5 Immune-Boosting Natural Remedies

March 26, 2020 12 Comments

“Health is a treasure. Of all temporal possessions it is the most precious.”

-Ellen G. White, Counsels on Diet and Foods.


Herbal remedies have been around for centuries and have been found by many natural healers to be valuable in their immune-boosting and medicinal use. 

In this natural remedy video we share with you Modern Manna’s version of an immune-boosting tea, you many know it as Russian penicillin.

Our God-given immune system is so incredibly vital to maintain during this uncertain time of the COVID-19 viral pandemic.  Garlic, onion, grapefruit, and ginger all have immune-boosting properties with most showing anti-viral benefits. Garlic and onions are functional foods from the allium family and the phytochemical compounds have several anti-viral functions especially against respiratory viral infections.1-3

In order to maximize the phytochemical potential it is best to chop the garlic before cooking it or eating it raw so the heat-sensitive enzyme alliianse can activate the phytochemical organosulfur compounds. Grapefruit is a low-sugar fruit rich in bioflavonoids and vitamin C-high in antioxidant activity. Liminoid phytochemicals in grapefruit promote the formation of glutathione-S-transferase, a detoxifying enzyme and powerful antioxidant.4-6

Ginger has been shown to have antiviral activity by inhibiting the viral activity and boosting antioxidant status by promoting glutathione S-transferase.7 Horseradish is a cruciferous vegetable which contain powerful detoxifying organosulfur compounds known as isothiocyanates  (ITCs). Studied for their ability to remove carcinogens and kill cancer cells, ITCs also exhibit anti-viral properties and stimulate the immune system to attack and kill viruses.8-10

Friends, isn’t it amazing that our Heavenly Father created our immune systems to be a highly coordinated and powerful defense team and the foods He created that help build up that system?

Remember to thank Him every day for the healing gifts He gives us!

“I will praise thee for I am fearfully and wonderfully made: marvelous are thy works; and that my soul knoweth right well.” - Psalm 139:14  

Recipe for Modern Manna’s Immune-Boosting Tea (Russian Penicillin)

1 part garlic cloves
1 part onion
1 part fresh grapefruit
1 part ginger



Chop all ingredients by hand or food processor if desired and add to 2 quarts of filtered water. Bring to a boil then simmer for 30 minutes. Strain the ingredients and drink 1 cup one to three times per day.  


Recipe for Modern Manna’s Super Tonic  

Click hereto buy a bottle => Super Tonic

1 part fresh-chopped onion
1 part fresh-chopped garlic cloves
1 part fresh ginger root
1 part fresh-chopped horseradish root
1 tsp cayenne powder or 8 dried cayenne peppers
Apple Cider Vinegar to cover top of herbal mixture



Place all chopped ingredients in a blender and add enough raw, unfiltered, unbleached, undistilled apple cider vinegar to cover the top of the herbs. Blend and pour into an airtight container then top off with more vinegar, filling to the top. You can also finely chop ingredients in a food processor or by hand if desired. Add a piece of parchment or wax paper to the top of the jar so the acid from the vinegar doesn’t break down the metal from the lid.

Make sure to shake the tonic at least once per day. Leave sealed in a dark cool place for at least 14 days, no need to refrigerate. Many recipes say you can leave it for one month. Once it is ready, filter the mixture using clean cheesecloth and enjoy the tonic as a salad dressing, cook with it, or use as a marinade for tofu or vegetables. You can also take 1-2 tablespoons (0.5-1 ounces) per day.


Contraindication Notes:

*Grapefruit can interfere with certain medications so always check with your healthcare provider. Use with caution if taking prescription medications like statin drugs, immunosuppressants, calcium-channel blockers, anti-histamines, hormones, and antiviral medications.

*Garlic has blood thinning properties so always speak to your health care provider (HCP) if you are taking any anticoagulant medications. Garlic may also interact with other heart or blood pressure medications check with your HCP before taking garlic regularly, in high doses, or as a supplement.  



Hydrotherapy is an ancient natural remedy utilizing contrasting water treatments for multiple conditions. Nurses and doctors once trained in hydrotherapy with many successful treatment outcomes. According to Drs. Agatha and Calvin Thrash, hydrotherapy stimulates blood circulation to the affected area increasing white blood cell activity to destroy pathogens.


