We grow Monarda on our farm which yields an essential oil rich in geraniol.
Geraniol occurs in small amounts in geranium, lemon and many other essential oils. It was probably found in geranium for the first time as its name might suggest. Its smell is similar to the smell of roses. It’s often used to imitate taste of many fruits – it’s commonly used in flavouring. Geraniol is a good natural mosquito repellent which at the same time attracts bees. This compound is said to have antioxidating abilities and anti-cancerogenic influence on living organisms.
