  2. Introduction • The united States is home to thousands of species of plants. • There are a big variety of harmful and completely harmless plants • Some of these plants can cure diseases. • If you eat certain plants in a case of survival it can also cause awful disease and some can even kill a man.

  3. Toxicity Levels There are several different toxic levels of plant life including: • Highly Toxicity: If ingested these plants may cause serious illness or death. • Low Toxicity: If swallowed these plants may cause minor illnesses such as vomiting or intestinal problems. • Calcium acids: The juice or sap of these plants contains oxalate crystals. These crystals can irritate the skin, mouth, tongue, and throat, resulting in throat swelling, breathing problems, burning pain, and stomach discomfort. • Skin Irritation: The sap of these plants may cause a skin rash or irritation.  • Can be fatal to cats or other pets: Will not usually affect humans at all.

  4. Harmful Plants Many food plants possess toxic parts that are toxic unless processed, or are toxic at certain stages of their life. Notable examples include: • Apple Seeds contains toxins but the amount found in a single fruit won't kill a person; but it is possible to ingest enough seeds to provide a fatal dose. • Chocolate. Contains toxins that at certain levels can be harmful to dogs and cats. • Tomato Foliage and vines contain alkaloid poisons which cause digestive upset and nervous excitement.

  7. Ways to Identify Harmful Plants To avoid potentially poisonous plants, stay away from any wild or unknown plants that have: • Milky or discolored sap. • Beans, bulbs, or seeds inside pods. • Bitter or soapy taste. • Spines, fine hairs, or thorns. • "Almond" scent in woody parts and leaves. • Grain heads with pink, purplish, or black spurs. • Three-leaved growth pattern.

  8. Edible but NASTY!!!! • Many wild plants are edible but barely tolerable due to poor taste. • Methods used to improve the taste of plant food include soaking, boiling, cooking, or leaching. • Leaves, stems, and buds can be boiled. • Boil, bake, or roast tubers and roots. • Acorns can be leached in water (like coffee). • Nuts such as chestnuts, are okay raw.

  9. Temperate Zone Edible Plants • Blackberries (Rubus species) • Blueberries (Vaccinium species) • Cattail (Typha species) • Chestnut (Castanea species) • Dandelion (Taraxacumofficinale) • Daylily (Hemerocallisfulva) • Strawberries (Fragaria species)
