The eucalyptus tree originated in Australia, but is now grown in many countries worldwide. One use for eucalyptus trees is their oil. Eucalyptus oil has a wide range of uses--from disinfectant to bug repellent to air freshener. Regardless of its intended use, buying commercially prepared eucalyptus oil can be expensive. One alternative is to extract your own if you have access to fresh eucalyptus leaves.
Collect approximately 2 cups of fresh eucalyptus leaves and place them inside a plastic, zippered baggie. Seal the bag.
Lay the baggie on a hard, flat surface and gently tap the leaves with a wooden mallet to bruise them and slightly crush them. Do not try to pulverize them.
Place the bruised and crushed leaves into a canning jar and cover them with pure almond oil or jojoba oil. Cut two vitamin E capsules and squeeze their contents into the jar. The vitamin E will act as a preservative. Seal the jar and shake it to insure that all the leaves are covered with the oil.
Set the jar in a warm, sunny window for 14 days.
Strain the contents of the jar through a cheesecloth into a second clean canning jar. Discard the leaves.
Strain the contents once again through a cheese cloth and into a funnel in order to fill a colored glass bottle. The glass should be amber or blue or any color that reduces the amount of light that reaches the contents. This is your extracted eucalyptus oil.
Store your colored bottle of extracted oil in a cool, dark place. The oil should remain viable for at least six months.
