Dong leaves, also known as Dong Quai leaves, come from the Angelica sinensis plant, which is commonly used in traditional Chinese medicine. These leaves are often dried and used in herbal remedies, believed to support women's health, particularly in regulating menstrual cycles and alleviating symptoms of menopause. In addition to their medicinal uses, dong leaves can also be found in various culinary dishes, especially in Asian cuisine. They have a slightly sweet and earthy flavor, making them a popular ingredient in soups and stir-fries, adding both taste and nutritional benefits to meals.
