Andrographis: Andrographis (Andrographispaniculata) has been used as a traditional medicine in many parts of Asia, including Thailand and China; it also has a long history of use in Ayurveda, the Indian medical system. In Chinese medicine, this herb is regarded as being ‘cold’, so it is used for what are considered ‘hot’ disorders, such as inflammation, infection and fever. Modern research supports this traditional application, with studies showing that, when compared to placebo, Andrographis helps to reduce the severity and duration of respiratory infections, including the common cold. Note: There have been occasional reports of adverse side effects with Andrographis, such as stomach upset and allergic reactions. If this occurs, stop taking the product and seek medical advice. As with most nutritional supplements, herbs may be contraindicated during pregnancy and breastfeeding and may need to be discontinued in the weeks prior to surgery.
Echinacea: Native to NorthAmerica, echinacea (Echinacea angustifolia) was used by NativeAmerican healers to treat wounds and snakebite. Today, it is recognised as an effective preventive and remedy for flu, colds and upper respiratory infections. It is widely used to restore the body to health quickly while improving the immune system’s natural ability to fight off infections.
Olive Leaf: Olive leaf Widely cultivated in the Mediterranean and more recently in Australia, the leaves of the olive tree (Olea europaea) contain oleuropein. This has many health benefits, including lowering blood pressure and acting as a diuretic, making it useful for treating mild cases of hypertension. Olive leaf is one of nature’s most potent sources of antioxidants, which support the immune system.
Zinc: This mineral is necessary for enzymatic health, which means it is involved in nearly every bodily process and function, from sexual and thyroid health to immune function, skin problems, such as acne, eczema and psoriasis, and correct regulation of insulin levels. Zinc helps to protect the body against colds, flu, bronchitis and other infections. It is especially beneficial for older people because it revitalises the thymus gland, which manufactures immune cells. This mineral may also benefit adults and children with compromised immune systems who are prone to recurrent infection.
Eat a rainbow: Pile your plate high with brightly coloured fruits and vegetables, especially berries, citrus fruit, red onions, spinach and carrots –they’re all rich in vitamins A, C and E, betacarotene and zinc.
Get moving: Just 30minutes a day can help your immune system to fight infection.
Sleep deep: Researchers have discovered that a goodnight’s sleep improves the ability of your immune cells to fight viruses.
Don’t overindulge: Numerous studies have shown that an excessive intake of alcohol will compromise immune function. Think moderation!
Stress less: When stress is chronic and persists over a long period of time, the excess stress hormones circulating in your system will suppress immune function.
Let the sun shine in: Exposing your skin to just 10-15minutes of sunlight a day is enough to ensure your body produces the correct amount of vitamin D – which is essential for the healthy function of the immune system.
Back in the early 1700s, lemons - a rich source of vitamin C - were known to prevent scurvy, a disease that affected sailors. Today, interest in vitamin C is based less on its ability to cure scurvy than on its antioxidant potential to protect cells from damage caused by unstable oxygen molecules called free radicals, and also on its proven immune-boosting powers. We also now know of many food sources of vitamin C that are even more potent than citrus fruits, including baobab, camu camu and acerola. Vitamin C can help to treat the common cold and reduce the severity and duration of symptoms, with one review of 30 placebo-controlled trials finding that high doses of vitamin C shortened the duration of colds by up to four days. Research also suggests vitamin C may even extend life expectancy: one study showed that adults who took over 300mg of vitamin C daily lived longer than those who only had 50mg daily.
