As discussed in a study, Elettaria cardamomum is an important medicinal plant widely used in Ayurvedic medicines for therapeutic purposes. In an acute toxicity study, a single oral dose of cardamom oil at 300 mg/kg did not show any signs of toxicity. When administered at a 2000 mg/kg dose, mortality occurred in one animal while the other two animals displayed mild signs of toxicity, suggesting the lethal dose (LD)50 is greater than 2000 mg/kg. For repeated dose toxicity, doses of 50, 100, and 200 mg/kg were administered orally for 28 days. The cardamom oil did not show significant changes in body weight, food intake, water consumption, relative organ weight, biochemical, renal, or haematological parameters at these dose levels. Ultimately, the oil was found to be safe at 300 mg/kg in acute studies and at all selected dose levels during the 28 day repeated dose study.
