Edible cockroaches making Chinese farmers rich

The demand for edible cockroaches in China is turning a healthy profit for the farmers breeding them.
Cockroach breeder Wang Fuming said business is booming for his cockroaches.
The demand comes from China's pharmaceutical companies, who use the cockroaches in pills to treat illnesses afflicting the stomach, liver and heart.
Wang said he has a special relationship with the cockroaches.
"I love these cockroaches, I feel very close to them," he told CNN.
"Just smell that unique smell they have."
In an industrial district on outskirts of the city of Jinan in eastern China, Wang farms millions of cockroaches.
He keeps the roaches in warehouses with narrow corridors and hives made of cement roof shingles.
There, visitors are greeted by the strong smell of ammonia and the sound of scuttling legs.
Wang breeds American cockroaches and he sells them to pharmaceutical companies in China by the ton.
Insects, including cockroaches, are a valued ingredient of Chinese medicines with its use stretching back more than 5000 years.
