Ward Off and Manage Viral Illness With Herbs


Panic is sweeping China and across the globe with the outbreak of respiratory illness caused by a coronavirus. The number of those affected continues to rise. While the 2019 Novel Coronavirus (2019-nCoV) can be a life-threatening illness, it is also similar to other viral illnesses we’ve witnessed in the past, for example, the swine flu and SARS. While these viruses can certainly be devastating for the individuals and communities directly affected, bear in mind that none of these outbreaks have morphed into the full-blown pandemic that was feared. In fact, there are far more cases of common influenza virus than 2019-nCoV: so far we’ve seen 15 million cases of the flu in the United States this season, with just over 8,000 deaths caused by the flu or secondary pneumonia (Centers for Disease Control [CDC], 2020b); in contrast, there have been 7,700 confirmed cases of the Wuhan virus and 170 related deaths in China as of January 30, 2020 (Mansoor, 2020).

The 2019 Novel Coronavirus, also known as Wuhan virus, is considered a novel virus, meaning it has not been observed in human populations before, although diseases caused by a similar type of virus have been observed, as in the MERs outbreak of 2012. Corona refers to crown-like projections on the individual virions. The earliest infected individuals of the recent outbreak, starting in Wuhan, China, had a connection to a large fish and meat market, suggesting initial animal-to-human transmission. However, it is now apparent that human-to-human transmission has occurred, perhaps carried in mucous droplets from coughs or sneezes (CDC, 2019).

Coronaviruses primarily affect the respiratory system and result in symptoms such as fever, cough, and shortness of breath, and many of those infected recover without serious complications. In some cases, however, the virus can progress to include symptoms similar to pneumonia and bronchitis, particularly in small children, the elderly, or those with chronic respiratory diseases, which are some of the larger concerns associated with this outbreak. Because a coronavirus vaccination is not available at this time and there is not a magic-pill cure, medical care is necessary. Anyone who thinks they may be infected with 2019-nCoV should seek the care of medical doctors who will test for the virus, manage the symptoms (often at home, but sometimes in the hospital, if warranted), and monitor the patient throughout the duration of the illness. 

Likewise, because this particular virus has never been seen before, and there is not enough information yet about how it compares to any virus with a longstanding history of infecting humans, information about herbs that have been called “antivirals” in other contexts may or may not be applicable to this virus.   

The best approach to addressing concerns about 2019-nCoV, or any viral illness for that matter, starts with prevention and building your immunity during this season. Below you’ll find some tips to help ward off and manage viral illness with herbs.

5 Tips to Help Ward Off and Manage Viral Illness With Herbs

Tip #1: Prevention Is Key!

When it comes to avoiding a viral infection, the following preventative measures will go a long way in helping you avoid contracting a virus.

washing hands

Hygiene & Avoidance Prevention

Here are some things you can do proactively (CDC, 2019)

  1. Simple hygiene is one of the best ways to protect yourself. Wash your hands using soap and water, scrubbing for at least 30 seconds. Alcohol-based hand sanitizer is a good alternative if you can’t wash, but it’s less effective than old-fashioned soap and water. Avoid touching your eyes, mouth, or face. 
  2. Stay home if you are sick, and avoid contact with those who are ill, especially if you are immune-compromised. 
  3. Disinfect frequently touched surfaces like doorknobs, light switches, and faucets.
  4. Understand the symptoms and risks. The main symptoms of 2019-nCoV are a fever with signs of lower respiratory infection such as cough and difficulty breathing. Those considered at increased risk for 2019-nCoV are those who have traveled to the Wuhan region within the last 14 days or have been in close contact with someone who has the virus. The general United States population is currently considered to be at low risk from this virus (CDC, 2020a).

healthy food

Dietary Prevention

We can’t speak about avoiding viral illnesses without mentioning diet! One of the best ways to stay well during cold and flu season, or any time of the year for that matter, is to have a healthy, nourished body. One way to do that is by adopting good dietary practices. 

Eating a whole food diet is best. That means avoiding processed foods and instead opting for foods with high nutritional value. It may also mean cooking at home more often or only eating out at restaurants that make their meals from scratch. 

