The plant today

Bombax ceiba, like other trees of the genus Bombax, is commonly known as cotton tree. More specifically, it is sometimes known as Malabar silk-cotton tree; red silk-cotton; red cotton tree; or ambiguously as silk-cotton or kapok, both of which may also refer to Ceiba pentandra. This Asian tropical tree has a straight tall trunk and its leaves are deciduous in winter. Red flowers with 5 petals appear in the spring before the new foliage. It produces a capsule which, when ripe, contains white fibres like cotton. Its trunk bears spikes to deter attacks by animals.

Recorded in the Philippines

GBIF holds 27 records of this plant from the Philippines. The ones with map coordinates fall in 4 provinces: Laguna (4), Rizal (4), Bulacan (1), La Union (1).

Counts from GBIF occurrence records, October 2026. They include planted trees and garden plants, and a province with no records may only lack collectors.

Uses

In India the roots are used to obtain an astringent and alterative effect and form part of a well-known aphrodisiac mixture called Musla-Samul. If the trunk is incised, an astringent gum exudes and this they use in diarrhœa, dysentery and menorrhagia. Dose of the gum 2½–3 grams.
