This bush is a Yew, and our guide tried to tell us why Yew is important, but Marjorie the Pharmacist knows much better. The chemotherapy drug Taxol comes from the yew tree. It was actually discovered in the Pacific Yew, a very rare tree in the Olympic Rainforest. The bush I’m hiding in is European Yew, and scientists have figured out how to synthesize Taxol from a base of European Yew, which is easily cultivated and doesn’t destroy rare ecosystems.
