Semen Vaccariae
The classic lactation herb — these small seeds invigorate Blood, unblock the channels, and promote the free flow of breast milk, a cornerstone of postpartum confinement nourishment.
What Is Semen Vaccariae?
Semen Vaccariae (Wang Bu Liu Xing, 王不留行) is the dried ripe seed of Vaccaria hispanica, a small annual plant of the carnation family. Its memorable name — literally "the royal who does not stay" — captures the herb’s essential character: a strong, moving, unblocking action that keeps things flowing and refuses to let stagnation settle.
Bitter and neutral in nature, Semen Vaccariae enters the Liver and Stomach channels. It invigorates the Blood, unblocks the channels, and is one of the most celebrated herbs in Traditional Chinese Medicine for promoting lactation — making it a natural choice for postpartum and confinement soups. It also promotes menstruation and helps reduce swelling. Its downward, free-flowing nature makes it especially suited to relieving milk stagnation and supporting the smooth, abundant flow of breast milk in nursing mothers.
History & Origin
Semen Vaccariae has been used for some two thousand years, and is best known through the classical saying that pairs it with another herb to powerfully promote milk flow.
