Bufotoxin

Bufotoxin is a toxic compound secreted by various species of toads, most notably those belonging to the genus Bufo. The toxin is a complex mixture of substances, including alkaloids, steroids, and peptides, which can have potent effects on the nervous system of predators. Bufotoxin is primarily used by toads as a defensive mechanism against predators.

Chemical Composition

The exact composition of bufotoxin can vary between different species of toads, but it generally contains a mixture of various bioactive compounds. The most well-known of these are the bufadienolides, a group of cardiac glycosides that can have potent effects on the heart. Other components of bufotoxin can include various alkaloids and peptides, which can have a range of effects on the nervous system.

Toxicity

Bufotoxin is highly toxic to many animals, including humans. The toxin can cause a range of symptoms, including nausea, vomiting, hallucinations, and in severe cases, cardiac arrest. The severity of symptoms can depend on the amount of toxin ingested, as well as the specific species of toad. Some species of toads produce a more potent toxin than others.

Medical Use

Despite its toxicity, bufotoxin has been used in traditional medicine in various cultures around the world. In Traditional Chinese Medicine, for example, dried toad venom, known as Chan Su, has been used to treat a variety of conditions, including heart failure and skin infections. However, the use of bufotoxin in medicine is controversial due to its high toxicity and potential for misuse.

Ecological Role

In the wild, bufotoxin serves as a defensive mechanism for toads against predators. The toxin is secreted from glands in the toad's skin when it is threatened, deterring predators from eating the toad. This has allowed toads to survive in a variety of environments and has contributed to their success as a group.
