Can we influence our immune system? Are there any herbal immunity boosters out there? What foods can help me strengthen my immunity? As the Corona Virus threatens the health and even the lives of the most vulnerable amongst us, many are asking these kinds of questions.
Especially those with less than optimal immunity – chronically sick, cancer patients, pregnant women, and the elderly – are at the highest risk of contracting and potentially dying from the disease.
Rather than panicking, we should take steps as individuals and as societies to protect ourselves and our loved ones from the results of a potential infection. One sure way to improve our odds is to fortify our immune system by employing herbal immunity boosters and other natural ways.
Aside from taking common-sense preventative measures such as handwashing, avoiding mass events, not touching our face, nose, and mouth; we can attempt to strengthen our immunity by consuming immunity-boosting foods, herbs, and minerals, and adding some other modalities to protect ourselves.
First of all, let’s establish what is the immune system and how does it work. The immune system is the first line of defense that the body has against a microorganism that might enter it. Our immune cells are designed in such a way that they, if functioning properly, can easily discern what is “self” and what is “other,” and then act accordingly, neutralizing the stranger and hence protecting us from a full-blown illness.
The human immune system is made up of various organs, the lymphatic system, and individual cells and proteins. The surface on the outside of our body (skin, hair) is there to offer the first barrier to alien microorganisms, while on the inside, we have very smart mucous membranes that act as protection against the germs that enter the body. The stronger your immune system, the lesser chance of you falling ill.
The human immune system is highly complex. There are varied immunity cells that either circulate throughout the body or reside in a particular spot. Each type of immunity cells plays a role against a specific type of pathogens.
For example, as this NIH study explains, basophils and eosinophils are important for host defense against parasites and are also involved in allergic reactions.
Neutrophils, on the other hand, patrol for problems by circulating in the bloodstream and can literally ingest bacteria when they detect them.
Natural killer (NK) cells are important for recognizing and killing virus-infected cells or tumor cells.
There are also B cells and T cells that can adapt to the specific danger and neutralize the antibodies that the pathogen creates to avoid detection. Read a more in-depth analysis of the different kinds of immune cells here.
Can We Boost Our Immunity Naturally?
A healthy immune system reduces the chances of viral and bacterial infections and flu and possibly the new coronavirus. Adopting some natural ways to boost this system of protection you can increase your immunity and prompt a better response of your immune system to possible infections.
From better sleep to eating a balanced diet and increasing physical activity, there are simple yet proven ways to increase the body’s strength and responsiveness against the encroaching microorganisms.

There are many foods and herbs that can bolster your immune system. Here are just a few:
1. Elderberry: The Old School Protection
Elderberry or Sambucus nigra is a bush or shrub whose fruit is used to make tinctures, syrups, and lozenges. The humble elderberry has antiviral, anticancer, and anti-inflammatory properties and it is also very high in flavonoids and vitamins.
Elderberry syrup or tincture has been known for centuries as a remedy for colds, the flu, and other viral and bacterial infections. Basically, the compounds present in the fruit can reduce the swelling in mucus membranes and can thus help the mucous layers act as a protective barrier against the germs.
Elderberry Syrup Recipe
Here is a simple recipe for an elderbery syrup froma trusted source, Mountain Rose Herbs:
If it’s too much hassle to make your own – I get it, we are all busy – you can get an excellent quality syrup from a trusted source like
Equinox Elderberry Syrup Plus!
from: Starwest Botanicals Inc.
Even though the elderberry has so many benefits, it is important to remember that there are some interactions with other remedies and medicines (such as diuretics, laxatives, steroids, and chemotherapy amongst others.) Always check with your medical team before adding any new remedy to your regimen.
2. Small but Mighty: Mushrooms for Immunity and Health
Mushrooms of all kinds (button mushrooms, portabella, shitake, Chaga, reishi, etc.) are high in all kinds of B vitamins (most importantly riboflavin and niacin), polysaccharides, and selenium, all of which are crucial for the immune system to remain in optimal form. You can add mushrooms, or fungi, to your diet in so many forms:
- Add them to omelets and scrambled eggs.
- Use them as pizza topping.
- Make a mushroom soup or just add them to other soups, stews, or salads.
- Make a mushroom burger in place of a meat burger.
- Stuff them to make an interesting and healthy snack or finger food for your next party.
3. Enjoy Watermelon Not Only in the Heat of the Summer
Watermelon is probably one of the best tasking immune-boosting foods. It is a great source of vitamins A, C, and B6, glutathione, and potassium. It’s also not very high in calories, although most of its calories are from sugar, so it must be consumed with caution if you’re a diabetic or watching the GI-index of your food.
4. Make Plain Yogurt Your Friend
Around two-thirds of your body’s entire immune cells are found in the gut walls. To keep your gut in top form, so that it can also metabolize and remove bodily toxins, try adding plain yogurt on a daily basis to your diet.
Aside from being an excellent source of protein, vitamin B12, and vitamin B2, plain yogurt is crucial for providing the body with vitamin D and other nutrients that are necessary for strong immune function.
Most importantly though, plain yogurt can provide you with probiotics such as Lactobacillus acidophilus, Lactobacillus casei, and Bifidus, all of which will bolster the immune function of your gut. Beneficial gut flora is crucial for proper digestion and detoxification, in addition to helping establish a robust immune function.
I make my own using heirloom live cultures from Cultures for Health.
5. The Green Monster: the Mighty Spinach
Spinach is a veggie that has one of the highest contents of fiber, folate, vitamins A and C, iron, and magnesium. The nutrients in spinach not only boost immune function but may also improve cell division and DNA repair. In order to get the most out of spinach, it is best consumed raw (in salads) or just lightly sautéed to keep the nutrients intact. It is also a delicious ingredient for green juices.
6. Drink Tea (Especially Green Tea)
I wrote elsewhere about the benefits of tea, especially the delicious superfood, matcha green tea. Not only is tea (white, green, black, or oolong) delicious and a great way to help you hydrate your body, but it is also high in polyphenols.
The two most important polyphenols in tea are ECGC – the powerful antioxidant – and the amino acid L-theanine. These compounds have the ability to naturally boost T cell activity and therefore prime your immune system to respond robustly to any incoming challenge.
