Have you ever heard of Master Tonic which is a natural way to build and support your immune system? Thanks to a friend who was visiting, I now know about it and have added it to my daily routine!

I hadn’t until a friend, Thera, was visiting one day. She and her two young children had come to glean grapes after grape harvest was over. But, before she went out to pick, we sat, enjoyed a cup of coffee and talked about life in general.

As our conversation moved from one topic to another, we began talking about ways to build our family’s immune systems and natural remedies.

As we talked, Thera began to tell me of a home remedy her grandmother kept on hand. It sounded easy enough so I wrote down the recipe.

Since it is cold and flu season and we all want to do what we can to protect ourselves and our families – I wanted to share this immune buiding recipe with you.

Thera’s grandmother kept the Master Tonic on hand and when her grandchildren visited with a cough or complained of a sore throat, she gave them a couple of tablespoons.

You may be skeptical but I have found old fashioned remedies to be very effective in healing common illnesses – see How to Get Rid of Gallstones, A Natural Remedy for Pink EyeGet Rid of Bladder Infections Naturally and Passing Kidney Stones Naturally.

I love budget friendly do-it-yourself remedies and for under fifteen dollars, I made a gallon and a quart of Master Tonic. When stored in a dark colored bottle, it will keep indefinitely – I thought it was easier to make a large batch at once!  😉

Before giving the benefits of each of the Master Tonic ingredients and the recipe, I thought it would be good to think about a few very simple things that we can (especially with children) that can also help protect ourselves from infections.

  1. Avoid Contact – First of all, especially during times that infection breakouts (like flu season) when possible, it is best to stay home. Is that possible for most of us? Normally not, but when it is, take advantage of a little solitude. Shopping trips and doctor visits can be planned as far as possible to be done during the slower hours for the business.
  2. Good Hand-Washing While this is easy to overlook, cleanliness is important – with colds, flue or other viruses. Because germs can be easily transported from our hands to our mouths, nasal passages and the delicate tissue of the eyes – wash your hands and encourage your children too. Be aware of what you touch and wash your hands!
  3. Take steps to build your immune system. A great start is to add Master Tonic to your daily regimen. Here are some other tips to help support your immune system.
  • Have a Diet Rich in Probiotics – Health begins from the inside out – your gut health is of utmost importance. Having mainly “good” or beneficial bacteria inhabiting your gut means your body can more effectively deal with intruding viruses and bacteria – it is not weakened by fighting the effects that “bad” or harmful bacteria within your own system can cause – autoimmune problems, inflammation, allergies… Your body’s immune system is stronger to fight an intruding virus or bacteria. Probiotic foods include yogurt, kefir, sauerkraut, fermented carrots, raw apple cider vinegar (which is in Master Tonic) and kombucha.
  • Real Food Diet – Give your body what it needs to maintain, build and repair with nutrient dense foods. Non-processed foods are the most nutrient dense focusing on superfoods that are packed with vitamins, minerals and antioxidants – dark leafy green vegetables, avocados, grass-fed meats, omega-3 rich fish, nuts, citrus fruits, whole grains, good fats like coconut oil and olive oil…
  • Fermented Cod Liver Oil – Fermented Cod Liver Oil is a traditional superfood that is rich in the fat soluble vitamins – vitamins A, D, and K. The fermented cod liver oil is easily digestible and the nutrients are readily available to your body. It helps boost your immune system! We use this Butter Oil/Fermented Cod Liver Oil  – our favorite flavor is the Chocolate Creme and we take 1/2 tsp to 1 tsp daily. There are also several choices of Fermented Cod Liver Oil here.
  • Avoid excessive intake of foods that suppress the immune system including refined sugar, alcohol and highly processed foods. Anything in excess can be harmful!
  • Get Adequate Rest – Your body needs rest and specifically sleep to rebuild and repair. The average person needs 7 – 8 hours of sleep per night. A six-year study involving 1.1 million people conducted by the University of California San Diego found that people who slept 6.5 to 7.4 hours a night had a lower death rate than those with shorter or longer average sleep times.
  • Reduce Stress – Prolonged stress puts a strain on your adrenal gland and this decreases your immune system’s ability to function and do its job, protect you! Take steps to decrease the stress in your life.
  • Exercise – Exercise is important for overall health – it gets your blood pumping, helps balance hormones and stimulates the body’s immune system.

Since each ingredient in the Master Tonic has valued medicinal properties, before I give the recipe, let’s take a look at them.

Immune Boosting Master Tonic

There is definitely a time and place for medical intervention but, prevention (building our immune system) is by far the least expensive and effective option.

With all the health benefits that the Master Tonic ingredients contain, I now start my day with a couple of tablespoons in a glass of water and it adds a nice zing!

Looking over the ingredients, you might wonder how it tastes. Actually, it is not bad but then again, I dilute it in a glass of water.

I think if taken straight, it would taste, well, a bit like medicine!
