Valencene received its name from Valencia oranges, which have an especially sweet citrus flavor. The terpene is also present in grapefruits and tangerines. Manufacturers often use valencene to give a citrus aroma to cleaning products. Valencene is renowned for its ability to repel insects, reduce inflammation, and fight skin cancer.
