Can Apple Cider Vinegar Kill Parasites?

Can Apple Cider Vinegar Kill Parasites?

Quick Answer: Apple cider vinegar (ACV) is sometimes promoted as a natural remedy for parasites, but there’s no solid scientific evidence that it can kill internal parasites in humans. However, ACV’s acidity and antibacterial properties may help with certain microbes, and it has some uses for external parasites.

What Are Parasites?

Parasites are organisms that live off a host. Common types include:

  • Intestinal parasites (tapeworms, roundworms)

  • Protozoa (Giardia, amoebas)

  • External parasites (lice, mites, fleas)

They can cause digestive issues, fatigue, itching, and more serious health problems if untreated.

ACV and Internal Parasites

  • The Claim: ACV makes the gut more acidic, which supposedly discourages parasites.

  • The Science: There’s no clinical evidence that ACV kills worms or protozoa in the human gut.

  • Reality: If you suspect parasites, medical diagnosis and treatment are essential.

ACV and External Parasites

Where ACV may help:

  • Lice & Fleas: Some people use diluted ACV as a rinse on hair or pets to discourage pests.

  • Mites: ACV sprays are sometimes used for skin irritation caused by mites.

  • Why It Works: The acidity and smell may repel pests, but it doesn’t reliably kill them.

Safe Ways to Use ACV

  • Internal Use: 1–2 tablespoons diluted in water daily may support digestion and gut health, but won’t treat parasites.

  • External Use: As a hair rinse or spray for pets (always diluted).

Risks of Over-Reliance

  • Delaying medical care for true infections can be dangerous.

  • Overusing ACV internally can cause stomach upset, enamel erosion, or throat irritation.

  • Not safe as a sole treatment for diagnosed parasitic infections.

The Bottom Line

Apple cider vinegar has many wellness benefits, but it’s not a proven cure for parasites. It may support digestion and repel some external pests, but medical treatment is required for true infections.
