When I lost my thyroid, I was scared of “what’s next?” My doctor had told me I’d die if I didn’t take radioactive iodine, and at the time, I didn’t know what to believe. I had been losing faith in a system that I had trusted. I had small children, and I didn’t know that the body was capable of regenerating and recovery from an autoimmune illness.

What I didn’t realize then was that my body was doing exactly what it was designed to do … protect me. It was overreacting, because it was inflamed and out of balance. Once I understood that, everything changed.

Later, when I started studying natural healing and herbology, I learned that the immune system can be re-trained. It can learn new responses. It can be calm again.

That lit a fire in me. If my immune system could be retrained, it meant I wasn’t doomed. It meant no one was doomed. The system I trusted didn’t know how to make us better!  It only knows how to manage.

Your Immune System Never Forgets, But It Can Re-Trained

Your immune system has a memory just like your brain does. It keeps track of every food, microbe, toxin, and emotion it comes across, so it knows how to respond the next time you are exposed. That’s why immunity to certain viruses can last decades. The body remembers.

Sometimes, that memory gets scrambled. Chronic stress, gut inflammation, nutrient deficiencies, and chemical exposures confuse the immune system. It gets a panicked signal and starts tagging harmless foods, or even your own tissues, as dangerous. That’s how autoimmunity happens.

The good news is that this isn’t a one-way street. Immune memory is flexible. We can remap old patterns of overreaction and learn a new way to get back into balance once you “do the things”…lower inflammation, rebuild the gut, and restore communication. These can be done through food, herbs, and mindset.

 That’s my passion project and what I’ve devoted my life to do. I help people re-train their immune system with new information, so it can go back to protecting rather than attack-mode.

The Goal Isn’t to “Boost” Immunity But to Balance It

We’re constantly told to “boost” the immune system. Take this supplement. Drink that tonic. But if you already have an overactive immune system, the last thing you need is more stimulation. 

What we need is regulation. Balance. The ability to tell the difference between what belongs to you and what doesn’t. That’s called immune tolerance, and it’s one of the most important concepts.

When tolerance breaks down, the immune system goes rogue. You get food sensitivities, seasonal allergies, flare-ups, fatigue, and inflammation that just can’t find relief. When tolerance is restored, your immune system becomes calm, clear, and focused again.

So how do we restore it? Through the very things nature designed to create balance, through our food, minerals, plants, and a relaxed, calmer mind.

Food and Herbs: The Teachers of Immune Memory

Food provides information. Every bite you take sends a message to your cells about what’s safe, what’s providing nutrition, and what’s threatening. Over time, those messages shape your immune system’s memory.

That’s why herbs and whole foods are so powerful. I’m talking about real food, whole foods. They’re full of the signals your body evolved to recognize.

Let’s look at how this works and notice you probably already have these in your kitchen.

•  Turmeric and ginger contain compounds that calm NF-κB, your body’s main “inflammation switch.” They tell the immune system, “It’s okay, you can relax now.”
• Rosemary and oregano contain rosmarinic acid and carvacrol which help overactive immune cells calm down and communicate properly.
• Garlic and onions are rich in sulfur compounds that turn on your body’s detox enzymes and help it clean up damaged proteins and inflammatory waste.
• Parsley, basil, and cilantro contain flavonoids that reduce histamine reactions and support the gut lining. This is where 70% of your immune system lives.

Herbs are also rich in trace minerals that keep your immune system’s electrical signals strong. Zinc, magnesium, selenium, and iron are necessary for immune balance. When you cook with herbs grown in rich soil, you’re refilling those reserves naturally without a single pill.

Herbs don’t force the body to act the way pharmaceuticals do; they remind it how.

Inside the Gut–Immune Classroom

 If your immune system is the student, your gut is the classroom. Everything it learns happens there. 

The gut is needed for digestion, but it is also home to trillions of microbes that help regulate inflammation, make vitamins, and produce short-chain fatty acids like butyrate. Short chain fatty acids literally teach immune cells to tolerate rather than attack.

 When your gut is healthy and diverse, the immune system gets a clear message: “You’re safe.”

