Organic Ku Shen (Sophora Root): Benefits, Uses & Traditional Chinese Medicine Guide
Some herbs nourish. Some herbs warm.
Ku Shen clears.
For over 2,000 years, Ku Shen (Sophora Root) has been one of the most respected bitter roots in Traditional Chinese Medicine for clearing heat, drying dampness, and supporting skin, digestion, and overall internal balance.
Known botanically as Sophora flavescens, Ku Shen is especially valued when excess heat, dampness, irritation, or skin imbalance becomes the problem.
Its intensely bitter taste tells you exactly what kind of herb it is.
This is not a gentle tonic herb.
This is a powerful clearing herb traditionally used to support skin wellness, healthy digestion, and internal balance.
