Intestinal Parasites
Intestinal parasites have the ability to enter the body and live off the human host causing a variety of complaints. Tummy pain is a common symptom but is also seen frequently in kids when they feel nervous or stressed. Kids can also develop anemia and have poor growth. The stool may get loose or watery which alternates with times of normal stool or even constipation. Gas and bloating with a sensation of fullness in the belly are also possible signs. The onset of a parasitic infection may present like an acute illness with fever, headache, joint pain and feeling cruddy. However, much of the time, parasites produce little or no symptoms and simply act as a drain on the health of the host. A chronic infestation of parasites can be the root cause of serious illnesses such as chronic fatigue, inflammatory bowel disease, food intolerances, arthritis and autoimmune disease.

It is a popular belief that people living in modern society with proper plumbing and hygiene are not susceptible to parasites. While worms and other parasites are less common in developed countries, those of us living in the US have many opportunities for collecting these tenacious guests. Our pets are a great source as are wading pools, sand boxes, day care centers, mountain streams, raw or rare meat and occasionally even public water systems. It is estimated that one in ten American harbor parasites.
The tape worm is found world wide and can live for years attached to the wall of the small intestine. Humans are the only definitive hosts for tape worms which are collected by eating raw or undercooked meat from cows and pigs who carry these worms. Whipworms and round worms are most commonly found in the Southern United States or through travel to tropical areas. Pinworms are the most common worm infestation in the US. They cause an itchy butt from pinworm eggs laid outside the body. Night scratching with contamination of the hand leads to re-infection of the host. Person-to-person transmission can also occur through handling of contaminated clothes or bed linens. Giardia is a tiny protozoan flagellate and is found in rivers and streams where it can survive for months at very cold temperatures. Giardia may also be passed in day care centers and can sneak into urban water supplies. Cryptosporidium, an intracellular protozoan, has been found worldwide and in the US has been spread in water parks, swimming pools, day care centers and even a major water supply (Milwaukee, Wisconsin1993). While these are some of the more popular infestations found in the US, the list goes on.

One of the biggest challenges is proving that the worms exist. The most common test is called an O & P x3 which looks for ova (eggs) and parasites in a stool sample. X3 means that three random samples are examined. About 90% of stool samples are negative. While some of this stems from improperly ordered tests, a good percentage is due to the difficulty of collecting a good sample. Eggs or parasites are estimated to be found in only 40% of O&P x3 in individuals who have parasites. Alternative labs such as Doctor’s Data may be more successful in processing a sample and will provide a culture and sensitivity for herbal treatments. When symptoms exist and a probable source for infection is identified, treatment without proof may be indicated.

An herbal treatment, preceded by an anti-worm diet and followed by a purgative, can be very effective in treating a parasitic infection. Often the treatment is repeated, sometimes several times, to make sure all stages from the egg to the adult parasite are eradicated. Pinworms may be treated with garlic, carrots and pineapple mayweed. Quassia has been used as an enema to treat the infestation of pinworms directly as the worms live at the end of the bowel. This herb is also active against Giardia. Tansey has been used and is effective against pinworms but is a highly toxic herb and is best avoided. For tape worms, the most effective treatment is male fern. However, this herb can be very toxic so must be used with the support of your doctor. A synthetic formulation of the male fern is a drug called Niclosamide which is much safer than the herb and reported to be very effective. Pumpkin seed in large doses is very safe if less effective. Wormwood tea or capsules taken morning and night for three days followed by a purgative can be a successful and low toxic approach to tapeworms and Giardia and may even be effective against the tenacious roundworm. Goldenseal or herbs containing berberine will act against Giardia. Black walnut is also an effective anti-parasitic herb. Roundworms resistant to wormwood are best eradicated with Chenopodium. The oil of this herb has traditionally been used but is very toxic. Alternately the liquid extract can safely be taken. A couple of days prior to a treatment, we can eat things which are unpleasant for worms such as salty foods, pineapple, turmeric, cloves, garlic and onions, pumpkin seeds and pickles.


When to call a doctor:
·
If you suspect a parasite infection and want help diagnosing
·
You know you have parasites and you want help with your herbal prescription. There are two concerns when dosing herbs to kill worms. One is that you need a high enough dose to kill the parasite. The other is that you have a low enough dose to avoid harm to the patient. When treating parasites, the effective dose is often not far from a harmful dose.
·
You are considering using a toxic herb.
·
You are considering using a drug which requires a prescription.
