Rating (out of 5): 2

Walnut (Juglans regia) has been used in traditional medicine systems, such as Traditional Chinese Medicine (TCM) and various folk remedies, for supporting general health, including liver health. In TCM, walnuts are sometimes considered to "tonify the kidneys and lungs," and are occasionally included in formulations intended to support the liver. However, the specific use of walnut for "liver detoxification" is not a prominent or universally cited traditional application.

From a scientific standpoint, there is limited direct evidence supporting walnut's role in liver detoxification. Some animal studies suggest that walnuts possess antioxidant properties and may have a protective effect on the liver when exposed to toxins, likely due to their content of polyphenols, omega-3 fatty acids, and other bioactive compounds. For example, preliminary research has indicated that walnuts may help reduce liver fat accumulation and oxidative stress in animal models of non-alcoholic fatty liver disease (NAFLD). However, these findings are not conclusive, and robust clinical trials in humans are lacking.

In summary, the use of walnut for liver detoxification is primarily supported by traditional practices rather than strong scientific evidence. While walnuts are nutritious and may indirectly support liver health through antioxidant effects, there is no high-quality evidence to confirm their efficacy specifically for liver detoxification in humans.
