Heartleaf Philodendron

A note attached to an herbarium specimen collected

in Peru in 1969 reads, ('Narcotic, used to

induce sleep" (von Reis and Lipp 1982, 20*). The

principal agent of the allergologically efficacious

plant is thought to be 5-heptadecatrin-8(Z),11 (Z),

14(Z)-benzylresorcinol (Roth et al. 1994, 559*). A

related Montrichardia species is used as an

ayahuasca additive.
