In ancient times fermented tea leaves were used as a peace symbol or peace offering between warring kingdoms. Nowadays, the laphet tray is a main expression of hospitality offering to houseguests. The culture of laphet, the production of laphet from tea leaves, and the health benefits of its active compounds were analyzed from scientific articles on fermented tea leaf, green tea, and collected data from tea leaf-producing areas. Laphet is of Myanmar origin and not derived from other cultures. It is an essential popular dish for traditional ceremonies in Myanmar.
