The commercial tree is most heavily cultivated in the rainforests of Asia, notably in
Java (hence one of its common names), the Philippines, Malaysia, and
Hainan Island in China, as well as in South America. The flowers are an important source of
nectar and
pollen for
honey bees and
bats. Bats are the primary pollinators of the night-blooming flowers.
Kapok fibre Native tribes along the Amazon River harvest the fibre to wrap around their
blowgun darts. The fibres create a seal that allows the pressure to force the dart through the tube. The fibre is light, very
buoyant, resilient, resistant to water, but very flammable. The process of harvesting and separating the fibre is labour-intensive and menial. It is difficult to
spin, but is used as an alternative to
down as filling in mattresses, pillows, upholstery,
zafus, and stuffed toys such as teddy bears, and for
insulation. It was previously popularly used in
life jackets and similar devices, until synthetic materials largely replaced the fibre.
Traditional medicinal uses Ceiba pentandra bark
decoction has been used as a
diuretic, as an
aphrodisiac, and to treat headache, as well as
type II diabetes. It is used as an additive in some versions of the psychedelic drink
Ayahuasca.
Seed oil A
vegetable oil can be pressed from the seeds. The oil has a yellow colour and a pleasant, mild odour and taste, resembling
cottonseed oil. It becomes rancid quickly when exposed to air. Kapok oil is produced in India, Indonesia and Malaysia. It has an
iodine value of 85–100; this makes it a nondrying oil, which means that it does not dry out significantly when exposed to air. The oil has some potential as a
biofuel and in paint preparation. ==Religion and folklore==
