Toad, commonly known as toad, is not only a pastoral guard who preys on pests, but also provides good medicine for human beings, and it is also a nutritious food animal. Its meat is more delicate and delicious than frogs. It is listed in Shanghai and Zhejiang every year to eat more than frogs, because it is a kind of medicinal and edible animals with high economic value. Toads (toads) are distributed all over the country, with Chinese toad and black orbital toad as big, high value and excellent varieties.

The whole body of toad is treasure. Toad venom is the white milk secreted by the retroauricular gland and skin gland of the head of toad. It is a valuable traditional medicine in China. According to the Compendium of Materia Medica, toads have the effects of reducing fever, removing dampness and killing insects, and are an important medicine for the treatment of scourge, carbuncle and sores. According to medical analysis, toads contain toad toxin, arginine and other substances, as well as cardiotonic steroids, which are widely used in clinic, such as cardiotonic, diuretic, exciting breathing, detumescence and resuscitation, detoxification, anaesthesia and pain relief.

There are dozens of proprietary Chinese medicines made from toad venom in China, and they are also favored in foreign pharmaceutical markets. In recent years, the demand for toad venom at home and abroad is increasing day by day, and the price has soared from 800yuan per kilogram in 2005 to 1800 yuan per kilogram in 2006. At present, the purchase volume of Bufonis in China can only reach half of the market demand, and the price of Bufonis is still on the rise.

The epidermis of toad is called toad skin and toad slough. According to the Great Dictionary of Chinese Herbal Medicine, it is a kind of medicine that can treat malignant tumors and other difficult diseases. It is mainly used for sores and ecchymosis in children. Now it is commonly used to treat tumors. Toads in the wild take off their clothes dozens of times a year, but they are often eaten by the toads themselves, and people rarely get a chance to collect them, unless the toads take off when they are sick and stay in the grass or in the rubble. Although toads can be found all over the country, at present, few people have mastered the technology of collecting toad clothing, coupled with the unique medical effect of toad clothing, so it is very popular in the major medicinal materials market.

According to relevant data, toads naturally take off their clothes every seven days or so after being excited by two natural elements, and the yield is very high, and there is no need to stimulate toads with a drop of medicine. The toad clothes taken off are natural products with few broken clothes and high clothing rate.

At present, due to the extensive use of pesticides and chemical fertilizers, the environment is polluted, the ecology is destroyed, and the number of toads decreases sharply. Artificial breeding of toads has become a trend. Toads do not have high requirements for habitat environment, breeding technology is very simple, almost no feed cost, hanging electric lights in the farm to tempt insects to feed on their own. Toads have a high reproduction rate, and a pair of toads can lay about 3000 eggs a year. If we can realize large-scale breeding, and then master the technology of toad venom extraction, toad clothing collection and processing, the economic benefits are not small.
