Universal edibility test • If you are in a survival situation and cannot identify any edible plants you can test plants for safety. Choose a plant that is plentiful.
Check on learning • Name the parts of plant • When you smell the plant what are you checking for? • How long should you fast before beginning the test? • What can you do during the test period? • When you place a small portion on your outer lip, what are you checking for and how long do you leave it in contact? • How long does the whole test take? • Should you do the test for each part of the plant?

Persimmon The genus name for the American Persimmon means "Fruit of the Gods". This is a reference to the delicious golden-orange fruits that often hang on the tree after the leaves drop in autumn. When ripe, these fruits are very sweet. But they must be fully ripe. If you try to eat one too soon, your mouth will likely pucker from the bitter taste of tannic acid. Yet a ripe fruit is a real treat. Native Americans relished them, and they are a popular food for wild turkey, mockingbirds, deer, raccoons, foxes, squirrels, rabbits, and other wildlife. They can be made into pudding, preserves, beer, and brandy, and can also be dried for winter eating.

Oak Trees Oak trees are broadleaved trees. The scientific name for oak trees is Quercus. Oaks are hardwood trees that can live well over 200 years. Oak trees are an important source of food for wildlife. Oak trees produce acorns once a year in the fall. Some oaks begin to produce acorns at age 10 and others do not produce until they are 50 years old. Oak trees may not produce acorns every year. The trees need to store up energy after a heavy production year and thus may produce a very light crop or no crop at all. Heavy acorn production may occur only about 4 out of 10 years. Oak Species: White Oak, Chestnut Oak, Gambel’s oak, Blue Oak, Red Oak

Hemlock Poisoning Water Hemlock Poisoning -- Maine, 1992 On October 5, 1992, a 23-year-old man and his 39-year-old brother were foraging for wild ginseng in the midcoastal Maine woods. The younger man collected several plants growing in a swampy area and took three bites from the root of one plant. His brother took one bite of the same root. Within 30 minutes, the younger man vomited and began to have convulsions; they walked out of the woods, and approximately 30 minutes after the younger man became ill, they were able to telephone for emergency rescue services. Within 15 minutes of the call, emergency medical personnel arrived and found the younger man unresponsive and cyanotic with mild tachycardia, dilated pupils, and profuse salivation. Severe tonic-clonic seizures occurred and were followed by periods of apnea. He was intubated and transported to a local emergency department. Physicians performed gastric lavage and administered activated charcoal. His cardiac rhythm changed to ventricular fibrillation, and four resuscitative attempts were unsuccessful. He died approximately 3 hours after ingesting the root. Although the older brother was asymptomatic when he arrived at the emergency department, he was treated prophylactically with gastric lavage and administered activated charcoal. He began to have seizures and exhibit delirium 2 hours after eating the root; he was stabilized and transferred to a tertiary-care center for observation. No additional adverse effects were reported.
