Summary
Rattan Cane or Calamus rotang is a dioecious rattan palm that grows up to 10 m tall and 200 m wide. It is native to India, Sri Lanka, and Myanmar but can now be found throughout Southeast Asia. The leaves are pinnate, alternate and with spines on the upper face. The flowers are clustered and enclosed by spiny spathes. Young shoots are cooked and eaten as vegetable. The fruits are edible as well and yield an astringent red resin known as ?Dragon?s blood?. Dragon?s blood is used as a dye, in painting, and in medicine against respiratory and gastrointestinal problems. It is also used as treatment for wound, diarrhoea, fever, dysentery, mouth ulcers, and skin conditions. The wood of C. rotang is also used medicinally to expel intestinal worms. The leaves are used for biliousness and blood diseases, and the root for fevers and as antidote to snake venom. C. rotang yields the best rattan cane among other species. It is split into strips and plaited, used in baskets, chairs, and carriages, made into ropes, etc. Found In: Asia, Australia, Bangladesh, East Timor, India, Northeastern India, SE Asia, Sri Lanka, Timor-Leste. Other Names: Bet, Chachi bet, Heart, Pemu, Perambu, Raigong, Tingdon, Vetasa, Vetra, Rattan, Rotang, Rattan Cane

It is split into strips and plaited or woven into baskets, chairs, sofas, and carriages. It is twisted into ropes, or stretched entire across rivers, as the main supports of indigenous suspension bridges[ 387 ]. The core of the cane is made into furniture, basketry etc[ 317 ]. The skin peel is used for weaving of chair seats and bags[ 317 ].
Cultivation details
Most species in this genus are more or less vigorous climbing plants in rainforests. In general, they are likely to grow best with their roots in the shade but with their stems able to grow up to the light. They are also likely to grow best in a humus-rich soil[ K ]. A dioecious species, both male and female forms need to be grown if fruit and seed are required.
