Camphene
Both go cold in the sinuses and both get called medicinal. Camphene is the damp, woody one; eucalyptol is clean mint.

Eucalyptol is the cold you feel at the back of your nose from a eucalyptus leaf or a strong chest rub. Tea tree, bay, sage and cardamom carry it too. In cannabis it's uncommon and unmistakable — a cooling note that reads almost like menthol.
About Eucalyptol
It's the sharpener. Eucalyptol runs to the alert, clear end of things, and it's the compound behind eucalyptus's long use for opening up breathing. In a strain it tends to cut through the heavier terpenes rather than blend into them.
At 176°C / 349°F eucalyptol survives a dry better than most, which is lucky, because there is rarely much of it to begin with. It's an accent, not a headline. Lose a third of it to a warm room and you don't get a milder cool note — you get none.

Commonly Confused With
Pinene
Pinene is resin, eucalyptol is mint. They share the impression of freshness and nothing else.

Both carry spice, but eucalyptol's is cooling and caryophyllene's is hot. One opens your sinuses, the other bites.
