Bitter-ash
Euonymus atropurpureus
Euonymus atropurpureus, commonly known as purple spindle or Japanese spindle, is a plant traditionally used in East Asian medicine. However, specific traditional uses for this species are not well-documented. Scientific studies have shown that the spring phenophases of shrubs occur approximately 3 weeks earlier than those of trees, with native shrubs exhibiting a 6-day advantage in full-leaf unfolding. Additionally, research has identified 22 fungal species from diseased Euonymus japonicus specimens in Beijing and noted the extinction of 51 plant species since European settlement in North America, but these findings do not directly pertain to E. atropurpureus. Safety concerns are minimal; no major issues have been recorded. There is also no evidence of drug interactions associated with this plant.

Was die Wissenschaft sagt
- Alle drei Frühjahrsphänophasen traten bei Sträuchern um 3 Wochen früher auf als bei Bäumen, mit indigenen Sträuchern eine Vorsprung von 6 Tagen im vollständigen Blattausbreiten zeigend.
- Die Studie zeigt an, dass 51 Arten und 14 infraspezifische Taxa von Gefäßpflanzen in Nordamerika seit der europäischen Besiedlung ausgestorben sind.
- The study found no relationship between anatomical xylem characteristics and hydraulic conductivity between native and non-native woody species.
- Die Studie erkannte 22 Pilzarten an kranken Euonymus-japonicus-Exemplaren in Peking und drei neue Pathogene für diese Pflanze.
