民族药理学的相关性杜鹃花科植物，特别是杜鹃花属植物经常被报道含有grayanotoxins。蜂蜜等植物产品和由这些植物制成的草药偶尔含有grayanotoxins，反过来可能导致中毒。杜鹃花中毒的利益和风险之间的平衡值得关注。本研究探讨了民族植物学知识的人在云南，中国方面的消费杜鹃花，并给予特别关注他们的评估的利益-风险balances.Materials和methodsAn民族植物学调查进行了跨越14个县级地方市场在云南省北部和中部，在此期间，共82个摊位出售杜鹃花进行了访问和204人进行了采访。收集者的指导下，获得的标本，并详细记录当地的做法和知识，使用半结构化的采访和参与observations.ResultsThe消费的花冠ofRhododendron decorumFranch。花（RDf）或厚枝杜鹃（Rhododendron pachypodum Balf.）F. & W. W. SM.花卉作为时令美食在滇西北和滇东北地区有着悠久的传统，而在滇中地区则更为普遍，且对各品种的解毒或适口过程的认识具有高度的一致性。食用菊花的主要原因是保健（多为清热）、野生采集、传统和风味好。所有的消费者都表示，该物种的花冠是无毒的，而67.4%的消费者声称，从RDf的花冠是有毒的。我们比较了这两个物种，并分析了他们的工艺强度，中毒案件和注意事项，市场贸易形式和现有的毒性研究，同意以及一致的RDf的花冠值得更多的毒性关注than RPf.ConclusionOur研究提供了一个窗口，看看的方式，超越蜂蜜和草药，Rhododendronspecies影响人类的福祉。当地文化可以证明吃杜鹃花是合理的，同时，已经开发了一系列技能来避免吃它们的副作用，因此这项研究也提供了一个很好的案例，通过评估利益和副作用之间的权衡来回答关于吃任何植物产品的合理性的更普遍的问题。
Ethnopharmacological relevancePlants from the family Ericaceae, and in particular those in the genusRhododendronare frequently reported to contain grayanotoxins. Plant products such as honey and herbal medicines made from these plants occasionally contain grayanotoxins, and in turn may lead to intoxication. The balance between the benefits and risk of poisoning fromRhododendronsis of concerns. This study explores the ethnobotanical knowledge of the people in Yunnan, China as regards the consumption ofRhododendronflowers, and gives special focus to their assessment of the benefit-risk balance.Materials and methodsAn ethnobotanical survey was conducted across 14 county-level local markets in north and central Yunnan province, during which a total of 82 stalls sellingRhododendronflowers were visited and 204 people were interviewed. Voucher specimens were obtained under the guidance of collectors, and details about local practices and knowledge were recorded using semi-structured interviews and participatory observations.ResultsThe consumption of the corollas ofRhododendron decorumFranch. Flowers (RDf) orRhododendron pachypodumBalf. f. & W.W. Sm. Flowers (RPf) as a seasonal delicacy is a long-standing tradition in the study area.RDf are widely consumed in northwest and northeast Yunnan, whileRPf are more prevalent in the central regions of Yunnan, and there is a high consistency in the knowledge of the process for detoxification or palatability for each species. The main reasons for eating the flowers were listed as health benefits (mostly clear heat), wild collected, tradition and good flavor. AllRPf consumers stated that the corolla from this species is not toxic, while 67.4% of theRDf consumers claim that the corolla fromRDf is toxic. We compared the two species and analyzed their process intensities, poisoning cases and cautions, market trade forms and existing toxicity studies, which agreed well and consistently that the corolla ofRDf deserve more toxicity attention thanRPf.ConclusionOur study provides a window to look into the ways, beyond honey and herbal medicine, by whichRhododendronspecies have influenced human wellbeing. The local culture can justify eatingRhododendronflowers, and meanwhile, has developed a series of skills to avoid the side effects of eating them, and therefore the study also provides a good case to answer more general questions about the rationality of eating any plant products by assessing the trade-off between benefits and side effects.
