Oak trees are found though out the temperate regions of the northern hemisphere, making them a very common site on many landscapes in the US. It is a highly valued wood for fireplaces but it also has many more uses for the survivalist.
Identifying The Plant
The National Audubon Society states in their Field Guide to California that, Oaks are "highly variable in shape, oak leaves may be deeply lobed or unlobed, toothed or untoothed; different shapes sometimes occur on a single tree. Of the species found in California, all but four are evergreen. Evergreen oaks are somewhat drought-tolerant and usually have rather small leaves. Oak flowers are minute, greenish, simple in structure, and unisexual. Flowers of both sexes occur on the same tree. Males are clustered into slender pendulous spikes called catkins, which produce copious pollen. Females occur singly or in short spikes at leaf axils; after fertilization, each tiny pistil develops withing one or two years into an acorn with a scaly cap."
The oaks of the mid-west are not evergreen. They usually have bigger leaves that change brilliant colors in the fall and fall off completely for the winter.
The acorns are highly edible but must be leached of the tannons before consumption occurs. This involves leaching the ground up interior of the acorn for at least three days in water that is being flushed and replenished or is running constantly.
Acorn Tea is very yummy. See my past article on that: Acorn Tea: Warms the Body and Soul
One of my biggest worries when stuff hits the fan is the lack of anti-biotics or first aid cream to treat abrasions and combat infection. Never fear though, oak bark makes an extremely effective antiseptic and anti-fungal rinse. Simply boil a handful of the bark in water and then put the whole mixture into a mason jar and let it sit for two weeks. After the two weeks strain out the remaining bark. Store the mixture in a mason jar. It will not go bad. Do not put this mixture in your eyes unless it is highly watered down. You can gargle it for toothaches and mouth sores.

Attention Use At Your Own Risk I am not medically trained in anyway. I am simply a student. I read and experiment with ancient herbal techniques. I am simply passing on the knowledge I have gained from studding many texts on the subject and I am in no way responsible for anything you do with this information.
