Abstract:

Biological and pharmacological assays of the extracts of Gentiana oliveri and its pure alkaloid gentianine indicated to be highly efficacious. Toxicity in vertebrates was evaluated by chronic toxicity assay in rats. LD50 was found to be greater than 1000.

At lower doses it was found to be non-toxic.
