Terpene Series: Geraniol

Geraniol is a monoterpenoid and alcohol that is a primary component of citronella oil, rose oil, and palmarosa oil. Geraniol occurs naturally in the essential oils of geranium and lemon as well as numerous fruits, flowers, and vegetables.

Produced by the scent glands of honeybees, geraniol serves as a mark of nectar-bearing flowers and a guide for the bees to locate the entrance to their hives. The fragrance of geraniol has little to do with honey, however, and is best described as having a rose-like aroma. Because of its floral aroma, geraniol typically centres around perfumes and other scents. Additionally, the geraniol terpene is often used as a flavoring agent for many fruit-based products, such as the orange flavour in a cough drop or the watermelon flavour of a hard candy.
If you have a sweet tooth, then you may have consumed a good amount of geraniol, as the terpene is often used to enhance the flavour of ice cream and candy. Outside of the kitchen, you may have some products containing geraniol in your medicine cabinet, such as body lotion and soap. Finally, along with citronellol, the geraniol terpene is a key component of citronella oil, which wards off mosquitos, so you may have these terpenes sitting on your patio in a candle.

Fun Fact: Geraniol bears a connection to other terpenes present in cannabis, including myrcene and ocimene. These two terpenes are formed by the dehydration and isomerization of geraniol.
The boiling point of Geraniol is 230 Degrees Celsius
