jequirity

Jequirity is a common name for Abrus precatorius, a slender, woody climber in the legume family, also known as rosary pea or crab's eye. Native to tropical regions of Asia and Africa, it has been widely introduced elsewhere as an ornamental plant. The plant bears pinnate leaves and small white flowers, followed by seeds that are bright red with a glossy black spot at one end.

Historically, the seeds have been used to make jewelry and rosaries and as decorative beads. They are extremely toxic when chewed or swallowed due to the presence of abrin, a highly potent protein toxin. Intact seeds are not generally dangerous if not ingested, but even a single chewed seed can be fatal. Because of this risk, handling the seeds requires care and they should be kept away from children and pets.

Abrin inhibits protein synthesis by inactivating ribosomes, leading to cell death. There is no antidote; treatment is supportive care. Poisoning can affect multiple organ systems and may be fatal, depending on the dose.

Ecologically, Abrus precatorius can be invasive or naturalized in suitable tropical climates. The plant's attractiveness belies its danger, and many regions regulate or discourage cultivation where children or livestock may encounter the seeds. The term jequirity is sometimes used generally to refer to the seeds themselves rather than the plant.