During the height of the Spanish flu pandemic of 1918, ninety seminary students living in a boarding house in Hutchinson, MN came down with flu-like symptoms. Nurses and doctors tirelessly cared for the sick using hydrotherapy fomentation treatments to the neck, chest, and abdomen. Not one life was lost, all without the use of drugs!

There are also other successful reports passed down from previous generations on the effectiveness of hydrotherapy. 


Hydrotherapy Techniques 

"A tender treatment given with sympathy and tact will do more good than the most skilled treatment given in a cold, indifferent way." -The Ministry of Healing, p. 244


If the person is willing, offer to pray with them at the beginning and the end of each treatment session.


Warming Sock Neck Treatment 

Our family has used this remedy many times if we feel the first sign of a sore throat coming on- either a feeling of scratchiness or tickle in the back of the throat.

Ice water
Thin cotton sock
Thick large wool sock
Plastic wrap
Safety pin



Place thin sock in small bowl of ice water and wring out excess water. Another option is to place a small amount of ice chips inside the white cotton sock. Just make sure the ice stays in the sock and rests in front of the throat. Next wrap the thin sock with a thick dry wool sock and secure with a safety pin. Cover with plastic wrap to keep extra heat in and moisture. Keep the wrap in place around the neck and go straight to bed. This treatment can be repeated for the next two days. 


Essential Oil Steam Ventilation Tent 

Essential oils have numerous health benefits and many contain anti-viral properties.11 This treatment is best used for congestion. Not advisable for a fever as you always want to keep the head and forehead cool.

  • Large cooking pot filled one third of the way with water or 
  • Thick dishtowel or trivet
  • Large thick blanket that can drape from head to the floor- natural materials are more breathable, flannel or wool works well
  • Essential oil, few drops (options: eucalyptus globulus, oregano oil, Thieves®  essential oil by Young Living, R.C.™ essential oil by Young Living, On Gaurd® by dōTerra, or NOW® Nature’s shield essential oil)


Bring non-chlorinated filtered water to a gentle boil in a large cooking pot. You can also boil water in a kettle if desired. Once it boils, turn off the stove. Cover with a lid. Lay a dishtowel or trivet on the floor or place it on a low table. Using potholders take your pot and place it on the towel or trivet and carefully remove the lid. Allow the first wave of steam to escape and then place a few drops of desired essential oil in the steaming water.


Our family likes to use eucalyptus because it opens up the bronchioles, can reduce cough frequency and has antiviral activity.12 Sit in a chair with the pot on the floor between your legs or if it is on the table get comfortable so you can still rest a good distance above it. Cover yourself with a blanket to keep steam in and breath normally for about 10 minutes. Add more hot water to the pot if you would like to remain there longer. Having a friend help you with this treatment will make it go much smoother.


Note: Most drinking water has chlorination byproducts and varying levels of more toxic chemicals including pharmaceutical byproducts! Interestingly enough, we have a higher exposure to chlorination byproducts (trihalomethanes) via skin and inhalation to the lungs when we bathe or shower in chlorinated tap water or swim in chlorinated pools.13

Hot and Cold Contrast Shower  

This is a great natural remedy for stimulating circulation and boosting white blood cell count. You do not have to wait until getting sick to start this easy hydrotherapy treatment.


When taking a shower turn on the water as hot as you can safely tolerate and shower for about 3 minutes. Adjust the temperature so you turn the hot water temperature down and turn the cold-water temperature on and shower for 30 seconds. Repeat this two more times for a total of 3 sets and always end on cold and briskly dry off.

                    Thank you for sharing with us those natural remedies especially during this time. I was happy to watch the part on sweat bath where you were sitting on a chair and covered with a blanket. That therapy is widely used in Africa, and because of it, I survived malaria that had killed thousands of people in Africa. Again, thank you for all the knowledge you’ve share with us. Keep up good work.

                    Geoff called a few weeks before BellaVita and was at his wits end. At 64, he was suffering with Crohn's disease, abominable pain, rectal bleeding, pancreatitis, hernias, and gallbladder surgery. His diet and lifestyle were horrible and his stomach and intestines were screaming. I asked him why he was trying to kill himself.
