White Perilla Seed Bai Su Zi 500g Dried Perilla frutescens Seeds for Traditional Herbal Decoctions

White Perilla Seed, known in TCM as Bai Su Zi (白苏子), is the dried mature seed of Perilla frutescens, a close relative of Zi Su Zi (紫苏子). These small, pale seeds are a classic Chinese herbal ingredient traditionally associated with moistening the lungs and resolving phlegm, and with supporting smooth qi flow in the chest. In TCM theory they are considered pungent in flavor and warm in nature. Commonly decocted, crushed into powders, or added to herbal formulas, they should be used under the guidance of a qualified practitioner.

Traditional Uses

In traditional Chinese herbal practice, Bai Su Zi is traditionally associated with directing lung qi downward, transforming phlegm, and moistening dryness, and it frequently appears in classical formulas for cough and chest congestion. It is often paired with herbs such as Lai Fu Zi (莱菔子) and Bai Jie Zi (白芥子) in the well-known San Zi Yang Qin Tang combination. Practitioners may also recommend it in autumn and winter decoctions when dryness or phlegm is a concern. Preparation typically involves brief decoction, sometimes with the seeds lightly crushed before use.
