Four Red Soup (Si Hong Tang)

Why people make this soup

Cancer treatments — especially chemotherapy and radiation — save lives, but they also suppress bone marrow function and reduce red and white blood cell counts. This leaves patients feeling profoundly weak and vulnerable to infection. Traditional food therapy cannot replace medical treatment, but it can offer gentle nutritional support alongside it. This soup uses four red-coloured foods — all associated in Chinese dietary tradition with nourishing blood and supporting haematopoiesis (the body’s blood-making process): red-skinned peanuts, small adzuki beans, goji berries, and red dates. The redness is more than aesthetic; in Chinese dietary theory, red foods are associated with the heart and blood. The peanut skin in particular is specifically associated with supporting platelet production and blood coagulation. This soup is also widely recommended for anaemia, irregular or scanty menstruation, and the nutritional demands of pregnancy and the postpartum period.
