Strychnos ignatia is a tree in the Loganiaceae family, native to the Philippines and parts of China. The plant was first described by the Czech Jesuite working in the Philippines, brother Georg Kamel who named its fruit as the Bean Of St. Ignatius, after the founder of his religious order.
The plants was originally named by Kamel for Saint Ignatius of Loyola, the founder of Kamel's Jesuit missionary order. It is known in the Philippines under the names of: aguwason, dankkagi (Visayan language) or igasud (in Cebuano language).
The beans of the plant contain the alkaloids strychnine and brucine. Strychnine is highly toxic, with an LD50 of 1-2 milligrams per kilogram, and was formerly used in rat poisons. Brucine is also toxic, but less so.
The plant is the source of a homeopathic remedy known as ignatia, ignatia amara, or as iamara, which is used to treat grief, depression and other conditions.
