Ouch ... bee therapy causes a real buzz

It may be among China's most controversial therapies, but Liu Yu insists she is able to walk again thanks to the power of bee stings.

The 26-year-old, who has multiple sclerosis, has been receiving bee acupuncture in Beijing for more than two years.

"My treatment is painful," she said. "But I'm sticking to it because my disease is much worse than any bee sting."
