The plants are poisonous but used medicinally in small amounts.
Although P. K. Lôc made the necessary transfer to Callerya, a note by the same author in Fl. Cambodge, Laos & Vietnam (30: 43. 2001) suggests that the author saw only one incomplete specimen from that Flora region and that more material in flower and fruit would be required to confirm its identity.
