Common cold/influenza remedies?

You can always use saline nasal spray. Best to find one without all the preservatives.

I’ve been doing this 3x a day.

I have stated this in other posts as well but l have found Methylene Blue to be very effective against viruses.

These suggestions have helped a lot! I feel like this thread will accumulate a lot of great tips and tricks for people to try out when they inevitably get a cold/flu.

I didn’t use the steroid/antihistamine nasal spray today and I can just breathe through my nostrils way better. I’m thinking I’ll skip the decongestant nasal spray tonight.

Also when I cough it isn’t as intense.

Maybe I need to make high dose vitamin C a regular thing even when I’m not sick?

Any tips for blocked eustachian tube? My ears feel less clogged today I guess that will go away over time.

Be mindful of high dose things like amino acids, vitamins, minerals as it can lower/reduce other things.
Such as high dose zinc or vitamin c lowering copper.
If using NAC, some companies add in co-factors like selenium and molybdenum.
I did not see anyone recommend selenium, but some recommend 200mcg - 800mcg if very sick - along with other supplements of course.

A multi vitamin and mineral is a good base to balance out things if you are going to go high on certain products… to keep things from not getting too low etc.

There are other good products on the market that people have mentioned.
Anti-biotics, anti-virals, herbal extracts etc might help in various situations.

Thymosin alpha 1, a peptide with a wide range of biological properties, has been observed to boost resistence to the flu, the cold, hepatitis, covid, and sepsis.

I had my Dr. write me a prescription for Xofluza so i have it on hand asap if i test positive for flu. Allegedly more effective than Tamiflu.

Sounds good. How do you know if you have cold or flu?

take a test which are available in the us over the counter

Hi Lar, welcome to our site. We are a science and evidence-based website. Please don’t post information or links to homeopathic “medicines”. Unfortunately there is not medical or scientific evidence that homeopathic solutions have any benefit. Unless you have solid scientific evidence for any product or therapy you are discussing here, it’s best to avoid posting commentary. See this summary for more information:

I ran your statement through Google Gemini’s AI system to evaluate the scientific and medical support for those products and here is what it came back with:

Scientific Evaluation: Homeopathic Influenza Protocols

The statement provided is scientifically invalid and clinically unsupported. The regimen described—using Influenzinum for prophylaxis and Oscillococcinum for acute treatment—relies on homeopathic principles that contradict established pharmacology, immunology, and physics.

From a biotech and longevity perspective, relying on these compounds for viral suppression introduces a significant “opportunity cost” risk, potentially displacing proven immunomodulatory interventions.


1. Influenzinum for “Flu Avoidance” (Prophylaxis)

Claim: Taking Influenzinum (a homeopathic dilution of influenza strains) prevents infection.
Verdict: Biologically Implausible / No Efficacy.

  • Absence of Active Ingredient: Homeopathic remedies like Influenzinum are typically diluted to 9C or 30C. Beyond $12C$ (the Avogadro limit), the statistical probability of a single molecule of the original substance remaining in the solution is effectively zero.
  • Immunological Failure: Vaccination works by presenting an antigen (attenuated virus, protein subunit, or mRNA) to the immune system to stimulate the production of IgG and IgA antibodies and memory T-cells. Influenzinum contains no antigens. Consequently, it cannot induce seroconversion or specific immune memory.
  • Clinical Data: There are no peer-reviewed, double-blind, randomized controlled trials (RCTs) demonstrating that Influenzinum offers protection against the influenza virus superior to placebo.
  • Regulatory Stance: Health authorities, including the FDA and the CDC, explicitly state that homeopathic products are not substitutes for vaccination and offer no proven protection against flu.

2. Oscillococcinum for “First Chills” (Treatment)

Claim: Oscillococcinum suppresses symptoms if taken at the onset of illness.
Verdict: Weak to Non-Existent Evidence.

  • Source Material: The “active” ingredient is Anas barbariae (Muscovy duck) heart and liver autolysate. The theory (from 1917) incorrectly assumed duck offal contained “oscillococci” bacteria that caused flu. This bacteria does not exist; flu is viral.
  • Dilution Physics: The standard preparation is 200CK ($1$ part substance to $10^{400}$ parts solvent). To consume one molecule of the duck liver, one would need to consume a mass of sugar pills greater than the mass of the observable universe.
  • Cochrane Review Data: A systematic review by the Cochrane Library (Mathie et al.) analyzed RCTs involving Oscillococcinum.
    • Result: It showed no evidence of preventing influenza.
    • Result: For treatment, it showed an absolute reduction in illness duration of approximately 0.28 days (less than 7 hours), which was deemed clinically insignificant and potentially due to bias in study design.

3. Analysis of the Anecdote (“We just don’t catch the flu”)

The user statement “We just don’t catch the flu” is a classic example of Confirmation Bias and Survivorship Bias.

  • Base Rate Neglect: Depending on the severity of the season, only 5% to 20% of the population contracts influenza annually. Therefore, 80-95% of people doing nothing (or taking sugar pills) will effectively “avoid” the flu.
  • Asymptomatic Infection: Approximately 30% of influenza infections are asymptomatic. An individual may contract the virus, mount an immune response, and clear it without realizing they were infected.
  • Placebo Effect: The perception of wellness is heavily influenced by the placebo effect, which can modulate subjective symptoms (pain, fatigue) but does not alter viral load or pathology.

Summary of Scientific Consensus

Feature Homeopathic Flu Regimen Standard Medical Standard (Biotech)
Active Compound None (Sugar/Lactose carriers only) Antigens (Vaccines) or Neuraminidase Inhibitors (e.g., Oseltamivir)
Mechanism “Like cures like” / Water memory (Pseudoscience) Adaptive Immunity / Viral Replication Inhibition
Pharmacokinetics None (Bioavailability is irrelevant for sugar) Measurable absorption, distribution, metabolism, excretion
Efficacy Indistinguishable from placebo Statistically significant reduction in morbidity/mortality

Actionable Insight for Longevity & Immunity

If the goal is genuine biological resilience against viral pathogens, redirect focus from homeopathy to compounds with verified pharmacodynamics:

  1. Vitamin D3 Status: Maintain serum 25(OH)D levels between 40–60 ng/mL. Vitamin D regulates the expression of cathelicidin and defensins (antimicrobial peptides). PubMed Ref
  2. Zinc Ionophores: Zinc inhibits RNA-dependent RNA polymerase (viral replication). Quercetin or EGCG act as ionophores to transport zinc intracellularly.
  3. N-Acetylcysteine (NAC): Precursor to Glutathione. Validated to reduce mucin viscosity and oxidative stress during viral infection. PubMed Ref

Verdict: The statement is scientifically baseless. The perceived efficacy is attributable to the placebo effect and the naturally low statistical incidence of symptomatic influenza in the general population.

TA1 is a good idea, SKYE peptides is not.
Check out a quick google search for reviews shows FDA violations, and Trustpilot.com has review of people getting sick on their stuff.

Garlic extract drops are good.

This might work for some but from my experience (with this specific one and with several peptides, they appear to be money down the drain, unless effects are subtle and not supposed to manifest while you take them. I suspect that either I’m non-responsive to peptides or people are reporting placebo effects. The only ones with clear effects for me are GLP1’s, HGH, and HCG. I got nothing from BPC, TB500, thymosin A, Thymolin and many other peptides I tried (about 15-20)

I’ve had the same experience with peptides for the most part.

Is water fasting during a cold a bad idea? I was thinking of doing a 1 day fast.

Thanks for the feedback.
