Abstract This Study aims to do an initial sterilization process in the excavation site after extraction of some organic artifacts from the burial environment immediately, using natural materials, volatile aromatic oils, without using any chemical pesticides that may react adversely with the materials and can be toxic to the public and harmful to the environment. This is summarized in performing an industrial laboratory aging (heat and humidity) for different samples (acacia wood and linen), then infecting them with common fungal infection, then completely inhibiting fungal growth using some aromatic oils (cinnamon and thyme) at a concentration of 1% using the evaporation method as the best technique in application which has proven effective in inhibiting fungi without causing any color change compared to spraying method.
