The flu, a viral infection affecting the respiratory system, can be managed naturally by supporting the body's immune system. Explore terrain theory, immune-boosting foods, hydration, and homeopathic remedies to aid recovery. This article offers practical tips to empower your body to heal itself and combat the flu effectively.
What is the flu?
The flu, or influenza, is traditionally considered a viral infection that primarily affects the respiratory system. Recently, a different perspective called terrain theory has been discussed. Terrain theory is the idea that the body’s overall internal environment, including nutrition, gut health, immune strength, and toxin levels that plays a crucial role in determining whether a person becomes ill and how well they recover. Instead of focusing only on the virus itself, terrain theory suggests that a healthy, balanced internal environment is less likely to allow illness to take hold. This approach views symptoms as helpful signals from the body, showing it is working to cleanse, balance, and restore itself, not just as negative effects of a virus.
Viewed through either a viral or terrain lens, the flu activates the body’s natural defences. Symptoms are part of a purposeful healing response, not just effects to be suppressed.
Common flu symptoms
Fever or chills
Muscle and body aches
Sore throat or cough
Headache
Profound fatigue
Reduced appetite
Stomach flu or gastroenteritis: vomiting, diarrhoea, abdominal cramps, nausea
Clinically, I have noticed that this flu season, patients are either experiencing stomach flu or respiratory flu, with a lingering cough lasting several weeks.
My natural therapeutic approach is designed to help alleviate individuals' presenting symptoms, support immune system health, and provide respiratory relief, as reflected in the testimonial below.
Patient testimonial
"Tina Horrell was very knowledgeable, professional, asked lots of questions, and had a great sense of humor. She got me feeling better in two days from a nasty three-week battle with breathing difficulties from the flu."
Fever: The body’s protective mechanism & natural support
Fever is not an illness, but a natural defence mechanism. The number on the thermometer is just one aspect. Observing how the individual looks, behaves, breathes, their appetite, and responses is often more important than the temperature alone.
"Give me the power to produce fever, and I’ll cure all disease." – Parmenides, 5th century BC.
This quote reflects the belief in the therapeutic potential of fever, recognising it as a powerful physiological response that could be harnessed for healing.
Fever creates an internal environment that slows the growth of both bacteria and viruses while simultaneously enhancing immune cell activity, making it one of the body’s most effective natural defence mechanisms.
Tylenol and fever: Risks you should know
Acetaminophen (Paracetamol/Tylenol) is widely used, yet overuse is dangerous:
It’s the leading cause of acute liver failure and the number one cause of liver transplant in the US.
It is found in over 500 products, including cold/flu combinations.
Taking multiple products simultaneously may exceed safe limits.
The Tylenol company’s social media account in March 2017 stated that they don’t recommend using any of its products during pregnancy. On the safety page of their website, Tylenol recommends asking a health professional before use if pregnant and breastfeeding.
A Harvard study reported that acetaminophen use during pregnancy may be linked to a higher risk of autism and ADHD in children. Prada, Diddier, et al. “Evaluation of the Evidence on Acetaminophen Use and Neurodevelopmental Disorders Using the Navigation Guide Methodology.” Environmental Health, vol. 24, Article 56, 14 Aug. 2025, doi:10.1186/s12940-025-01208-0.
Natural philosophy
Natural medicine prioritises prevention and respects symptoms as meaningful biological signals. Rather than suppressing them, it works with the body’s innate intelligence – supporting the healing processes already underway and strengthening the body’s capacity to regulate, repair, and restore balance.
Many now ask: How can we best support the body so it is better prepared to respond to illness in the first place?
A preventative approach recognises that the immune system is intelligent, adaptive, and influenced by nutrition, lifestyle, and how we respond to natural signals like fever.
5 ways to boost your immune system naturally
A strong immune system helps prevent infections, reduce symptoms, and speed recovery. Deficiencies in key nutrients such as vitamin D, vitamin C, zinc, and selenium raise susceptibility to illness.
