Parasites

  • Berberine

    Berberine is derived from several plants, including barberry, Oregon grape, goldenseal, and goldthread. Studies have shown that berberine kills amoebae and can be used successfully to treat giardia infections.

    Dose:

    Consult a qualified healthcare practitioner
    Berberine
    ×

    Berberine is derived from several plants, including barberry, Oregon grape, goldenseal, and goldthread (Coptis chinensis). Preliminary trials have shown that berberine can be used successfully to treat giardia infections.1,2 In addition, test tube studies show that berberine kills amoebae, although it is not known whether this effect occurs in humans.3 The amount required is approximately 200 mg three times per day for an adult—a level high enough to potentially cause side effects. Therefore, berberine should not be used without consulting a healthcare provider.

  • Ipecac

    Emetine and other alkaloids in ipecac kill several types of parasites, including amoeba, pinworms, and tapeworms.

    Dose:

    Consult a qualified healthcare practitioner
    Ipecac
    ×

    Emetine and other alkaloids in ipecac kill several types of parasites, including amoeba, pinworms, and tapeworms.4,5 Generally the amounts of ipecac needed to produce these effects in people are high and can lead to severe side effects. Emetine or its somewhat safer form, dihydroemetine, are reserved for rare cases of people infected with amoebae who are not cured by using anti-amoeba drugs.6 Because of the danger involved, ipecac and emetine should never be used without first consulting a physician.

  • Papaya Seed

    Seeds of the papaya fruit have been used in folk medicine to treat intestinal parasites. In one trial, supplementation eradicated intestinal parasites in 71 to 100% of children.

    Dose:

    Single administration of 4 grams
    Papaya Seed
    ×
    Seeds of the papaya fruit (Carica papaya) have been used in folk medicine to treat intestinal parasites. In a preliminary trial conducted in Nigeria, treatment with papaya seeds eradicated intestinal parasites in 71 to 100% of children, depending on the parasite being treated. Parasites that were successfully eradicated were A. lumbricoides, E. histolytica, N. americanus, S. stercoralis, T. trichiura, G. lamblia, and T. saginata. Treatment consisted of a single administration of 20 ml of an elixir containing 4 grams of air-dried and blended papaya seeds.7
  • Propolis

    Propolis, a resinous substance collected by bees from trees, has antimicrobial properties that may help protect against parasitic infections in the gastrointestinal tract.

    Dose:

    Consult a qualified healthcare practitioner
    Propolis
    ×

    Propolis is a resinous substance collected by bees from the leaf buds and bark of trees, especially poplar and conifer trees. The antimicrobial properties of propolis may help protect against parasitic infections in the gastrointestinal tract. One preliminary trial of propolis extract for children and adults with giardiasis showed a 52% rate of successful parasite elimination in children and a 60% elimination rate in adults (amount not stated).8 These results are not as impressive as those achieved with conventional drugs for giardiasis, though, so propolis should not be used as the sole therapy for parasites without first consulting a physician about available medical treatment.

  • Anise

    Anise may have modest antiparasitic actions and has been recommended by some practitioners as a treatment for mild intestinal parasite infections.

    Several other herbs are traditionally used for treatment of parasites, including male fern (Dryopteris filix mas) root, tansy (Tanacetum vulgare) leaf, wormwood, sweet Annie, black walnut (Juglans nigra) fruit, and cloves (Syzygium aromaticum). Numerous case reports and preliminary studies from the late 1800s and early 1900s have suggested some of these herbs can be helpful for some parasitic infections.13

  • Chaparral

    Chaparral has been historically used in some cultures as a way to detoxify and eliminate parasites.

    In some cultures, it was customary to bathe in chaparral once per year to eliminate skin parasites and to detoxify; however, there is no modern research demonstrating the effectiveness of this use of chaparral.

    Curled Mint
    ×

    Curled mint (Mentha crispa) leaf, a close relative of peppermint, has been shown in a preliminary trial to help relieve the symptoms of giardia and amoeba infections in children and adults, as well as to eliminate these parasites in many cases.15 This study used a tincture of curled mint in the amount of 2 ml three times per day for five days, or 1 ml three times per day for five days for children. Given their close relationship, peppermint could probably be substituted for curled mint when curled mint is unavailable.

  • Garlic

    Garlic has been shown to kill parasites, including amoeba and hookworm, in test tubes and in animals. Other studies support the use of garlic to treat roundworm, pinworm, and hookworm.

    Garlic has been demonstrated to kill parasites, including amoeba16 and hookworm,17 in test tubes and in animals. Older studies in humans support the use of garlic to treat roundworm, pinworm, and hookworm.18 However, due to a lack of clinical trials, the amount of garlic needed to treat intestinal parasites in humans is not known.

    Pumpkin seeds (Cucurbita pepo) have purported effects against tapeworms. Given their safety, they are often recommended as an addition to other, more reliable therapies. In Germany, 200–400 grams are commonly ground and taken with milk and honey, followed by castor oil two hours later.29 Tapeworms can cause severe illness and should be treated only with medical supervision. In China, pumpkin seeds have been shown to effectively treat acute schistosomiasis, a severe parasitic disease occurring primarily in Asia and Africa that is transmitted by snails.30 The assistance of a physician is required to help diagnose and treat any suspected intestinal parasite infection.
