It is a typical component of modern medical care throughout East Asia and in some parts of Southeast Asia (such as Thailand). Insects are very commonly incorporated as part of the herbal medicine component of traditional Chinese medicine, and their medical properties and applications are broadly accepted and agreed upon. Some brief examples follow:
Two medically important spider genera have a worldwide distribution—Latrodectus and Loxosceles. Others have a limited distribution. Medical reports have been criticized for poor evidence. [2] In the last century, both white tailed and wolf spiders were considered medically significant, only to be recanted. [3]

Many invertebrates are responsible for transmitting diseases.
The welts often develop into white pustules that should not be scratched, as to avoid secondary infections. A few individuals are sensitive to the venom, and can, on rare occasions, die of anaphylaxis. [3] In a survey of 29,300 physicians in the United States of America (in 1989), reports of 83 fatalities were obtained. [4]