1. Nourish with key ingredients
Vitamin C supports the immune system naturally. A lack of vitamin C increases the susceptibility to viruses and increases the severity of the infection. Found in: citrus, berries, kiwi, red capsicum, broccoli, kale, spinach.
Vitamin D has a role in immune modulation, it stimulates antimicrobial peptides and has receptors on immune cells, suggesting it supports both innate and adaptive immune responses. Fasano, A., and John H. White. “Vitamin D, Infections and Immunity.” Reviews in Endocrine and Metabolic Disorders, 2022, Found in fatty fish, egg yolk, cheese, mushrooms, and sunlight. I also recommend a combined vitamin K2 and vitamin D3 supplement. Some research indicates potential roles in reducing inflammation and supporting immune responses.
Zinc helps regulate and support the immune response. Found in: oysters, sardines, eggs, seeds, garlic, and buckwheat.
Phytonutrients and antioxidant-rich foods help the immune system by protecting immune cells from damage and keeping them working efficiently. They also help calm excessive inflammation and support a balanced immune response, so the body can fight infections without overreacting. Found in: colourful fruits and vegetables such as berries, carrots, beetroot, broccoli, pineapple, citrus, papaya, and leafy greens.
2. Immune-boosting superfoods
Raw honey & bee pollen: antioxidants and immune-modulating
Probiotics: fermented foods like kimchi, sauerkraut, kefir, miso, tempeh
Probiotics contribute to gut immunity, which comprises approximately seventy percent of the immune system.
Elderberry: traditionally used for respiratory support and antiviral benefits
Medicinal mushrooms:
Shiitake: B vitamins, selenium
Chaga: antioxidants, zinc
Reishi: reduces inflammation
Turkey tail: supports white blood cell activity
3. Stay hydrated
Hydration is critical for lymphatic flow, detoxification, and immune efficiency. Hydration is especially important during fever or vomiting.
Flu-friendly fluids include:
Warm water with lemon, ginger, garlic, and honey
Fresh vegetable juices with ginger
Soups and broths combining vegetables, herbs, and spices provide nutrients in their most bioavailable form.
4. Herbs & spices
Support immunity naturally with medicinal & kitchen herbs:
Herbal teas for respiratory support: elderberry, peppermint, yarrow, licorice
Garlic, turmeric, ginger, oregano, thyme
Warming spices: black pepper, cayenne, chilli
5. Supporting lifestyle habits
Limit sugar and dairy products.
Reduce refined carbohydrates and highly processed foods.
Combine nutrient-rich meals with rest and hydration.
In my clinical practice, I routinely combine recommendations for rest, hydration, immune-supportive herbs and nutrition, and homeopathic remedies for optimal results.
Homeopathy and flu support
Homeopathy is a system of medicine that individualises treatment based on a person’s individual symptom picture rather than a disease label.
Commonly used remedies include:
Aconitum napellus: for sudden onset, anxiety, restlessness, worse from cold wind
Belladonna: for sudden high fever, flushed face, throbbing
Gelsemium: for weakness, desire to lie still, comes on slowly
Bryonia: for dryness, irritability, wants to be left alone, worse from movement
Arsenicum album: for prolonged chills, gut symptoms, anxiety
Another patient experience
“Tina is great, and I highly recommend her. I consulted Tina because I had symptoms that correlated with COVID-19. I was waking up in the night feeling like I couldn’t breathe, my chest felt tight, I had a sore throat, felt very tired, had a fever that came and went, and I was very fearful. Within a few days after using the recommended homeopathic medicine and following Tina’s suggestions on diet, inhalations, rest, and vitamins, my anxiety and physical symptoms lessened, and I recovered well. Apart from the fact that I think Tina is an excellent homeopath and naturopath, I experienced Tina's care and attention like a warm bath. She is very steadfast and really went the extra mile to make sure I was okay. I can wholeheartedly recommend her to you."
Small steps like staying hydrated, including colourful foods in meals, resting, and using gentle natural supports can make a significant difference this flu season. Empower yourself with knowledge, and support your body’s natural abilities to heal.
