The poisonberry plant belongs to the Solanaceae family, the same family as the potato, and both plants contain the same active component: solanine in their leaves and fruit.

This plant is native to the Americas, where ancient natives called it chichiquelite and used it in popular medicine. The Spanish conquerors introduced it to Europe, where it quickly spread.

Healing Properties and Warning

The green parts of this plant contain a glycoalkaloid: solanine, whose concentration increases with the average temperature of the climate in which the poisonberry grows. Solanine acts powerfully on the nervous system, provoking muscular relaxation, analgesia, and narcosis. It has antispasmodic, analgesic, and sudorific properties when taken internally, but the plant is currently only used externally because of its effects on the nervous system.

On the skin, poisonberry acts as a sedative and emollient substance. It is applied as lotions, compresses, or poultices, to alleviate pruritus (itching) on the vagina or the anus and to sedate the skin itching from scabies, ringworm, herpes, or any other type of rashes.

WARNING! The berries, sweet in taste, are poisonous, though they are not deadly.
