Higher plants used extensively in traditional medicines are increasingly being screened for their role in modulating the activity of environmental genotoxicants. The property of preventing carcinogenesis has been reported in many plant extracts. The observation of a close association between carcinogenesis and mutagenesis has extended the survey to include plant extracts and plant products able to modify the process of mutagenesis, which involves alteration in the genetic material. Natural plant products may, apart from inducing mutations, modify the action of other known mutagens on the living organisms by 1) activating the existing mutagens within the cell, 2) inhibiting the production of mutagens in the cell, 3) synergising the activity of existing mutagens, or 4) activating the promutagens within the cell into mutagens. This review deals with data obtained in the course of research on the modulatory effects of plant extracts on mutagenesis and clastogenesis, two genotoxic phenomena associated with carcinogenesis.read more

Broad spectrum antimutagenic activity of antioxidant active fraction of punica granatum L. peel extracts.
TL;DR: High content of ellagitannins is revealed which might be responsible for promising antioxidant and antimutagenic activities of P. granatum peel extract which is to be explored to understand the exact mechanism of action as well as their therapeutic efficacy.

Inhibitory effect of Emblica officinalis on the in vivo clastogenicity of benzo[a]pyrene and cyclophosphamide in mice.
TL;DR: The data indicate that the possible mechanism of inhibition by plant extract is mediated by its modulatory effect on hepatic activation and disposition processes.

Cytogenotoxicity of Cymbopogon citratus (DC) Stapf (lemon grass) aqueous extracts in vegetal test systems
TL;DR: The results showed that the highest concentration of aqueous extracts reduced the mitotic index, the seed germination and the root development of lettuce, and the extracts have also induced chromosome aberrations and cellular death in the roots cells of L. sativa.

Potential Genotoxic and Cytotoxic Effects of Plant Extracts
TL;DR: The medicinal use of plants is probably as old as human kind itself and many of the plants species used for this purpose have been found to contain therapeutic substances which can be extracted and used in preparation of drugs.

Antimutagenic effects of several subfractions of extract from wheat sprout toward benzo[a]pyrene-induced mutagenicity in strain TA98 of Salmonella typhimurium.
TL;DR: It is concluded that the extract from wheat sprouts contains at least 2 heat-resistant compounds located within the cell cytosol and showing antimutagenic activity: one group is of low molecular weight and another of high MW.

Modification of Cytotoxic Effects of Inorganic Arsenic by a Crude Extract of Allium sativum L. in Mice
TL;DR: The frequency of chromosomal aberrations was significantly lower in animals maintained on crude plant extract as a dietary supplement during exposure to sodium arsenite as compared to those treated with arsenite alone, suggesting that a crude extract of Allium sativum protects against the clastogenicity of Sodium arsenite.
