Pinene

Pinene is the most abundant terpene in nature and the compound responsible for pine's distinctive scent. It exists in two main forms — alpha-pinene and beta-pinene — with alpha-pinene being more common and bioactive [1]. Beyond coniferous trees, you'll find significant concentrations in rosemary, basil, dill, and parsley, as well as citrus peels and eucalyptus [2].

As a monoterpene with the molecular formula C₁₀H₁₆, pinene belongs to a class of volatile organic compounds that can cross the blood-brain barrier and influence neurological function. What makes pinene particularly interesting is its demonstrated ability to improve cognitive function while acting as a natural bronchodilator — properties that have made it a focus of both traditional medicine and modern research [3].

In cannabis, pinene typically appears in concentrations ranging from 0.1% to 1.5% of total terpene content, though some pine-scented strains can reach up to 3%. The terpene's volatility means it's easily lost during processing, making fresh, properly cured material essential for maximum pinene content.
