Clinical research involving human subjects has identified several common foods with measurable effects against intestinal parasites, according to published studies.[2] A major 2025 review published in Frontiers in Parasitology estimated that roughly one billion people globally are infected with intestinal parasites, with approximately 450 million actively ill, pointing to accessible, natural alternatives for a widespread health issue. [2]
A 2007 clinical trial conducted by Obafemi Awolowo University's Department of Paediatrics and Child Health in Nigeria on a batch of 60 children with known existence of intestinal parasites showed the effectiveness of papaya seeds to remove parasites. [1]
The report showed more than 70% reduction in the parasitic existence in the stool samples of those children who consumed a mixture of air-dried papaya seeds and honey, while the other children showed almost no change. [1] The report mentioned, however, that the children receiving the papaya seeds and honey mixture also needed to take a laxative to flush out the parasites. [1]
Clinical Trial Findings and Methodology
The Nigerian study involved 60 children with confirmed intestinal parasites, split into a treatment group and a placebo group. [1] A random group of 30 children was administered a mixture of air-dried papaya seeds and honey (20 ml daily) for seven days; the other 30 children were given a honey-plus-water placebo. [1]
Seven days later, stool sample analysis showed a significant reduction in parasites for the treatment group. [1] Researchers reported that 71% of children who received papaya seeds as treatment cleared their stool of parasites. [3] The protocol required participants to take a laxative to assist in expelling parasites treated by the seed mixture, officials noted in the study. [1]
Air-dried C. papaya seeds are efficacious in treating human intestinal parasites and without significant side effects, according to the published research. [4] The seeds' antiparasitic action works by paralyzing the parasites, preventing them from attaching to the intestinal walls, according to naturopathic sources. [5]
Proposed Usage Protocol and Preparation
A common preparation method involves scooping out a tablespoon of seeds from a freshly cut papa ya and adding them to a good-quality blender. [1] About a cup of sliced papaya is added to the blender, and if desired, a cup of pineapple slices. [1]
The pineapple core is not thrown away as it is the main source of digestive enzymes that also have an anti-parasitic effect, sources indicated. [1] The core also has a lot of fiber and will aid in cleaning the intestinal tract quickly. [1]
The mixture is typically blended with a cup of coconut milk or almond milk. [1] Coconut is also known to be a good parasite remover and would increase the remedy’s effectiveness overall, practitioners said. [1]
Once all ingredients are blended into a smoothie, it is consumed first thing in the morning before eating anything else, according to the protocol. [1] It is followed up with a laxative so that the parasites are flushed out within a few hours. [1]
Dosage, Safety Considerations and Conflicting Research
A starting dose of one or two seeds is recommended to acclimate to the bitter and peppery taste, with a full tablespoon used in the smoothie protocol, according to traditional usage guidelines. [1] The seeds are perfectly safe to eat, but the bitter taste might be overwhelming to start with. [1] Ideally, the smoothie is consumed for three to four days in a row. [1]
Some research indicates that papaya seeds are used to kill parasites in the intestine. [1] However, a study conducted by the team at the National University of Singapore showed that the toxicity levels of papaya seeds required to kill parasites in humans may also damage our intestine and its functions, the research team reported. [1]
Other research, including a study in Mexico on mice, showed antiprotozoal activity from a chloroform-based seed extract, but more research is required in this area, scientists concluded. [1]
Broader Context and Recommendations
Laboratory confirmation of a parasite infection is advised before beginning any cleanse, and consultation with a healthcare provider is recommended, sources stated. [1] Parasites are organisms that live and feed off another living being, leading to a competition between you and the parasite for nutrients, according to health literature. [6]
A growing body of research is dedicated to finding natural remedies for intestinal parasitosis, according to published reports. [7] Other natural substances cited for parasite cleansing include black walnut, wormwood and oregano oil, with specific dosages recommended by herbalists. [1]
Black walnut is known to be anti-parasitic with a recommended dosage of 250 mg thrice a day. [1] Wormwood is recommended at 200 mg thrice a day, and oregano oil at 500 mg four times daily. [1]
Papaya seeds have been largely used in traditional medicine and they may be used in modern medicines in the future to treat such ailments, the source article noted, while emphasizing the need for more research. [1]
Conclusion
The seeds of the papaya fruit have proven antihelmintic and anti-amoebic properties, according to a 2007 clinical trial in Nigeria. [1] Researchers reported that 71% of children who received papaya seeds as treatment cleared their stool of parasites. [3]
The protocol involves a mixture of seeds and honey consumed for seven days alongside a laxative. [1] Common preparation methods involve a smoothie consumed on an empty stomach, though starting with a small dose is recommended due to taste. [1]
While research indicates efficacy, a study from the National University of Singapore noted potential intestinal damage from toxicity levels required to kill parasites. [1] Laboratory confirmation of infection and consultation with a provider are advised before use. [1] Papaya seeds for parasite removal have been largely used in traditional medicine and they may be used in modern medicines in the future to treat such ailments, the source article noted. [1]
