Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Vietnamese sophora (Sophora flavescens, often referred to as "Khổ sâm" in Vietnam) has a long-standing history of use in traditional medicine systems, including Traditional Vietnamese Medicine (TVM) and Traditional Chinese Medicine (TCM). In these traditions, the root is used to "clear heat," "dispel wind," and "remove toxins," which are conceptual frameworks that often align with treating febrile illnesses such as colds with fever. The underlying belief is that herbs like Vietnamese sophora help reduce internal heat and support the body's natural defenses during infections.

From a scientific perspective, there are some laboratory studies indicating that Sophora flavescens contains alkaloids and flavonoids with anti-inflammatory, antiviral, and immune-modulating effects. However, direct clinical evidence supporting its efficacy specifically for treating colds with fever in humans is lacking. Most of the support for using Vietnamese sophora in this context comes from traditional use rather than from well-conducted clinical trials. Therefore, the evidence is rated as moderate (2/5), reflecting a solid traditional foundation with limited scientific validation for this specific indication.
