List of bufotoxins

Some bufo secretions are toxic

The toxic substances found in toads can be divided by chemical structure in two groups:

1. bufadienolides, which are cardiac glycosides (e.g., bufotalin, bufogenin)
2. tryptamine-related substances (e.g., bufotenin)

Ingestion of digoxin-like cardiac glycosides can be fatal. Ingestion of Bufo toad poison and eggs by humans has resulted in several reported cases of poisoning, some of which resulted in death. A court case in Spain, involving a physician who dosed people with smoked Mexican Toad poison, one of his customers died after inhaling three doses, instead of the usual of only one, had images of intoxicated with this smoke suffering obvious hypocalcemic hand muscular spasms.

Species

Toads known to secrete bufotoxins.

Toads frequently "milked"

Despite being a frequent target for milking, these toads still carry cardio toxic bufotoxins which have been linked to deaths.

• 5-HO-DMT (bufotenin)
  • Incilius alvarius (formerly Bufo alvarius)
  • Rhinella arenarum
  • Rhinella diptycha
  • Nannophryne variegata
  • Melanophryniscus moreirae
  • Rana dalmativa
• 5-MeO-DMT
  • Incilius alvarius (formerly Bufo alvarius)

Other toads

The effects of the bufotoxins in these toads are not well understood.

• Anaxyrus americanus
• Bufo bufo
• Bufo melanostictus
• Rhinella marina (formerly Bufo marinus)
