It can be extracted from a variety of plants, including Strychnos toxifera and Chondrodendron tomentosum. Curares are active only by an injection. They are harmless if taken orally because curare compounds are too large and too highly charged to pass through the lining of the digestive tract to be absorbed into the blood. (L1256)"}]
