Acute infection — antivirals & antimicrobials
One of 5 mechanistic pathways to 🛡️ Immune resilience · 15 options
Different from prevention. These aim to shorten or blunt an infection in progress, and timing dominates efficacy — most of them only work if started within the first day or two.
The differential white count separates viral from bacterial better than how you feel does — and it decides whether anything in this pathway is even the right category.

What engages this pathway
Ordered by how directly each one acts on the mechanism above — never by how much trial evidence exists. Each links to its full breakdown with dosing, half-life and vendor.
🧬 Elderberry
Anthocyanins appear to block viral haemagglutinin entry. Meta-analysis supports reduced duration of upper-respiratory symptoms when started early.
🧬 Zinc
Zinc lozenges reduce common-cold duration by roughly a third in meta-analysis — but only ionic zinc, only lozenges dissolving in the throat, and only started within 24 hours. Most products fail at least one of those conditions.
🧬 Vitamin C
Does not prevent colds in the general population; does modestly shorten them, with a larger effect in people under heavy physical stress.
🧬 L-Lysine
Competes with arginine, which herpes viruses need to replicate. Trial evidence for reduced HSV recurrence frequency.
🧬 Monolaurin
Disrupts lipid envelopes of viruses and some bacteria in vitro.
🧬 Olive Leaf Extract
Oleuropein with antiviral activity in cell models.
🧬 Andrographis
Meta-analysis supports symptom reduction in upper-respiratory infection; one of the better-evidenced botanicals here.
🧬 Echinacea
Trial results are genuinely mixed and species- and preparation-dependent. Purpurea aerial-part extracts performed best.
🧬 Propolis
Antimicrobial and antiviral bee resin with trial evidence in upper-respiratory infection and oral lesions.
🧬 Manuka Honey
Methylglyoxal-driven antibacterial activity with real wound-care evidence and cough-suppression data.
🧬 Oregano Oil
Broad-spectrum carvacrol activity; hard on commensals with prolonged use.
🧬 Cat's Claw
Immunomodulatory alkaloids with traditional use in viral illness.
🧬 Black Seed Oil
Thymoquinone with antimicrobial and anti-inflammatory trial data across several conditions.
🧬 Vitamin D
Prophylactic supplementation reduces acute respiratory infection; large bolus dosing during an infection does not appear to help.
💉 Thymosin Alpha 1
Used as an adjunct in severe viral illness in several countries; it modulates rather than suppresses.

Frequently asked questions
Different from prevention. These aim to shorten or blunt an infection in progress, and timing dominates efficacy — most of them only work if started within the first day or two.
15 options are mapped to this pathway in the Vault, including Elderberry, Zinc, Vitamin C, L-Lysine. They are grouped by the mechanism they act through rather than ranked by how much trial evidence exists — 11 carry clinical validation and 4 are mechanistic predictions.
The differential white count separates viral from bacterial better than how you feel does — and it decides whether anything in this pathway is even the right category. The markers worth checking are Complete Blood Count (CBC) with Differential, hs-CRP (High-Sensitivity C-Reactive Protein), ESR (Sed Rate), Vitamin D (25-Hydroxy).
Unproven is not the same as ineffective. Of the 15 options on this pathway, 11 have clinical validation and 4 are graded theoretical — meaning the mechanism is sound but the specific human trial has not been run, which is true of a great deal of what works in this space. Nothing on this page is ordered by evidence tier, because sorting by trial count would bury the compounds you came looking for.
