Cubeb (tailed pepper) is a plant cultivated for its fruit and essential oils and mostly found in Java and Sumatra.

It was indeed used in cigarettes, to help treat asthma, chronic pharyngitis and hay fever. Edgar Rice Burroughs once humourously attributed his writing of Tarzan to cubeb cigarettes.

Today, Bombay Sapphire gin and Pertsovka vodka are flavoured with cubeb.
