determined by its chemical makeup. This allows Emerald Bay Extracts RSO to be consumed orally without any application of additional heat being necessary. Exact, low temperatures are used to provide full activation without damaging terpenes or other delicate cannabis compounds.
To ensure that no contamination has occurred during the extraction process, finished Emerald Bay Extracts RSO is sent to a third-party lab for testing. This process ensures that no residual ethanol has been left behind in our extract, and it also double-checks that no agricultural contaminants somehow made their way through. Testing the finished extract provides us with exact concentrations of cannabinoids, terpenes, flavonoids, and other desirable cannabis compounds.
Process for Tablets
Emerald Bay Extracts RSO is now ready for formulation into finished products. We use a proprietary process involving a combination of heating, cooling, and vacuum pressure to combine this dissolved RSO with microcrystalline cellulose (refined wood pulp), the primary base ingredient in Emerald Bay Extracts RSO Tablets. Ethanol is removed at the end of this process.
We then press the resulting powder using an industrial tablet press machine. With this machine, we can select between 25mg, 50mg, and 100mg options.
Finished, pressed Emerald Bay Extracts tablets are then de-dusted (cleaned), packaged, and sealed in child-resistant jars. Labels are placed on the jars, and they are packaged into case packs.
These case packs are then moved into a quarantine room for a final round of third-party testing. An independent lab visits our facilities, pulls random samples from the batch for testing, and then performs a full round of tests covering potency, pesticides, residual solvents, heavy metals, foreign materials, and mycotoxins.
Only after confirming that finished Emerald Bay Extracts RSO tablets meet or exceed all internal and state regulatory metrics are they removed from the quarantine room and distributed to consumers via our network of partnered dispensaries.
Process for Syringes
The process of making Emerald Bay Extracts RSO syringes begins when our bulk oil is sent in for an additional round of testing, covering potency, residual solvents, and terpene concentrations. Iconic Emerald Bay syringes are then filled with the tested oil.
Syringes are cleaned, capped, and placed in child-resistant packaging. Syringe boxes are labeled, case-packed, and sealed. Sealed case packs are quarantined until tested by a third-party lab.
As is the case with our tablets, random samples are selected from batches of our finished Emerald Bay Extracts syringes, which are then tested for potency, pesticides, residual solvents, heavy metals, foreign materials, and mycotoxins. Only after test results have been received are cleared Emerald Bay Extracts syringes removed from quarantine and made available for sale.
A Note Regarding Biomass Quality & Consistency
We do our best to ensure the utmost standard of product consistency by working with the same farms and selecting the same chemovars year after year. Cannabis is, however, a live plant and subject to some degree of uncontrollable variation between individual organisms.
Factors like growing conditions, geographical location of cultivation, and weather can all affect the outcome of a growing cannabis plant. This may be noted in slight differences between batches of the same Emerald Bay Extracts products.
Recent RSO Peer-Reviewed Studies
As we transition into discussing the ways RSO is used and its effects, it’s worth briefly discussing some of the scientific research that has recently emerged regarding this potent form of cannabis oil:
2022: Cannabis Use in Patients With Cancer: A Clinical Review
This review of available evidence regarding the use of cannabis in cancer care notes that RSO is a “highly potent” form of cannabis extract and confirms that it “does not need to be heated” to achieve these potent effects. RSO is so potent, the authors found, that extra care is warranted when selecting an appropriate dose.
2020: Cancer patients' experiences with medicinal cannabis–related care
This 2020 study surveyed 24 oncology patients and found that eight patients preferred and used RSO instead of other cannabis products. Patients surveyed in the study were highly favorable of RSO overall and its enhanced benefits.
RSO vs. Isolate vs. Distillate
RSO is one of the few examples of genuine full-spectrum cannabis extract. This method is exceedingly gentle of delicate cannabis compounds, leaving the full entourage of terpenes and flavonoids intact.
Full-spectrum extracts like RSO can be further refined to create cannabinoid isolates and distillates. Cannabinoid isolates feature no compounds aside from the desired cannabinoid, and cannabinoid distillates feature dramatically reduced terpene and flavonoid concentrations.
Both extract types fail to offer the benefits offered by full-spectrum extracts like RSO. Additional filtration processes like filtering, carbon scrubbing, and distillation remove many of the beneficial properties of the plant, which is why we only produce full-spectrum RSO.
How RSO Affects Your Body
With a history of use in oncology, RSO is formulated with the intent of being easy on the body. This method of cannabis use is considerably gentler compared to other ingestion methods, including:
RSO vs. Cannabis Smoke
Cannabis smoke is less harmful than tobacco smoke, but it still has detriments, such as tar deposits. RSO does not impact the lungs in any way since it is orally ingested.
RSO vs. Cannabis Vape
Cannabis vapor is believed to have hardly any harm, especially in the form of vaporized cannabis flower. However, there’s still the potential for throat burn, lipoid pneumonia, and other concerns that are not an issue with RSO.
RSO vs. Other Extracts
RSO is a full-spectrum extract, which other types of extracts can (at best) come close to by reintroducing terpenes to the finished product. Having gone through fewer processing stages, RSO is inherently less likely to contain processing contaminants.
RSO vs. Edibles
Many cannabis edibles contain unnecessary or even dangerous ingredients. RSO is fully activated and ready to be added to any food or beverage you choose.
RSO Syringes vs. Tablets
RSO syringes offer more versatility while RSO tablets can be more convenient. With RSO syringes, you can add RSO to any food or beverage, and it also might be easier to take advantage of sublingual administration. RSO tablets, though, are easy to use anytime, anywhere. Choosing an ideal dose is equally easy with both RSO product types.
RSO: Full Profile
Flavor: RSO syringes generally have a nondescript cannabis flavor, but it’s sometimes possible to detect specific terpenes or flavor notes. RSO tablets are largely flavorless.
Aroma: The aroma of RSO tablets — and especially syringes — is usually somewhat noticeable when held to the nose and is much more indicative of the strain’s unique properties than the flavor of RSO.
Texture: Texture varies somewhat between RSO strains, but this type of extract is generally quite viscous and sticky. RSO tablets have a light, chewable texture.
Activation Time: RSO generally activates within 30-60 minutes. Activation time may be improved by holding RSO extract or tablets under the tongue before swallowing, taking advantage of sublingual administration.
Lasts For: The effects of RSO generally last for 3-6 hours when orally ingested.
Side Effects: RSO is a gentle type of cannabis extract that does not commonly cause side effects. When they occur, side effects can include fatigue, paranoia, dry mouth, and digestive discomfort.
RSO in Food
It is perfectly acceptable to add RSO to food. Emerald Bay Extracts RSO has been decarboxylated, meaning it is fully active and does not need to be heated any further. As a result, you can add Emerald Bay Extracts RSO to cold dishes and drinks.
When adding Emerald Bay Extracts RSO to warm or hot food or beverages, just remember that high heat can damage the extract. Consider adding the RSO after warm or hot food has been served or after it has had a chance to cool.
