Human Uses

Bauhinia tomentosa is cultivated in gardens and parks as an ornamental tree.

Bauhinia tomentosa is not an important browsing tree for cattle as it contains prussic acid in the pods and the flowers. The goats tend to nibble the leaves but do not consume much. (Agroforestree Database 4.0,Orwa et al.2009)

The branches of Bauhinia tomentosa are used by basket makers.

The wood is used for the construction of huts (as rafters).

The leaves yield a yellow dye.
