What Is A Parasite?

A parasite is a living organism whose survival is dependent on another living organism (called a host). It dwells in or on another organism (usually a more advanced organism) and obtains its food and shelter from the organism. They are so dependent on their host that they cannot live without them. These parasites are usually smaller in size than their host; hence, they reproduce quickly and in large amounts increasing in the organism.

So, these parasites often harm the host by causing diseases that disrupt bodily functions. This relationship between the host and the parasite is like that of a bad friendship. A friend benefits from the other, and the other friend is left physically and emotionally exhausted. Some common examples of parasites are; mosquitoes, tapeworm, lice, mites, ticks, etc.

What Essential Oil Kills Parasites & How To Use Them

Parasite resistance is becoming more prevalent, as the conventional usage of only medications in treating parasitic infections is becoming very ineffective. 

However, these medications can work better with essential oils of proven anti-parasitic activity. This is a review of the best ones with useful tips on using them.

1. Oregano Essential Oil 

Oregano essential oil can kill parasites in the body stems, as it contains an intrinsic chemical constituent, “Carvacrol.” This carvacrol in oregano essential oil stops parasites from multiplying in the body. By halting the reproduction of parasites, the body’s immune system can fight it off.

Another quality  that makes this oil suitable for killing parasites is its ability to prevent the parasites from producing a substance called “biofilm.” Parasites use biofilm to shield themselves from destruction in the body. With the biofilm gone, the body’s defense system can fight them off.

Oregano essential oil also reduces the parasite’s ability to stick to red blood cells and to release toxins in the body. The parasite becomes powerless without all its capabilities.


  • Renders the parasites powerless.
  • It rids the body of all accompanying intestinal problems from the parasitic infection.

Hence, this oil literally kills parasites and encourages their expulsion. Thyme essential oil causes the untimely death of the larvae produced by parasites. Thus, this oil is frequently used to deworm and treat hair lice in its larvae and adult forms. 


  • Suitable for deworming.

Myrrh essential oil stops this process by blocking the gene expression leading to the release of the cytokines. This oil also helps the body identify the newly hatched eggs of the parasites poised to start attacking the body. This recognition by the body enables it to mount a defense on the parasites quickly.
