Abstract

Genotoxic substances are those which are capable to induce a destructive effect on a cell’s genetic material. It can be either carcinogen, mutagen, teratogen or cytotoxic depending upon the dose, duration and mode of usage. Mutations may manifest in many forms as duplication, deletion or insertion.  However, all mutagens are genotoxic, not all genotoxins induce mutations.

Irrational long-term usage of any plant-based drug are capable to induce adverse reactions.
