Why people make this tea
Every spring when fresh hawthorn berries appear in Hong Kong markets, Nourilo is reminded of this simple little tea. The fresh berries are a vivid red, slightly tart, and irresistibly appealing — and their food-therapy value is substantial. Modern pharmacological research has confirmed what Chinese folk medicine has long held: hawthorn has vasodilatory effects, supports healthy blood pressure, lowers cholesterol, and strengthens cardiac muscle function. Paired with roselle — the deep crimson hibiscus calyx widely enjoyed in beverages across the world — the result is a beautiful, jewel-coloured tea that is genuinely pleasant to drink. Both ingredients’ vitamin C content is protected by natural acids (malic acid, hawthorn acid) and remains stable even after boiling, which is a useful piece of food science. In summer, served chilled, this tea is one of the most refreshing thirst-quenchers you can make.
