INPUT ARTICLE: Article: If home remedies do not help to relieve your nausea within a day or so, or if you are vomiting, then call your physician right away to ensure that you don't have a more serious problem. Nausea often along with vomiting is a common problem for many people. The feeling of being "sick to your stomach" can be caused by a number of different things, including: Food sensitivities or food allergies Bacterial or viral infections GastroEsophageal Reflux Disease (GERD) and heartburn Medications, especially chemotherapy and radiation treatments Pregnancy (morning sickness) Migraines and other headaches Motion sickness Pain If you have nausea with or without vomiting and it does not go away within 24 hours, call your physician for an appointment right away. If the nausea improves but you still have no appetite, have a headache or have severe stomach or abdominal pain, call your physician for advice. Nausea, especially when it's accompanied by vomiting can be a sign of a more serious condition such as: Appendicitis Intestinal obstruction or blockage Cancer Poisoning Peptic Ulcer Disease (PUD), especially if the vomit resembles coffee grounds

SUMMARY: Call your doctor if nothing helps or if you have other symptoms. Consider the cause of your nausea. Determine if you may need to seek medical attention.

In one sentence, describe what the following article is about: Woody plants share very similar attributes and growth characteristics with forbs above, and many forbs actually share the same families as woody plants. For instance, caragana mentioned below is in the same family as the clover species and black medic mentioned above, which is Fabaceae, or the Legume (Peas and Beans) Family. The only thing that sets woody plants apart from their herbaceous counterparts is that the stems are not annual (grow up from seed or root growth points every year) like forbs are. The stems also form secondary tissues, primarily xylem, on the interior of the stem, and its these xylem cells, with their very strong and rigid structures, are what make up what we know as "wood." In trees and shrubs subject to seasonal changes, rings develop in the woody tissues in response to growth patterns that occur in the spring and summer. Tropical trees, however, do not form rings because the cambrium (tissue that can grow due to cell division, and makes up xylem [inside layer] and phloem [outside layer], of a plant stem) experiences active growth all year round. Flower and leaf characteristics mentioned above also apply to woody plants, exceptions are those gymnosperms, largely as coniferous plants like spruce and pine trees. Using the basic identifying characteristics described in the step above, find a plant in your garden or flower bed that obviously shouldn't be growing in there and you suspect may be a woody weed of some kind. Woody plants are characterized by structure of the leaves, flowers, seeds or fruit, stems, and growth form. Most who are new to identifying plants feel most comfortable referring to the common name of a plant, and choose to learn the species' scientific, Latin or Greek taxonomic names later. However please note that it's very common for a single plant to have more than one common name, depending on location and the language of those referring to a particular plant, so use of common names exclusively in identifying any plant, weed or not, is discouraged especially in the world's scientific community. This is because many plants have one taxonomic name, and that one taxonomic name is often the name that is easily recognized in all languages in by many people in all regions.
Summary: Understand the characteristics of woody plants. Find or locate a weed that would likely be a woody plant. Examine the plant. Make an identification guess on the species or common name of the plant.

INPUT ARTICLE: Article: Expect viburnum snowball bushes to blossom in May. Heavy pruning should only be done at this time since you can easily destroy next year's flowers by removing old wood. Deadheading, or cutting off the flowers, won't harm viburnum. However, doing it isn't necessary and prevents the plant from growing berries. The oldest branches are the thickest, woodiest ones. They may produce side shoots or have flaky bark that make them easier to recognize. Using a clean, sharp pair of shears, cut as close to the soil as you can to completely remove the shoots. At most, remove no more than of the shoots. Usually, this means removing 1 to 3 shoots at a time. Leave behind the thinner, fresher shoots coming up from the plant's base. These will rejuvenate your viburnum. Although the snowball flowers bloom on old wood in viburnum plants, the oldest shoots produce weak flowers and are safe to remove. Viburnum often grows well when it is left alone, so you may not need to do routine trimming. If your bush gets too large or begins extending out of its spot in your yard, use clippers to reduce its size. Cut the branches as needed. Remember to only perform hard trimming in spring, after the bloom, to avoid damaging the bush's buds the next year. You can trim the branches this way to maintain the snowball bush's rounded shape or sculpt it into a hedge. Viburnum snowball bushes grow relatively quickly, so they can become too tall or crowded. If your bush needs serious work, use shears to trim the shoots and branches back. You can also cut out the larger, older shoots to thin the plant. The best time to do this is around May, after the flowers bloom, although it can be done anytime as needed. After trimming back the plant, you may want to wait and watch it grow back. Then you can see where you need to thin out the branches. By maintaining the bush regularly, you likely won't need to do this. Examine your snowball bush throughout the year to look for broken or rotting branches. With a sharp pair of shears, cut out the damaged parts. If possible, cut above the nodes, which are where new leaves and branches grow off of the old branches. This routine trimming should be done year-round to keep your snowball bush healthy and thriving.

SUMMARY:
Prune the bush after the flowers bloom in spring. Cut the oldest shoots near the ground. Trim the sides of the plant into shape if needed. Reduce the bush's height by if it becomes overgrown. Trim damaged branches down to the new growth throughout the year.
