Biological Activities
Stangeria eriopus is a cycad species found in South Africa that holds significant medicinal and magical importance among several ethnic groups. The plant's underground caudex is used extensively in traditional preparations, most notably as a potent emetic. Chemical analysis suggests that the efficacy of this emetic effect may be attributed to an unusually high content of sodium sulphate within the caudex material. While the plant contains various amino acids and phytosterols, it also possesses toxins such as cycasin and macrozamin. Due to the high demand for these medicinal uses, continued harvesting now poses a serious threat to remaining plant populations.
Compounds
Stangeria eriopus possesses a complex chemical profile within its underground caudex that includes several notable compounds. Analysis of the plant reveals the presence of the non-protein amino acid pyroglutamic acid. Furthermore, the cycad contains specific phytosterols, namely stigmasterol and sitosterol, which exist in a distinct ratio. The chemical makeup also includes significant toxic components such as cycasin. This toxin is found to be accompanied by the closely related substance macrozamin.
Conditions
Stangeria eriopus serves multiple medicinal purposes within traditional South African practices. The underground caudex of this cycad is utilized by various ethnic groups as an emetic. This emetic effect may be attributed to the unusually high content of sodium sulphate found within the plant material. Additionally, the species has been identified as an active plant in the treatment of high blood pressure. Specifically, it was found to inhibit angiotensin converting enzyme during screenings of Zulu medicinal plants.
Preparations
Stangeria eriopus is utilized in various ways, including being prepared as aqueous extracts for medicinal screening. The plant is also prepared as ethanolic extracts, which are tested for their potential to inhibit angiotensin converting enzyme. Beyond these chemical preparations, the species is used as an emetic, a function possibly linked to its high sodium sulphate content. Additionally, the underground caudex of Stangeria eriopus is frequently prepared as an ingredient in magical potions. These diverse uses highlight the plant's significant role in both traditional medicinal and spiritual practices in South Africa.
