We choose mice as the experimental animals to study the acute toxicity and chronic toxicity of Datura stramonium. The results show that, the mice can tolerate greater than 4 g / kg and less than 16 g / kg of Datura stramonium. The median lethal dose: LD50=6.82 g / kg, 95% confidence interval for [5.71, 8.59]. Large and long-term administration will damage liver and kidney. Mandala is not suitable for long-term administration in clinical administration. if it is really necessary to give long-term administration, we should strictly control the dosage, and monitor the liver function and renal function
