Invitro cytotoxic study of aloe vera whole leaf extract on PBMC and breast cancer cell line

Many anticancer drugs currently used have an origin from natural sources. It is reported that in between 1981 and 2006, 47.1% of the 155 clinically approved anti-cancer drugs, were unmodified natural products or their semi-synthetic derivatives or even synthesized molecules based on natural models

. MTT Assay was performed on PBMC and MCF-7 cell line with aloe vera extract. Experimental data suggest that Aloe vera whole leaf extract significantly increases the cytotoxic effect on human breast cancer cell compare to normal cell (PBMC). Our study evaluated specific cytotoxic effect of Aloe vera extract on human breast cancer cell and further study is required to develop Aloe vera extract base drug for the treatment of breast cancer.
