Euphorbia resinifera

Euphorbia resinifera, also known as the resin spurge, is a species of spurge native to Morocco. It is one of the many species of Euphorbia, a large genus of flowering plants in the spurge family (Euphorbiaceae).

Description

The Euphorbia resinifera is a perennial plant that grows as a shrub up to 2 meters high. It has a thick, fleshy stem and branches that are covered in four-sided, spine-tipped ridges. The leaves are small and short-lived, falling off the plant early. The flowers are small and inconspicuous, with no petals or sepals, and are produced in a cluster at the top of the stems.

Distribution and habitat

Euphorbia resinifera is endemic to the Atlas Mountains of Morocco, where it grows on rocky slopes and in dry riverbeds. It is adapted to a Mediterranean climate with hot, dry summers and mild, wet winters.

Uses

The plant is known for its resin, called Euphorbium, which is a powerful irritant and purgative. It has been used in traditional medicine for centuries, and is still used in some herbal remedies today. However, it can be dangerous if ingested or if it comes into contact with the skin or eyes.

Toxicity

Like all members of the Euphorbia genus, Euphorbia resinifera produces a milky sap that is highly toxic. This sap contains diterpenes, a type of compound that can cause severe skin and eye irritation, and can be fatal if ingested.

Conservation status

Euphorbia resinifera is not currently considered to be at risk of extinction, but like many plant species it is threatened by habitat loss due to human activity.
