Perilla oil

Perilla is an annual herbaceous plant native to Asia. There are two main types of perilla: red perilla and green leaf perilla or oba. Both types are commonly called shiso. Perilla leaf oil is pepared by steam distillation and has a stimulating, fresh, aromatic, greenish odor (perilla-like, picked ume-like). The major component in 29 of 36 perilla leaf samples was perillaldehyde, while in other leaf samples, the major components were reported as dillapiol, elsholtziaketone or perillaketone.
