Understanding Influenza and Its Various Strains
Influenza or "the flu" is a highly contagious respiratory illness caused by influenza viruses. There are four types - A, B, C and D with influenza A and B responsible for seasonal flu outbreaks each year. The flu is characterized by sudden onset of fever, chills, body ache, fatigue, cough, headache, sore throat and runny nose.
How Flu Spreads and Peak Activity Periods
The flu spreads easily through tiny droplets when infected people talk, sneeze or cough without covering their mouth. Sharing personal items like utensils or shaking hands can also transmit the virus. In the US, flu viruses start circulating actively in Fall, peak during Winter months and can last until Spring causing yearly seasonal epidemics.
According to CDC estimates, there are 9-41 million flu cases annually leading to 140,000-710,000 hospitalizations from complications like pneumonia, worsening of chronic conditions, sepsis, organ failure etc. The flu can be dangerous in high risk groups like older adults, very young children, pregnant women and those with other medical problems.
Benefits and Modes of Action of Common Natural Remedies
While preventing the infection via vaccination remains the best approach, certain dietary supplements and natural ingredients have shown decent potential in relieving flu symptoms and shortening duration. However, most of the evidence comes from singular studies that warrant more research.
1. Zinc Lozenges
Zinc is critical for immune health and has natural antiviral effects. Some studies note sucking on zinc lozenges providing up to 100 mg zinc daily around onset of flu symptoms can accelerate recovery by 1-3 days. It may work by preventing viral replication inside cells and modulating the immune response.
2. Elderberry Syrup
Elderberry or Sambucus nigra preparations like syrup made from fruit contain antioxidants called anthocyanins. These promote immune response by increasing cytokine production which may interfere with flu virus entry, replication and spread. However, more research is required to confirm benefits.
3. Vitamin D Supplements
Vitamin D signals gene expression critical for the innate immune system including antimicrobial peptide production and macrophage activation. Correcting deficiency may aid recovery by modulating inflammatory signals that worsen flu symptoms. Dosage for acute infections is 4000-5000 IU daily for a week.
4. Garlic
Garlic has antimicrobial, anti-inflammatory and antioxidant effects. Compounds like allicin may block enzymes viruses require for entry and limit cytokine storm from exacerbated host response. Fresh garlic, aged garlic extract or garlic oil supplements seem to provide modest benefits for flu.
5. Andrographis
Andrographis paniculata is an herb used in Ayurvedic and Chinese medicine. Its active component andrographolide exhibits anti-inflammatory, antiviral and immune regulating actions. Double blind studies reveal significantly faster time to recovery and reduced symptom scores for influenza with andrographis use.
6. Pelargonium
Pelargonium sidoides root extract displays immunomodulatory activity and helps alleviate bronchitis symptoms. Limited trials report some reduction in duration and severity of uncomplicated common cold and flu with pelargonium within first 48 hours when taken for 10 days if strong quality evidence.
Other Natural Flu Home Remedies
Apart from the most researched ones above, several other natural ingredients and kitchen items tend to provide comfort from flu misery even if robust data is unavailable regarding efficacy against infection itself.
7. Hot Soups and Broths
Warm broths, chicken soups and vegetable soups temporarily ease stuffy nose, soothe sore inflamed throat and provide hydration during illness. Adding spices like garlic, turmeric and ginger provides additional anti-inflammatory, antioxidant boost.
8. Honey
Honey has antimicrobial properties attributed to enzymatic production of hydrogen peroxide plus healing benefits for sore throat. Mixed with herbal tea or lemon water, it can relieve cough and help patients rest. Not for children under one year due to infection risk.
9. Steam Inhalation
Breathing steam loosens nasal secretions drainage from sinuses, moisturizes dry irritated throat and nasal passages. Add menthol, eucalyptus or camphor oil to amplify congestion relief. Helps control cough spells and improves rest.
10. Marshmallow Root
Dried marshmallow root made into cold infused tea works as emollient mucilage coating throat membranes, reducing irritation and cough. Also has antioxidants. Store-bought cough syrups use similar principles.
11. Peppermint Tea
Menthol present in peppermint acts as decongestant, helps thin out mucus secretions and clears upper respiratory tract. Sipping warm peppermint tea gives temporary alleviation from stuffed nose and chest during flu.
Precautions with Natural Flu Remedies
While these home remedies derived from food sources or herbal extracts are relatively safer compared to medications when used judiciously, some considerations apply for certain groups:
- Consult doctor before giving any herbal self-medication to young children or during pregnancy/breastfeeding
- Choose reliable brands following good manufacturing practices for supplements
- Check product packaging for potential allergy triggers like soy, gluten or nightshade family plants
- Avoid remedies that can worsen gastritis like garlic, ginger, pepper in those with GI issues
- Discontinue use if any side effects like rash, abdominal pain, diarrhea, insomnia etc appear
Additionally, these natural products should not replace standard medical treatment when professional help is warranted for severe flu symptoms or high risk individuals. Anti-virals like Tamiflu may still be indicated in certain hospitalized or immunocompromised patients based on physician discretion.
Boosting Immune Resilience For Prevention
Aside from managing flu illness, proactively strengthening immune resilience with healthy lifestyle habits makes us less susceptible to infections in the first place. Key strategies include:
- Balanced nutritious diet with fruits, vegetables, lean protein, probiotics
- 7-8 hours good quality sleep nightly
- Regular physical activity as per tolerance
- Stress management via relaxation techniques
- Quitting smoking, avoiding secondhand smoke exposure
Setting yearly influenza vaccination also goes a long way in priming our immune system against the high mutating flu viruses expected during upcoming cold seasons, especially for those at higher risk of complications.
Natural remedies can provide comforting adjunctive symptom relief when dealing with uncomplicated flu cases. However sensible lifestyle choices supporting overall wellness provide the best line of defence to help drastically cut down flu susceptibility and associated miseries year after year.
FAQs
What are the best natural flu remedies supported by some research?
Zinc lozenges providing up to 100mg elemental zinc per day, elderberry syrup, high dose vitamin D supplements (4000-5000 IU), garlic supplements, andrographis paniculata and pelargonium sidoides root extracts have shown some evidence of shorter duration and reduced severity in a few studies.
How can chicken soup help with flu?
Warm chicken broth can temporarily relieve congestion and soothe sore inflamed throats. Adding garlic, turmeric and ginger provide additional anti-inflammatory and antioxidant effects though minimal direct antiviral properties. The hydration also prevents dehydration from fever, sweating and poor intake during illness.
When should you avoid natural flu remedies?
Avoid natural remedies if you have any underlying conditions without physician approval first or if you experience any intolerance symptoms like rash, diarrhea or abdominal discomfort. Discontinue use if existing symptoms worsen after starting any new natural product and seek medical care if fever is excessively high or persists beyond 3 days.
Do these natural products replace flu shots?
No, while some natural remedies provide modest relief from flu symptoms, they do not replace the immunity boosting protection from annual flu vaccinations. Flu shots remain the most effective way to lower infection risk and prevent severe complications based on predicted viral strains especially in high risk groups like older adults, pregnant women, young infants.
