In addition to contains 313 ppm tocopherol that transverse 95% free radical in 12 ppm concentration. Percentage of its inhibition constantly to highest consentration. This study aims to describe the liver histopathology Swiss Webster given by Myrmecodia pendans stew, after the mice were induced with CCl4. This research is an experimental research laboratory with a completely randomized design (CRD). A total of 20 male mice (Swiss Webster) were divided into 4 experimental groups (A, B, C, D). Each group consisted of 5 mice. Mice were given pellets and induction by carbon tetrachloride for 5 days. On the 6th day, given Myrmecodia pendans stew with dose of 0.24 cc / day and 0,48cc / day . Termination is done 2 times (each for 2 mice in one time termination). From the results, sarang semut stew (Mymercodia pendans) is able to repair damaged liver cells, although the mechanism of this still unknown. Generally, Mymercodia pendans believed to stimulate the proliferation of the liver cells and simultaneously neutralize free radicals produced by CCl4 that cause of liver cells demaged. Conclusion: Administration of sarang semut with dose of 0.24 cc / day for 10 and 14 days give effect to protect the liver and improve the process of liver cell damage.
