chamomile · honey · soft floral · sweet

Used in skin care for over fifty years for its anti-inflammatory, skin-soothing action.

Chamomile tea’s old reputation as a calming, gut-settling drink is largely this molecule, bisabolol shows real anti-inflammatory action in the gut in early studies.

camphor · pine · musky · earthy · woody

A major component of camphor oil, long used in chest rubs and muscle balms.

In animal studies camphene lowers blood cholesterol and triglycerides, one of a few terpenes with an early lipid-lowering signal. Early work, not a treatment.

black pepper · clove · oak · cinnamon

The only common cannabis terpene that acts on a CB2 receptor, chemically a terpene, functionally a cannabinoid.

That old trick of chewing black peppercorns to ease too-much-THC jitters has real footing, pepper’s caryophyllene and THC meet at the same receptor. Commonly reported to help, harmless to try.

citrus · thyme · oregano · woody · spice-warm

A well-characterized monoterpene from cumin, thyme, and oregano, widely used in flavor and fragrance.

p-Cymene rarely leads a strain, but if citrus-and-herb profiles consistently work for you, it’s one of the quiet fingerprints you’re responding to.

eucalyptus · menthol · camphor · cooling · minty

The primary compound in eucalyptus oil, in cough and respiratory medicines for over a century.

Eucalyptol is one of the few terpenes with real human clinical data. In trials, isolated cineole capsules (the same molecule, not inhaled cannabis) eased airway inflammation in asthma and reduced flare-ups in COPD and bronchitis. The respiratory reputation is earned; the cannabis dose is a separate question.

fennel · pine · herbal · earthy · citrus-bright

A monoterpene alcohol from basil, fennel, and pine, well characterized in perfumery.

A 2014 study found fenchol inhibits TRPA1, a receptor involved in pain signaling, more strongly than camphor or eucalyptol did. Promising and early, and not yet studied in real cannabis use.

rose · geranium · citronella · sweet floral · lemongrass

FDA GRAS-listed and used in perfumery for centuries, the rose note in thousands of products.

Patients managing mood often drift toward floral profiles, geraniol, linalool, bisabolol. The pattern’s consistent enough to notice, even where the mechanism isn’t fully mapped.

pine · woody · rose · resinous · fresh

Named for guaiacum resin, with centuries of traditional use; well characterized in natural-products chemistry.

Nearly every cannabis site lists guaiol’s boiling point as 92°C, and nearly every one is wrong: 92°C is its melting point, copy-pasted into the wrong column for years. Guaiol is a crystalline solid that actually boils near 309°C. It still reaches you from flower, carried out on steam with the lighter terpenes, so the “vape it low or it burns off” advice has the chemistry backward.

hops · sage · ginger · woody

One of the signature terpenes in hops, part of the herbal, bitter character in beer, though myrcene drives most of the aroma.

You will often read that humulene curbs appetite instead of bringing on the munchies. We went looking for the study behind that and could not find one, so we treat it as folklore, not a proven effect. Its anti-inflammatory activity in animal studies is the better-supported story.

lemon peel · sweet orange · grapefruit · juniper

One of the most abundant terpenes in cannabis, and the one most tied to mood-lift in user reports.

A 2024 human trial found vaporized limonene blunted the anxious edge of a high-THC dose, more so at higher amounts, without dulling its other effects. The pathways are still being mapped.

lavender · mint · rosewood · cinnamon

The terpene cannabis shares with lavender, the calm centuries of folk use built a reputation on.

A small human study suggests linalool may lower cortisol under stress. Lab and animal work point to the brain’s GABA calming system as the likely pathway, and much of the calm in studies runs through the sense of smell itself.

earthy · ripe mango · clove · hops

The most abundant terpene in cannabis. Strains people call heavy often run high in myrcene, though the exact 0.5% cutoff is a testing-lab rule of thumb, not a human study.

You may hear that eating a mango before you consume boosts your high through its myrcene. The dose does not add up: a whole mango carries a tiny fraction of the myrcene in a small amount of flower. A fun story, not a real effect.

mint · basil · mango · orchid

A green-floral note across mint, basil, parsley, and hops; a plant defense compound, which is why it’s everywhere in the herb garden.

Ocimene is named after Ocimum, basil. Patients describe its strains as ‘lighter’: less peppery, less sharp, less foggy than the big three.

pine needle · rosemary · basil · cedar

The most abundant terpene in nature; alpha-pinene has real bronchodilator (airway-opening) effects and a clear-headed reputation.

Pinene was long thought to protect short-term memory from high-THC cannabis. A 2025 human trial tested that directly and found it did not. The clear-headed reputation many people describe is real; the memory-protection claim is one we retired.

lilac · apple · nutmeg · tea tree

The defining note in haze strains, found in lilac, apple, nutmeg, and tea tree, which is why it reads ‘perfumed’ rather than weedy.

Despite defining haze, terpinolene is one of the least-studied major terpenes, and the one lab study on record (2013) found mild sedation, not the buzzy lift it’s famous for.
