Wu Banghua expresses the view that although many researchers are applying them selves to analyzing the chemical structure or researching the physiological effects of substances from Taxus species, few are researching their botanical characteristics. However, "inappropriate exploitation of this valuable natural resource has already reduced the worldwide population reserves of Taxus species to very small numbers."
吳榜華認為，許多學者把精力投入紅豆杉屬植物的化學成分分析和生理活性研究，對其生物特性研究卻不多，但是「對此一珍貴資源的不合理利用，致使該屬植物在全球的蘊藏量已寥寥可數。」
