Every year, the flu causes up to 150,000 hospitalizations and 40,000 deaths in the United States. Although a flu vaccine is available, the flu virus mutates so quickly that it does not always work as well as doctors hope. Further, although prescription flu medications exist, they need to be taken at the first sign of infection to work well. However, you can boost your immune system to prevent and treat the flu. We have scoured scientific research and nutritional supplements to show you the top 6 best natural remedies.

What is the Flu?

Influenza, or the flu, is a contagious respiratory infection. A flu season occurs every year, with a flu virus that changes annually. Although the specific duration of the flu season can vary, it often starts in October and can end as late as May. Flu season often peaks between December and February.

The flu is mainly spread by tiny droplets in the air that pass between people when you cough, talk, or sneeze. These droplets can be so small that you might not even notice them. Once exposed to the flu, you start to develop symptoms within one to four days.

Flu symptoms include:

  • Chills or fever
  • Cough
  • Sore throat
  • Runny or stuffy nose
  • Achy muscles or body
  • Headache
  • Fatigue

You can transmit the flu to others even before you start to show symptoms. You continue to be contagious up to a week after coming down with the illness.

Although anyone can get the flu, certain groups are at higher risk of complications from the infection. These groups include people who:

  • Are age 65 or older
  • Are younger than 5 years old
  • Have asthma
  • Have diabetes
  • Have heart disease
  • Are pregnant

How is the Flu Treated?

If the flu is caught early, several prescription medications exist that can limit the severity of the flu or stop it from developing. However, most of the healing process will take place at home. Tips for fighting the flu at home include:

  • Drink lots of fluids to avoid dehydration
  • Rest and sleep as much as possible
  • Eat chicken soup, which may help to clear congestion
  • Consider over the counter pain relievers like Tylenol (acetaminophen), Advil (naproxen) or Motrin (ibuprofen) if your doctor says they are safe for you to use

If your flu symptoms worsen, it is important to seek medical help. The flu can cause other infections throughout your body that can be deadly. It can also worsen chronic illnesses like heart failure and diabetes, which can also have serious consequences. Seek emergency medical attention if any of the following symptoms occur:

  • Coughing up blood
  • Croup, a loud barking cough
  • Wheezing
  • Problems breathing, or shortness of breath
  • Chest pain or pressure
  • Mental status changes or confusion
  • Blue or purple lips or nails
  • High fever, usually 103 F or higher for adults
  • Convulsions
  • A fever or cough that will not go away

What are the Best Ways to Prevent the Flu?

You can take many steps to prevent the flu. While you cannot always control if you are around someone who is contagious, you can take precautions to lessen your chances of getting seriously ill. These steps include:

  • Get the flu shot every year
  • Stay away from sick people
  • Cough and sneeze into your elbow
  • Wash your hands often
  • Use hand sanitizer if you do not have access to soap and water to wash your hands

Across the world, plant-based herbal remedies and supplements have also been used to boost immune systems and fight infections like the flu.

Plant-Based Remedies that Fight the Flu

For centuries, people have used natural plant-based remedies to fight the flu and other respiratory diseases. Scientists have been able to analyze the plants and identify many of the chemicals that are thought to bring benefits against the flu. These chemicals include:

  • Polyphenols: A diet rich in polyphenols has been found to protect against disease. Polyphenols derive from phenylalanine or shikimic acid. They protect the plant against infection, stress and radiation. While some polyphenols like quercetin are found in all plants, others are found in specific plants. They have antioxidant effects to help protect cells from damage.
  • Flavonoids: These chemicals are one of the most well-studied groups of polyphenols. They are widely found in fruits and vegetables and have a potent antioxidant effect to prevent cell damage. Flavonoids also have anti-inflammatory properties. Further, they can increase cell enzyme function to protect against disease.
  • Saponins: These compounds occur in many plants. Saponins have a variety of health effects in humans and can help to get rid of mucus in your lungs. They also work as immune boosters and anti-inflammatory agents. Saponins have properties that can kill both fungus and parasites, helping to protect the immune system.
  • Glucosides: These substances, along with glycosides, are a way for plants to store chemicals. Their name refers to the type of chemical bond they form. Many different glucosides exist. Some have anti-inflammatory and antioxidant effects to protect cells from damage.
  • Alkaloids: These chemicals refer to a large variety of plant-based chemicals that contain nitrogen. Some are used for their immune-boosting

A variety of herbs and supplements have been used as folk remedies for centuries and have been shown to fight the flu in small studies. Some of the best data support the use of supplements like:

  • Elderberry
  • Garlic extract
  • Probiotics
  • Echinacea
  • Yeast-based products
  • North American ginseng
  • Pomegranate
  • Selenium
  • Licorice root
  • Guava
  • Seaweed extract
  • Bai Shao (white peony root extract)
