Results found essential oil in all organs of the plant such as root, stem, small branch and leaf, but the most was in leaf. The essential oil is a yellow liquid, heavier considerably than water. In the above- ground organs, there is almost 98,45%-99,03% of methyl salicylat. In the root, this content is lower, an addition with other components such as delta- tetradecalaction caryophylen oxid, nootkalon
