Terpene Series: Isopulegol

Isopulegol is a minor terpene found in cannabis, lending a minty, menthol fragrance to the plant. This lesser-known terpene is also found in plants such as mint, eucalyptus, lemongrass, lemon balm, geranium, and parsley. 

Like many aromatic terpenes in cannabis, isopulegol can act as a natural defense against pests, while attracting beneficial pollinators. The scent of isopulegol contributes to the complex and sometimes heady odor profile of cannabis.

Isopulegol is commonly used in cosmetics, soaps, and personal care products, imbuing them with a minty, cooling aroma and sensation. As the chemical precursor to menthol, isopulegol is often used commercially to supplement natural sources of menthol.

The boiling point of isopulegol is 223.77 degrees Celsius.
