Another publication may explain it:
“Geranium oil has been used in perfumes and as a food additive since the 1800′s. It is on the GRAS (Generally Regarded As Safe) list of the United States Food and Drug Administration. Geranium oil is extracted from plants of the family Geraniaceae, frequently by steam distillation of fresh plants. A variety of species of geranium plants exist throughout the world.
