21 Herbs to Increase Immunity: The Herbalist’s Go-To Guide

You don’t have to be an herbalist to learn how to master your immune system.
And it definitely helps to know which herbs to reach for and how they work together. These 21 botanicals have stood the test of time, backed by both tradition and modern herbalism alike. We’ve sorted them into four practical categories that reflect how herbalists actually support immune health. From stress support to full system recovery, these herbs have your back, your sinuses... and your peace of mind!

Here are four herb groups to help you remember what to take — and when to take it:

Primary Activators: These herbs help wake up your body's natural defenders and get your set your immune system into action.

Respiratory Champions: They support the lungs, sinuses, and upper respiratory pathways.

Lymphatic Allies: These keep your internal cleanup crew moving, helping your body drain, detox, and defend.

Specialty Warriors: For when you need backup, fast. These herbs offer targeted support during seasonal shifts and immune flare-ups.

Here is the heart of it. Herbs work with your body’s natural immune responses. Across cultures and generations, people turned to astragalus, echinacea, elderflower, and other botanicals long before immune wellness was a trend. These plants provide gentle support for immune balance, promote a healthy inflammatory response, and foster overall wellness during seasonal transitions. Herbalism does not override your immune system. It supports the body systems you already have.

A strong immune system takes more than herbs once cold season hits. Think about the whole picture. Nourishing foods rich in vitamin C, steady vitamin D levels, restorative sleep, hydration, manageable stress, and lifestyle choices all work together. Herbs are simply one of the most dependable tools in the toolkit to support immunity. Whether you are supporting everyday immune health, caring for your family, or looking for gentle plant allies that fit your natural wellness routine, these 21 herbs offer a foundation you can feel confident about.

How Herbalists Think About Immune Support

The strongest herb for the immune system? There really is no single winner. Your immune system is a full-body network that includes white blood cells, protective barriers, healthy inflammatory responses, and communication between multiple organs. It is always adjusting, always responding, and always working in the background. Because of this complexity, herbalists look at immune support through a holistic lens, focusing on how plants help maintain balance within different parts of this system.

Some herbs are used for short-term support when you want to stay on top of seasonal challenges. Others are traditionally leaned on for ongoing nourishment that helps maintain healthy immune function over time. Certain botanicals are known for supporting the respiratory system, while others help keep the lymphatic system moving so your body can maintain healthy circulation and normal immune pathways.

This is why we group immune-supportive herbs into categories. Each reflects how herbalists historically match plants to different wellness needs, whether you are looking for everyday support, respiratory comfort, lymphatic flow, or more specific seasonal help.

Here is the simple approach to increasing immunity naturally. Match the herbal category to what your body needs in the moment. Feeling worn down? Explore Primary Activators. Looking for upper respiratory comfort? Reach for Respiratory Champions. Want to encourage healthy flow and movement? Lymphatic Allies may be your go-to. Need focused support during seasonal transitions? Specialty Warriors can help round out your routine.

Let’s take a closer look at each category.

Primary Immunity Activators

These are your frontline defenders: the herbs that wake up your immune cells fast. They support white blood cells, supporting activity and giving your immune system the immediate backup it craves when facing seasonal challenges.

Think of these Activators as your immune system's personal trainers. They don't do the work for you, and instead, they strengthen your defenses and help your body respond quickly to threats.

What makes these herbs special is how they work with your body’s natural defenses. These herbs have been traditionally used to support healthy immune function, encourage normal immune cell activity, and help your body stay responsive during everyday seasonal challenges. Herbalists often reach for them when someone wants short-term support, feels run down, or is moving through periods of increased stress. They are not meant to diagnose or treat illness. They simply help your body maintain the strong, balanced immune foundation it is already designed to have.

Many people use Primary Immunity Activators cyclically (1-3 weeks on, at least one week off, depending on the herb) to maintain immune health without overstimulating the immune system. Others save them for acute situations when the immune system needs immediate reinforcement. Both approaches work, and it just depends on whether you're building daily immune defenses or fighting something actively.

