Parasites are organisms that live on or within the blood, tissues, or intestines of a host, and they can cause various diseases and infections. While there are many types of parasites, intestinal parasites are the most common, and they are typically transmitted through contaminated food or water. To prevent parasitic infections, it is essential to have access to safe drinking water, maintain proper personal hygiene, and practice good sanitation behaviours. Although dietary changes and natural parasite cleanses may help improve overall health and boost the immune system, there is limited research on the effectiveness of these cleanses in treating parasitic infections. Instead, it is recommended to consult a healthcare professional and seek proper medical treatment, such as antiparasitic medications, if a parasitic infection is suspected.

What You'll Learn
Parasites are transmitted through contaminated water
In developing countries, water purification at the household level is an important aspect of hygiene. Boiling water is believed to be the best method of obtaining water that is free from biological contamination. To kill or inactivate Cryptosporidium and Giardia, water should be kept at a rolling boil for one minute (three minutes at elevations above 6500 feet). Water filters can also be used to purify small volumes of water, but they must be regularly cleaned and maintained. However, not all home water filters can remove parasitic protozoa.
In industrialized countries, the use of treated wastewater for domestic, industrial, and agricultural purposes is common. However, wastewater treatment plants can become a source of pollution for drainage areas if the wastewater is not properly treated before being discharged. Cysts and oocysts of protozoa can be found in waste, surface, and groundwater sources, as well as in drinking water samples, even after treatment with conventional methods. These cysts and oocysts are small enough to penetrate water treatment systems and may cause outbreaks and epidemics after consumption of purified drinking water.
To prevent parasitic infections, it is important to have access to safe drinking water, maintain good personal hygiene, and practice proper sanitation behaviors. Regularly testing drinking water for bacteria and other common contaminants can help identify if a water system is susceptible to surface contamination. If parasitic infection is suspected, it is important to see a healthcare provider for diagnosis and treatment, which may include antiparasitic medication, vitamins, and dietary changes.

Water purification methods to kill parasites
Water purification is essential to ensure access to safe drinking water and prevent parasitic infections. Parasites can enter water sources through various pathways, including wastewater discharge, agricultural runoff, and human or animal fecal contamination. Here are some water purification methods to kill or remove parasites:
Boiling
Boiling water is an effective way to kill parasites, bacteria, and viruses. It is a simple and inexpensive method that has been routinely practiced in many developing countries due to a lack of confidence in the safety of the water supply. To effectively kill parasites such as Cryptosporidium and Giardia, water should be brought to a rolling boil for at least one minute. At higher elevations above 6,500 feet, it is recommended to boil the water for three minutes. While boiling is effective, it can be time-consuming and may not be practical for families with high water consumption.
Filtration
Water filtration is another method to remove parasites from drinking water. However, not all filters are created equal. Most portable water filters can remove parasites, but they may not effectively eliminate viruses or bacteria. To ensure the removal of parasites, look for filters with an absolute pore size of 0.3 microns or smaller. Reverse osmosis filters are a type of water filtration system that can effectively remove parasites, bacteria, and viruses, as well as salt from the water.
Chlorination
Chlorination is commonly used in municipal water treatment systems to disinfect water and kill bacteria. While chlorine is effective against bacteria and viruses, it may not be sufficient to kill all types of parasites. Chlorine dioxide tablets, for example, can kill the parasite Giardia and reduce Cryptosporidium, but filtration is still recommended as a complementary treatment.
Wastewater Treatment
Proper wastewater treatment is crucial to prevent the contamination of water sources with parasitic protozoa. In developing countries, the use of treated wastewater for various purposes is common, but if the wastewater is not properly treated, it can become a source of pollution for nearby water bodies. Therefore, effective wastewater treatment plants are essential to prevent the spread of parasitic infections.
Sanitation and Hygiene
Improving sanitation and hygiene practices is another important aspect of preventing parasitic infections. This includes proper disposal of waste, personal hygiene, and ensuring that drinking water sources are not contaminated. These measures work in conjunction with water purification methods to provide multiple barriers against parasitic infections.

Parasite cleanse diets
The specifics of parasite cleanse diets vary, but they often involve a combination of herbal supplements, such as anise, clove, grapeseed, wormwood, and goldenseal, alongside dietary changes. Some natural health practitioners recommend parasite cleanse diets that include herbs and supplements, but there is very limited research supporting these claims.
While certain dietary changes can improve overall health and boost the immune system, they should not be the sole treatment for parasites. There is no evidence that herbal supplements or other ingredients can effectively treat parasitic infections. Trying to self-treat a suspected parasite with supplements and spices can be harmful and is unlikely to get rid of a parasite.
If you suspect you have a parasite, it is important to see a healthcare provider for a diagnosis and effective medical treatment. Prescription antiparasitic medication is typically required to treat parasitic infections. Additionally, maintaining proper hygiene, sanitation, and wastewater treatment practices are crucial to prevent the transmission of parasites through contaminated water or food.

