There's a moment every year - usually around the time the evenings draw in and the first jumpers come out - when we start thinking about winter sniffles. Autumn is the perfect time to take stock of your immune health, and herbal traditions across the world have long leaned on certain plants at this time of year. Here's a guide to six of the best-known immune-supporting herbs, what the research says, and how to use them.
1. Elderberry (Sambucus nigra)
A hedgerow classic here in the UK, elderberry has been used for centuries in syrups and cordials as a winter remedy. The berries are rich in anthocyanins — deep purple plant compounds with antioxidant properties. Some clinical studies suggest elderberry extract may help reduce the duration and severity of cold symptoms, though results are mixed and more research is needed.
How to take it: Syrups, gummies, and capsules are all popular. Note that raw elderberries shouldn't be eaten uncooked - always use properly prepared products.

2. Echinacea (Echinacea purpurea)
Perhaps the most famous immune herb of all, echinacea was traditionally used by Native American communities and became a staple of Western herbalism. Research on echinacea is extensive but inconsistent - some reviews suggest a modest reduction in the risk of catching a cold, while others find little effect. Many herbalists recommend taking it at the first sign of symptoms rather than continuously.
How to take it: Tinctures, capsules, and teas. Look for products made from the aerial parts or root of Echinacea purpurea.
3. Garlic (Allium sativum)
Humble, inexpensive, and genuinely well-studied. Garlic contains allicin, a sulphur compound with antimicrobial properties. One well-known trial found that people taking a daily garlic supplement over winter caught fewer colds than those taking a placebo. It also happens to make everything taste better.
How to take it: Fresh in cooking, or as aged garlic extract or odour-controlled capsules if you'd rather keep your breath sociable.
4. Gut Support: Probiotics for Immune Health
Not a herb, but arguably the most important entry on this list — because a large proportion of your immune system is located in and around the gut. A balanced gut microbiome helps train and regulate immune responses, which is why probiotics have become a cornerstone of autumn wellness routines. Three strains worth knowing:
- Lactobacillus rhamnosus — one of the most researched probiotic strains in the world, studied for its role in supporting gut barrier health and immune function, with some trials suggesting it may help reduce the occurrence of respiratory infections, particularly in children.
- Lactobacillus salivarius — a naturally occurring resident of the mouth and gut, studied for its ability to support a healthy oral and digestive microbiome, your first line of contact with the outside world.
- Bacillus coagulans — a hardy, spore-forming strain that survives stomach acid particularly well, making it a reliable choice for reaching the gut intact. It's been studied for digestive comfort and immune support.
How to take it: Capsules are the most common format. Look for products that state the strains and CFU count (colony-forming units) clearly, and take them consistently — probiotics work best as a daily habit rather than an occasional boost.
5. Astragalus (Astragalus membranaceus)
A cornerstone of traditional Chinese medicine, astragalus root is traditionally taken preventatively through autumn and winter — before illness strikes, rather than during it. Modern research is still in early stages, but it remains one of the most popular "deep winter preparation" herbs.
How to take it: Capsules or as dried root slices simmered into broths and soups.
6. Ginger and Turmeric
These warming kitchen spices deserve an honourable mention. Both contain compounds (gingerol and curcumin respectively) studied for their antioxidant and anti-inflammatory properties, and both make wonderfully comforting teas as the weather cools. Curcumin is poorly absorbed on its own, so look for supplements paired with black pepper extract (piperine).
How to take it: Fresh in teas and cooking, or as standardised extracts in capsule form.
Don't Forget the Foundations
Herbs work best as part of a bigger picture. As autumn sets in, the basics matter most:
- Vitamin D - the NHS recommends everyone in the UK consider a daily 10 microgram (400 IU) vitamin D supplement between October and March, since we simply don't get enough sunlight.
- Sleep - consistently short sleep is one of the most reliable ways to weaken immune defences.
- A colourful diet - seasonal vegetables, fruits, and fermented foods support gut health, where a large portion of your immune system lives.
- Movement and fresh air - regular moderate exercise supports healthy immune function.
The Bottom Line
No herb can promise you a winter without a single cold - anyone who says otherwise is overselling. But traditions old and new agree that autumn is the time to prepare, and supplements like elderberry, garlic, and a good daily probiotic offer a pleasant, sensible way to support your body through the darker months, alongside good food, good sleep, and a daily vitamin D.
