Parasites are organisms that live on or inside another organism (the host) and benefit at the host’s expense. They can cause a variety of health problems, ranging from mild discomfort to serious illnesses. 

While modern medicine offers effective treatments for parasitic infections, functional medicine-based treatment suggests other natural ways to support your body’s defense against these unwelcome invaders. This article will explore several natural strategies to bolster your body’s ability to fend off parasites and maintain overall health.

Understanding Parasites

Parasites can be broadly categorized into three types:

  1. Protozoa: Single-celled organisms that can multiply within the host. Examples include Giardia and Plasmodium (the cause of malaria).
  2. Helminths: Multicellular organisms, often referred to as worms, such as tapeworms, roundworms, and flukes.
  3. Ectoparasites: Organisms that live on the surface of the host, such as lice, fleas, and mites.

Parasitic infections can occur through various means, including contaminated water, food, insect bites, and direct contact with infected individuals. Symptoms of parasitic infections vary but may include digestive issues, fatigue, skin problems, and nutrient deficiencies.

Natural Ways to Support Your Body’s Defense Against Parasites

  1. Maintain a Healthy Diet

A balanced diet is crucial for maintaining a strong immune system, which is your primary defense against parasites. Focus on incorporating the following nutrients:

  • Probiotics: Found in yogurt, kefir, sauerkraut, and other fermented foods, probiotics help maintain a healthy gut microbiome, which plays a critical role in defending against parasites.
  • Prebiotics: Foods rich in prebiotics, such as garlic, onions, bananas, and asparagus, feed beneficial gut bacteria, enhancing their ability to protect against parasites.
  • Fiber: High-fiber foods like fruits, vegetables, whole grains, and legumes help maintain digestive health and regular bowel movements, which can expel parasites from the intestines.
  • Antioxidants: Foods rich in antioxidants, such as berries, nuts, and leafy greens, support immune function and reduce inflammation.
  1. Herbal Remedies

Certain herbs have been traditionally used to prevent and treat parasitic infections:

  • Garlic: Garlic has natural antiparasitic properties and can be consumed raw, cooked, or in supplement form. It contains allicin, a compound known to inhibit the growth of parasites.
  • Black Walnut: The hulls of black walnuts have been used to expel intestinal parasites. They contain juglone, a natural compound with antiparasitic effects.
  • Wormwood: Wormwood is a potent herb traditionally used to treat intestinal worms. It can be taken as a tea, tincture, or supplement.
  • Cloves: Cloves contain eugenol, an active compound that has antiparasitic properties. They can be used in cooking or taken as a supplement.
  • Oregano Oil: Oregano oil is rich in carvacrol and thymol, compounds with strong antiparasitic properties. It can be taken as a supplement or used in cooking.
  1. Hydration

Staying well-hydrated is essential for maintaining a healthy digestive system and flushing out toxins, including parasites. Drinking plenty of water supports kidney function and helps eliminate waste products. Aim for at least eight glasses of water a day, and consider increasing your intake if you are physically active or live in a hot climate.

  1. Personal Hygiene

Good personal hygiene practices can significantly reduce the risk of parasitic infections:

  • Handwashing: Wash your hands thoroughly with soap and water before eating, after using the bathroom, and after handling animals.
  • Food Safety: Ensure that food is cooked thoroughly and avoid consuming raw or undercooked meat and fish. Wash fruits and vegetables thoroughly before eating.
  • Clean Water: Drink purified or boiled water, especially when traveling to areas with poor sanitation.
  1. Regular Exercise

Regular physical activity boosts immune function and overall health, making your body more resilient to infections, including those caused by parasites. Aim for at least 30 minutes of moderate exercise most days of the week. Activities such as walking, jogging, swimming, and yoga are excellent for maintaining a healthy body and mind.

  1. Stress Management

Chronic stress can weaken the immune system, making the body more susceptible to infections. Implement stress-reducing techniques such as mindfulness meditation, deep breathing exercises, yoga, and spending time in nature. Ensuring adequate sleep and taking time for hobbies and relaxation can also help manage stress effectively.

  1. Supplementation

In addition to dietary and lifestyle changes, certain parasite cleanse supplements can support your body’s defense against parasites:

  • Probiotics: Taking a probiotic supplement can help maintain a healthy gut microbiome, which is essential for defending against parasites.
  • Vitamin C: An immune-boosting vitamin that can help the body fend off infections. It is available in supplement form and is also found in citrus fruits, strawberries, and bell peppers.
  • Zinc: A mineral that supports immune function. Zinc supplements can enhance your body’s ability to combat infections and are found in foods like pumpkin seeds, lentils, and chickpeas.

One effective supplement to consider is Parasitic Care. This supplement is designed to support the body’s natural defense against parasites. It contains a blend of natural ingredients known for their antiparasitic properties, helping to maintain a healthy balance of gut flora and promote overall digestive health.

When to Seek Medical Attention

While natural remedies and preventive measures can be effective, it’s important to seek medical attention if you experience severe or persistent symptoms of a parasitic infection. Symptoms such as prolonged diarrhea, severe abdominal pain, unexplained weight loss, and persistent fatigue warrant professional evaluation and treatment.


Supporting your body’s defense against parasites involves a multifaceted approach that includes a healthy diet, herbal remedies, proper hydration, good personal hygiene, regular exercise, stress management, and appropriate supplementation. By incorporating these natural strategies into your daily routine, you can strengthen your immune system and reduce the risk of parasitic infections. Always consult with a healthcare professional before starting any new supplement or treatment, especially if you have underlying health conditions or are taking medication. With the right approach, you can maintain a strong and resilient body capable of defending against parasites.