Primary Immunity Activators:

• Elderberry - Elderberry supplements may be the most popular out of the bunch. This immunity superfood bursts with vitamin C, vitamin D, and free radical scavenging properties that support immune function while fighting oxidative stress, making it ideal for daily immune support and combating seasonal bugs.
• Astragalus - Used for over 2,000 years in traditional Chinese medicine as a "Qi tonic," this adaptogenic root stimulates immune cells through polysaccharides and is perfect for long-term immune building without overstimulation.
• Echinacea - Nature's Swiss Army knife enhances immune function by supporting the production of immune cells, with E. angustifolia used in stronger formulas like Kick-Ass Immune Activator and E. purpurea preferred for daily support in Daily Immune Builder.
• Baptisia - This resilient herb fortifies immune defenses with exceptional immune-boosting properties, working in harmony with your body's natural defenses to fast-track recovery, particularly supporting healthy immune responses to common bugs and germs.
• Usnea - Known as "Old Man's Beard," this powerhouse lichen provides microbial balancing effects and inflammatory-soothing properties, protecting your body from bugs while supporting respiratory immune function.

Respiratory Immunity Champions

Your respiratory system is one of the immune system's most critical frontlines. Every breath brings potential invaders, bacteria, environmental pollutants, and allergens directly into your body. Your lungs, sinuses, and throat contain specialized immune cells and mucous membranes forming a defense network against respiratory threats.

When these defenses get overwhelmed, you know it: congestion, coughing, difficulty breathing, that general respiratory distress feeling. That's when respiratory herbs step up.

These herbs have a specific affinity for lung tissue and your entire respiratory tract. They work multiple ways: some thin mucus so your body can expel unwanted invaders more easily, others soothe inflamed respiratory tissues with inflammatory-soothing effects, and many contain aromatic compounds that directly support healthy respiratory function.

Traditional medicine systems worldwide have relied on respiratory specialists for centuries. Native Americans used osha root for altitude sickness and to support the lungs. Traditional Chinese medicine incorporated mullein and elecampane for congestion.

Respiratory herbs contain naturally occurring plant compounds that help maintain healthy lung function, support normal mucus clearance, and protect against oxidative stress for delicate respiratory tissues.

People often reach for these herbs during seasonal shifts, times of environmental stress, or whenever they want to nurture long-term respiratory wellness. They offer focused, gentle support for the areas of the body that help you breathe easily and stay resilient.

Respiratory Immunity Champions:

• Osha Root - This Rocky Mountain native provides powerful respiratory support with microbial balancing properties and potent compounds, traditionally used to combat germs and support lung function, though conservation concerns make sustainable sourcing essential.
• Elecampane - A respiratory hero that soothes irritated bronchioles while supporting your body's ability to fight seasonal illness, with expectorant properties that help clear congestion from the lungs and support healthy immune responses in respiratory tissue.
• Mullein - This gentle respiratory ally helps soothe occasional dryness or irritation in the airways and supports healthy immune function. It is traditionally used during seasonal transitions to nurture comfortable breathing and overall respiratory wellness.
• Wild Cherry Bark -A traditional herb known for easing occasional throat and airway irritation, helping to calm the urge to cough, and supporting comfortable breathing. It is often used to nurture respiratory tissues and maintain overall respiratory wellness while your immune system does its natural work.
• Pleurisy Root - Named for its long history of use during times of respiratory need, this native herb supports healthy inflammatory responses in the lungs and helps maintain overall respiratory immune function. Herbalists often turn to it for gentle, targeted support when the breath and chest could use a little extra care.
• Yerba Santa - This aromatic California native opens airways while providing free radical scavenging properties and immune support for the entire respiratory tract, particularly valuable for addressing thick, stubborn respiratory congestion.

Lymphatic Supporting Allies

Here is something most people never learn about immune health. Your lymphatic system is one of the most important pathways for immune cells, yet it does not have a built-in pump like your cardiovascular system. Instead, it relies on movement, hydration, deep breathing, and supportive herbs to keep everything flowing. When the lymphatic system moves well, it helps maintain healthy immune responses and overall immune function.

When lymph becomes sluggish, your body may have a harder time circulating immune cells efficiently. Supporting healthy lymph flow is one of the simplest ways to boost your immune system naturally and maintain a strong, healthy immune system.

Some of these herbs are traditionally known as lymphatic movers that help encourage the natural circulation of lymph fluid throughout the body. Others fall into the category of alterative herbs, a term from traditional herbal medicine for botanicals that support the body’s natural detoxification processes and healthy tissue function. Many also provide gentle nutritive support, offering plant compounds, minerals, and vitamins that help nourish human immunity and overall health.

