Mare's milk is the milk produced by female horses, known as mares. It has been consumed by various cultures for centuries, particularly in Central Asia, where it is often fermented to create a traditional drink called koumiss. Mare's milk is rich in nutrients, including vitamins, minerals, and proteins, making it a valuable food source. Unlike cow's milk, mare's milk has a lower fat content and a higher lactose level, which can make it easier to digest for some people. It is also known for its slightly sweet taste and is sometimes used in skincare products due to its moisturizing properties.
