Herein a br-ief review, with 49 references, of the history and phytoch
emistry of toxic honeys, in which bees have sequestered plant secondar
y compounds naturally occurring in plant nectars (floral and extraflor
al). It is hypothesized that such toxic honeys could have served as po
inters ro psychoactive and other medicinal plants for human beings exp
loring novel ecosystems, causing such plants to stand out even against
a background of extreme biodiversity. After reviewing various ethnome
dicinal uses of toxic honeys, the author suggests that pre-Columbian Y
ucatecan Mayans intentionally; produced a pychoactive honey from the s
hamanic inebriant Turbina corymbosa as a visionary; substrate for manu
facture of their ritual metheglin, balche.
