One of the easiest terpenes to identify by smell is limonene. As the name indicates, it’s the smell of lemons or other citrus aromas such as tangerine or grapefruit.
Limonene is found in certain cannabis strains as well as in citrus fruit peels in abundance. It is also found in black pepper, caraway, celery, dill, fennel, mint, juniper, rosemary, pine and monk’s pepper. This terpenoid is considered to be the “second most widely distributed one in nature” (Russo, 2011) and the second most common terpene in cannabis after myrcene.
Limonene has been shown to reduce anxiety in mice and rats – but tests on mice and rats in cages don’t always accurately explain what humans who are not in cages experience.
Limonene has been shown to be a powerful anti-depressant in humans. It has also been shown to kill breast cancer cells. It has been patented as a treatment for gastro-oesophageal reflux disease which causes heartburn. Moreover, it is also a powerful anti-fungal agent and has been found to be an effective treatment of skin diseases including acne. It also has a reputation as an immunostimulant – it stimulates the immune system.
Strains famous for their limonene content are:
Super Silver Haze (or anything with a citrus fruit in the name)
