Terpenes are the aromatic compounds behind a cultivar's smell and, plausibly, part of how it feels. The aroma chemistry is settled. The effect evidence mostly is not, and every card says which.

Showing all 10 terpenes.
Animal studies have looked at sedation and muscle relaxation. Myrcene is the most common terpene in modern cultivars, and the varieties patients describe as heavy or couch-locking tend to be the myrcene-rich ones.

When a product leaves you sleepier than you planned, check the myrcene number on the lab sheet before anything else.
Animal models show mood-lifting and anti-anxiety signals, and a few small human aromatherapy studies point the same way. It has also been studied for acid reflux, which is not much help to a cannabis patient.

Two products at the same THC number can feel very different, and the rest of the profile is often the reason. Patients tend to describe limonene-forward products as brighter.
This is the only terpene shown to bind a cannabinoid receptor directly, CB2, the receptor concentrated in immune tissue. Animal work on inflammation and pain has been consistent enough that it is the most pharmacologically interesting compound on this page.

If pain or inflammation is the goal and two lab sheets otherwise look alike, the caryophyllene number is a reasonable tiebreaker.
Older human work looked at opening the airways. In animal studies, the short-term memory interference caused by THC looks smaller when pinene is present.
At the counter
The folk claim that piney varieties leave the head clearer points the same direction as the animal data. That is as far as an honest sentence can go.
Calming and sedative effects, with a longer research trail than most terpenes because lavender itself has been through small human anxiety trials.
At the counter
If evening anxiety is the problem you are trying to solve, this is the terpene to look for on the lab sheet.
Rodent work finds it mildly sedating, even though in cannabis it is known for showing up in energetic daytime varieties. The literature and the folklore genuinely disagree on this one.
At the counter
A good reminder that the whole profile matters more than any single terpene: terpinolene-dominant cultivars are usually high in THC and low in myrcene as well.
Animal models show anti-inflammatory activity and appetite suppression, the reverse of the appetite push most cannabis produces.

Worth knowing mainly so the word on a lab sheet does not read as noise.
Antifungal and antiviral properties in test-tube work. There is very little on effects in people.
At the counter
Treat it as an aroma note. If a budtender credits an effect to ocimene in particular, be skeptical.
Skin-soothing and anti-irritation effects backed by real cosmetic dermatology literature, which is why it turns up in so many face creams at the pharmacy.
At the counter
More relevant to topicals than to anything inhaled or swallowed.
Rodent work shows sedative signals. It also helps compounds pass through skin, which is why it appears in transdermal patch research.
At the counter
On a patch ingredient list it is there to help delivery, not to add an effect.
No cultivar in the reference lists it as dominant.
