Herbs and Natural Remedies to Support a Strong Immune System

By Rashelle Black, NP

Let’s be honest.

Most of us don’t think much about our immune system until we’re standing in the supplement aisle with a sore throat, Googling “How do I stop getting sick?” while clutching a box of tissues.

I’ve been studying natural health, nutrition, and herbal medicine for decades, and one thing I’ve learned is this:

A healthy immune system isn’t built overnight.

It’s built through the small things you do consistently—how you eat, how you sleep, how you manage stress, and whether you’re giving your body the nutrients it needs to do its job.

The good news? Your body is incredibly intelligent.

Every second of every day, it’s working behind the scenes to identify threats, repair damage, and keep you healthy. When you support those natural processes, you’re giving your immune system the tools it needs to do what it was designed to do.

Your Immune System Is Working Harder Than You Think

Think of your immune system as your body’s personal security team.

Your skin serves as the outer fence. Your tears, saliva, and mucus help trap unwanted invaders before they gain access. If something slips past those defenses, your stomach acid, gut microbiome, lymphatic system, liver, spleen, and specialized immune cells jump into action.

One area that deserves special attention is the gut.

Approximately 70% of your immune system resides in and around the digestive tract. That’s one reason why digestive health and immune health are so closely connected. When your gut is thriving, your immune system tends to perform better too.

Which brings us to one of my favorite places to start.

Feed Your Gut Like Your Health Depends on It

Because it does.

Fermented and cultured foods help support beneficial bacteria that play an important role in immune function.

Some of my favorites include:

• Sauerkraut
• Kefir
• Kombucha
• Miso
• Yogurt with live cultures

You don’t need to eat massive amounts. Even small servings on a regular basis can help support a healthy microbial balance.

Manuka Honey: Nature’s Sweet Overachiever

Not all honey is created equal.

Manuka honey, sourced from New Zealand and Australia, contains naturally occurring compounds that have made it a favorite in traditional wellness practices for generations.

I like keeping a jar on hand during the colder months. A teaspoon slowly enjoyed straight from the spoon—or stirred into warm tea—can be a comforting addition to your wellness routine.

Look for products carrying UMF or MGO certification to ensure authenticity.

The Humble Bowl of Bone Broth

Your grandmother may have been onto something.

A well-made bone broth provides amino acids and nutrients that support overall wellness while delivering the kind of comfort food your body appreciates when it’s under stress.

For extra immune-supporting goodness, try simmering your broth with:

• Garlic
• Ginger
• Turmeric
• Thyme
• Onion

The result is simple, nourishing, and surprisingly powerful.

Immune-Enhancing Herbs and Spices

Adaptogenic Mushrooms: The Unsung Heroes

If mushrooms aren’t currently part of your wellness routine, they may deserve a second look.

Varieties such as:

• Reishi
• Turkey Tail
• Maitake
• Shiitake
• Cordyceps
• Chaga
• Lion’s Mane

have been studied for their ability to support healthy immune function and overall resilience.

Think of them as nutritional reinforcements for your body’s natural defense systems.

Green Tea: A Daily Wellness Habit Worth Keeping

Green tea contains powerful antioxidants, including EGCG (epigallocatechin gallate), which help protect cells from oxidative stress.

It’s one of the simplest additions you can make to a healthy lifestyle—and it pairs nicely with a few quiet moments away from your phone.

Powerful Immune-Supporting Herbs

Essential Immune-Supporting Supplements

• Zinc: Plays a critical role in normal immune function and is one of the most researched nutrients for seasonal wellness support.
  • 50-100mg daily in divided doses reduces cold and flu duration.

• NAC (N-Acetyl Cysteine):helps support the body’s production of glutathione, one of its most important antioxidants.
  • 600mg 2-3 times daily (adults only) shortens illness by 2-3 days; increase hydration.

As always, speak with your healthcare provider before beginning any new supplement regimen.

Don’t Forget the Basics | Lifestyle Tips to Support Immune Health

• Hydration: Drink plenty of water to reduce stress on your body during illness.

• Rest: Sleep is critical for immune function and recovery.

• Light Movement: Gentle walks improve circulation and oxygen delivery.

• Bathing: Warm baths increase circulation and help detoxify through mild sweating, supporting immune organ function.

Final Thoughts

People often ask me what the “best” herb is for the immune system.

The truth is, there isn’t one.

A resilient immune system is built through consistent daily habits, nutrient-rich foods, restorative sleep, movement, hydration, and strategic herbal support when appropriate.

The goal isn’t perfection.

The goal is giving your body the resources it needs to do what it was beautifully designed to do.

Your immune system is already working hard for you.

A little support can go a long way.
