The use of the Pacific Yew as a modern medicine dates back to the late 1950's and in the early 1960's research was begun on its cancer fighting properties. During this time there was pressure for serious cancer research and the National Cancer Institute (NCI) was formed. One of their agendas was to look for all medicinal plants that could help in the newly declared war against cancer. The NCI contracted the U.S. Department of Agriculture to find samples of many plant species for research.
