Caraway Seed Oil (aromatherapy)

Rectified caraway oil is colorless or very pale yellow. The odor is stronger, less fatty. The flavor is warmer, less sweet and more biting than that of the crude (natural) oil.  Crude caraway oil is the direct distillate. It is a pale yellow to brownish, mobile liquid, possessing a strong and peculiar odor typical of the fruit, but with a fatty-harsh undertone. The taste is similar, but quite burning, warm, biting.
