Introduction: Oral cancer is considered to be a global pandemic. The study was conducted to assess the anti-cancer activities of Chlorhexidine (CHX) and Cranberry against oral cancer cell lines. Material and Methods: Anticancer activity of CHX and Cranberry extract (CE) was assessed against AW13516 (poorly to moderately differentiated squamous cell carcinoma of tongue) and KB (Nasopharyngeal carcinoma) using Sulforhodamine B (SRB) assay at the Advanced Centre for Treatment Research and Education in Cancer (ACTREC) Mumbai, India. Three dose related parameters GI50, TGI and LC50 were calculated for each drug. Results: CE (80micro g/ml) showed no anti-cancer property against AW13516 cell line; however it showed 70.6% growth inhibition against KB cell line. CHX demonstrated 80.15% & 95.7% of growth inhibition against AW13516 & KB cell line respectively. Both the drugs were less potential than positive control drug Adriamycin, as reflected by their GI50, TGI and LC50 values. Conclusion: CHX exhibited better anti-cancer properties than CE for both the oral cancer cell lines.
