Full Spectrum CBD — the entourage effect explained
Full spectrum CBD carries the plant's full active profile — not just CBD. Why it often feels stronger than isolate and what to look for when buying.
Full spectrum CBD contains CBD plus other cannabinoids (CBG, CBN, CBC, <1% THC), terpenes and flavonoids. Together they create the entourage effect — total action greater than the sum of the parts. Broad spectrum = no THC. Isolate = pure CBD. Studies (Russo 2011) back the entourage hypothesis.
What's inside full spectrum
A quality full-spectrum extract from Swiss indoor hemp typically contains 5–25% CBD, 0.5–5% CBG (mother cannabinoid), traces of CBN (relaxing) and CBC (anti-inflammatory), and <1% THC.
Plus 1–5% terpenes: myrcene (sedative), limonene (mood lift), pinene (clarity), caryophyllene (anti-inflammatory, CB2 agonist), linalool (calming). Plus plant flavonoids.
The entourage effect
Concept from Mechoulam and Ben-Shabat (1998), popularised by Ethan Russo in 2011: cannabinoids and terpenes work synergistically. The mix is therapeutically stronger than isolates.
Examples: myrcene prolongs and deepens sedation. Caryophyllene activates CB2 — anti-inflammatory. Linalool and CBD reinforce each other on stress. CBC potentiates CBD's analgesia.
Full vs broad spectrum vs isolate
Full spectrum: everything, including <1% THC. Strongest entourage effect. Theoretically detectable in highly sensitive drug tests.
Broad spectrum: same richness minus THC. Weaker entourage, no test risk.
FAQ
Is full spectrum stronger than isolate?
At equal CBD, full spectrum often feels stronger — thanks to the entourage effect. Studies point the same way.
Does full spectrum CBD get you high?
No. <1% THC is too low to cause a high.
Can full spectrum trigger a positive drug test?
Theoretically yes at very high daily doses. CBD isolate eliminates the risk.
How do I spot real full spectrum?
Lab certificate (COA) with full cannabinoid + terpene profile. Amber colour, slightly earthy taste.
