Genetic toxicity in vitro
Description of key information
Negative in the Ames when tested as an isolated substance snd as an unrefined plant extract
In in-vitro SCE study, there was a slightly significant increase in SCE frequency in all doses tested compared with the solvent control. It should be noted that a similar increase was seen for the crude plant extract assays reported as part of the same research.
