Phytolacca is a genus of perennial plants native to North America, South America, East Asia and New Zealand. Some members of the genus are known as pokeweeds or similar names such as pokebush, pokeberry, pokeroot or poke sallet. Other names for species of Phytolacca include inkberry and ombú. The generic name is derived from the Greek word φυτόν (phyton), meaning "plant," and the Latin word lacca, a red dye. Phytolaccatoxin and phytolaccigenin are present in many species which are poisonous to mammals if not cooked properly. However, the berries are eaten by birds, which are not affected by the toxin because the small seeds with very hard outer shells remain intact in the digestive system and are eliminated whole.
