What is rasayana?
Rasayana is the branch of Ayurveda devoted to rejuvenation and long life, using herbs, diet and daily practices meant to strengthen the body and slow decline.
If most of medicine is about repairing a car after a breakdown, rasayana was about regular servicing to keep the car running well for as long as possible.
Why it matters for aging
Classical texts describe rasayana as combining herbal preparations with lifestyle: a calm mind, good sleep, moderate eating and regular routine. Famous rasayana remedies include ashwagandha, amla (Indian gooseberry), triphala and shilajit.
Interestingly, rasayana's focus on prevention and resilience rather than treating disease is the same shift modern geroscience, the science of aging, is now making.
A common myth
Rasayana herbs are proven anti-aging medicines.
Rasayana's goal matches modern longevity science, but most rasayana remedies haven't been tested in good human trials. A few, like ashwagandha, have evidence for specific effects such as stress, not for slowing aging itself.
