Description:
Rosary pea is a twining woody vine with slender stems. The flowers resemble pea flowers and form dense clusters of pale reddish purple to lavender pink flowers. The fruit is a flat broad pod covered with tiny hairs. The pod may contain 4-8 seeds that are pea-sized, ovoid, and bright red with a black spot at one end. The seeds are sometimes used to make necklaces.
Toxic Part: The entire plant is toxic. However intoxication usually occurs when the seed coat is broken (for example when the seed is chewed or broken). The seeds retain their toxicity for many years.
Toxin: The toxin is abrin, a glycoprotein lectin.
Symptoms: In humans, symptoms can develop several hours to several days following ingestion. These include nausea, vomiting, diarrhea, abdominal cramps. There may be loss of intestinal function.
Treatment: Vomiting should be induced immediately. The symptoms are treated by replacing fluids and electrolytes.