These herbs are subtle, steady, and foundational. Their immune-supporting properties are well regarded in herbalism because they help maintain balance, encourage healthy inflammatory responses, and support long-term immune health in a holistic way. Although they may not show up in conversations about quick immune boosts, they play a powerful role in complementary and integrative health practices.

When someone experiences occasional sluggishness, low energy, or feels like their system needs a reset, herbalists often consider whether the lymphatic system could use support. These herbs help maintain natural detoxification pathways, support the movement of immune cells, and nourish the tissues involved in immune defense. They are valuable for people wanting sustained immune support, especially during seasonal changes, periods of stress, or moments when the body needs extra nourishment for overall health.

Lymphatic Supporting Allies fit into any wellness routine that prioritizes a diverse diet, nutritious foods, vitamin C and vitamin D-rich choices, herbal tea rituals, and healthy living habits. These plants remind us that everyday wellness is built on steady, supportive actions that help enhance immunity naturally and sustainably.

Lymphatic & Supporting Allies:

• Red Root - An honored lymphatic herb traditionally used to support healthy lymph flow and natural circulation. It helps maintain normal movement of lymphatic fluids, which supports the transport of immune cells throughout the body. 
• Ginger Root - This warming herb is traditionally used to support healthy circulation and natural lymphatic flow. Ginger’s plant compounds offer gentle immune support and help the body maintain a balanced inflammatory response. It is also known for supporting comfortable digestion, which can help your body absorb the nutrients needed for overall health and immune function.
• Red Clover -A gentle alterative traditionally valued for its nutritive properties, it offers naturally occurring vitamins, minerals, and plant compounds that help nourish the body and support healthy immune function. Herbalists often lean on it to encourage normal lymphatic flow and to provide foundational wellness support, especially for women’s health and long-term immune system balance.
• Cleavers - Nature's lymphatic tonic provides gentle yet effective lymphatic movement support, helping your immune system clear cellular waste while supporting kidney function and overall detoxification to enhance immunity.
• Burdock Root -This resilient and traditional alterative supports the body’s natural cleansing pathways and helps maintain healthy liver function. It also offers prebiotic fiber that supports gut wellness, which plays an important role in overall immune health. By nourishing digestion, encouraging healthy elimination, and supporting balanced immune responses, burdock provides steady, foundational wellness support that pairs well with lymphatic herbs.
• Calendula - Often called the Doctor of the Garden in traditional herbalism, it's cherished for its gentle support of healthy lymphatic and circulatory flow. Its naturally occurring flavonoids offer antioxidant properties that help the body maintain a balanced inflammatory response. Herbalists value calendula for promoting overall tissue wellness and supporting healthy immune function across multiple body systems.

Specialty Immune Warriors

Which plant is best for boosting immunity? The honest herbalist answers that it depends on what type of support your body needs. That is where the Warriors come in. These botanicals are traditionally used for more specific wellness needs and offer targeted support when you want help maintaining healthy immune function beyond everyday routines.

Unlike daily immune builders or foundational herbs to increase immunity, these plants shine when someone is focusing on particular aspects of immune wellness. They are often used when the body is navigating microbial challenges, working to maintain a healthy microbial balance, or needing extra support for clear and comfortable respiratory pathways. Their beneficial effects come from unique plant compounds that are not as common in everyday culinary herbs.

Many of these botanicals have deep roots in traditional medicine systems, including Indigenous herbalism and Traditional Chinese Medicine, where they were used to support immune defense, healthy inflammatory responses, and overall vitality. Modern herbalists value them for their distinctive profiles, antioxidant properties, and the way they help the body maintain strong and balanced immune responses.

From an herbalist’s perspective, this group of herbs represents the art and science of herbal medicine. Each plant offers different therapeutic properties, active compounds, and energetic qualities that provide in-the-moment relief. Understanding when to reach for lomatium, how yerba mansa supports microbial balance, or why myrrh’s resin behaves differently from herbs rich in flavonoids or essential oils is what elevates immune support from basic to nuanced.

Potent herbs such as these remind me that immune health is truly complex and multifaceted. The more we understand human immunity, from our cells to the lymphatic system and digestive tract, the easier it becomes to choose herbs that support immune function holistically and effectively.

