Anamirta cocculus

Anamirta cocculus is an Southeast Asian and Indian climbing plant. Its fruit, Cocculus indicus, is the source of picrotoxin, a poisonous alkaloid with stimulant properties.

The plant is large-stemmed (up to 10cm in diameter); the bark is "corky gray" with white wood. The "small, yellowish-white, sweet-scented" flowers vary between 6 to 10 centimeters across; the fruit produced is a drupe, "about 1 cm in diameter when dry". [1]

Common names

The English common names are fishberry or Levant nut[5] (both referring to the dried fruit, and to the plant by synecdoche); it is variously known as ligtang, aria (Mindanao), bayati (Tagalog), and variations thereof throughout its natural distribution (the Philippines, East India, Malaysia, and New Guinea).

The name "fishberry" comes from the use of the dried fruit as a method of fishing, in which the fish is "stupified and captured"; this method, however, is considered "unsportsmanlike".[6]
