  Just because an ingredient is labeled "natural" doesnít mean itís safe. Many plants and plant extracts can cause harmful health effects ranging from mild irritation to even death.  

Species Information

Most biomedical research involves mice and other rodents. Their small size and low cost makes them ideal for laboratory experiments. In addition, scientists can breed different strains with natural genetic deficiencies to achieve specific models of human diseases. However, a variety of other animals are occasionally used as well.

Below is a list of animals used in research, and some of the types of research they have been used in.

Armadillos

Are researchers using more and more animals every year?
The number of animals used in research has actually declined in the past 20 years. As technology advances, researchers are able to rely on computer models and other methods instead of animal testing. Some estimates show a reduction in animal use as high as 50 percent. Since 1967, the number of cats used in research has dropped 66 percent.
