Traditional Amazonian medicine has become a global phenomenon. Nowadays, rituals are organized not only in South America, but also in European countries, North America and Australia. Due to legal regulations in the Czech Republic, the users of traditional Amazonian medicine create a specific subculture. In order to investigate it, I did a literature review and conducted 46 semi-structured interviews with participants of the rituals during year-long field work done since November 2015. The research focused on the therapeutic potential of traditional Amazonian medicine. The results demonstrate that it can be applied in the treatment of various lifestyle diseases.
