Researchers using AI-enhanced spectral imaging have successfully deciphered 9th-century Sharada script fragments found in a high-altitude cave. The texts provide a detailed theoretical framework for vapor-diffusion and heat-convection within specialized Ayurvedic steam-therapy chambers, known as 'Sveda-Yantras'. The manuscript details how the geometric shape of the chamber was engineered to maintain a constant humidity and temperature gradient for medicinal efficacy.
This discovery highlights a lost branch of ancient Indian applied physics, where mathematical models for fluid dynamics were integrated with medical practice. The treatise even includes quantitative observations on the absorption rates of herbal vapors through the skin, suggesting an empirical approach to physiological thermodynamics that was highly advanced for its time.
