Positive effects: antidepressant; gastroprotective; anti-inflammatory and antioxidant; antiproliferative (anti-tumour); antifungal; antimicrobial

Limonene is one of the most recognizable terpenes, with a bright, vivid, almost rapturous citrusy tang that’ll have you reaching for the curd before you can say “lemon meringue pie.” On top of its predominance in citrus rinds and many strains of cannabis, it’s also abundant in the essential oils of rosemary, juniper, and bergamot. The aroma of limonene—sweet, fruity, and ever so slightly bitter—elicits an uplifting experience that has the ability to improve a person’s mood, energy levels, and sense of well being. In cannabis, limonene contributes to a more elevating and energizing experience, one that’s notably anxiety-relieving and antidepressant. Limonene also seems to decrease the mental fatigue or “burnout” experienced by some after cannabis consumption.

Terpene talk #1 introduced myrcene, the most abundant terpene in the cannabis plant, an anxiety-easing and stomach-pleasing powerhouse. In a similar fashion to myrcene, limonene is gastroprotective, helping to protect cells in the gastrointestinal tract against damage and inflammation. Limonene seems to exhibit equally or more potent anti-ulcerative effects in comparison with myrcene; we can now attribute this to limonene’s unique ability to neutralize stomach acid and inhibit its production.  These qualities suggest it may be an especially effective treatment for heartburn, gastritis, peptic ulcers, and gastroesophageal reflux.

Limonene has demonstrated anti-inflammatory and antioxidant properties, helping to ease systemic inflammation and protect cells from damage. This may be useful in the treatment of a range of inflammatory and autoimmune diseases, and especially in the prevention or treatment of cancer. In one study, limonene was shown to collect in cancerous tissues, slowing tumor progression and improving outcomes in breast cancer patients.

 Many terpenes, present in the cannabis plant, are antibacterial, antiviral, and antimicrobial, and they seem to play a role in protecting plants from all sorts of bugs and bacteria. Limonene delivers these effects in spades and can function as a topical disinfectant or antiseptic. Limonene even neutralized a rare and treatment-resistant infection known as MRSA, suggesting it may be a novel antibiotic!

As you might have guessed from its uplifting and energizing profile, limonene is most commonly found in sativa and sativa-dominant hybrid strains. Some notable limonene-rich strains include “Super Lemon Haze,” “San Fernando Valley OG Kush,” “Sour Diesel,” and “Sour Tangie.”