Symptoms of parasitic infections
A water diet, or any other detox diet, will not kill parasites. Parasites are organisms that live in or on another organism and can spread infections. Parasitic infections occur when parasites grow, reproduce, or invade organ systems, making their hosts ill.
The symptoms of parasitic infections vary depending on the parasite. Some common symptoms include:
- Abdominal pain
- Bloating
- Vomiting
- Diarrhea
- Constipation
- Gas
- Nausea
- Fatigue
- Weight loss
- Mild swelling at the infection site
- Low fever
- Body aches and pains
- Skin rash
- Headache
- Irregular heartbeat
- Congestive heart failure
- Swollen esophagus
If you suspect you have a parasite, it is important to see a healthcare provider for a diagnosis and effective medical treatment.

Treatment for parasitic infections
A parasite is an organism that lives in or on another organism, called the host, and benefits from the host at the host's expense. Parasites can be microscopic or large enough to be seen with the naked eye, and they survive by feeding off their host. Parasites usually enter the body through the mouth or skin.
Parasitic infections occur when parasites grow, reproduce, or invade organ systems, causing illness in their hosts. Protozoa and worms (helminths) are the two main types of parasites. Protozoa are single-celled organisms that multiply inside people, while worms consist of many cells and have internal organs.
The treatment for parasitic infections depends on the type of infection and its severity. In some cases, parasitic infections may clear up on their own without medication. However, most people will require prescription antiparasitic medication to treat the infection.
Antiparasitic Medication
Antiparasitic drugs are a group of medications used to treat infections caused by parasites, including protozoa, helminths, and ectoparasites. These medications work by paralyzing the parasites and stopping them from growing or reproducing. Some common antiparasitic drugs include:
- Benznidazole and nifurtimox for Chagas disease
- Metronidazole (Flagyl) for Giardia infections
- Praziquantel (Biltricide) for tapeworms
- Medendazole (Vermox) for roundworms
Other Treatments
In addition to antiparasitic medication, other treatments may be necessary depending on the specific parasite and the symptoms it causes. For example, vitamins may be recommended to help restore nutrient levels affected by the parasite. In some cases, surgery may be required to remove cysts or worms causing bowel obstructions.
Preventing Parasitic Infections
To prevent parasitic infections, it is important to practice good hygiene and sanitation, especially when traveling to areas where food, water, and sanitation may be contaminated. Drinking water purification is essential to ensure access to safe drinking water. Boiling water for one minute at sea level (three minutes at elevations above 6500 feet) can help kill parasitic protozoa such as Cryptosporidium and Giardia.
Dietary Changes
While dietary changes alone are not sufficient to treat a parasitic infection, they can be a helpful complement to medical treatment. A healthy diet that includes high-fiber foods and probiotic foods can improve gut health and help fight off parasitic infections. Eating a balanced diet, limiting added sugars and ultra-processed foods, and incorporating certain foods such as garlic, ginger, and vitamin A may also be beneficial.
It is important to note that there is limited research on the effectiveness of natural parasite cleanses, and they may bring health risks. Always consult a healthcare professional before trying any parasite cleanse or supplement.

Frequently asked questions
Parasites are organisms that live on or within the blood, tissues, or intestines of a host, getting their food from the host and negatively impacting their health and well-being.
Parasites can be contracted by consuming contaminated water or food, especially when travelling abroad. Intestinal parasites are often contracted by eating or drinking something that has been contaminated with faeces from an infected individual. External parasites, such as ticks, lice, or mites, are known as ectoparasites.
Symptoms of a parasite infection include abdominal pain, bloating, vomiting, diarrhoea, and unexplained weight loss. However, it is important to note that just because someone experiences these symptoms does not mean they have a parasitic infection.
If you suspect you have a parasite infection, it is best to consult a doctor. They can perform tests to check for parasites, such as stool tests, endoscopy, blood tests, and imaging tests. If parasites are found, they will prescribe medication to treat the infection. While some natural ingredients may help treat parasites, there is limited research on the effectiveness of parasite cleanses and detox diets, and they can bring significant health risks.
There is no evidence that a water diet will kill parasites. In fact, drinking water can be a source of parasitic infection if it is not properly purified or treated. To kill parasites in drinking water, it is recommended to boil the water for one minute at sea level and three minutes at elevations above 6500 feet.
