Capillary Artemisia (Artemisia capillaris), also known as Yin Chen Hao in traditional Chinese medicine (TCM), has a long history of use for supporting liver (hepatic) health. In TCM, it is commonly prescribed to address conditions such as jaundice, hepatitis, and other liver disorders. Traditional texts and pharmacopoeias describe its use for "clearing heat" and "eliminating dampness" from the liver and gallbladder, which aligns with symptoms such as yellowing of the skin and eyes.

Scientific research on Artemisia capillaris provides some preliminary support for its traditional uses. Laboratory and animal studies have suggested that extracts of Capillary Artemisia may exert hepatoprotective effects, such as reducing liver inflammation, protecting liver cells from toxins, and modulating liver enzymes. Some studies have identified active compounds like scoparone and capillarisin that may contribute to these effects. However, robust clinical trials in humans are lacking, and current evidence mainly consists of preclinical data and traditional empirical use.

In summary, the use of Capillary Artemisia for hepatic support is primarily justified by traditional practices, with some early scientific investigations suggesting possible mechanisms but insufficient high-quality clinical evidence to confirm efficacy and safety in humans.
