How does one find a legitimate ayahuasca experience in South America without being murdered or robbed?

If any of you have knowledge about this, I have a few months before my pregnant wife reaches her Frieza-style final form and I want to take a little personal trip. If that trip can also involve a legitimate brain reset in the jungle, I think I want to include that, but I don’t want to get scopolamine’d and flayed in the process.
