Yup. The Sangre Del Drago is a real tree that grows in South America. It's sap has long been said to have healing properties by the natives, and today there are pharmaceutical companies that harvest it's sap to extract certain enzymes or some such from them for medication.
When I had to create an "Evil, Sentient, Carnivorous Tree" for Year of the Comet, that seems like a great choice to twist.
THe AUthor for War! took it a step further, creating a second Awakened varient of the tree with the Sangre del Draco (Since Sangre Del Drago is "Blood of the Dragon", in my mind I translate Sangre Del Draco to "Blood of the Drake", not certain what he had in mind though) as an awakened version with potentially magical healing properties.
