Ayahuasca is a herbal brew that is widespread in Indigenous Upper Amazon and has undergone global expansion in the last decade. As it is taken up in an ever-growing range of ritual or experimental practices questions of authority, authenticity, propriety or safety become acute. This case allows us to interrogate contemporary processes of value-making as radically different and highly stratified values encounter each other, on the brink of a possible pharmaceuticalization of ayahuasca. I argue that ayahuasca is not fully captured by the value logics of capital and examine the ways in which its promissory dimensions, global circulation and entry into practices of biomedical evidence-making position it in an ambiguous space that is nevertheless not entirely outside the logics of capital. The circuits of ayahuasca’s valorization reveal a complex coproduction of value that makes strategic use of various scales, sites and situations. The article examines the promissory horizon of extra-pharmacological value identified as key to understanding the efficacy of psychedelic substances such as ayahuasca. It then attends to the extraction of value from plants before closing with a reflexion on the politics of inclusion in the discussions that frame ayahuasca’s value globally.

Ayahuasca是一种草药酒，在上亚马逊土著地区广泛存在，并且在过去十年中进行了全球扩张。在越来越多的礼仪或实验实践中使用它时，权威性，真实性，礼节性或安全性问题变得非常尖锐。这种情况使我们可以质询当代的价值创造过程，因为几乎完全不同且高度分层的价值彼此相遇，而这可能是阿育吠陀制药化的边缘。我认为ayahuasca并没有完全被资本的价值逻辑所俘获，并研究了它的承兑规模，全球流通和进入生物医学证据制作实践的方式将其定位在一个模棱两可的空间中，但该空间并不完全不在首都。阿亚瓦斯卡（Ahuahuasca）的增值回路揭示了价值的复杂联合生产，可以对各种规模，地点和情况进行战略性利用。本文考察了被认为是理解诸如阿育吠陀等迷幻药物功效的关键的额外药理价值的广阔前景。然后，研究人员在从植物中提取价值之前，先对包含在全球范围内构筑aya树花价值的讨论中的包容性政治进行反思。
