Parasites according to Hulda Clark
Dr. Clark was renowned for her expertise on parasites and was the first to recognize that parasites are not limited to tropical regions but can infest people worldwide. She discovered that parasites can significantly damage the human body by weakening the immune system and causing various diseases. Contrary to common belief, parasites are not limited to the adult stage or just the intestine; they can be found throughout the body and have become more prevalent due to globalization, which facilitates their spread.
Parasites consume our nutrients and release toxic substances, contributing to various health issues. Dr. Clark’s methods, such as Zapping and Parasite Cleanse, aim to remove over 120 species of parasites without side effects. For more persistent parasites, like ascaris and tapeworms, she recommended the Mop-up Program.

What is a Parasite?
A parasite is a tiny organism that lives on or inside another host, consuming its nutrients and releasing toxins.
Types of Parasites
- Protozoa: Microscopic, single-celled organisms like plasmodium and cryptosporidium.
- Helminths: Multicellular organisms visible to the naked eye, including flatworms (trematodes), tapeworms (cestodes), and roundworms (nematodes).
- Ectoparasites: Larger insects such as ticks, lice, and mites that transmit illness.
Common Flukes Mentioned by Dr. Clark:
- Fasciolopsis buski: Linked to intestinal issues and certain cancers.
- Fasciola hepatica: A liver parasite associated with Crohn’s disease and chronic fatigue.
- Eurytrema pancreaticum: A pancreatic parasite linked to diabetes and low immunity.
- Clonorchis: A liver parasite that can cause carcinoma of the bile ducts and liver.
- Paragonimus: A lung parasite associated with various infections.
Roundworms (Nematodes):
- Dirofilaria: Dog heartworm related to migraines and heart disorders.
- Ascaris: The largest intestinal parasite, affecting many people globally. It can cause a range of health issues, including joint pain and inflammation.
Tapeworms (Cestodes):
- Taenia solium: A tapeworm with a head (scolex) that attaches and absorbs nutrients. It can grow up to 7 meters and produce up to 50,000 eggs per segment.
Other Parasites:
- Schistosoma: Bladder parasites linked to bladder disorders.
- Ancylostoma: Causes anemia and joint pain by entering through the skin.
- Strongyloides: Associated with headaches and muscle pain.
- Enterobius vermicularis: A common intestinal parasite affecting millions worldwide.
- Trichinella: A muscle parasite from meat and pets, causing joint pain and associated with fibromyalgia.

Dr. Clark was the first to recognize the extensive parasitic infestations affecting us. Throughout history, humans have had parasites, and typically, our immune system should eliminate them. However, parasites often thrive and persist, particularly in their larval stages, due to various factors.
Parasites in food
Dr. Clark explains that, like humans, parasites have specific food preferences and have adapted more rapidly to environmental solvents and metals than their human hosts. They are also closely linked to food allergies.
This is problematic because parasites consume our nutrients—food, vitamins, and minerals—while releasing harmful substances like bacteria, metals, viruses, and toxins.

Healthy individuals generally have fewer parasites, while those who are sick tend to have more. Globalization impacts our food sterilization, water purification, and food supplement standards. To maintain health, it is crucial to revert to natural practices, prepare food from scratch, and find clean water sources.
Food and water quality directly influence our health and parasitic load. Dr. Clark lists various parasites and their food preferences:
- Fasciolopsis buski: Prefers onions and isopropyl alcohol.
- Fasciola hepatica: Prefers wheat (partly digested into gluten and gladin).
- Eurythrema pancreaticum: Prefers limonene (found in lemons, orange oil, etc.) and methanol.
- Clonorchis: Prefers oats.
- Strongyloides: Prefers potatoes.
- Dirofilaria: Prefers milk sugar.
- Ascaris: Prefers quercitin (found in cantaloupe, cheese, cucumbers, etc.).
- Onchocerca: Prefers corn.
- Paragonismus: Prefers lemons and benzene.
- Echinoporyphium recurvatum and Gastrothylax: Prefer cinnamon.
- Echinostoma revolutum: Prefers sorghum and acetaldehyde.
Eliminating these foods for three weeks can starve most parasites. Reintroduce one food weekly afterward. Food oils should also be avoided until the body has processed them, as they nourish Oncoviruses linked to cancer cells and bacteria. Enzymes like pancreatin-lipase can help remove accumulated food oils.
Parasites also contribute to food allergies, which lead to inflammation, further allowing bacteria and viruses to thrive.
