Article: At the end of the day, there are very few circumstances where the minuscule amount of calories in berries are worth the risk of getting sick. Even in a survival scenario, it is not worth the risk. Diarrhea, vomiting, and nausea all strip you of vital fluids and sugars, putting you in far more danger than you would have been without the small bit of food.  Just because you see an animal eat a berry does not mean they are safe for humans, this is especially tempting if the animal is a mammal. The following advice is meant to give you guidelines, not hard rules. Never eat a berry you can't identify. In most cases (some botanists guess as high as 90%), these three colors indicate poisonous berries. While a knowledgeable camper might be able to name or find some exceptions, the best rule is to avoid all white, yellow, and green unless you're sure it is safe.  Red berries are roughly 50% safe to eat, so some basic testing may show you what is safe and what isn't. If they are in clusters -- usually bad. Solo berries -- usually okay.  In general, blue, black, and aggregated berries (ie. raspberries, blackberries, etc.) are safe to eat. There are, however, some exceptions (Pokeberry, with its bright pink stalk and dark berries, is very toxic). In general, the following plants are not safe for humans to eat, including the berries. You should check for:  Milky or odd-colored saps. Berries or nuts in pods and bulbs Bitter or soapy taste Spines or small pointy hairs Pink, purple, or black spurs. Three-leaved growth pattern (like poison ivy) A good way to check berries in a pinch is to see if the juices cause any irritation. First, crush the berry on your arm, waiting five minutes or so to see if you get irritated. Then repeat the process on your lips and gums. Finally, chew a berry for 10-15 minutes, but don't swallow it. If none of this causes irritation, move on to the next step. Only test one berry at a time. These tests are useless if you can't tell which of the two berries is causing the problem. If you're in serious doubt, it is best to move on. But if you need the berries for survival, you should eat slowly, seeing how your body reacts. Within 20 minutes you should see symptoms if you're going to get sick.  Even if you're fine after 20 minutes, keep eating slowly. Pace the berries out over a long time to prevent any toxins from gathering and give you time to adjust or note problems. If the berry tastes terrible, then this is a good indicator that it may be poisonous. There are not a lot of hard and fast rules about berries because there is such a large variety. If you are going on a hike or an expedition, carry a book with the names, pictures, and descriptions of berries. This way you’ll know which berry you are looking at. You will likely experience intense digestive disturbance and nervous symptoms. In general, if the following symptoms appear within a few hours of eating the berries, see a doctor immediately:  Nausea Vomiting Dizziness Diarrhea Convulsions Blurred vision Cramps Otherwise fine berries can turn toxic in an instant if covered in chemicals. Smell the berries beforehand, and steer clear of areas near farms, homesteads, or large gardens to be safe.  If you know a berry is safe, but are worried about pesticides, you can still rinse the berries off in clean water and eat them safely.  Chemical poisoning will often bring the same symptoms as poisonous berries.
Question: What is a summary of what this article is about?
When in any doubt, do not eat wild berries! Stay away from white, yellow, and green berries. Stay away from berries on plants with spines, bitter smells, or milky sap. Smash the berries to test the juice on your forearm, lips, and tongue. Eat 1-2 berries and wait 20 minutes if you absolutely must get something to eat. Always look up or carry plant identification information when going to new environments. Know the symptoms of berry poisoning. Avoid any areas sprayed with herbicide, pesticides, or other chemicals.

Problem: Article: Daffodils grow best in full sunlight, however, partial or light shade is also acceptable. Full shade will keep your daffodils from blooming for the first year or two after planting. Daffodils should be planted in the fall, preferably in October. However, you can plant as early as September or as late as November. If you live in colder climates, aim to start your planting 2 to 4 weeks before the ground freezes. Buy your bulbs from a reputable source or nursery, and plant them within a week of purchasing. The larger the bulb, the better. Do not buy bargain bulbs, as they might not have a flower in them.  Never buy or plant a soft daffodil bulb, as that means there is rot or another disease inside the bulb. Bulbs with two tips will produce two stems. Small bulbs may not flower in their first year.
Summary: Pick a site with full sun. Plant the daffodils in the fall. Buy the bulbs when you’re ready to plant.

INPUT ARTICLE: Article: Applying a tourniquet increases the amount of blood in the vein to make them stand out more. The tourniquet should not be so tight that it cuts off the circulation.  The tourniquet should be put on the arm about four inches above the vein. A blood pressure cuff that is inflated to 40–60 mm Hg also works well. Warmth will make the patient's veins dilate and expand, making them easier to see. Contrary to popular culture, you should palpate the arm, rather than slapping it. Slapping the skin is poor technique that may result in a hematoma. Use your index finger to look for a vein, which feels soft and spongy. Don't use your thumb, as it contains its own pulse.  The warm pack or water bottle should be put on the area before it is disinfected. Nothing more should touch the area after it is disinfected. Do not apply the warm pack or water bottle directly to the skin. Wrap it in a thin towel to prevent burns. If it hurts, it is too hot. Many people have needle phobias and nervousness and apprehension is a normal response. Stress not only makes the veins hard to hit, but it could also negatively affect the test results (particularly for biochemistry panels). Reassure your patient and explain that the pain is very brief and minor.  Tell your patient to try visualization and deep breathing. Observe your patient and have them lie down on their back if you think they might faint. This will improve the blood flow to their head. It also reduces their chances of falling and injuring themselves if they do pass out.

SUMMARY: Make sure your tourniquet has been applied properly. Put a warm pack or water bottle over the area. Use proper palpation techniques. Tell the patient to relax.

Work with 1⁄2 tablespoon (7.4 ml) of the dressing at a time. Use your hands to gently toss the dressing through the greens until they are evenly coated. If some of the greens are still dry after adding dressing, put in another 1⁄2 tablespoon (7.4 ml). Don't add too much dressing right away or your salad may get soggy.
