In Chinese herbal practices, Hóng Táng — 紅糖, "red sugar" — is the whole, unrefined cane sugar that keeps its molasses, minerals, and deep amber colour. Li Shizhen recorded cane sugar in the Ben Cao Gang Mu (1578), and in folk practice brown sugar is used to warm the middle burner (溫中), nourish and invigorate blood (補血活血), and harmonize the stomach (和胃). It is the base of "brown sugar ginger tea" and the Five Red tonic that Chinese mothers prepare for daughters during their cycle, after childbirth, and in cold weather. In this role it is not merely a sweetener but a warming carrier for the other herbs.
In Western nutrition science, unrefined brown cane sugar is studied under names such as non-centrifugal sugar, jaggery, and panela. Unlike white sugar, it retains polyphenols, flavonoids, Maillard-reaction antioxidants, and minerals including iron, calcium, potassium, and magnesium. Modern research has examined its antioxidant capacity and mineral content, though it remains a sugar and is used in LunarSip blends in modest, traditional amounts.
