The name phellandrene refers to a pair of organic compounds that have similar chemical properties and molecular structures. Both α-phellandrene and β-phellandrene are cyclic monoterpenes and double-bond isomers. Both are miscible in ether but insoluble in water.
α-Phellandrene gets its name from Eucalyptus phellandra (now called Eucalyptus radiata),1 from which it can be isolated. It is also an element of the essential oil of Eucalyptus dives.
α-Phellandrene has been found to reduce pain sensitivity and increase energy levels.2 It also contains potential anti-cancer properties.3 It is easily absorbed, making it a common additive to a host of cosmetic products and fragrances because of it’s pleasing aromas.
β-Phellandrene is widely distributed in essential oils (angelica, eucalyptus, lavandula, mentha, pinus species). β-Phellandrene has been found and isolated from the oil of water fennel and balsam oil. β-phellandrene has been described to have a minty and citrusy characteristic odor. β-Phellandrene is often used as a flavor ingredient.
The phellandrenes have been a staple in holistic Eastern medicine for a long time, used for its antifungal and antibacterial properties.
Before the phellandrenes were discovered, these compounds were assumed to be pinene and limonene due to their similar characteristics. The phellandrenes are most prominent in eucalyptus,4 but also found in herbs and spices including in allspice, lavender, black pepper, cinnamon, pine, mint, water fennel, dill, and cannabis.
Phellandrene is found in the cannabis strains Trainwreck, Jack Herer,5 Ace of Spades, and SAGE.6
