A wildlife expert in China is attempting to launch the world's most expensive tea, using panda poo to fertilise the brew.
An Yashi is a college lecturer at the Sinchuan University believes the tea, which is fertilized with panda droppings, could prevent cancer and fetch a price of up to £50,000 per kilo.
Yanshi believes the rich aromas from the special blend will make it a favourite among connoisseurs.
"Pandas have a very poor digestive system and only absorb about 30 percent of everything they eat. That means their excrement is rich in fibres and nutrients," he told Chinese website Scol.com.cn.
"It has a mature, nutty taste and a very distinctive aroma while it's brewing."
He also believes there are serious health benefits to the drink.
"Just like green tea, bamboo contains an element that can prevent cancer, and enhance green tea's anti-cancer effects, if it is used as fertilizer for the tea," the professor said
Yanshi is aiming to secure the Guinness World Record for his brew, once the first batch of the blend is ready for sale.
He also already collected around five tonnes of panda excrement for use in manufacturing the tea.
Yanshi is not the first to use animal excrement in an exclusive drink.
The world's most expensive coffee, Kopi Luwak, is made using beans that have been eaten and excreted by the Indonesian civet cat.