Being choosy about the types of foods you eat as this will go a long way toward nourishing your body. If you consume meat and dairy products, choose high-quality sources that are humanely raised instead of less expensive options that may come from less healthy animals. Cut back or eliminate sugar and alcohol from your diet as both are known to suppress the immune system. Fill your plate with fruits and vegetables free of chemicals and pesticides, and incorporate fermented or cultured foods into your diet to support gut and immune health. All of these suggestions are ways to nourish your body so it is healthy and thus better able to fend off illness or recover after an illness.

Building and Protecting the Immune System With Herbal Immunomodulants, Immune Stimulants, and Antivirals

Incorporating immunomodulant, immune stimulant, and antiviral herbs can help to build, protect, and support your immune system in the long-run.

Immunomodulant Herbs

Immunomodulants support immune function and can be used to keep your immune system humming. These are a great idea throughout the cold and flu season. Choose from among herbs that are generally considered safe, such as tonic herbs with this action. Keep in mind immunomodulant and tonic herbs are valued for gentle, general, and slow, long-term benefits, and are not considered an emergency response or any kind of cure.     

edible mushroom

One really great category to look to for ongoing support is the immunomodulant mushrooms. There are several mushrooms that are generally safe and may improve the immune system’s function (e.g., reishi (Ganoderma spp.), turkey tail (Trametes versicolor), and maitake (Grifola frondosa)). The presence of special complex polysaccharides within these mushrooms seems to encourage a healthy immune response. These may be used every day when one is well—think of these tonics as a potential part of a seasonal daily routine (Stamets, 2002).

Astragalus (Astragalus membranaceus) root is an herb that is used much in the same way as the immunomodulant mushrooms. Astragalus root also contains complex polysaccharides that have been shown to improve immune activity, specifically by increasing the activity of white blood cells, stimulating adrenal-cortical activity, and encouraging red blood cell formation in the bone marrow. However, note that there is a traditional practice of not using astragalus during acute illness (Hoffmann, 1993).

Immune Stimulant Herbs

Let’s say that you have no choice but to engage in air travel, or you or someone in your household works in an environment that either travelers or sick people pass through. In addition to conventional wisdom, is there anything more one can do?!  Some herbs are called immune stimulants because they are believed to temporarily increase a non-specific response called surface immune activation. This refers to the detection of unfamiliar proteins and can help alert the rest of the immune system that something unfamiliar is present. 

Garlic close up on paper

Echinacea (Echinacea spp.) root is a great example of an immune booster that walks the line between “immunomodulant” and “immune stimulant.” It’s a particularly useful herb to add to your daily routine if you’re concerned that you’re at risk for viral infection—for example, if you’re about to travel by plane, train, or bus! Some herbal wisdom suggests reserving it for these occasions, differentiating the use of echinacea from the use of the immunomodulant mushrooms, for example (Katz, 2013). 

Garlic (Allium sativum) bulb is another familiar immune stimulant herb (Bergner, 1996). No matter where you are you can almost always find garlic, including if you are traveling abroad or stuck at home.

Antiviral Herbs

Elder (Sambucus nigra, S. canadensis, or S. cerulea) berry is a gentle antiviral herb that has been called upon as a longstanding folk remedy during outbreaks of the flu. Some consider it a preventive to be taken throughout flu season (Buhner, 2013; Zakay-Rones et al., 2007).

licorice root tea

Licorice (Glycyrrhiza glabra) root teas, lozenges, or tinctures may also be a good idea in winter months for some of the same reasons. Licorice is an immunomodulant and antiviral, and it is moistening, supporting the mucosa of the mouth and throat. Additionally, licorice may have some anti-inflammatory activity. Those with high blood pressure should avoid this herb and choose from among the others (Buhner, 2013).

Tip #2: Feeling Sick? Go to the Doctor!

Any time there is a new or unusual infection circulating, any person with characteristic symptoms should contact a conventional medical provider for an assessment about how to proceed. When a novel virus is in the news, infectious disease specialists and care providers request that individuals call medical facilities for instructions on how to protect others while seeking assessment and care. 

