The plant is commonly used as a stimulating tea and medicinal plant in parts of the Caribbean, where it is also used as an insect repellent and cleansing agent.

Known Hazards

Several esters of the diterpene phorbol have been isolated from croton resin. Some of these have shown antileukaemic activity but in general, however, these phorbol esters as found in Croton tiglium and many other Croton species are extremely irritant and also tumour promotors. Their presence in Croton tiglium and Croton flavens means their consumption is sometimes held responsible for certain forms of nasopharyngeal cancer as they are able to activate Epstein-Barr viruses[

Other Uses

Because of their strong volatile emanation, leafy branches are spread beneath heaps of drying sorghum to keep the latter insect-free. Dry leaves may be burned in the house as disinfectant and to eliminate all kinds of insects. When burned for this purpose in combination with leaves of Annona squamosa and the dried plant of Parthenium hysterophorus, the smoke should not be inhaled[
