Humboldt Harvest is a specialized hydrocarbon processor running at cryogenic temperatures. We preserve the complete cannabinoid and terpene fingerprint of a single cannabis strain — never re-blended, never reconstructed, formulated for medical applications.
Three letters off in temperature is the difference between a complete spectrum and a damaged one. We choose to be precise.
Inputs are kept strain-pure from receiving through staging. No blending across cultivars, no aggregated lots, no provenance ambiguity.
The solvent is brought to cryogenic temperatures before contact with the biomass. The cold preserves volatile mono-terpenes and acidic cannabinoids that warmer processes drive off.
Every batch is third-party analyzed for full cannabinoid and terpene panel, residual solvents, and contaminants. The chromatogram is published as part of the product record.
Each compound in cannabis has a boiling point — the temperature at which it transitions from preserved to lost. Most extraction methods operate well above several of these thresholds. Cryogenic extraction operates below all of them.
Boiling points sourced from peer-reviewed cannabis chemistry literature. Process temperatures are representative ranges, not specific to any operator. All values approximate.
Acidic precursor to THC. Non-intoxicating in its native form. Retained at cryogenic temperatures; converts above 105°C.
The carboxylated form of CBD. Higher receptor affinity than its neutral counterpart in some pathways. Lost above 120°C.
Often called the "stem cell" cannabinoid — biosynthetic precursor to most others. Easily lost to heat.
Oxidative degradation product of THC, with its own distinct receptor profile. Sensitive to extraction temperatures.
Non-intoxicating, increasingly studied for anti-inflammatory and analgesic activity. Retained at low temperatures.
Structurally similar to THC but with a shorter side chain — and a meaningfully different therapeutic profile.
Terpenes are the most fragile compounds in cannabis. They evaporate first, oxidize easily, and disappear in any process that touches them with heat. They are also the molecules clinical literature increasingly associates with the therapeutic differences between strains.
"We are not in the recreation business. We are not in the lifestyle business. We are in the business of preserving what the plant made, and putting it in the hands of clinicians who already prescribe it."
CDPH Type 7 Manufacturer license with the medical endorsement required to apply for federal pathway. Operating from a permitted facility in Arcata, California.
Federal manufacturer registration application filed via the DEA portal. Operations continue under existing state authority while the agency completes its determination.
Humboldt Harvest does not make therapeutic claims for the diagnosis, treatment, cure, or prevention of any disease. Products are intended for patients whose clinicians have independently determined cannabis to be appropriate for their care. All materials are for licensed-clinician and qualified-patient audiences.
