Strychnos ignatii is a tree in the Loganiaceae family, native to the Philippines, particularly in Catbalogan and parts of China. The plant was first described by the Moravian (Czech) Jesuit 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 fruit of S. ignatii is the size and shape of a pear, and has almond-like seeds known as Saint Ignatius' beans.[1]
