Infection (Holistic)

About This Condition

Protect your body from infection—the invasion of microorganisms. The best defense? A strong immune system. According to research or other evidence, the following self-care steps may be helpful.

See a healthcare provider
Except for common infections such as a cold, see your provider for help determining the cause and best treatment for your infection
Take a multivitamin
Extra vitamins and minerals daily may help prevent deficiencies that increase your chances of getting an infection
Reduce stress
Work with a counselor or with tapes and other self-help tools to reduce stress, which can impair your immune system

About

Infection is the result of invasion of the body by microorganisms, including bacteria, viruses, or fungi.

Not all microorganisms cause infections in the body, and exposure to a disease-causing microorganism does not always result in symptoms. The immune system plays a large role in determining the body’s ability to fight off infection.

Some examples of infection are Reference common cold/sore throat, Reference influenza, Reference cough, Reference recurrent ear infections, Reference urinary tract infection, Reference yeast infection, Reference athlete’s foot, Reference cold sores, Reference HIV, Reference shingles, and Reference parasites.

Symptoms

Symptoms of infection include localized warmth, redness, swelling, discharge, foul-smelling odor, and Reference pain to the touch. In more serious cases, symptoms may also include fever, chills, nausea, vomiting, Reference diarrhea, and fatigue.

Healthy Lifestyle Tips

Stress can depress the Reference immune system, thus increasing the body’s susceptibility to infection. Coping effectively with stress is important.¹ Exercise increases natural killer cell activity, which may also help prevent infections.²

Eating Right

The right diet is the key to managing many diseases and to improving general quality of life. For this condition, scientific research has found benefit in the following healthy eating tips.

Recommendation	Why
Balance nutrition	Nutrition contributes to proper immune system function, so support it by restricting sugar, drinking alcohol moderately or not at all, and eating less fat. Nutrition is a major contributor to the functioning of the immune system, which in turn influences whether or not the body is resistant to infection. Specifically, it makes sense to restrict sugar, because sugar interferes with the ability of white blood cells to destroy bacteria.³ Alcohol also interferes with a wide variety of immune defenses,⁴ and excessive dietary fat reduces natural killer cell activity.⁵ However, there is no research investigating whether reducing sugar, alcohol, or fat intake decreases the risk of infection or improves healing.
Uncover your allergies	Food allergies can play a role in recurrent infections. An elimination diet may help you discover sensitivities. Reference Allergy , including food allergy, has been suggested to predispose people to recurrent infection,⁶ and many doctors consider allergy treatment for people with recurrent infections. The links between allergy and Reference ear infections,⁷ ^{, 8} Reference urinary tract infections in children,⁹ and Reference yeast vaginitis in women¹⁰ ^{, 11} have been documented.

Supplements

What Are "Star" Ratings?

Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.

