Aerial partsMethanol extractThe animals treated with a single dose of 5000 mg/kg of M. spicata extract by oral gavageNo mortality during the observation period[113]
No toxicologically significant hematological and biochemical changes
Any morphological changes in the heart, liver, kidney, and lung tissues of the rats
LD50 is considered to be >5000 mg/kg
LeavesEthanolic extractThe animals treated with a single dose of 10000, 12000, 14000, 16000, and 18000 mg/kg BW of M. spicata extract by oral gavageNOEL dose for M. spicata was 10000 mg/kg[114]
100% mortality at 18000 mg/kg BW
LD50 = 13606 mg/kg BW
