Talmakhana seeds, also known as Asteracantha longifolia or Hygrophila auriculata, have been traditionally used in Ayurvedic medicine for various health purposes. While scientific research on the specific benefits of Talmakhana seeds is limited, they are believed to offer several potential health advantages:
