Question 1

How does Erlangea tomentosa work as an antimalarial?

Accepted Answer

Erlangea tomentosa contains sesquiterpene lactones, which are compounds known to interfere with parasite development. These compounds, along with flavonoids and alkaloids present in the plant, may inhibit Plasmodium parasite growth through oxidative stress mechanisms. The sesquiterpene lactones are particularly noted for their antiprotozoal activity. However, the exact mechanism has not been fully elucidated in clinical studies. Evidence level: C, based on preliminary phytochemical analysis and traditional use rather than controlled trials.

Question 2

Does Imvaho herb interact with antimalarial medications?

Accepted Answer

There are no documented clinical studies examining interactions between Erlangea tomentosa and conventional antimalarial drugs such as artemisinin-based combination therapies. However, given its traditional use for malaria and its active compounds, concurrent use could potentially affect drug metabolism or efficacy. The herb contains alkaloids that may influence liver enzyme activity. Patients taking prescribed antimalarial medications should consult a healthcare provider before adding this herb. Evidence level: C, based on theoretical considerations and traditional use.

Question 3

What is the recommended dosage for Erlangea tomentosa?

Accepted Answer

Traditional Rwandan practice uses 2-4 grams of dried Erlangea tomentosa herb prepared as a tea or decoction for fever and digestive complaints. This dosage is based on ethnobotanical tradition rather than standardized clinical trials. The herb should be taken with food to reduce potential gastrointestinal irritation from its bitter compounds. Duration of use should be limited, and individuals should not exceed recommended amounts without professional guidance. Evidence level: Traditional/C.

Question 4

Is Erlangea tomentosa safe during pregnancy?

Accepted Answer

Erlangea tomentosa is considered unsafe during pregnancy and should be avoided. The herb contains bitter principles and alkaloids that may stimulate uterine contractions or affect fetal development. Traditional contraindications specifically include pregnancy due to potential abortifacient effects. Additionally, the sesquiterpene lactones present in the plant may pose risks to maternal liver function, which is already stressed during pregnancy. Women who are pregnant or planning pregnancy should not use this herb. Evidence level: C, based on traditional knowledge and phytochemical analysis.

Question 5

What is Imvaho herb used for in traditional Rwandan medicine?

Accepted Answer

In Rwandan folk medicine, Erlangea tomentosa, locally known as Imvaho, is traditionally used for treating fever, malaria, and digestive conditions. The herb serves as a bitter digestive tonic to stimulate appetite and improve digestion. Externally, it is applied as a wound healing compress. The plant's antipyretic and antimalarial properties make it a common remedy in regions where access to conventional medicine is limited. Evidence level: C, based on ethnobotanical surveys and traditional use documentation.

Question 6

What are the side effects of Erlangea tomentosa?

Accepted Answer

Erlangea tomentosa may cause gastrointestinal discomfort, including nausea and stomach upset, due to its bitter compounds and tannins. The herb is contraindicated in individuals with liver disease, as sesquiterpene lactones may affect hepatic function. Allergic reactions, including skin irritation from topical application, have been reported in sensitive individuals. The bitter taste may be poorly tolerated by some users. Those with existing digestive conditions should use caution. Evidence level: C, based on traditional use reports and phytochemical properties.
