Phytol — the cannabis terpene in depth
Phytol is a sesquiterpene with molecular formula C₂₀H₄₀O and a boiling point of 204 °C. In cannabis, typical levels are 0.01–0.2 % dry weight. Outside the plant it is found in green tea, jasmine, chlorophyll degradation products, spinach, sunflower. Within the cannabis aroma landscape, Phytol is an important contributor, dominant in chemovars such as Sour Diesel, OG Kush, Cheese, Blue Dream. It shapes overall character via the entourage effect.
green tea, grassy, mildly floral, balsamic — Phytol is a sesquiterpene that defines its own chemovar signature.
Aroma
Profile: green tea, grassy, mildly floral, balsamic. Perceivable from ~0.3 % dry weight. With limonene: citrus-fresh; with myrcene: earthy-spicy.
Occurrence
In cannabis, Phytol is produced in the trichomes of the flower. It is quantified by GC-MS and appears on modern COAs. Strains rich in Phytol include Sour Diesel, OG Kush, Cheese, Blue Dream. It usually co-occurs with myrcene and caryophyllene — the exact ratios determine the sensorial nuance.
Effect
Preclinically linked to anxiolytic and calming effects via the GABA system. Evidence: Costa et al. 2014 (Pharmacol Biochem Behav). Legal note: in Switzerland, cannabis with ≥ 1 % THC is a narcotic. CBD flowers below 1 % THC are legal; medical cannabis requires authorisation. Effect descriptions are not therapeutic claims.
