Ecbalium elaterium has a very violent effect on the body and has little use in modern herbalism. Little is known about the acute and chronic toxicities of ecbalium elaterium in human. This study aims to determine the acute toxicity (LD₅₀) of fruit extract and another aerial part extract of the ecballium elaterium in experimental animals. Thus, male albino mice were divided into different groups each group consists of six mice receiving 40, 46, 52, 61, and 69 mg/kg of fruit extract of ecballium elaterium, respectively. Other groups were given 1000, 1412, 1995, 2818, and 3981 mg/kg of the areal part of ecballium elaterium extract, respectively. The LD₅₀ in both treatments was determined by using the Spearman-Karber method. The LD₅₀ of the fruit and aerial parts of ecballium were 55 mg/kg and 2112.5 mg/kg, respectively. The present findings showed significant weight loss after one month of treatment with 1400 mg/kg and 40 mg/Kg of fruit and aerial part extracts, respectively. The results indicated that the fruit extract is highly toxic as compared to the extract of the aerial parts.
