Bitter almond oil is different than that of sweet almond because it contains amygdalin.
Bitter almond oil is rich in Vitamin E, monounsaturated fatty acids, proteins, potassium and zinc, besides a number of other minerals and vitamins, which explains why it is so good for the human heart, skin and hair. Bitter almond oil does have some medicinal properties too. The bitter almond tree (prunus dulcis, var. amara) contains pure benzaldehyde.
