Influenza, commonly known as "flu," is caused by a viral infection and is characterized by symptoms including chills and sweats, a dry cough, nausea, fever and vomiting. Influenza is highly contagious, and according to the University of Maryland Medical Center, causes 35,000 deaths every year in the United States. If you are suffering from flu, staying in bed and drinking plenty of fluids will usually help you to recover. Over-the-counter analgesics such as acetaminophen or ibuprofen may also help to relieve aches and lower a high temperature. Some herbs may have anti-viral properties, but evidence that they can treat flu is limited.
Echinacea
Echinacea may help to treat influenza, but evidence that it is effective is mixed, the University of Maryland Medical Center, UMMC, states. The results of a study published in the May 2010 of the medical journal, "Vaccine," show that echinacea was able to alter the course of influenza infection, but the study was carried out in an animal model, not people infected with the influenza virus. Short-term echinacea use is likely safe, according to MedlinePlus, but side effects may include nausea, dry mouth, dizziness and insomnia. This herb may interact with a number of drugs and should not be used by people with auto-immune disorders. Ask your doctor if it is safe for you.
Garlic
Garlic may help to reduce the risk of getting flu, but scientific evidence to show that it is effective is lacking. However, MedlinePlus notes that is may alleviate flu symptoms, including fever, coughs, headache and sinus congestion. Garlic is likely safe, but may cause bad breath, body odor and heartburn, especially when eaten raw. Do not take garlic if you have a stomach or gastrointestinal problem, or if you have a bleeding disorder, as it may make your condition worse. This herb interacts with a number of drugs, including the birth control pill and anti-HIV drugs. Ask your doctor if it is safe for you to use garlic.
Elderberry
An article published in the January 2010 issue of "Phytotherapy Research" notes that elderberry extract may be useful for the treatment of viral influenza infections. UMMC adds that it may shorten flu duration. Consuming elderberry juice extract for up to five days is likely safe, says RxList, but using it for long periods may not be safe. Do not use this herb if you are pregnant or breastfeeding, or if you have an autoimmune disorder.
