Other herbs sometimes mentioned include:
Garlic
Wormwood
Black walnut
Goldenseal
Thyme
But oregano appears most frequently because it has been studied more extensively for antimicrobial properties.
Let’s explore why.
Oregano: Why It’s Called “Potent”
Oregano (Origanum vulgare) contains two compounds that researchers pay close attention to:
Carvacrol
Thymol
These compounds have demonstrated:
Antibacterial activity in lab studies
Antifungal effects
Some antiviral activity in vitro
Activity against certain parasites in experimental settings
This is where the reputation comes from.
But there’s an important caveat:
Laboratory activity is not the same as clinical treatment in humans.
Parasites: What Herbs Can and Cannot Do
Some herbs have traditionally been used to support the body during parasitic infections.
Examples include:
Wormwood
Black walnut hull
Clove
Garlic
In laboratory or traditional contexts, these herbs may:
Create an environment less favorable to parasites
Support digestion and immune response
However, doctors are very clear on this point:
Confirmed parasitic infections require medical diagnosis and targeted treatment.
Herbs may play a supporting role, but relying on them alone can delay effective care and cause harm.
