Abstract

Frankincense has been used as a traditional medicine for treating rheumatoid arthritis, dermatitis, and muscle pain. In this study, the anti-tuberculosis effects of Frankincense were evaluated in immune responses of macrophages. Frankincense methanol extract was not cytotoxic to the host. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide reduction assay using human macrophage (THP-1) cells did not show cytotoxic effects or morphological changes with treatments of 31.3, 62.5, and 125 ㎍/mL Frankincense methanol extract (FRM). Inhibitory effects of Frankincense methanol extract on the growth of Mycobacterium tuberculosis in human macrophages were investigated. The immune response was measured by monitoring the levels of TNF-α and IL-1β in THP-1 cells with or without M. tuberculosis infection under Frankincense methanol extract treatment. Inflammatory cytokine levels and M. tuberculosis numbers were reduced in THP-1 cells treated with Frankincense methanol extract. Therefore, Frankincense methanol extract could be used as a potential anti-tuberculosis agent.
