Herbal Turtle Jelly (guī líng gāo) is a traditional Cantonese dessert with a medicinal focus. Made from turtle shell powder, herbs, and sometimes sweeteners, it is consumed for its cooling properties and believed health benefits, such as detoxification and skin nourishment. Nutritionally, it provides minerals and protein, though it is primarily valued for its medicinal qualities. The jelly is served chilled and has a slightly bitter taste, often balanced with honey or syrup. It has a long history in southern China, reflecting Cantonese integration of food and herbal medicine. Herbal Turtle Jelly exemplifies Cantonese philosophy of functional cuisine—combining taste, nutrition, and wellness. Its preparation is careful, ensuring the correct concentration of herbs and consistency. While less common in modern households, it remains a specialty dessert in traditional tea shops and medicinal food establishments.
