Protesters of bear bile extraction staged a demonstration dressed in furry costumes in downtown Beijing, March 24, 2012. Chinese bear bile producer Guizhentang has been under fire for in recent weeks since it was revealed it planned to expand its bile production. The company's last IPO attempt in February 2011 floundered amid fierce public opposition. Bear bile has been used as an ingredient in traditional Chinese medicine to cure eye and liver ailments for nearly 3,000 years. [Photo/CFP]
