Hepatoprotective Activity of an Herbal Composition, MAP, a Standardized Blend Comprising Myristica fragrans, Astragalus membranaceus, and Poria cocos.

Historically, botanicals have been reported to possess good antioxidative activities as demonstrated by their free radical scavenging property rendering their usage in liver protection. In this study, we describe the potential use of MAP, a standardized blend comprising three extracts from Myristica fragrans, Astragalus membranaceus, and Poria cocos, in ameliorating chemically induced acute liver toxicities. Acetaminophen (APAP) and carbon tetrachloride (CCl4)-induced acute liver toxicity models in mice were utilized. Hepatic functional tests from serum collected at T24, histopathology analysis, and merit of blending three standardized extracts were evaluated. MAP administered at doses of 150-400 mg/kg showed statistically significant and dose-correlated inhibitions of serum alanine aminotransferase (ALT) ranging from 30.8% (P ≤ .05) to 88.1% (P = .0001) in the APAP and 66.9% (P = .002) to 83.7% (P = .0002) in the CCl4 models, respectively. Moreover, MAP resulted in up to 75.7%, 60.9%, and 33.3% reductions in serum aspartate aminotransferase (AST), bile acid, and total bilirubin, respectively. Mice treated with oral doses of composition of MAP at 300 mg/kg showed statistically significant reduction in hepatocyte necrosis when compared with vehicle control. Unexpected synergistic protection of liver damage was also observed. Therefore, the composition, MAP, could be potentially utilized as an effective hepatic detoxifying agent for the protection of liver damage.
