This plant is cultivated in South Asia and Southeast Asia for its medicinal uses, and is cultivated elsewhere as an ornamental. In some areas Cheilocostus speciosus is introduced and has become an invasive species.

The habitat where this species is found is roadside ditches and low-lying areas in tropical forests. Flowering starts after onset of the rainy season.

The plant has many historical uses in Ayurveda, where the rhizome has been used to treat fever, rash, asthma, bronchitis, and intestinal worms. It is mentioned in the Kama Sutra as an ingredient in a cosmetic to be used on the eyelashes to increase sexual attractiveness. It is used to treat kidney problems and other urinary problems in Mizo Traditional Medicine. It was used as a traditional medicine by Malays when evil spirits have possessed a body,[5] as well as for the treatment of high fever, smallpox and as a purgative.[6]
