Question 1

How does Erythrophleum suaveolens work in the body?

Accepted Answer

Erythrophleum suaveolens contains alkaloids including cassaine and erythrophleine that act similarly to cardiac glycosides. These compounds inhibit sodium-potassium ATPase, increasing intracellular calcium in cardiac cells and producing a strong stimulant effect on the heart. This mechanism is similar to digoxin but with a much narrower therapeutic window, making the plant extremely dangerous even in small amounts. Evidence level: C.

Question 2

What are the drug interactions of Erythrophleum suaveolens?

Accepted Answer

Erythrophleum suaveolens has potentially lethal interactions with all cardiac medications, particularly digoxin, beta-blockers, calcium channel blockers, and antiarrhythmic drugs. The cardiac glycoside-like alkaloids can cause additive toxicity when combined with other heart medications. Concurrent use with diuretics may increase toxicity through electrolyte imbalances. Due to its extreme toxicity, this herb should never be combined with any medication. Evidence level: C.

Question 3

What is a safe dosage of Erythrophleum suaveolens?

Accepted Answer

There is no safe self-medication dosage for Erythrophleum suaveolens. The plant is highly toxic with lethal doses occurring in very small amounts. Historically, trained practitioners used minute controlled doses, but the margin between therapeutic and lethal doses is extremely narrow. Modern use is restricted to laboratory research settings only. This herb should never be used for self-treatment. Evidence level: C.

Question 4

Is Erythrophleum suaveolens safe during pregnancy?

Accepted Answer

Erythrophleum suaveolens is absolutely unsafe during pregnancy and breastfeeding. The toxic alkaloids, including cassaine and erythrophleine, can cross the placenta and cause fetal harm or death. The cardiac effects could lead to maternal cardiac arrest, fatal for both mother and fetus. There is no traditional or modern evidence supporting any safe use during pregnancy. This herb must be completely avoided. Evidence level: C.

Question 5

What was Erythrophleum suaveolens used for historically?

Accepted Answer

Erythrophleum suaveolens was historically used in West African tribal societies as an ordeal poison to determine guilt or innocence in legal disputes. The accused would consume the bark; survival indicated innocence while death proved guilt. It was also used as an arrow poison for hunting and, in carefully controlled doses by skilled practitioners, as a cardiac stimulant. Evidence level: Traditional.
