Just a few weeks ago, a Chinese entrepreneur, An Yanshi has revealed that panda poo is the key fertilizer to his new luxury tea, which costs a staggering 70,000 US dollars per kilogram. He claimed that the fertilizer made the tea a health boon because bamboo leaves have the feature of fighting cancer. After the digestion of panda, the priceless panda poo tea has a stronger effect in anti-cancer functions. 　　However, Shi Jun, a botanist in China refuted the An's theory, saying that there is no anti-cancer feature of the giant panda poo tea.Shi believes that the alleged anti-cancer feature just a kind of self-promotion, with no substance. 　　He said that the bamboo leaves does not contain taxol, a kind of cancer-fighting substance found in flora, and nutrition of different types of teas are pretty much similar.In response, the panda poo tea founder just said that he welcomed scientific research over the issue.
