It look like a joke....
"A medical student asked an acupuncturist 'where's the proof?'. He replied 'We don't need proof: we have 3000yrs practical experience!'".

Legendary physician Hua Tuo, who was born in 110 A.D. and lived to the unprecedented age (at that time) of 97. He was reputedly murdered by the ruler of the Wei Dynasty after the ruler suspected an assassination attempt when Hua Tuo suggested brain surgery for his severe headaches.

By the stimulation of these specific points at the precise vertebral level, virtually any condition known to man can be positively affected.
