Grapefruit Oil (aromatherapy)
Grapefruit Oil is a mobile, yellowish to greenish- yellow or pale orange-yellow oil, possessing a fresh-citrusy, rather sweet odor and a similar taste. As mentioned above, the bitterness particularly known from European and Middle-Eastern fruits and peels, is no longer found in today’s American grapefruit oil. The odor resembles that of sweet orange oil to a certain degree, but also has notes in common with bitter orange oil.
