A study done at Cytogenetics and Molecular Biology Laboratory, Department of Zoology, University of Kalyani, India has shown that the remedy Arnica montana prepared in a 30c potency reduced the damage and oxydative stress of a bacteria that was exposed to ultraviolet (UV) irradiation.

The researchers concluded: “Arnica montana-30C helped repair the DNA damage through up-regulation of repair genes and also ameliorated the oxidative stress through the reduction of ROS generation and suitable modulation of anti-oxidative stress enzymes.”
