Building and Protecting the Immune System with Herbs

Building and Protecting the Immune System with Herbs

Incorporating immunomodulant, immune stimulant, and antiviral herbs can help to build, protect, and support your immune system in the long-run.

Immune Stimulants

Those who travel frequently, have become exposed to illnesses like COVID19, and are prone to getting sick, these herbs may be right for you. For individuals who have a lot of stress, increasing demands, or overwhelmed with simply tasks daily tasks, immunity herbs may play an important protective role

These herbs can be used on a short-term basis to address acute infections while stimulating white blood cell activity. They can help to fight off infection during the initial stages of and throughout the duration of an illness. To be affective, they need to be administered frequently. 

Used over a long period of time these herbs can result in imbalance, and should be used for short periods of time. 

  • Echinacea (Root, seed, aboveground parts): This immune booster walks the line between 'immunomodulant' and 'immune stimulant.' 

  • Garlic: Bulb

  • Japanese Honeysuckle: Flowers and flower buds

  • Usnea: Lichen



These herbs are traditional tonics used to support the immune system. They are slower-acting with more prolonged effects when compared to immunostimulants. Their effect is more balancing than stimulating for the body. Used to address low immune resilience, immune systems that are overactive (allergies, autoimmunity), and harmonize endocrine and nervous systems, which regulate immunity. Many immunomodulators are also adaptogens. Used daily, these herbs bolster immunity and lessen the chance of succumbing to common viral infections. 

Keep in mind, immunomodulant and tonic herbs are valued for gentle, general, and slow long-term benefits, and are not considered an emergency response or any kind of cure. These herbs aid in increasing immune responses.

  • Ashwagandha: Root

  • Astragalus (Root): Improve immune activity by increasing white blood cells, stimulating adrenal-cortisol activity, and encouraging red blood cell formation in the bone marrow.

  • Eleuthero: Root

  • Ginseng: Root

  • Holy Basil: Above-ground parts

  • Reishi: Mushroom fruiting body

  • Rhodiola: Root

Herbal Immune Tonics

These herbs are used as long-term immune tonics for cases of poor immunity. Immune tonics differ from Immunomodulators. They don't have the same scientific stamp of approval, but have the same degree of regulating effects on the immune system.

  • Calendula: Flower

  • Chaga: Mushroom fruiting body

  • Elder: Flower and fruit

  • Lion's Mane: Mushroom fruiting body

  • Maitake: Mushroom fruiting body

  • Turkey tail: Mushroom fruiting body



Antimicrobial herbs have compounds that deter pathogenic bacteria, fungi, viruses, and protozoans. They are helpful in aiding to trim an infection. It is helpful to know what kind of infection you are working with and the direct microbial qualities of any herbs you are considering for treating that infection.

  • Bee Balm: Aboveground parts

  • Black Pepper: Seeds

  • Cayenne Peppers: Fruit, seeds

  • Cinnamon: Inner Bark

  • Clove: Buds

  • Elder (Flower and fruit): A gentle anti-viral herb and folk remedy for the flu. 

  • Garden Sage: Aboveground parts

Non Herbal Activities That Affect Immunity

Our moods - and sense of connection - have a profound effect on our white blood cells (immune cells, B cells, T cells, NK cells, macrophages). Stress and social isolation are immune "downers." Loneliness is associated with increased cortisol levels and lowered immune profiles. Adrenaline and cortisol weaken immune function. That is why if you've been feeling stressed or down, you may begin to feel under the weather. Conversely, when we are happy, our cells signal the production of serotonin, dopamine, and relaxin, which have a strengthening effect on the immune system. That is why taking care of yourself, ensuring you are doing the best for your body, and feeling happy is important. If we consistently ignore the basics of good sleep, nutrition, water, and lifestyle, we have feel adverse effects.
