Codex Pharmakon Universalis records how substances were described and used across historical medical traditions. It is a work of history and education.
Nothing here is medical advice, a diagnosis or a recommendation to take, prepare or stop taking anything. Many substances in these traditions are toxic, interact with medicines or are controlled in some countries.
Speak to a qualified healthcare professional before acting on anything you read here. If you think someone has been poisoned, contact emergency services.
Every entry is one verified substance, deduplicated across nine historical medical traditions, from the Ebers Papyrus of about 1550 BCE to the Northwest Amazon. Choose a substance from the list, or search.
The gold number beside each name is how many traditions attest it. A diamond marks a written entry.
