Thermal-extraction context

Reported biological activity

Human evidence

Clinical evidence for isolated β-pinene remains limited.

Animal or laboratory evidence

Cellular studies report cytotoxic and antioxidant properties; this claim remains uncited in the archive ¹.

Traditional or anecdotal claims

Associated with herbal steam preparations.

Cannabis laboratory results

Measured at 0.14–0.53 mg/g dry weight in two US hemp cultivars by validated GC-MS of hydrodistilled oil; typically minor relative to β-myrcene and limonene in the same samples ². See Lab Results for batch analyses.
