Among the common people, traditions were passed down orally, but the royal court probably kept ancient reference texts on the subject of traditional Thai medicine. Sadly, most of these were lost when Burmese invaders destroyed the old capital of Ayutthaya in 1767. The remaining fragments, however, were commissioned to be re-drawn as stone etchings by King Rama III in 1832, and today, over sixty such epigraphs displaying treatment points, herbal remedies and energy lines are on public display at the famous Wat Po temple complex in Bangkok.
