The English name of swallowroot is sometimes used for the plant and studies have shown that it has insecticidal activity and a potential use in control of stored grain pests. The active ingredient in the root was synthesized and encapsulated with beta-cyclodextrins. The roots were also subjected to supercritical carbon-dioxide based extraction at the Central Food Technological Research Institute, Mysore, India. The plant is often confused with Hemidesmus indicus, Indian sarsaparilla [3] The root contains antioxidants and extraction methods for it have been patented.[4]

The popularity of Decalepis in the international market has recently made its price soar and sends worrying signals about it getting being endangered due to over-exploitation.[5]
