Description
It is a tree which can reach a height of 12 m (40 ft). The large
leaf stalks wither and fall off the tree and collect near the base
of the trunk, appearing to look like a pile of broken limb bones.
The tree is a night-bloomer and flowers are adapted to natural
pollination by bats. They form enormous seed pods that hang down
from bare branches. Those long fruits curve downward and resemble
the wings of a large bird or dangling sickles or swords in the
night.
The seeds are round with papery wings.
Distribution
Oroxylum indicum is native to the Indian subcontinent, in the
Himalayan foothills with a part extending to Bhutan and southern
China, in Indo-China and the Malesia ecozone.
It is visible in the forest biome of Manas National Park in Assam,
India. It is also reported from Sri Lanka (Ceylon).
Ecology
Oroxylum indicum lives in relationship with the actinomycete
Pseudonocardia oroxyli present in the soil surrounding the roots.
Uses
The tree is often grown as an ornamental for its strange
appearance. Materials used include the wood, tannins and dyestuffs.
It is also a plant with edible leaves and stems.
In traditional medicines
The Oroxylum indicum seed is used in the traditional Indian
ayurvedic medicine. The root bark is also used, administered as
astringent, bitter tonic, stomachic and anodyne. It is included in
famous tonic formulations, such as Chyawanprash.
The bark of O. indicum (Chinese : 木蝴蝶树皮, hanyu pinyin : mù húdié
shùpí) or Cortex Oroxyli is a traditional Chinese medicine
ingredient.
The bark of O. indicum (Singhala / Sri Lanka: Totila, Totilla) is
one of main ingredients in Sri Lankan indigenous medicine (in
decoctions) as a remedy for pains in joints or rheumatism.
Pharmacology
The leaf contains chrysin and baicalein. Tetuin, the 6-glucoside
of baicalein, is reported in the seeds. Other flavonoids, known for
their anti-inflammatory and anti-allergy effects, are also present,
though it may need to be used in high doses to get a response.
Oroxindin has also been isolated from Oroxylum indicum whereas
oroxylin A is reported in the root bark |
