Bitter Leaf is effective against human and livestock parasites in their different stages of development.

Causes and Symptoms of Parasites

Parasites are organisms that live off other organisms, or hosts, to survive. Some parasites don’t noticeably affect their hosts. Others grow, reproduce, or invade organ systems that make their hosts sick, resulting in a parasitic infection.


Parasitic infections can be caused by three types of organisms: 

  • protozoa
  • helminths
  • ectoparasites

Protozoa are single-celled organisms that can live and multiply inside your body. Some infections caused by protozoa include giardiasis. This is a serious infection that you can contract from drinking water infected with Giardia protozoa. 

Helminths are multi-celled organisms that can live in or outside of your body. They’re more commonly known as worms. They include flatworms, tapeworms, thorny-headed worms,and roundworms. 

Ectoparasites are multicelled organisms that live on or feed off your skin. They include some insects and arachnids, such as mosquitos, fleas, ticks, and mites.


The symptoms of parasitic infections vary depending on the organism. For example:

  • Trichomoniasis is a sexually transmitted infection caused by a parasite that often produces no symptoms. In some cases, it may cause itching, redness, irritation, and an unusual discharge in your genital area.
  • Giardiasis may cause diarrhea, gas, upset stomach, greasy stools, and dehydration.
  • Cryptosporidiosis may cause stomach cramps, stomach pain, nausea, vomiting, dehydration, weight loss, and fever.
  • Toxoplasmosis may cause flu-like symptoms, including swollen lymph nodes and muscle aches or pains that can last for over a month.

How Bitter Leaf Helps

Vernonia Amygdalina (Bitter leaf) – a member of the Asteraceae family – a small shrub that grows in tropical Africa

The antiparasitic effect of liquid extract of Bitter Leaf has been studied extensively. It is effective against human and livestock parasitic worms in their different stages of development. Bitter Leaf extract kills parasites by paralyzing and making them unable to feed and consequently, they die off. 

A study comparing the efficacy of 3 commonly prescribed anti-parasitic medications (ivermectin, levamisole, and albendazole) and liquid Bitter Leaf extract, found Bitter Leaf extract to offer higher efficacy against livestock and human parasites.
