*4.9. Radioprotective and Chemoprotective Activity*

A methanolic extract of *M. koenigii* was demonstrated to render protection in chromosomal damage against radiation and cyclophasphamide in vivo. Radiation leads to a rise in all types of aberrations, like the fragmentation of chromatids and breakages in chromosomes, rings, and dicentrics. Treatment with a methanolic extract of *M. koenigii* before radiation significantly reduced the aberrations. *M. koenigii* can significantly exert bone marrow protection against radiation and cyclophasphamide [121].