When the gut is inflamed or leaky, that message gets distorted. Your immune system knows something is wrong, so it starts firing at anything that moves.

Herbs, fiber-rich foods, and polyphenols (found in brightly colored foods) act like tutors in that classroom. They feed beneficial bacteria and help rebuild the gut wall, so your immune system can finally calm down and remember who it’s supposed to be protecting (that would be YOU).

Belief Is Biology

Not everyone who eats the right foods heals.

 I’ve seen it over and over. They have the recipes, the meal plans, and the herbs, but something inside still says, “I’ll never get better.”

 That belief alone keeps the body locked in defense mode.

 Your nervous system and your immune system are in constant communication. When you live in fear or hopelessness, your immune system stays on alert. When you start believing in your body again, truly believing, it begins to relax, repair, and regenerate.

 That’s why mindset isn’t fluff. It’s a part of physiology. Calm, gratitude, and safety activate your vagus nerve, lower cortisol, and allow your immune system to shift from attack to healing.

A Bowl That Teaches Calm

Food is Medicine!  And I love to use food functional to help the healing process.

Rosemary Lentil Soup with Lemon and Greens

Serves: 4  Prep Time: 10 minutes  Cook Time: 30 minutes

Ingredients

• 1 tablespoon water or vegetable broth, for sautéing
• 1 medium onion, chopped
• 3 cloves garlic, minced
• 1 medium carrot, diced
• 1 cup brown or green lentils, rinsed
• 1 teaspoon ground turmeric
• 1 tablespoon fresh rosemary, chopped (or 1 teaspoon dried)
• 6 cups vegetable broth
• 2 cups chopped kale or spinach
• Juice of 1 lemon
• Sea salt and black pepper, to taste

Instructions

1. In a large soup pot, heat a tablespoon of broth or water over medium heat. Add the onion, garlic, and carrot, and sauté for 5–7 minutes, until softened and fragrant.
2. Stir in the lentils, turmeric, rosemary, and remaining broth. Bring to a boil, then reduce the heat and simmer uncovered for about 30 minutes, or until the lentils are tender.
3. Add the greens and cook for 2–3 minutes, just until wilted.
4. Remove from heat and stir in the lemon juice. Season with sea salt and pepper to taste.
5. Serve warm, garnished with a sprig of rosemary or a wedge of lemon if desired.

Tip: This soup freezes well and tastes even better the next day.

This is true Functional Food! Every ingredient has a purpose:

• The lentils feed your microbiome.
• The rosemary teaches inflammation to calm down.
• The turmeric supports your liver’s detox pathways.
• The greens restore minerals that your immune cells depend on.

This creates a conversation with your cells. These foods send a reminder to your cells letting them know that they’re safe, supported, and capable of healing.

Healing Isn’t Always Fast, But It Can Happen

Retraining the immune system takes time. You can’t rush biology.

Your cells need repetition, just like we do. They need to hear the same calm messages over and over , through food, herbs, movement, and mindset , until it finally clicks: we’re safe now.

And when it clicks, everything shifts.

You sleep better. Your energy is stable. The flare-ups quiet down. Your labs start to improve.

 That’s your immune system remembering peace.

What “Saving Body Parts” Really Means

When I say I’m on a mission to save body parts, I mean it literally. I lost one, because I didn’t know any better, and I don’t want anyone else to go through that.

I’ve seen people, including myself, lower antibodies, reverse inflammation, and get off medications they were told they’d need for life.

Your body isn’t your enemy. It’s your ally. It’s been defending you all along, maybe a little too fiercely, but always with good intentions. 

When you give it the right inputs, it remembers how to protect without overreacting. It remembers balance. It remembers you.

You Can Rewrite the Story

Your immune system has a memory. That means it can remember trauma, but it can also remember healing.

Every time you choose real food over processed, calm over chaos, herbs over chemicals, you’re creating new memories. You’re showing it that healing is safe again.

That’s what this work is really about: teaching your immune system, and yourself, that you’re learning, healing, and doing something good for you every day.
