Since there is no cure for the common cold, treatment has two goals: to make you feel better and to help you fight off the virus.
From WebMD & Mayoclinic:
Lots of rest is the key treating a cold. You may find you need 12 hours of sleep each night, so don't set that alarm. You'll be most comfortable in a warm, humid environment. It's also important to drink lots of water. This makes mucus flow more freely and helps with congestion.
No specific treatment exists for the virus that is causing your cold, but in treating your symptoms you can find relief. For aches and pains accompanied by a fever of 100.5 degrees or higher, give Tylenol rather than aspirin to avoid the risk of Reye's syndrome, a sometimes fatal condition that occurs in children with viral illnesses, especially if they have taken aspirin. If your throat is sore, gargle as often as you like with salt water (1/2 teaspoon salt in 1 cup water).
Think twice before using heavily advertised over-the-counter cold and flu medications, which likely contain drugs for symptoms you don't have and therefore may result in needless overtreatment. The FDA and manufacturers now say that over-the-counter cough and cold drugs should not be given to children under age 4.
Over-the-counter decongestants containing pseudoephedrine can help dry and clear nasal passages, but only temporarily. Decongestant nasal sprays can help, too -- but watch out! Decongestants used for more than three to five days may cause a "rebound" effect. This means more mucus and worse congestion. Pseudoephedrine may increase blood pressure and heart rate. Do not take it without first checking with a doctor if you have heart disease, high blood pressure, prostate problems, diabetes, or thyroid problems.
Over-the-counter decongestants containing phenylpropanolamine have been pulled voluntarily from the shelves because they increase the risk of stroke. If you have a drug containing this ingredient, also called PPA, throw it away.
Over-the-counter cough suppressants, such as those containing dextromethorphan, can be helpful if your cough is so severe that it interferes with sleeping or talking. Otherwise, allow yourself to cough as you need to (always covering your mouth as you do), because coughing removes mucus and germs from your throat and lungs.
Antihistamines seem to help some people, but their effect during colds remains controversial.
Good nutrition is essential for resisting and recovering from a cold. Eat a balanced diet. Take supplements as needed to ensure you are receiving the recommended dietary allowances for vitamin A, the vitamin B complex (vitamins B1, B2, B5, B6, folic acid) and vitamin C, as well as the minerals zinc and copper. Both vitamin C and zinc are essential for production of infection-fighting neutrophils; without adequate levels, you're an easy mark for all types of infections. Evidence is not clear on whether zinc lozenges or tablets cut colds short -- you can find studies supporting either side of the issue. However, the latest research shows zinc may shorten the duration of a cold and even prevent one if taken regularly.
Despite much research, the jury is still out on whether vitamin C can help prevent or shorten colds. There have been several large studies in adults and in children, but the results have been inconclusive. Taking a lot of vitamin C over a long period of time can be harmful.
Chicken soup has been heralded as a cold therapy since the 12th century. Recent scientific evidence shows mild support for the notion that chicken soup reduces cold symptoms, especially congestion.
Asian healing treatments often use hot soups to treat upper respiratory infections, making use of red pepper, lemongrass, and ginger in particular. Any food spicy enough to make your eyes water will have the same effect on your nose, promoting drainage. If you feel like eating, a hot, spicy soup may help ease your cold symptoms.
To ease cold symptoms, the essential oils of aromatherapy may be rubbed on the body, inhaled with steam, diffused into the air, or poured on a cloth to be used as a compress. Try rubbing diluted eucalyptus oil on the chest as a decongestant, or inhale eucalyptus or peppermint oil to clear stuffiness. Adding lavender, cedar, or lemon to steam may also soothe nasal passages. Inhaling menthol not only provides relief from nasal congestion, but might help inhibit infection as well. Rosemary, thyme, mint, basil, and tea tree oils can also provide relief from symptoms of a cold. Use caution if you have asthma, since aromatherapy can trigger an attack.
Many Americans turn to herbal remedies to ease cold symptoms. Some research supports the use of the Chinese herbal remedies yin chao and gan mao ling. Rather than self-prescribe, it's best to consult an expert practitioner of traditional Chinese medicine (TCM).
Echinacea may help strengthen the immune system by stimulating the activity of white blood cells, but there is little evidence that it can prevent colds in particular. Several studies show adults using echinacea at the first sign of a cold suffered shorter and less severe illness. Because herbs are so poorly regulated and labeled in the U.S., however, it's difficult to know if the product you're using contains the right species and active ingredient. If you decide to try echinacea, take small doses for no more than eight weeks, since prolonged use may suppress your immune system.
Drinking tea or warm lemon water mixed with honey is a time-honored way to soothe a sore throat. But honey may be an effective cough suppressant, too. In one study, children age 2 and older with upper respiratory tract infections were given up to 2 teaspoons (10 milliliters) of honey at bedtime. The honey seemed to reduce nighttime coughing and improve sleep. In fact, in the study, honey appeared to be as effective as the cough suppressant dextromethorphan in typical over-the-counter doses. Since honey is low-cost and widely available, it might be worth a try.
Cold remedies: What doesn't work
Antibiotics. These destroy bacteria, but they're no help against cold viruses. Avoid asking your doctor for antibiotics for a cold or using old antibiotics you have on hand. You won't get well any faster, and inappropriate use of antibiotics contributes to the serious and growing problem of antibiotic-resistant bacteria.
Over-the-counter cold and cough medications in young children. OTC cold and cough medications may cause serious and even life-threatening side effects in children. The FDA warns against their use in children younger than age 2. The Consumer Healthcare Products Association (CHPA) has voluntarily modified consumer product labels on over-the-counter (OTC) cough and cold medicines to state "do not use" in children under 4 years of age, and many companies have stopped manufacturing these products for young children. The FDA is evaluating the safety of these medications in older children.
Take care of yourself
Although usually minor, colds can make you feel miserable. It's tempting to try the latest remedy, but the best thing you can do is take care of yourself. Rest, drink fluids and keep the air around you moist. Remember to wash your hands frequently.
