Duhuo & Loranthus Formula (Du Huo Ji Sheng Tang) is a classical formula for painful obstruction in the lower body with deficiency of the liver and kidney. As described in Chapter 43 of Basic Questions: “Painful obstruction in the bones causes heaviness; in the blood vessels causes coagulations and loss of flow; in the sinews causes contractions with an inability to extend the joints, and in the muscles causes numbness.” This manifests in symptoms such as arthritis, and heavy and painful sensations in the lower back and legs with weakness and stiffness. This formula is based on the strategy of both supporting normal qi and removing obstruction. Safflower (hong hua) was added to augment the pain-relieving properties of the formula
