Building Your Immune Foundation for Cold and Flu Season
Lately, a few patients have been asking our Medical Herbalist, Julia Richards, for an immune tonic to prepare for the colder months.
There are many herbs that support immune health and they work in different ways. In herbal medicine they are often grouped as:
Immunostimulants — give the immune system a short, sharp boost when you’re fighting something off. Echinacea is a well known example.
Immunomodulators — help to balance and regulate immunity over time. Reishi mushrooms are effective.
Adaptogens — support the body’s stress response, improving resilience. Ashwagandha is a popular one.
In addition:
Anti inflammatories — calm excessive inflammation, reducing immune over reactivity. Turmeric and Licorice are often used.
Lymphatics — support natural detox and recovery by helping the body move waste and immune by-products efficiently. Calendula and Dandelion are amongst Julia's favourites.
The best immune formula is never a one size fits all. Each person needs a unique blend based on current health, stress, digestion and any medications. Book an appointment if you'd like your own unique prescription.
However, we can all start supporting our immunity through food:
Garlic, onions and leeks — rich in allicin - antimicrobial and antiviral.
Mushrooms (Reishi, Shiitake, Maitake, Oyster) — contain beta-glucans to improve resilience.
Herbs & spices — Turmeric balances inflammation, Thyme & Oregano fight microbes and Ginger boosts circulation & clears congestion.
Citrus, berries & kiwi — high in vitamin C and antioxidants to protect tissues during illness.
Leafy greens — packed with folate, magnesium & chlorophyll to keep immune cells functioning efficiently.
Nuts & seeds — rich in zinc (for immune cell growth) and vitamin E (for protection).
By weaving these foods into your meals, you’ll be giving your immune system the raw materials it needs to stay balanced, responsive and resilient this season.
We’d love to hear in the comments your favourite ways to enjoy these immune supporting foods!
