Parasites

Wild Oregano Oil

Studies suggest a powerful anti-parasitic action for oregano oil. In one study oregano
oil was administered to 14 adults known to have tested positive for a variety of
parasites including Blastocystis hominis, Entamoeba hartmanni and Endolimax narna.
After 6 weeks of supplementation there was complete disappearance of parasites in
eight cases and reduction in numbers in a further three. Another study examined the
potential of oregano in killing the prolific parasite Giardia lamblia, which infects in
excess of 200 million people every year, is highly contagious and the most common
cause of ‘traveller’s diarrhoea’. Other symptoms include constipation, fatigue and
malnutrition. Oregano was shown to cause significant and terminal damage to the
structure of the parasite and was more effective than a common anti-giardia drug.

Goldenseal
Goldenseal has also demonstrated activity against many parasites, which along with its
antibiotic properties is of great value in helping to prevent or treat ‘traveller’s
diarrhoea’ and many cases of food poisoning.

Pau d’Arco (lapacho, taheebo)

When taken orally, lapachol, the key active component, is thought to eventually be
secreted onto the skin via the sebaceous glands where it acts as a topical barrier,
inactivating microorganisms soon after they contact the skin. In the intestinal tract, it
performs a similar function on the mucous membranes, preventing the penetration of
parasites. The mechanism of action is not well understood, but pau d’arco has been
shown in studies to inhibit a number of parasitic organisms.

Garlic

Garlic exerts broad-spectrum anti-microbial activity against a variety of pathogens
including; viruses, bacteria, fungi e.g. candida species, and parasites. Garlic has a
history of being used to kill parasites and control secondary fungal infections; detoxify
and gently stimulate elimination. It also has antioxidant properties that offer protection
against oxidation caused by parasites' toxins.

Fibre
The fibre content of the diet is a key determinant in the health of the gut. A high fibre
diet promotes probiotic organisms that help to control the level of pathogens in the
gut, including parasites, candida, and pathogenic (bad) bacteria. In the case of an
existing parasitic infection fibre is helpful, in combination with anti-parasitic herbs, in
the removal of parasitic toxins and the restoration of god gut ecology.

Probiotics
Through the fermentation of fibre in the gastrointestinal tract, probiotics are able to
produce various organic acids. These acids have the effect of reducing the pH
(increasing the acidity) of the intestines and as such make the environment undesirable
for resident and non-resident pathogenic bacteria, parasites and yeasts. When used in
combination with antiparasitic herbs, probiotics help to ensure that healthy gut ecology
is restored, thus ensuring better resistance to future infection.
