Jequirity beans look beautiful, and used for decorating small boxes, baskets, etc., and are made into necklaces, and rosaries which can be used for praying and, hence the plant has given botanical name Abrus (= graceful, delicate) precatorius (= praying). These beautiful red seeds with a black eye are known as Ratti, and were used by goldsmiths in India as weights for weighing silver, and gold due to their uniform shape, size, and weight. Each Ratti weighs about 1.75 grains.
Abrus precatorius is a climber plant, and its roots, leaves, and beans have been used for medicinal purposes in India from very ancient times. The seeds contain abrin, abrine, and abarnin while roots contain precol, abrol, and two alkaloids abraime, and orecasine.
The seeds are used as purgative, emetic, Tonic, and aphrodisiac. The roots are emetic, and alexiteric. The seeds are poisonous, and used in Ayurveda only after proper detoxification. Raw seeds are never used as a medicine. Locally, the leaf juice mixed with oil is applied to painful swellings of the body. The root is also used as a substitute for Licorice.
While all parts of the plant are toxic, the highest concentrations are found in the seeds.
The ingestion of seeds can kill. Abrin present in the seeds leads to disrupted cellular protein synthesis throughout the body. The symptoms are shown after a few hours of ingestion, and include significant vomiting, and diarrhea with resultant hypovolemia, and electrolyte disturbances. There are a few reported cases of abrin causing acute demyelinating encephalitis. There is no known physiological antidote for Jequirity beans. The treatment of Jequirity beans poisoning is essentially symptomatic.

In Ayurveda, the seven drugs which are described, as minor poisons are opium, datura, roots of Nerium odorum (karavirdan), Gloriosa superba, the milky juices of Calotropis gigantea (arka), Euphorbia neriifolia (Snuhi), and Gunja.
All these drugs must not be used as home remedies due to toxic action on the body.
In Ayurvedic text, there are two varieties of Ratti namely, white Gunja, and red seeded Gunja. Both have the same action. Both types of seeds are poisonous, and used in Ayurveda after subjecting to purification process before use.
In Shodhana of Gunja seeds, they are subjected to the svedana in dola yantra with Godugdha or Kanji for 3-6 hours. The Shodhita material is then subjected to washing with hot water, and drying under shade. The boiling of seeds breaks down the toxins present in the seeds. During the Shodhana process, the color of the media changes due to the removal of colored materials from the endosperm of the seeds, and subsequently there is a loss in weight.
Though Gunja is used for medicinal purpose. BUT, it cannot be administered as a single drug, and should be used only in combination.

The seeds have also been found to contain a crystalline nitrogenous compound called abrine, and an amorphous glucosidic substance abraline with a mild bitter taste.
What is Abrin?
Abrin (toxalbumin) is a lectin composed of two polypeptide chains connected by a disulfide bridge. It is a natural poison. Effects of abrin poisoning depend on whether abrin was breathed in, swallowed, or injected.
Abrin kills by getting inside the cells of a person’s body, and preventing the cells from making the proteins. Without the proteins, cells are destroyed. Eventually, this kill.

Abrus seeds contain a toxic lectin, abrin (an albumotoxin), a fatsplitting enzyme, a glucoside (abrussic acid), urease, abarnin, trigonelline, choline, hypaphorine, and steroidal oil that have abortive effects. The toxalbumin, abrin consists of globulin, and a proteose.
Effects of Abrus precatorius on Body organs
- Central Nervous System: Drowsiness, convulsions, hallucinations, and trembling of the hands.
- Gastrointestinal: Severe gastroenteritis with nausea, vomiting, diarrhea, dysphagia, and abdominal cramps
- Haematological: haemagglutination, and haemolysis by a direct effect on red cells.
- Liver: Necrotizing action of the toxin causes the liver damage.
- Renal: Oliguria, and anuria may result. Focal degeneration of the tubular cells.
- Respiratory: Cyanosis secondary to hypotension, and shock.
Abrus precatorius Poisoning
Initial signs, and symptoms of abrin poisoning by breathing in or swallowing are likely to occur within 8 hours of exposure. However, symptoms may also be delayed for 1 to 3 days.
The effects of poisoning with abrin resemble very closely those of the toxalbuminricin, obtained from the seeds of Ricinus communis Linn., and the globulin has been found to be more powerful than the albumose proteose.
Abrin has the property of agglutinating the red blood corpuscles in a manner similar to ricin, and it exerts its action after a period of incubation, regardless of the channel of introduction.
The toxicity of the seeds depends upon the manner in which they are administered. The whole seed may be swallowed with impunity because action the outer covering is so hard that it escapes disintegration, and the toxin is not freed. If chewed before it is swallowed, half a seed may cause poisoning in humans.
Abrin has a fatal dose of 0.1–1 μg/kg in humans, and it is reported that boiling renders the seed harmless.
Since ancient times, Jequirity Bean has been used as a fish poison, arrow poison, and also for criminal purposes of poisoning both humans, and cattle.

How Abrin Poisoning is Treated
As a first-aid measure remove all seed particles from the mouth, induce vomiting, and then seek medical help. Ensure patient’s airway is clear, and that there is adequate ventilation. If the eyes are contaminated, wash eyes with running water for ten minutes.
The treatment of Jequirity beans poisoning is symptomatic as no antidote exists for abrin.
Supportive medical care is given in the hospital to minimize the effects of the poisoning. Supportive measures include parenteral fluids, and electrolytes.
- If exposed, the most important factor is getting the abrin off or out of the body as quickly as possible.
