Grapefruit oil
Cold-pressed essential oil from grapefruit peel containing limonene and furanocoumarin compounds. Furanocoumarin (bergapten) content a concern. IMPORTANT: grapefruit interactions with CYP3A4 apply primarily to grapefruit juice (furanocoumarins in juice membrane).
How it works (mechanism of action)
Acts on cellular signalling pathways relevant to the documented clinical indications. Contains bioactive compounds with enzyme-modulating, receptor-binding, or antioxidant properties studied in peer-reviewed literature.
CYP3A4 INTERACTION: Bergapten and other furanocoumarins in grapefruit inhibit CYP3A4 — significant drug interaction potential with statins, calcium channel blockers, immunosuppressants, and many other medications. Cold-pressed peel oil contains furanocoumarins (unlike steam-distilled oil). Photosensitisation with topical use. Furanocoumarin content must be assessed.
