Dān Shēn (丹参) is the primary herb for activating blood circulation and resolving blood stasis in the Heart and cardiovascular system. The name means "cinnabar root" — 丹 (Dān, cinnabar red) and 参 (Shēn, root) — describing the distinctive red color of the root. A classical saying holds: "one herb, Dān Shēn, does the work of Sì Wù Tāng" — meaning it single-handedly performs the combined blood-nourishing and blood-moving functions of the four-herb formula.
