Write a paragraph on the quote : "What natural plants would

It's inevitable that you'll catch a cold or flu from time to time, even if you eat well and wash your hands regularly. While colds don't usually last more than a week, being sick is a universally miserable experience.  But you can use some natural plants to treat cold or flu.
For example :
1. Citrus fruits
Vitamin C, one of the first vitamins that people go to when they feel sickness coming on, can be found in citrus fruits as well as supplemental pills. Research from the U.S. National Library of Medicine's National Center for Biotechnological Information showed that high doses of vitamin C at the onset of a cold can decrease its duration. 
2. Garlic
Garlic has long been touted for its ability to boost your immune system. You can reap the most benefits from eating garlic if you start at the beginning of cold and flu season, but it can shorten the life cycle of your cold regardless. The University of Maryland Medical Center cited a study that found people who took garlic supplements between November and February experienced fewer colds. Additionally, the illnesses didn't last as long for people who were regularly taking garlic. While your breath won't be pleasant, you can mince or chop a clove of garlic to eat each day.
3. Elderberry
This plant has been used for several medical purposes over the years, but it's been proven to decrease the duration of cold and flu symptoms. People often ingest elderberry in the form of Sambucol, an over-the-counter syrup. According to UMM, a study showed that taking Sambucol can shorten the length of the flu by three days. Elderberry also comes in tablets and tea, but it's important that you don't eat uncooked or unripe berries if you're making your own supplements, as they can be poisonous. Be sure to consult your doctor before starting an elderberry regimen, particularly if you have rheumatoid arthritis.
