Distribution and habitat

It is common in China (specifically Anhui, Fujian, Gansu, Guizhou, Hebei, Heilongjiang, Henan, Hubei, Hunan, Inner Mongolia, Jiangsu, Jiangxi, Jilin, Qinghai, Shaanxi, Shandong, Shanxi, Sichuan, and Zhejiang) and portions of the Russian Far East (up north to the Amur River valley and on Sakhalin Island, and east to Transbaikalia in Siberia), [2] but relatively rare on the Korean Peninsula. Asiatic toads are also found on the Miyako Islands of southern Japan, although they have been extirpated from some islands in recent years, possibly including Okinawa. The Miyako subspecies, Bufo gargarizans miyakonis, is also known as the Miyako toad. [1]

The Asiatic toad avoids dense forests, but is found in most other habitats, including grasslands, open forests, meadows, and cultivated areas. It prefers humid areas, and is seldom found at altitudes of more than 800 meters. [1]

Relationship with humans

The Asiatic toad plays an important role in traditional Oriental medicine. An extract of the toxins secreted by the toad, known as toad venom or chan-su, has long been touted for its medicinal properties. In addition, dried toad skins have been prescribed as remedies for dropsy and other ailments. More recently, Western medical science has also taken an interest in the toad. In 1998, an antimicrobial peptide was extracted from the toad, and patented. [3]

Common toad Species of amphibian

The common toad, European toad, or in Anglophone parts of Europe, simply the toad, is an amphibian found throughout most of Europe, in the western part of North Asia, and in a small portion of Northwest Africa. It is one of a group of closely related animals that are descended from a common ancestral line of toads and which form a species complex. The toad is an inconspicuous animal as it usually lies hidden during the day. It becomes active at dusk and spends the night hunting for the invertebrates on which it feeds. It moves with a slow, ungainly walk or short jumps, and has greyish-brown skin covered with wart-like lumps.

Bufotoxins are a family of toxic steroid lactones or substituted Tryptamines of which some may or may not be toxic. They occur in the parotoid glands, skin and venom of many toads and other amphibians, and in some plants and mushrooms. The exact composition varies greatly with the specific source of the toxin. It can contain 5-MeO-DMT, bufagins, bufalin, bufotalin, bufotenin, bufothionine, epinephrine, norepinephrine, and serotonin. Some authors have also used the term bufotoxin to describe the conjugate of a bufagin with suberylarginine.
