9 Natural Plant-Based Remedies That Can Boost Immunity

Did you know that before there were any medications made in scientific labs, plants were the ONLY source of natural healing? There are many ancient healing plant-based medical treatments that stem from Ayurveda, Traditional Chinese Medicine (TCM), and Native American cultural practices. Plants were the only source of medical treatment before synthetic medications were developed (many of which started with plants). Until recently, only anecdotal evidence has existed to support the use of plant-based alternatives for medical treatment. However, now that many hospitals and universities are recognizing, and even embracing, the benefits of ‘alternative’ treatment, research on the use of plant-based medicine for natural healing is now emerging. More than 40% of Americans now turn to natural plant-based therapies in addition to traditional western medicine.

As you know, one of the backbones to staying healthy is to keep your immune system robust and strong. Here are some common kitchen staples that can be incorporated into your daily routine to help naturally prevent nasty colds, annoying infections and debilitating viruses.

Turmeric: Curcumin, the active ingredient in turmeric not only lends to its beautiful orange-hue, but it’s also been shown to be a potent immune enhancing substance through its anti-viral, anti-fungal and anti-cancer properties. Dosage: Take 400 to 600 mg of turmeric extract (available in tablets or capsules) three times per day. Whole turmeric is more effective than isolated curcumin. The dosage for the whole root is 1.5 to 3 g per day or 1-3 g per day of the dried, powdered root. For best absorption, take it with black pepper and/or healthy fats.

Cayenne: Capsaicin, the main phytochemical in cayenne, is a great source of carotenoids, including beta-carotene. Carotenoids are powerful antioxidants that can help ward off free radical damage and support healthy immune function. Cayenne is also rich in Vitamin C, which fights and prevents colds and other infections. Vitamin C contains bioflavonoids, which the body needs to produce white blood cells, the disease-fighting component of the blood that helps to fight infection. Dosage: Add a teaspoon (or more if you like your food hot!) to meals. Two teaspoons of cayenne pepper provide 28% of the recommended daily value for vitamin A and 4% of the recommended daily value for vitamin C.

Oregano spices

Oregano: Carvacrol and thymol are essential oils in oregano that contain fungicidal and anthelmintic (ability to destroy internal parasites) properties. Dosage: Taking the emulsified oil of oregano orally 200 mg three times a day for six weeks has been shown to eradicate intestinal parasites.

Ginger tea

 Ginger: Ginger has been touted as a digestive and immune-enhancer backed by strong research. Ginger helps to open up the lymphatic system and prevents the build-up of toxins that may create infections. Ginger also helps to activate T-cells, which are vital to a healthy immune system and destroy viruses. Dosage: For inflammation, use 125 to 1000 mg (1 gm) three to four times a day. One quarter-inch slice of fresh ginger is equal to 1 to 2 gm of powder.

 Garlic: Garlic offers protection against many bacterial and viral infections. In order to stimulate the release of the enzyme allinase, fresh garlic must be crushed or chopped. Allinase then turns into allicin, which contains the disease fighting characteristics. Dosage: The recommended daily dose of allicin is 8 mg, equivalent to about 4 gm or 1 clove of fresh garlic.

 Lemon/Lime: Flavonoids and terpenoids (limonene) are plant substances present in lemons and limes that possess anti-viral, anti-microbial, anti-inflammatory and anti-allergenic potential. The flavonoids also enhance the antioxidant capacity of vitamin C and act as powerful anti­oxidants. Dosage: Squeeze lemon or lime juice on salads, veggies or any hot meal to add a little zest plus vitamin C to serve as a natural immune-booster.

Green Tea: Epigallocatechin gallate (EGCG) is the plant compound, or catechin, found in green tea that may exert antiviral and cancer-fighting effects. Numerous studies have been conducted evaluating the effects of green tea on certain types of cancer. Many studies have shown protective benefits of green tea against colon, breast, esophageal, and ovarian cancer. Dosage: Since there are many variables involved in each study, there has not been one standard recommendation for green tea consumption. Most studies have safely demonstrated that between 1 and 4 cups of green tea daily may contribute to health benefits.

Probiotics: Probiotics help to restore balance to the natural gut flora, which naturally stimulates the immune system. Probiotics are beneficial organisms such as bacteria or yeast that improve intesti­nal microbial balance. They work by re-colonizing the gut and inhibiting the growth of pathogenic organisms. Dosage: When taking probiotic supplements, there is no set dosage since there are so many different probiotic organisms. Many probiotic supplements are dosed by the number of live organisms they contain. For instance, a typical dosage of Lactobacillus acidophilus ranges between 1 billion to 10 billion live organisms split into three or four doses. You can get probiotics naturally by consuming fermented foods such as kimchi, miso, tempeh, and kombucha.

Prebiotics: Prebiotics are like ‘food’ for probiotic strains. Prebiotics promote the growth and/or activity of certain types of healthy bacteria, helping to reduce undesirable pathogens or unhealthy organisms. Dosage: You can find prebiotics naturally in Jerusalem artichokes, chicory root, garlic, leeks, banana, onion, barley, wheat flour, rye, tomato, and asparagus root.

Elderberry: Elderberries contain natural substances called flavonoids that may help reduce swelling, fight inflammation, and boost the immune system. Studies have found that elderberry may ease flu-like symptoms such as fever, headaches, fatigue, sore throat, cough and body aches. The benefits appear to be greatest when elderberry is started within 24 to 48 hours within the onset of symptoms. Dosage: There is no standard dose of elderberry. Some studies have used 1 tablespoon of an elderberry syrup extract four times a day to treat flu symptoms. Also available are elderberry lozenges, often paired with zinc, which may be taken throughout the day once a cold begins.
