"Ouabain" Natural Recordings by Native Speakers
Ouabain is a cardioactive extract from the seeds of the African plant Strophanthus gratus. It is a powerful cardiac glycoside that can increase heart rate and strengthen contractions, but in excessive doses, it can be highly toxic. It is also known as Strophanthin and C-selective glycoside. In medicine, Ouabain is used as a intravenous medicine for treating atrial fibrillation, atrial flutter, and other heart rhythm disorders, but it is relatively rare and usually reserved for severe cases due to its toxicity risks.
Ottonian refers to something or someone related to the Ottonian dynasty, a royal house that ruled the Holy Roman Empire from 911 to 1024. The term is often used to describe the art, architecture, and culture of this period in European history.
