**Introduction: **Tapak Liman (*Elephantopus scaber* Linn) is a medicinal plant in Indonesia which traditionally used as a treatment for fever, gout, dysentery, hepatitis, and infections.** Aim:** This study aims to determine the immunostimulants activity of tapak liman extract with carbon clearance method and to determine the percentage and total leukocytes and relative lymph weights.** Materials and Methods:** Twenty white male mice divide assigned to 1 control group and 3 experimental groups. It treated by oral administration of tapak liman extract; 10, 30, and 100 mg/kgBW. After six days of administration, mice intravenously injected with 0.1 ml/10gBW colloidal carbon. Blood obtained from the mice tail at; 3rd, 6th, 9th, 12th and 15th minutes. The determined absorbance then calculated to obtain the phagocytotic index, the percentage and the total of leukocyte cells and lymph weights. **Results: **Phagocytosis index increased significantly at 1, 12, 1.24 and 1.47. The percentages of neutrophil segment are 57%, 60% and 60%, for lymphocytes are 3, 80%, 32.80% and 34.20%, monocyte cells are 4.60%, 3.00% and 2.60%, neutrophil are 3.40%, 3.20%,2.20%, and for the eosinophil cells are 3.20%, 1.8% and 1.20%. Total leukocyte cells are 10,760, 11,630 and 15,880 cells/microliter. The relative lymph weight of each dose in the sequence is 0.36, 0.49 and 0.66. **Conclusion: **Ethanol extract of tapak liman leaves (*Elephantopus scaber* Linn) can increase the immunity of mice.