It is of utmost importance to seek the assessment and care of licensed professionals. Many times, lab tests will be performed to confirm a viral illness. If these tests come back positive, your doctor may advise you to manage common symptoms at home, with little more instruction than to use hot tea, expectorants, and fluids (sometimes prescribing stronger medications if needed), and to follow up with them at a certain date or if your symptoms worsen. Other times, depending on signs and severity, your doctor may advise in-hospital supervision or advanced care.

Tip #3: At-Home Symptom Management

If you have received a positive diagnosis for a viral illness and have been cleared by your doctor to manage symptoms at home, chances are, your doctor has provided information on how to manage common symptoms of a viral illness at home. If you are interested in using herbs to support your body during this time, talk with your doctor about your plans. 

Many herbs can help to soothe cold and flu symptoms; some of these may also offer some of the immune-supportive actions mentioned in sections above. Here are some of our favorites: 

Tulsi (Ocimum tenuiflorum) aerial parts (also called holy basil) is a pleasant-tasting, generally safe herb that makes a wonderful tea. Tulsi tea can be anticatarrhal, warming, soothing, anti-inflammatory, gently lifting to mood and energy without being stimulating, and some sources even call it an antiviral herb (Wood, 2008). This is also a sound choice for simple at-home care as it is available as a boxed tea and is widely consumed as a food item with very few adverse events reported. Tulsi is also featured in our Cold and Flu ebook

marshmallow root

Demulcent herbs can be especially soothing to the irritation of a dry or relentless cough. Marshmallow (Althaea officinalis) leaf or root is extremely demulcent in cool-water infusions. Licorice (Glycyrrhiza glabra) root also has demulcency and there are many other herbs with this quality. Linden (Tilia spp.) bract and flower is one of the gentle demulcent herbs that is also used as a pleasant, soothing tea. Learn more about linden in a blog feature on using this gentle and effective herb.

Expectorant herbs can be supportive during any kind of cold or flu. Highly aromatic herbs such as eucalyptus (Eucalyptus spp.) leaf or thyme (Thymus spp.) leaf can be used in herbal steams or atomizers, and gentler aromatic herbs such as peppermint (Mentha x piperita) leaf or hyssop (Hyssopus officinalis) aerial parts can help release excess mucus when used as teas or herbal steams. Find out how to do an herbal steam as well as which other herbs can be used as expectorants: Breathe Easier with a Decongesting Herbal Steam.

Symptoms such as a fever, sore throat, and a cough are also common symptoms of many viral infections, and supportive herbal recipes for these symptoms can be found in our Cold and Flu ebook.

Tip #4: Give It Time

Sometimes you get an assessment from a medical professional, follow their recommendations, and are vigilant about self-care, rest, immune support, and medical follow-up, and still, your cold or flu seems to last longer than expected. If you have concerns about your illness, visit your doctor for a follow-up. However, if you are assured it is not a serious or life-threatening condition and are advised to continue the common tea, fluids, and rest regimen, but your body just isn’t fighting it in due time, here are a few additional herbs to consider.  

pine needles

Resinous herbs like the needles or sap from certain species in the Pinaceae (pine) family have strong expectorant and antiseptic actions. Propolis, the resinous substance produced by bees, has similar properties. These resins should be used in small amounts, both for the sustainability considerations of propolis and because larger amounts can cause nausea. A few drops of propolis tincture at a time, diluted in a quarter ounce of warm water, can help protect and soothe the throat and transfer some antiseptic properties. For tree resins or tincture of white pine (Pinus strobus) needle, a typical dosage is around ¼ to ½ mL tincture (5-10 drops) at a time diluted in a bit of warm water. You can harvest resin from almost any species of true pine, but making resin tincture is a very messy task that’s best done while you’re still in good health—so if you don’t have it on hand before you get sick, you may want to skip this one!

Some pine needles such as those from white pine (Pinus strobus) can be made into a strongly expectorant and mildly antiseptic herbal tea. Infuse a handful of chopped needles into 2 cups of boiling water, then steep, covered, for 10 minutes. Consume to tolerance for taste. 

