New research shows that many of the most severe cold and flu symptoms result from an imbalance in the body’s immune system. This research suggests that cold and flu patients benefit substantially from doses of specific immune-boosting nutrients. Here are the best all natural remedies for cold and flu:
1. Drink lots of fluids
Fluids are essential because they help to keep mucous membranes moist. Mucous is the body’s first line of defense against germs and viruses, so mucous membranes must stay wet to prevent the spread of cold and flu viruses effectively. Staying hydrated when you have a cold or flu is important because water, broth, and teas help to flush out toxins that cause colds and fly, as well as promote optimal digestion, the source of the body’s natural immunity.
2. Take vitamin C
A study published in the journal BioFactors found that older adults who took 1,500 mg of vitamin C daily for three months suffered less from viral infections than those who did not take vitamin C. Vitamin C boosts immune function and fights harmful free radicals, which damage healthy cells and increase vulnerability to bacterial and viral infections. In addition, vitamin C helps to relieve cold and flu pain by calming the nerves, and helps dissolve mucus, making it easier to cough up mucus that has built up in the airways due to colds and flu.
3. Ginseng
A 2012 study found that ginseng preparations significantly reduced cold symptoms, including fever and cough. It also helped to shorten the duration of the most severe symptoms. Ginseng not only helps to boost immune function and protect red blood cells from damage by free radicals—it also helps to reduce high cholesterol levels and improve heart health, which is essential for a robust immune system to fight off future infections.
4. Bone broth
A 2012 study found that bone broth effectively killed the influenza virus in cell cultures. It is rich in collagen, which strengthens connective tissue, including mucous membranes in the body, which line airways and the digestive tract where most cold viruses begin to invade the body. Bone broth is super high in minerals that boost immune function and help to balance blood sugar levels, and it contains various other nutrients that promote overall health and well-being, including calcium and magnesium.
5. Honey
Many people believe that eating raw honey can help prevent colds and relieve symptoms of a cold once it has taken hold. A study from the University of Northumbria in the UK found that eating at least one teaspoon daily reduced the number of colds by 50 percent. Honey helps to regulate immune function while stimulating circulation and improving oxygen flow through the lungs, which supports healthy immune function.
