Japanese Yew
Taxus cuspidata
Taxus cuspidata, also known as Japanese yew, is a traditional medicine plant native to East Asia. Its use in traditional medicine has not been extensively documented. Scientific studies have shown that open-grown Taxus cuspidata needles exhibit higher photosynthetic capacity and thicker mesophyll tissue compared to those grown in shaded conditions. Additionally, research indicates potential shifts in the distribution of four Taxus species under future climate scenarios, with expansions towards higher latitudes. In a study involving mice, TCSO (an extract from Taxus cuspidata) reduced liver fibrosis markers and improved antioxidant status without recommending its use for this purpose. MJ-CNPs significantly increased paclitaxel accumulation by 7.3-fold in Taxus cuspidata suspension cells, suggesting potential applications in drug delivery systems. No major safety issues or recorded drug interactions have been noted thus far.
