Tree of Heaven Poisoning – What Is It?

The term “tree of heaven” refers to a variety of trees with long, narrow leaves. These are used for making paper and other products such as rope, twine, cloth, etc. They have been grown in China since ancient times. Some varieties grow up to 20 feet tall and can weigh over 100 pounds! Trees like these are called “tallow maples.”

The leaves contain a toxic substance called tannin. Tannins are found naturally in many plants, but they are especially concentrated in the leaves of trees. When ingested, the toxin causes vomiting, diarrhea and stomach cramps. If not treated immediately, it can cause death within hours or days if left untreated.

Trees of this type are sometimes called “stink maples,” because their leaves smell bad. The poisonous nature of the leaves makes them ideal for use in stinking rooms where there is no air circulation and no ventilation. These trees have been used in Chinese medicine for centuries, so they are very popular around the world today.
