Clerodendrum serratum and Premna herbacea are two sources of the plant-drug Sirutekku used in Siddha medicine. When the ethanol extracts of roots of these two plants were tested on two gram-positive and six gram-negative bacterial strains, the former exhibited highly significant activity against Streptococcus pyogenes-A and Proteus mirabilis, while the latter showed mild inhibition against Staphylococcus aureus and Pseudomonas aeruginosa. These results support our claim that C. serratum can be equated to Sirutekku.
