A study published in The American Journal of Chinese Medicine assessed the protective effects of baicalin, a major flavonoid of Scutellariae radix, on liver injury in a mouse model. The study was carried out by researchers at Chang Gung University in Taiwan.
Acetaminophen causes acute liver failure, and baicalin has been reported to have liver-protective properties in traditional medicine.
For the study, the researchers induced liver injury in mice by administering 300 milligrams per kilogram body weight (mg/kg) of acetaminophen.
Thirty minutes after acetaminophen administration, they treated the mice with baicalin at concentrations of 15, 30, or 60 mg/kg.
Acetaminophen administration resulted in significant increases in alanine transferase (ALT) enzyme levels and hepatic myeloperoxidase (MPO) activity.
However, these increases were significantly reduced after baicalin treatment in a dose-dependent manner.
Baicalin at a dose of 30 mg/kg exhibited the strongest beneficial effects.
Baicalin treatment at 30 mg/kg reduced elevated hepatic cytokine levels and macrophage recruitment around the area of hepatotoxicity in immunohistochemical staining.
In addition, it decreased extracellular signal-regulated kinase (ERK) expression.
These results suggested that treatment with baicalin can effectively reduce liver injury by down-regulating the ERK signaling pathway and inflammation.
In conclusion, baicalin can be used as a liver-protective agent.
