Description of the substance

Botanical Information:  The plant is a tall, woody, climbing shrub found in the Philippine Islands. The ovate glabrous leaves are in opposite pairs; white tubular flowers give rise to a large puriform berry, about 10 cm. in diameter, which contains up to 24 pebble-like seeds, embedded in a bitter pulp.
     The seeds are heavy, hard, somewhat pyramidal in shape with flattish sides and roughly 20 mm. by 15 mm. in size. The color is greyish or reddish black, the surface smooth with few or no hairs, and if fractured the endosperm is seen to be translucent and to enclose an irregular hollow cavity in which an oblong embryo. The seeds are inodorous but are intensely bitter in taste. One characteristic of the Ignatia subject is bitterness of spirit.
     The seeds, which are used for preparation of the mother tincture, contain proportionately more strychnine than those of Nux vomica. The powdered seeds contain 2.5 to 3 per cent. of strychnine and brucine. (Gibson’s Studies of Remedies).

This is the seed of the  strychnos ignatii,  a climbing bush of the genus  strychnos,  which, like the  strychnos nux vomica,  grows on the Philippine Island, and in India, where it goes by the name of  papreta.  It is known that the name of  St. Ignatius' bean,  was given to this seed, by Father Camelli, in honor of the founder of the order of the Jesuits. The fruit of the  strychnos Ignatii,  which is of the size of a small melon, or a large pear, is ovoid, smooth, and contains from fifteen to twenty seeds, which are of an irregular shape, angular, hard, of the size of olives, o a pale - brown color, and striated on the outside, inodorous, but very bitter.
