Reference Data
This is the terpene-to-effect weighting table behind Matchleaf's deterministic scoring engine — the same data every strain match is computed from. For each of the 10 effect categories, terpenes are classified as primarily driving the effect, supporting it, or mechanistically working against it. These are preclinical associations from terpene pharmacology research, not medical claims.
primaryThe strongest positive contributor — this terpene's presence is the main mechanistic driver of the effect.
supportingA smaller positive contributor — reinforces the effect alongside a primary terpene, but doesn't drive it alone.
suppressesA negative contributor — this terpene's presence mechanistically works against the effect, pulling the score down rather than up.
These are relative modeling weights inside Matchleaf's engine, not measurements of potency or concentration — a strain's actual score also depends on how much of each terpene it contains relative to the others.

Myrcene and Linalool are the primary terpenes mechanistically associated with sleep in Matchleaf's scoring model, with Nerolidol and Terpineol contributing supporting sedative associations. This is a preclinical terpene association, not a medical claim.
Myrcene is modeled as working against focus — its sedating mechanistic profile counteracts the alertness terpenes (Pinene and Eucalyptol) that primarily drive the focus association.
They describe the direction and strength of a terpene's mechanistic contribution in Matchleaf's deterministic scoring engine: a "primary" terpene contributes the strongest positive weight toward an effect, a "supporting" terpene contributes a smaller positive weight, and a terpene that "suppresses" an effect contributes a negative weight — mechanistically working against it. These are relative modeling weights, not measures of potency or concentration.
Myrcene appears in Matchleaf's model for 8 of the 10 effect categories — more than any other terpene — reflecting its broad mechanistic relevance across the primary/supporting/suppresses relationships in the matrix below.
No. Every terpene-effect relationship shown here is a preclinical, mechanistic association drawn from terpene pharmacology research — not a medical claim, and not a guarantee of individual effect. Matchleaf is informational only.
This matrix is the general model: which terpenes are associated with which effects, independent of any one strain. A strain's profile page (matchleaf.app/strains/[name]) applies this same model to that strain's actual terpene composition to produce its specific effect scores.
