The Calabar bean, botanically known as Physostigma venenosum, is a highly toxic plant native to West Africa.

Characteristics of Calabar Bean

The Calabar bean is a perennial climbing plant with dark green leaves and striking red and white flowers. It produces large pods that contain hard seeds, which are the toxic part of the plant.

Uses of Calabar Bean

In traditional medicine, the Calabar bean has been used to treat various ailments such as wounds, ulcers, and eye infections. However, due to its high toxicity, it is not recommended for medicinal use.

Toxicity of Calabar Bean

The Calabar bean contains a potent toxin called physostigmine, which acts on the nervous system. Ingesting even a small amount of the bean can lead to symptoms such as nausea, vomiting, convulsions, and even death.

Historical Significance
