Your Immune System Doesn’t Wait For Winter. 

Neither should you…. 

There is a chilly nip in the air. 

I can see a definite change in the character of my garden, now the busy harvesting of spring and summer is over. Stems dry, seeds harden, berries ripen, and roots draw their strength back underground. Nonetheless, I head outside with a basket, to see what remains to make myself an immune boost mix, ready for winter. 

One of the simplest and most satisfying ways to preserve this moment is by making an herbal vinegar. Vinegar is a fine extractor of minerals, vitamins, and plant actives. It captures the living quality of the plants in a form that can be used every day in food or as a tonic. This is practical, domestic medicine; quietly strengthening, inexpensive, and entirely my own. 

You can make your own immune boost. 

I Use Apple Cider Vinegar. Why? 

Raw, unfiltered apple cider vinegar with the ‘mother’ still present is not just a solvent but a medicine in itself. Its mild acidity draws minerals from plants, stabilises vitamin C, and helps preserve delicate compounds that water or alcohol might destroy. It supports digestion by stimulating stomach acid and bile flow, balances blood sugar, and brings a gentle anti-microbial action. 

If the vinegar is unpasteurised, it also contains beneficial bacteria that encourage a healthy gut flora. In energetic terms, it is mildly warming and dispersing—an excellent carrier for herbs that support circulation, immunity, and cleansing. 

What to Gather 

Even now, there is plenty available if you look carefully. Pick what you have in your garden, or can find on a walk [unsprayed areas away from roads]. A few leaves, a handful of flowers, or a small cluster of berries is enough. 

And you can also add stuff you have in the kitchen, like a cinnamon stick or slices of fresh ginger or garlic. 

As I wandered round my garden in the second week of October, what did I find? 

Mineral-Rich Greens 

These build strength and resilience through winter. 

• New growth nettle leaf or seeds: rich in minerals, supports adrenal function and steady energy. 

• Dandelion leaf or root: tonic to the liver and digestion, gently cleansing. 

• Chickweed: cooling, soothing, and highly mineralised. 

• Yarrow leaves: circulatory tonic, balancing heat and cold. 

Flowers for Healing and Colour 

These brighten the jar and lend lymphatic and emotional support. 

• Calendula: promotes tissue repair and lymph flow. 

• The last of Autumn Lavender: calm nerves and digestion. 

• Rose hips: antioxidant, vitamin C, and uplifting to mood. 

Roots and Warmers 

These bring warmth, movement, and immune protection. 

• Ginger root: anti-inflammatory, antimicrobial, supports circulation. [Added from my kitchen]. 

• Horseradish or nasturtium seed pods: pungent and clearing to sinuses and chest. [I used some Nasturtium vinegar I had made earlier]. 

• Garlic: a broad-spectrum antimicrobial and circulatory stimulant. [From my kitchen]. 

Berries and Fruit 

Rich in antioxidants and vitamin C, these strengthen immunity and lend a touch of sweetness. 

• Elderberries: antiviral and supportive to the respiratory system. [From my dried stash in my pharmacy]. 

• Rosehips: high in vitamin C and restorative to connective tissue. 

• Orange peel: aromatic, digestive, and uplifting. [I buy organic oranges and dry the peel]. 

Making Your Vinegar 

1. Fill a clean glass jar halfway with your chopped herbs, berries, and roots. 

2. Pour apple cider vinegar over them until the jar is full, making sure everything is covered. 

3. Label with the date and ingredients. 

4. Cover with a plastic lid or use parchment under a metal one. 

5. Leave to steep in a cool, dark place for three to four weeks, shaking occasionally. 

6. Strain through muslin and bottle. 

The vinegar will keep for up to a year. 

How to Use It 

Take one or two teaspoons daily in warm water or add a splash to a cup of herbal tea. Use it in salad dressings or drizzle it over cooked greens and vegetables. Mixed in equal parts with honey, it becomes a delicious oxymel for daily immune support. Diluted with warm water, it can be used as a gargle for sore throats or as a soothing compress for the skin. 

The Energy of the Season 

Autumn asks us to draw inward, to consolidate rather than expand. Making a garden vinegar is a small act of alignment with that rhythm. The sharpness of the vinegar balances the richness of the season, while the herbs remind the body how to adapt—warming where there is chill, cleansing where there is congestion, and nourishing where there is depletion. 

If you make only one jar this week, try a simple combination of rosehips, ginger, calendula, and orange peel in apple cider vinegar. It is bright, fruity, and sustaining—a tonic for body and spirit, and a way of keeping a little of the garden’s light alive through the dark months ahead. 

Let me know if you have made a mineral/immune vinegar, or of you hope to do so. This sort of activity satisfies the alchemist in one, and positively contributes to the health of our friends and families.
