Terpene: Terpenes (/ˈtɜːrpiːn/) are a class of natural products consisting of compounds with the formula (C5H8)n. Comprising more than 30,000 compounds, these unsaturated hydrocarbons are produced predominantly by plants, particularly conifers.[1][2] Terpenes are further classified by the number of carbons: monoterpenes (C10), sesquiterpenes (C15), diterpenes (C20), etc. (Wikipedia) 

Here are some common terpenes and their potential effects:

Beta-caryophyllene: A major ingredient in cloves, rosemary, and hops, beta-caryophyllene could be beneficial for managing symptoms of anxiety and depression.

Beta-pinene: If you’ve strolled through a coniferous forest, you know the smell of beta-pinene, which could also have potentially both anti-depressant and anti-cancer properties.

Humulene: This terpene is found in ginseng, which has long been used in folk medicine for energizing effects.

Limonene: One of the most commonly found terpenes, limonene has distinct citrus notes and may potentially have anti-cancer properties. In mice, it’s been shown  to have anti-anxiety properties.
