Helminths – they are worms. Common intestinal worms include hookworms, tapeworms, liver flukes and pinworms.
Protozoa – these organisms are single-celled and can multiply inside the body, causing severe symptoms of infestation.
Fungi – plant-like organisms that may cause symptoms of disease. When their populations grow, they may create an imbalance with the beneficial intestinal microflora, better known as intestinal dysbiosis. The most common fungi causing disease is Candida, which causing many illnesses.
What Are The Causes Of Parasite Infections?
Parasites may enter the body through contaminated water and food. Eating undercooked and uncooked meat, unclean washroom habits, handling animals, contaminated vegetables and fruits and swimming on lakes or ponds.
However, the condition gets worse when a person follows an unhealthy lifestyle. Poor nutrition, stress and long-term medication all contribute to poor immune system and gut health.
A weakened body is a conducive environment for pathogenic microorganisms and parasites and they thrive in it. When a person experiences irregular bowel movements and constipation, undigested foods stay longer in the digestive tract and they ferment.
Fermentation releases sugar that feed parasites and yeast, which affects immune system and gut health. This is the ideal breeding ground for parasites to multiply and cause an infestation.
How Nigella Sativa Works Against Parasites
Nigella sativa seeds have been traditionally used for treating a variety of parasitic diseases.
Schistosomiasis. This condition is also known as bilharzia and snail fever. It is caused by a parasitic flatworms called schistosomes. In vitro testing(2) of black cumin seeds against Schistosoma mansoni, cercariae, miracidia and adult worms denote its potent action against all life stages of this parasite.
It also prevented adult female worms from laying eggs.
The active components of N. sativa induced an oxidative stress on adult worms, manifested by a decrease in the activities of metabolism enzymes and antioxidant enzymes.
Candidiasis. This is a fungal infection caused by Candida albicans, a type of yeast. This disease develops in the mouth, throat or in the vagina. Black cumin seed extract has a strong antifungal action(3)against different strains of Candida.
In an animal study, treatment of N. sativa seeds resulted in a 5-fold reduction of Candida in the kidney, 11-fold in spleen and 8-fold in the liver.
Helminths. N. sativa seeds have exhibited potent action against a number of parasitic worms, including pinworms, Ascaris (roundworm) and Echinococcus (tapeworm).
Amoeba. N. Sativa exhibits a therapeutic effect against Dientamoeba fragilis and other harmful intestinal protozoa.
