Objective:
To reduce the chances of toxicity, reduction in radiation dose or reducing the frequency of the therapy is done
which usually leads to a therapeutically poor outcome. The most feasible method is to protect the normal cells by
administration of radioprotective agents either before or after the exposure. These agents have been tested on animals and
human cellmodels for evaluating theirsafety window and toxicityprofile at the cellular level. The study aims to compile the
effective natural radioprotective agents available which can be further exploited by using certain QSAR studies to increase
their potency.
Method:
Structured literature search from EMBASE, PubMed, Bentham Science, Scopus, and ScienceDirect was done and
appropriate peer-reviewed review articles, as well as certain research articles, were included and compiled in this review
paper.
Conclusion:
As various studies have indicated the harmful effects of ionizing radiations on normal cells, to reduce these
effects radioprotective agents are used before or after exposure to radiations. Compounds derived from natural sources are
proved to have few side effects and they possess radioprotective property due to the presence of alkaloids, resins, volatile
oils, tannins in their molecular structure. Various plants having such radioprotective constitutes have been identified for
their radioprotective action and compiled in the present study.
