This is the time of year when cold and flu season usually begins. Since the holidays are right around the corner, many people will be traveling to visit family and friends. To stay healthy while traveling during the holidays, it is a good idea to try to strengthen your immune system before you leave. Below are some natural immune system boosters that help prevent you from getting ill.

Echinacea 

Echinacea was originally used for medicinal purposes by North American Plains Indians and homeopathic physicians in Europe. Now it is often used for treating infections and wounds, cold and flu symptoms, strep throat and certain allergies.

This herb is derived from the purple coneflower and helps white blood cells and lymphocytes attack unhealthy organisms in the body. It is available in various forms such as power bars, capsules, teas and liquid extracts.

Sambucus 

Sambucus, commonly known as the elderberry shrub, has blue-black berries that were used to fight cold and flu viruses many years ago. These berries are high in antioxidants that relieve the symptoms of the common cold and the flu. They also help the body produce anti-inflammatory molecules which strengthen its own defense against illness and injuries.

However, the twigs, unripe berries, leaves, seeds and branches are highly toxic when ingested. It is best to obtain the health benefits from sambucus through an over-the-counter supplement that contains the elderberry extract.

Vitamin C 

Vitamin C has always been considered one of the most important nutrients for good health. It protects the body against immune system deficiencies, heart disease, prenatal health problems, eye diseases and keeps the skin looking young and smooth longer.

Vitamin C is available in a wide variety of supplements, multivitamins and energy drinks. It can also be enjoyed in healthy foods such as oranges, strawberries, red peppers, broccoli and dark leafy greens.

Zinc 

Zinc is another natural element that is very important in keeping a healthy immune system. Those who have a zinc deficiency are more likely to suffer from a variety of different illnesses. Taking zinc at the onset of a cold or the flu can reduce the symptoms and help one recover more quickly. 

Zinc is available in both a spray and lozenge form. It is also found in a variety of different foods including seafood, red meat, eggs and nuts.

If you have upcoming travel plans it is also a good idea to get plenty of rest before your trip. Going to bed earlier than usual for a few days before you leave will better prepare you for traveling long distances during the holidays. This also helps strengthen the immune system and will make your visit with family and friends more enjoyable.
