The evidence in words
The verdict
For gut/immune (clinical), Oregano Oil earns evidence grade D (unclear effect, low consistency) — the evidence does not support the claim. Lab-dominated
How it might work
Carvacrol disrupts microbial membranes in vitro; whether meaningful antimicrobial levels are reached in the human gut is unclear.
How to use it
Safety & cautions
Irritating to mucosa; dilute; not for pregnancy or long-term use.
Bottom line
Strong in a petri dish, unproven in people, and harsh. Not a reliable gut or immune remedy.
