  • Plants of the genus Arum are poisonous because they contain calcium oxalate. Currently, there is no standard, accepted medicinal use of the plant, although Arum may have been used to treat prostate disease and skin conditions. Extracts from Arum are being studied for their ability to fight against sperm and therefore, may be used to prevent pregnancy (contraceptive).
