Recently, a number of researches have been carried out and it has been proven to possess various pharmacological activities like antidiabetic, hypolipidemic, diuretic, antioxidant, anti-microbial and anti-cancer. Methods: Macro-microscopy and TLC investigation for the leaves of C. igneus were done using standard methodology. Results: The chief microscopic characters of leaves include epidermis with anomocytic stomata, mesophyll cells with calcium oxalate crystals and fibres associated with parenchyma cells. TLC of ethanolic extract showed 7 and 12 spots at short UV nm and long UV respectively. Conclusion: This study will serve as a standard reference for identification of Costus igneus Nak. leaf.
