Guīlínggāo, also known as Tortoise Jelly (though not technically correct) or Turtle Jelly, is a jelly-like Chinese medicine, also sold as a dessert. It was traditionally made from the powdered plastron (bottom shell) from the turtle Cuora trifasciata (commonly known as "three-lined box turtle", or "golden coin turtle", 金錢龜) and a variety of herbal products, in particular, China roots Smilax glabra (土伏苓, Tu fu ling).Although the golden coin turtle (Cuora trifasciata) is commercially farmed in modern China, it is extremely expensive; therefore, even when turtle-derived ingredients are used in commercially available guīlínggāo, they come from other, more commonly available, turtle species.
