Description
San Leng (Sparganium stoloniferum), also known as Jing San Leng (京三棱) or Hei San Leng (黑三棱), is the dried rhizome of a traditional herb long revered in Traditional Chinese Medicine (TCM) for its blood-moving and stagnation-breaking character. Its nature is bitter, neutral, and gently warming in action, making it a classic herb for invigorating blood circulation, dispersing accumulations, and easing abdominal fullness. This listing offers both whole dried rhizome pieces and finely milled black San Leng powder, with a vinegar-processed (醋炙) option traditionally used to soften its intensity and guide its action.

When decocted, it yields a lightly bitter, faintly astringent infusion with an earthy undertone, while the vinegar-processed form shows a subtle sour note from the traditional processing.
