Legends, Myths and Stories
Originating from northwest China and Tibet, this herb has been in
use for over 2000 years. Gradually it spread through India, reaching
Europe during the Renaissance, then into Asia Minor and Turkey. It
was a favorite remedy with early Persian and Arabian physicians.
The healthy and hardy pioneer families dared to venture into the
unknown wilderness on their drive westward in America. They could
take only the necessities of life, such as guns, axes, farm tools,
seeds, and other bare essentials on this hazardous journey. Records
tell us that among the bare essentials the pioneer women included
a piece of rhubarb root to assure themselves and their families of
this medicinal treatment. Rhubarb came a long way in 4600 years of
history from its native home in western China.
