Quality & Sensory

Each batch is naturally sun-dried to preserve the seeds' dark brown to blackish color, firm texture, and characteristic warm, slightly resinous aroma. When decocted, Bu Gu Zhi yields a deep, earthy infusion with a pungent, mildly bitter taste and a lingering warmth. The prepared (zhi) form softens the raw seed's harshness, giving a smoother, more rounded flavor that blends well in soups and decoctions.
