Populum is a premium CBD brand built on a straightforward promise: full-spectrum hemp oil, third-party tested with publicly available lab reports, shipped to all 50 states. Their tinctures are a daily wellness product, which means the oil has to be consistent batch to batch, Farm Bill compliant at under 0.3% THC, and clean enough that customers taste the carrier oil and natural hemp flavor, not processing residues.
The challenge: full-spectrum without the THC risk
Full-spectrum CBD oil is more valuable than isolate because it preserves the minor cannabinoids (CBG, CBN, CBC) and terpenes that work together in what researchers call the entourage effect. But full-spectrum also means the THC comes along for the ride. Hemp cultivars naturally produce varying levels of THC depending on the growing season, genetics, and even which part of the plant is harvested. A batch that tests at 0.25% THC from one harvest might come in at 0.35% from the next.
For a brand selling nationwide, that 0.3% line is not a guideline. It is the federal legal limit under the 2018 Farm Bill. A single hot batch means the product is legally marijuana, subject to seizure, and a potential criminal liability for the seller. Populum needed an extraction partner that could deliver the full-spectrum profile their customers expect while guaranteeing every batch stays compliant.
The process: CO2 extraction + THC remediation
We start with supercritical CO2 extraction to pull the full cannabinoid and terpene profile from the hemp biomass. CO2 extraction is ideal for a tincture-grade product because it uses no chemical solvents. There is no butane or ethanol residue to remove afterward, no off-flavors introduced by aggressive post-processing, and no degradation of the terpene fraction that gives each cultivar its character.
The raw extract is then winterized to remove plant waxes and lipids, producing a clear, stable oil that mixes cleanly with MCT or hemp seed carrier oil. Winterized extract has a longer shelf life and a smoother mouthfeel in tincture form.
The critical step for Populum is THC remediation. We use chromatography to selectively reduce THC while preserving CBD, minor cannabinoids, and terpenes. Unlike crystallization (which strips everything down to CBD isolate) or degradation (which is non-selective and destroys CBD along with THC), chromatography targets THC specifically. The result is a full-spectrum oil that retains its therapeutic profile and tests consistently under the 0.3% federal limit.
Every batch is third-party lab tested before it leaves our facility. Populum publishes those COAs (Certificates of Analysis) on their website, so their customers can verify the cannabinoid content, terpene profile, and absence of contaminants for the exact batch they purchased.
The result: premium CBD, nationwide compliance
Populum's finished tinctures contain full-spectrum CBD oil that has been CO2-extracted, winterized, and THC-remediated, then blended with a carrier oil at precise potency levels. The oil is clear, shelf-stable, and consistently tests under 0.3% THC, which means Populum can ship to all 50 states without compliance risk.
The brand has built its reputation on transparency: every bottle ships with a QR code linking to the batch's full lab report. That level of traceability starts at the extraction stage. We track each batch from raw biomass intake through extraction, winterization, remediation, and final testing, so the chain of custody is complete from plant to product.
Populum's full product line is available at populum.com.
What this means for your brand
If you are building a CBD brand that needs to ship nationwide, THC remediation is not optional. The same extraction, winterization, and chromatographic remediation process that keeps Populum compliant is available for your product line. We can produce full-spectrum oil at custom potency levels, with full COA documentation, starting at 50 lbs of biomass.
Whether you need bulk oil for your own bottling operation or white-label tinctures ready for retail, we can build a process around your specifications. Contact us to discuss your project.
