Bu Gu Zhi (Psoralea corylifolia), also known as Po Gu Zhi (破故纸) or Hei Gu Zi (黑故子), is the dried ripe fruit of a traditional herb revered in Traditional Chinese Medicine (TCM) as Bǔ Gǔ Zhī (补骨脂).

Its nature is pungent, bitter, and warm, making it a deeply restorative herb for anchoring the Kidney and Ming Men fire.

Quality & Sensory

Each batch is naturally sun-dried to preserve the fruit's dark brown to blackish color, firm texture, and characteristic warm, slightly resinous aroma. The whole fruit is small, kidney-shaped, and dense. When decocted, it releases a deep, earthy, mildly pungent flavor with a subtle bitterness, lending warmth and body to soups and tonics. The salt-processed form carries a faint saline note from traditional processing, while the powder offers a fine, even texture that disperses easily in warm liquids.
