Artemisia Herb Fights Malaria and Dengue Fever

Artemnisia (wormwood) treats dengue and malaria

Research is increasingly showing that the herb sometimes called Wormwood (Artemisia annua) inhibits malaria parasites. Malaria is one of the most lethal mosquito-borne infections around the world.

Malaria infects over 200 million people a year worldwide and kills somewhere around a million people a year.

Artemisia kills parasites

In the most recent study, botany researchers from the University of Delhi found that an extract derived from the leaf of the Artemisia annua plant kills the parasites associated with the malaria and dengue fever infections.

The researchers found this by applying the Artemisia extract against the parasite larvae derived from the mosquito species Anopheles stephensi-female (malaria) as well as larvae derived from Aedes aegypti (which transmits dengue fever).

The extract showed “strong larvicidal activity against both of these vectors,” according to the researchers. This means the Artemisia killed the parasites.

The researchers then separated the extract into fractions, and found that three fractions also had significant killing activity against both types of larvae. The researchers found that the active compound from these purified fractions were Artemisinin, Arteannuin B and Artemisinic acid.

Other research confirms these findings

This study confirms previous research that has found the Artemisia plant significantly treats malaria.

A 2011 study from the Guangzhou University of Chinese Medicine conducted a clinical trial with 220 malaria patients that used three different Artemisia extract formulations – Artemisinin-piperaquine, dihydroartemisinin-piperaquine phosphate and artemether-lumefantrine.

They found that parasites were cleared from the patients for all three formulations in an average of 65 to 67 hours.

In another study, from Tanzania, researchers tested Artemisia tea with malaria patients. At seven days, the Artemisia tea resulted in a 70% cure rate. A 2004 German study found similar results – a 74% curate rate after seven days.

It should be noted that this 2004 study found Quinine had a 91% cure rate at seven days. The researchers suggested that Quinine would be the preferable medication.

Quinine resistance

But sometimes Quinine is not available, and some malaria species (five different protozoa species are responsible for malaria) are resistant to Quinine.

Quinine is a natural product as well. Quinine is derived from the bark of the Cinchona (Cinchona officinalis) tree. This has been used for many conditions for centuries in South America. Today the drug chloroquine is most used for malaria, though natural quinine is still also in use.

In addition, it should be mentioned that the clinical studies noted above utilized Artemisia tea rather than ingesting the whole herb plant.

Indeed, research has established that Artemisia’s active constituents are better assimilated by the digestive tract when the whole leaves or whole plant are eaten.

Researchers from Massachusetts’ Worcester Polytechnic Institute used a laboratory model that duplicated gastric digestion, and measured the digestive availability of Artemisia dried leaves. They found there was a significant digestive absorption opportunity for Artemisinin and associated flavonoids when the dried leaves were consumed in the model.

The researchers also tested powdered dried leaves either encapsulated or tableted, and found that the encapsulated versions only allowed for 50% of the availability of the Artemisinin. Testing of the tablets found these had similar availability as the dried leaves.

The researchers concluded that:

“This study provides evidence showing how both artemisinin and flavonoids are affected by digestion and dietary components for an orally consumed plant delivered therapeutic and that artemisinin delivered via dried leaves would likely be more bioavailable if provided as a tablet instead of a capsule.”

Artemisia grows in temperate climates, often in regions that have dengue fever outbreaks. The Wormwood name is also applied to other Artemisia species as well.