Boneset (Eupatorium perfoliatum) is one of the surprising very common herbs that has been used for cold and flu support, and there is research to support its use as an adjuvant during infection. The aerial parts (leaf and flower) are used in tea or tincture. Boneset is also strongly diaphoretic and has been traditionally used to help “break” a high fever, so you might think of it only for early on in colds and flu but it can additionally be helpful later. It is alarmingly bitter, but consider the following: though the research is limited, there is support for boneset’s activity against influenza A (H1N1), and its anti-inflammatory action is supportive when respiratory irritation lingers (Buhner, 2013). Herbalist Stephen Buhner writes about one specific indication for boneset’s use for respiratory irritation: “When the acute stage has passed but there is continued chronic fatigue and relapse, take 10 drops of tincture in hot water 4x daily” (Buhner, 2013, p. 248).

Old and new wisdom about viral infections such as colds and the flu suggests keeping the body warm, with the exception of managing especially high fevers acutely. Herbalist wisdom, whether guided by old doctrines or contemporary voices in Western herbalism, suggests generally using herbs with a warming and drying nature to support the body in driving off viral infections that last. Boneset is sometimes considered cooling, but it seems to have a diaphoretic action that initially warms and then ultimately cools the body. If using herbs with a cool nature, be sure to combine with some warming herbs, or warm baths, warm attire, and warm environment.     

Lomatium (Lomatium dissectum) root is a potent and effective antiviral that is warming and drying in part due to a resinous property. However, this is the kind of herb one might reserve for the instance of a novel or exceptional viral infection because it is not abundant, its range is limited, and the root is the part used. It is on the United Plant Savers’ “At-Risk” list of wild herbs under exceptional harvesting pressure (United Plant Savers, 2018). If a household were affected by a novel virus and advised to do care at home under medical supervision, and this herb was in ones’ home apothecary, this would be the time to pull it out. Typically, it has been prepared as a tincture, and used in small amounts regularly, ½ ml several times throughout the day while affected (Buhner, 2013). Small amounts of herbal tea infusion would have a similar effect but the taste is quite strong!

ginger root tea

There is another more familiar herb, more likely to be found in cabinets and apothecaries already, and more available for regular use during typical colds and the flu. Ginger (Zingiber officinale) rhizome (available at the grocery store!) could be considered somewhat analogous to lomatium root. In particular, ginger is a warming, drying, and antiviral root (Buhner, 2013). It can be made into an herbal tea by simmering slices of the fresh root in water or via the fresh ginger tea recipe in our Cold and Flu Season ebook. It can also be used as a tincture. Herbalist Stephen Buhner suggests using it every 60 minutes when using as an antiviral and indicates that the juice freshly squeezed from the rhizome is particularly potent (Buhner, 2013).     

Antibacterial Backup

Additionally, antibacterial herbs may be added, as raw irritated mucosal tissue from coughing and sneezing may be more susceptible to secondary bacterial infections. A few antibacterial herbs that are used to support the respiratory tract include Oregon grape (Mahonia spp.) root (sustainably wild harvested or cultivated), barberry (Berberis spp.) root, and oregano (Origanum vulgare) leaf (Birdsall & Kelly 1997; Stermitz et al., 2000, Kintzios, 2002). Similar to the resinous herbs mentioned above, these herbs are also very strong in flavor and action. Small amounts of tincture are often taken for acute use, or small amounts or infusion can be drunk if the taste is tolerated. These herbs are also available as encapsulated products. 

These are certainly not the only herbs with antibacterial potential. These are standouts because they are considered strong relative to many other herbal choices and have additional expectorant and anti-inflammatory action.

In Closing

Because so little is known about the 2019 Novel Coronavirus, all of the herbs mentioned above should only be considered wellness-supporting herbs during cold and flu season, and not protection or a cure in the event of exposure. 

While prevention and herbal support can go a long way in providing your body some extra protection from viral illnesses, it does not guarantee you will not contract a virus if you are exposed to it. However, incorporating herbs into your wellness plan—before, during, and after an illness—can help to decrease the severity and duration of an illness and to help support the body in recovery.
