Cajuput Oil is a colorless, pale yellow, greenish or turquoise-colored, mobile liquid of powerful. fresh, eucalyptus-like, camphoraceous odor and a burning-aromatic taste. Characteristic are the almost fruity-sweet body notes and the soft tones in the dryout. The green color is not an indication that the oil is genuine. This was earlier assumed. and many price lists emphasized that the green color was synonymous with genuineness.
