# Toxic and Hallucinogenic Plants of Southern Chile of Forensic Interest: A Review

## TL;DR

This paper reviews toxic and hallucinogenic plants in southern Chile, highlighting their forensic importance and risks to public health.

## Contribution

The study identifies eight plant species of forensic interest in southern Chile and their toxic compounds.

## Key findings

- Eight plant species with toxic or hallucinogenic properties were identified in southern Chile.
- Most poisoning cases involved unintentional exposure, particularly in children.
- The study emphasizes the lack of regulation and awareness regarding these plants.

## Abstract

Several plants produce toxic and hallucinogenic metabolites, posing risks when misused due to a lack of botanical knowledge. Improper or accidental use of these plants poses a public health risk and has been associated with forensic cases involving poisoning, suicide, or drug-facilitated crimes. This review identified eight species of forensic interest that grow in southern Chile and analyzed their active compounds, mechanisms of toxicity, and documented clinical and legal cases. These selected species included both native and introduced taxa, whose main toxic agents are tropane alkaloids (atropine, scopolamine), piperidine (coniine), taxane pseudoalkaloids, and natural opiates (morphine, codeine). Most reported cases involved unintentional poisoning, mainly in children, highlighting the lack of regulation and awareness. This review revealed the need for improved forensic and clinical documentation of plant-based intoxications in Chile and greater public education regarding the toxicological risks posed by these botanical species.