Specialty Immune Warriors:

• Lomatium - This powerful root is traditionally used to support healthy respiratory function and help the body maintain balanced inflammatory and immune responses. Its distinctive aromatic compounds offer focused wellness support for the lungs and upper respiratory system, making it a favorite among herbalists during seasonal challenges when the body benefits from extra immune nourishment.
• Yerba Mansa - Yerba mansa is one of herbalism’s most treasured traditional botanicals, valued for its warm, drying qualities and its ability to support healthy respiratory function. It helps the body maintain natural microbial balance and encourages clear, comfortable breathing during seasonal shifts.
• Myrrh - An ancient resin long valued in traditional herbal medicine for supporting natural microbial balance and overall immune wellness. Its rich aromatic compounds offer antioxidant properties that help the body maintain a healthy inflammatory response.
• Horseradish - Rich in vitamin C, vitamin A, and minerals, this pungent root provides respiratory support and improved circulation, particularly valuable during allergy season for upper respiratory immune function and quick sinus relief.

How to Use Immunity Herbs for Maximum Effectiveness

The strongest natural immune booster isn't a single herb. Instead, it is understanding how to use these 21 botanicals strategically. Professional herbalists think in layers: daily prevention, acute response, recovery support, and long-term building. Each layer needs different herbs and approaches.

Daily Prevention & Building

For everyday immune support, focus on gentle, long-term builders like elderberry and astragulus.

Daily Immune Support Options:

• Daily Immune Builder - Combines elderberry and astragalus, two herbs you can use consistently without overstimulation for adult immune support.
• Daily Immune Builder for Kids - Age-appropriate dosing with immune-boosting properties, gentle enough for developing immune systems.
• Elderberry Syrup for Kids - Kid-friendly immune support that tastes great and provides daily immune building.
• Immune Boost for Pregnancy - Ensures you can support immune function safely during this critical time for women's health.

Acute Immune Activation

When you feel something coming on, that first tickle, unusual fatigue, or exposure to someone sick, shift immediately to acute activation. This is when you want stronger immune-stimulating properties from echinacea and baptisia.

Acute Immune Support Options:

• Kick-Ass Immune Activator - Potent immune enhancement for adults when you need immediate immune response.
• Kick-It Immune for Kids - Similar immune-boosting properties in child-safe dosing for when kids need extra support.

Usage: Take these at the first sign of immune challenge, every 2-3 hours during the first day, then 3-4 times daily until symptoms resolve. The goal? Rapid immune response to combat bugs before they take over.

Recovery & Stubborn Symptoms

For stubborn respiratory symptoms or post-illness recovery, layer your support with specialty herbs targeting specific challenges.

Recovery & Targeted Support Options:

• Kick-Ass Biotic - Targets microbial imbalances specifically with multiple immune-enhancing properties.
• Get Over It! - Supports that final push when you're recovering from a bug but still feel depleted, or you have stubborn and lingering mucus.
• Serious Cough – Provides focused herbal support for throat and respiratory comfort, helping you maintain clear, easy breathing while soothing the urge to cough.
  

Respiratory-Specific Support:

• Deep Lung - Combines Respiratory Champions with Activators for comprehensive respiratory support.
• Kick Ass Sinus - For fast-acting sinus support, this formula soothes irritation and helps to clear your sinus pathways.
• Congestion Rescue for Pregnancy - Gentle respiratory and immune support during pregnancy.
• Congestion Rescue for Kids - Child-appropriate respiratory and immune support when kids need extra help.

Lymphatic Support

When your immune system feels sluggish or you're recovering from illness, lymphatic flow becomes critical.

Lymphatic Support:

• Lymph Mover - Supports the healthy flow of your lymphatic system, which acts as a key pathway for immune cells. This gentle support helps your immune system stay responsive and balanced, so you can maintain strong, steady immune wellness.

Many herbalists alternate between immune-focused herbs and lymphatic support because both play important roles in maintaining immune balance. During times when the body is regaining its strength or when someone wants extra support for overall wellness, this combination helps keep the immune system responsive, steady, and well-nourished.

Building Your Daily Immune Routine: Beyond Herbs

Herbal medicine is powerful, but it works best when supported by other immune-building practices. Think of herbs as one piece of a larger wellness puzzle.

Diet & Nutrition

Your healthy diet provides the raw materials your immune system needs. Prioritize nutritious foods rich in vitamin C (ascorbic acid), citrus, berries, leafy greens, vitamin D (fatty fish, egg yolks), and other specific vitamins essential for immune cells. Remember: about 70% of immune cells live in your digestive tract. The foods you eat directly influence immune function through this gut-immune connection.

