Red-Rooted Sage (Salvia miltiorrhiza), also known as Danshen, has been used in traditional Chinese medicine for centuries. Its primary historical use has been to support cardiovascular health, but it is also traditionally used for liver (hepatic) support. In traditional Chinese medicine, Danshen is believed to "invigorate the blood," "remove blood stasis," and "cool the blood," which are thought to benefit liver function, particularly in cases of liver congestion or chronic liver diseases.

The scientific evidence for Red-Rooted Sage's effects on the hepatic system is limited but growing. Some laboratory and animal studies indicate that extracts from Salvia miltiorrhiza may have hepatoprotective, anti-inflammatory, and antioxidant properties. These effects suggest potential benefits in protecting liver cells from damage and reducing liver fibrosis. However, robust clinical trials in humans are still scarce, and the quality of available evidence is not strong enough to draw definitive conclusions.

In summary, the use of Red-Rooted Sage to support the hepatic system is primarily justified by traditional use, with some preliminary scientific support but a lack of sufficient high-quality clinical evidence.
