Extract of Nux vomica is used as homeopathic drug to cure various nervous disorders like mental emotion epilepsy, prolepses of the rectum, hydrophobia etc. The given dose of this drug is very small because of its poisonous effect in higher dose. In the present investigation we want to assess toxic effects of Nux vomica on somatic chromosomes of Vicia faba. Four concentrations 5%, 10%, 20% and 30%, were used for the treatment of root tips of test plant. There were number of abnormalities observed like stickiness at orientation of chromosomes, un-organization of chromosomes, fragmentation during separation of chromatids, multiple chromatin bridges formation etc. These types of aberrations were increased with increased concentration and duration of treatment of this drug. https://www.biotech-asia.org/vol14no4/assessment-of-genotoxic-effects-of-nux-vomica-as-homeopathic-drug-on-mitotic-chromosomes-of-vicia-faba/ Chromosomal Aberrations; Genotoxic; Homeopathic Drugs