Consider fermented foods for probiotic support, adequate protein for T-cell and white blood cell production, and colorful vegetables for protection against environmental pollutants and oxidative stress.

Sleep & Stress

Quality sleep plays a major role in how your immune system stays balanced. During deep, restorative sleep, the body produces important immune signaling molecules and supports healthy white blood cells in the bone marrow. When sleep is consistently short or disrupted, the body may have a harder time maintaining steady immune function and overall resilience.

Stress is another key factor that often gets overlooked. Daily pressures can elevate cortisol, which may impact how the body maintains healthy immune responses and balanced T cell activity. This is one reason herbal traditions, including Traditional Chinese Medicine, rely on adaptogenic herbs like ashwagandha, holy basil, and eleuthero. These herbs help the body adapt to stress and support a sense of calm, which indirectly supports the conditions needed for a healthy immune system.

Pro Tip: Supporting restful sleep and healthy stress levels is one of the most effective ways to create a strong foundation for immune wellness. WishGarden’s Sleepy Nights offers gentle support for deep, natural rest, while Deep Stress helps the body maintain balance during demanding times. Together, they help create the internal environment your immune system needs to thrive.

Movement & Professional Guidance

Regular movement supports immune function by improving lymphatic circulation (remember, no pump!) and calming inflammation, and supporting overall health. Even 20-30 minutes of moderate daily activity can significantly boost your immune system. I believe that something as simple as walking every day can change your health and your life. 

It's important to note, if you experience autoimmune disorders or have a specific health condition, consult a healthcare professional before starting new workout rouintes or introducing new supplements into your body. While herbs provide immune-boosting properties with minimal adverse effects, they're still powerful medicine deserving respect and proper guidance.

FAQ: Herbs to Increase Immunity and Everyday Immune Support

What are the best herbs to naturally boost immunity?

Herbs like echinacea, elderberry, astragalus, ginger, and osha are among the most commonly used botanicals for supporting immune function. These herbs contain plant compounds and antioxidant properties that help maintain a healthy immune system, encourage balanced immune responses, and nourish overall wellness. The “best” herb depends on what part of immune health you want to support.

How do herbs support immune function?

Many herbs offer immune-supporting properties through naturally occurring vitamins, minerals, flavonoids, polysaccharides, and other active plant compounds. These ingredients help maintain healthy inflammatory responses, support white blood cells and T cells, and promote general immune resilience. Herbal medicine takes a complementary and integrative health approach, focusing on overall immune balance rather than targeting a specific condition.

Can herbs boost your immune system during the cold season?

Herbs can be one part of a holistic routine that supports immune defense during seasonal transitions. Elderberry, echinacea, astragalus, and ginger are popular choices thanks to their immune-enhancing properties. Combining herbs with a healthy diet full of nutritious foods, vitamin C, and vitamin D, consistent sleep, stress management, and movement creates a strong foundation for immune wellness throughout the season.

Do immunity herbs help with stress or fatigue?

Stress has a major impact on immune health because elevated cortisol can influence immune responses. Adaptogenic herbs such as ashwagandha, holy basil, and eleuthero are traditionally used to support the stress response, which indirectly supports immune wellness. Many people pair immune herbs with herbs for sleep and relaxation to maintain better overall balance.

Is it safe to take immune-boosting herbs every day?

Some herbs, such as elderberry, astragalus, and ginger, are traditionally used daily for long-term immune support. Others, like echinacea and baptisia, are often used for the short term. Your ideal routine depends on your goals and your body’s needs. It's always good to give your body a break after consistent and long-term use (3 weeks to 6 months, depending on the herb). If you have autoimmune disorders, chronic diseases, or take medications, it is best to consult a healthcare professional before starting new herbal preparations.

What is the best immune-boosting tea?

Popular immune-boosting tea combinations often include elderberry, ginger, echinacea, and lemon. These herbs provide antioxidant properties, immune-supporting benefits, and comforting warmth. You can brew them together or pair them with additional herbs based on your wellness needs.

How do diet and lifestyle affect immune function?

A healthy immune system depends on many factors beyond herbs. A diverse diet rich in vitamin C, vitamin D, folic acid, and other essential nutrients supports immune cells. Regular movement, quality sleep, hydration, and stress management are equally important. Herbs simply complement these immune health foundations.
