Kill a Cold

My previous method of stopping a cold in its tracks involved taking every antimicrobial and antiviral herb I could find in a bid to halt the infection.
However, my recent experience with COVID has led me to adopt a more cautious and nurturing approach.
While my old method was largely effective, I now realise that I was overlooking several important aspects of
the healing process, which ultimately prolonged my recovery. In this post, I’ll share how I now prevent a cold from taking hold and the steps I take to ensure a faster recovery if I do fall ill.
Early Signs of a Cold
The first signs of a seasonal cold are usually a runny nose, sore throat, or cough. You may even have felt fatigued in the days leading up to these symptoms—a clear sign that your body is fighting something.
Colds are most commonly caught when a virus enters through the nasal passages, so one of my first actions is to flush my nostrils regularly with a saline nasal spray. This can help reduce inflammation and potentially weaken the virus. An antiviral nasal spray can also be beneficial.
The back of the throat is another hotspot where viruses and bacteria accumulate. Gargling with salt water can make it harder for them to survive and spread.
Key Supplements for Immune Support
Next on my list is high-dose vitamin C. Studies have shown that high doses of vitamin C can reduce the severity and duration of the common cold. When I’m unwell, I may take up to 5,000 mg of liposomal vitamin C throughout the day. Liposomal vitamin C is encapsulated in tiny fat-like particles called liposomes, which enhance absorption and bioavailability, making it more effective than standard vitamin C supplements.
Please note: The recommended daily dose of vitamin C is typically between 100 mg and 500 mg. I am only able to tolerate a higher dose because I have worked under the guidance of a natural health professional. Please do not take high-dose vitamin C without professional advice.
The following vitamins also play a crucial role in supporting a healthy immune system. I always make sure to take these in addition to vitamin C:
Vitamin D
Vitamin A
Vitamin E
Vitamin B6
Vitamin B9 (Folate)
Vitamin B12
Vitamin K
Powerful Antiviral Herbs
Herbs have been used for centuries to treat the common cold, yet people often underestimate their power when tackling viral or bacterial infections. Not only can herbs help weaken a virus, but they can also boost the immune system, kill bacteria, and reduce inflammation.
I’ve used the following herbs to combat not only the common cold but also Lyme disease and Epstein-Barr virus:
Echinacea
Elderberry
Astragalus
Garlic
Ginger
Oregano
Lemon Balm
Andrographis
Thyme
Liquorice Root
Peppermint
Cat's Claw
If I feel a cough developing, I inhale peppermint, oregano, and eucalyptus essential oils. This is particularly useful for chest infections that are stubborn and difficult to clear. These oils are potent, so please only use them after consulting a health professional.
Avoiding Immune Suppressors
In addition to taking supplements, I make a conscious effort to avoid anything that could suppress my immune system. Sugar, processed foods, and alcohol all have a detrimental effect on immunity. High sugar intake temporarily weakens the immune system by reducing the effectiveness of white blood cells, making it harder for the body to fight off infections. This effect can last for several hours after consuming sugar.
Digesting food requires a lot of energy, so eating soups and bone broth helps free up the body's resources, allowing it to focus on fighting the infection.
This is my tried-and-tested formula for beating a cold. However, as I previously mentioned, my approach has changed slightly following my recent experience with COVID.
My COVID Experience
At the first signs of feeling unwell, I started my usual protocol. After a couple of days, I felt better. However, two weeks later, I became sick again—this time, it took even longer to recover. For three months, I found myself stuck in a cycle of feeling better, only to fall ill again.
My approach of taking immune-boosting herbs and vitamins had triggered immune hyperactivity. A hyperactive immune system is not necessarily an effective one. While tackling a cold early can be beneficial, sometimes not allowing it to run its natural course can lead to bigger problems. After all, a cold is often a sign that the body is run down and needs rest.

Had I taken time to properly rest and gently support my body, I would have fully recovered without experiencing repeated relapses. And this is why rest and relaxation are so important when it comes to a healthy immune system.
Relaxation is crucial for the immune system because chronic stress triggers the release of cortisol, which can suppress immune function and increase inflammation. When the body is in a relaxed state, it activates the parasympathetic nervous system, allowing for better immune regulation, reduced inflammation, and improved recovery from illness.
My Approach Now
I make sure to listen to my body. High-dose vitamin C, proper nutrition, and rest are my top priorities. If my immune system needs a little support, I use herbs—but with caution.