For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

3 Stars Reliable and relatively consistent scientific data showing a substantial health benefit.

2 Stars Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.

1 Star For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

Supplement	Why
3 Stars Andrographis 48 to 60 mg andrographolides in two to three divided doses per day	Andrographis supports the immune system and protects against microbes. Herbs that support a person’s Reference immune system in the fight against microbes include the following: Reference American ginseng, Reference andrographis, Reference Asian ginseng, Reference astragalus, coriolus, Reference eleuthero, Reference ligustrum, Reference maitake, Reference picrorhiza, Reference reishi, Reference schisandra, and Reference shiitake. Double-blind trials have shown that common cold symptoms improve¹² ^{, 13} and recovery is faster¹⁴ when andrographis extract containing 48 to 60 mg andrographolides is taken in three or four divided doses daily, beginning as soon as possible after symptoms appear. In addition, preliminary research in Russia suggests andrographis extract may be effective for the treatment of influenza.¹⁵ This extract was also tested for preventing colds in a double-blind study of teenagers.¹⁶ After three months, the group taking 5 mg of andrographolides twice daily had only half the number of colds experienced by the placebo group. Other preliminary¹⁷ and double-blind¹⁸ ^{, 19} research has shown similar benefits for treating the common cold from a combination of andrographis extract and an eleuthero extract containing 2.0 to 2.4 mg per day eleutherosides.
3 Stars Vitamin A See a doctor for evaluation of possible deficiency	Vitamin A plays an important role in immune system function and helps mucous membranes, including those in the lungs, resist invasion by microorganisms. Nutrients useful for maintaining healthy immune function are also applicable for preventing infections. Reference Vitamin A plays an important role in immune system function and helps mucous membranes, including those in the lungs, resist invasion by microorganisms.²⁰ However, most research shows that while vitamin A supplementation helps people prevent or treat infections in developing countries where deficiencies are common,²¹ little to no positive effect, and even slight adverse effects, have resulted from giving vitamin A supplements to people in countries where most people consume adequate amounts of vitamin A.²² ^{, 23} ^{, 24} ^{, 25} ^{, 26} ^{, 27} ^{, 28} Moreover, vitamin A supplementation during infections appears beneficial only in certain diseases. An analysis of trials revealed that vitamin A reduces mortality from Reference measles and Reference diarrhea, but not from pneumonia, in children living in developing countries.²⁹ A double-blind trial for vitamin A supplementation in Tanzanian children with pneumonia confirmed its lack of effectiveness for this condition.³⁰ In general, parents in the developed world should not give vitamin A supplements to children unless there is a reason to believe vitamin A deficiency is likely, such as the presence of a condition causing Reference malabsorption (e.g., Reference celiac disease). However, the American Academy of Pediatrics recommends that all children with measles should be given high-dose vitamin A for several days.
3 Stars Vitamin C 1 to 4 grams daily	Vitamin C has antiviral activity, and may help prevent viral infections or, in the case of the common cold, reduce the severity and duration of an infection. Reference Vitamin C has antiviral activity, and may help prevent viral infections³¹ or, in the case of the Reference common cold, reduce the severity and duration of an infection.³² Most studies on the common cold used 1 to 4 grams of vitamin C per day.
2 Stars Echinacea 3 to 5 ml of liquid herbal extracts every two hours, or 300 to 600 mg of powdered herb three times per day, or 5 to 6 cups of tea daily	Echinacea is both immune supportive and antimicrobial. Herbs that support a person’s Reference immune system in the fight against microbes and directly attack microbes include the following: Reference barberry, Reference echinacea, Reference elderberry, Reference goldenseal, Reference licorice, Reference Oregon grape, osha, and Reference wild indigo.
2 Stars Multivitamin Follow label directions	A multiple vitamin-mineral formula helped elderly people avoid infections in one double-blind trial. A Reference multiple vitamin-mineral formula helped elderly people avoid infections in one double-blind trial, but not in another.³³ ^{, 34} In a double-blind study of middle-aged and elderly diabetics, supplementation with a multiple vitamin and mineral preparation for one year reduced the risk of infection by more than 80%, compared with a placebo.³⁵ In another double-blind trial, supplements of 100 mcg per day of Reference selenium and 20 mg per day of Reference zinc, with or without additional Reference vitamin C, Reference vitamin E, and Reference beta-carotene, reduced infections in elderly people, though vitamins without minerals had no effect.³⁶ That study suggests that trace minerals may be the most important components of a multiple vitamin and mineral formula for preventing infections.
2 Stars Multivitamin (Type 2 Diabetes) Follow label instructions	Supplementing with a multivitamin–mineral may give your body the nutrients it needs to help prevent common infections. In a double-blind study, supplementation of middle-aged and elderly diabetics with a multiple vitamin and mineral preparation for one year reduced the risk of infection by more than 80%, compared with a placebo.³⁷
2 Stars Probiotics Consult a qualified healthcare practitioner	Lactobacillus acidophilus produces acids that kill invading bacteria. These and other probiotics inhibit the growth of potentially infectious organisms and have been shown to be effective against some infections. Reference Lactobacillus acidophilus (the friendly bacteria found in yogurt) produces acids that kill invading bacteria.³⁸ The effective amount of acidophilus depends on the strain used, as well as the concentration of viable organisms. These and other friendly bacteria known as Reference probiotics inhibit the growth of potentially infectious organisms (pathogens) by producing acids, hydrogen peroxide, and natural antibiotics called bacteriocins and microcins, by utilizing nutrients needed by pathogens, by occupying attachment sites on the gut wall that would otherwise be available to pathogens, and by stimulating immune attacks on pathogens. Infections that have been successfully prevented or treated with friendly bacteria include infectious Reference diarrhea, Reference vaginitis, and Reference urinary tract infections.³⁹ ^{, 40}
2 Stars Selenium 100 mcg per day with 20 mg per day of zinc	Selenium supplements have been reported to help reduce infections in elderly people. Most,⁴¹ ^{, 42} but not all,⁴³ double-blind studies have shown that elderly people have better immune function and reduced infection rates when taking a Reference multiple vitamin-mineral formula. In one double-blind trial, supplements of 100 mcg per day of Reference selenium and 20 mg per day of Reference zinc, with or without additional Reference vitamin C, Reference vitamin E, and Reference beta-carotene, reduced infections in elderly people, though vitamins without minerals had no effect.⁴⁴ Burn victims have also experienced fewer infections after receiving trace mineral supplements in double-blind research.⁴⁵ These studies suggest that trace minerals may be the most important micronutrients for enhancing immunity and preventing infections in the elderly.
2 Stars Zinc Refer to label instructions	Zinc deficiencies can impair immune function. Supplementing with zinc has been shown to increase immune function in healthy people. Zinc lozenges have been found helpful in against the common cold. Marginal deficiencies of Reference zinc result in Reference immune function impairments.⁴⁶ In a double-blind study of healthy elderly people, supplementing with 45 mg of zinc per day for one year significantly reduced the frequency of infections.⁴⁷ Some doctors recommend lower amounts of supplemental zinc for people experiencing recurrent infections, such as 25 mg per day for adults and even lower amounts for children (depending on body weight). Zinc lozenges have been found helpful in some studies for the Reference common cold. Long-term zinc supplementation should in most cases be accompanied by a copper supplement in order to prevent zinc-induced copper deficiency.
