Myrcene is in mangoes and hops, limonene in citrus peel, pinene in pine, linalool in lavender. Cannabis is remarkable for combining dozens of them in one flower — not for owning them. This is why strain aromas map so well onto other plants.
Terpenes & Entourage MIXED / UNSETTLEDThe idea that cannabinoids and terpenes work better together has mechanistic support (e.g., caryophyllene at CB2) and wide anecdotal backing, but controlled human trials showing terpene combinations changing THC's effects are essentially absent. Treat it as a hypothesis, not a law.
Terpenes & Entourage STRONG EVIDENCEThe peppery terpene β-caryophyllene — also in black pepper and cloves — directly activates CB2 receptors. It is the best-documented case of a terpene acting like a cannabinoid, demonstrated by Gertsch et al. in 2008.
Terpenes & Entourage MODERATE EVIDENCEChemical analyses repeatedly find that commercial indica/sativa labels poorly predict cannabinoid and terpene content — the actual drivers of effects. Researchers increasingly argue for chemovar (chemical variety) classification instead of folklore taxonomy.
Terpenes & Entourage MIXED / UNSETTLEDMyrcene dominates the terpene profile of many cultivars and is widely blamed for sedation. Controlled human evidence for myrcene alone sedating people is essentially absent; the claim descends from animal data at high doses and industry repetition. Abundant, yes. Proven sedative in humans, no.
Terpenes & Entourage LIMITED EVIDENCEA 2024 Johns Hopkins double-blind trial gave participants THC with vaporized limonene: anxiety and paranoia ratings dropped meaningfully at higher limonene doses. One small trial is not a prescription, but it is the first controlled human evidence for an entourage-style interaction.
Terpenes & Entourage MODERATE EVIDENCETerpenes volatilize at different temperatures — myrcene and pinene low, linalool and caryophyllene higher — so the same flower delivers a different aromatic (and possibly experiential) profile at 170°C than at 210°C. The chemistry of boiling points is solid; claims of tailored effects remain ahead of the evidence.
