That depends on your definition of "naturally."
I am aware of many individuals who have successfully corrected Scoliosis with the use of effective regular yoga practices.
Consult yoga studios and schools to learn more about this method of treating such Scoliosis.
Additionally,
if you believe chiropractic, acupuncture, or physical therapy are natural approaches,
you can use these therapies as well, as they may be beneficial.
The milder the Scoliosis and the sooner natural therapy is initiated, the more likely beneficial effects will occur.
