Bi Xie (Dioscorea hypoglauca) — Dried Food Herb Rhizome for Tea & Soup

Bi Xie (Dioscorea hypoglauca), also known as Cotton Bi Xie or Mian Bi Xie, is the dried rhizome of a traditional food herb known in Traditional Chinese Medicine (TCM) as Bì Xiè (萆薢). For centuries, Bi Xie has been prized as a damp-clearing, turbidity-resolving herb, traditionally used to support the lower burner, ease joint discomfort, and promote smooth flow of qi and fluids. Its nature is bitter, neutral, and slightly balancing, making it a gentle yet focused herb for drying dampness and separating clear from turbid.
