Objective: Tuberculosis (TB) is the threatful infectious disease that dwell about one third of worlds. Among Middle East, Iraq occupy the fifth order country endemic with TB.

Methodology: Six mixtures of Argan oil: 1.5% H2O2 were prepared at different ratio: 1=0.75:9.25, 2=1:9, 3=1.5:8.5, 4=2:8, 5=2.5:7.5, 6=3:7 and mixed with Lowenstein-Jensen (L-J) medium. Seventeen Mycobacterium tuberculosis isolates got from the consultants clinic of respiratory and thoracic diseases in Hilla city-Iraq. All isolates cultured on LJ medium containing the mixture of Argan oil: 1.5% H2O2 in different ratio and control tube (LJ without mixture) also used. The growth monitored per a day and recorded at different interval and the inhibition (no growth) were recorded.

Results: The effect of Argan oil: 1.5% H2O2 mixture on the Mycobacterium tuberculosis were investigated over three incubation intervals (14th -20th, 21st -28th and after 29th day). The results revealed the high Argan concentration mixture 2.5:7.5 and 3:7 give excellent inhibitory effect on Mycobacterium tuberculosis during full periods of incubation with inhibition percentage (64.71%-82.35%).

Conclusion: The current study aims to investigate the effects of argan oil on Mycobacterium tuberculosis and conclude the anti-mycobacterial activity of argan oil as a safe medication for prophylaxis and treatment of TB.
