Medicinal Uses, Benefits, Dosage And Properties Of “Abrus Precatorius (Rosary Pea)” Commonly Known As “Saga” In The Philippines

Saga is a slender, twining, branched, annual vine. It is sparingly hairy or nearly smooth. Leaves are alternate, and compounded into pinnate arrangement of about 20 to 40 leaflets to each leaf; each leaflet oblong, rather thin. Inflorescence is an axillary raceme, shorter than the leaves with numerous crowded flowers. Flowers are pink to purple or salmon in color. Calyx teeth short and standard petal ovate, the wings narrow, and the keel arched. Stamens are 9, the filaments of which united into a tube with a slit above. Ovary with many ovules with a short style. Fruits are pods, oblong and turgid. Seeds are 3 to 5 in a pod, round and shiny, half-red and half-black. Color of seeds is the the most recognizable characteristic of this species.

– Study yielded Abrin A from the seeds, and similar to Abrin protein and abrin C, is toxic to cell-free protein synthesis.
– The toxic principle chemically and pharmacologically resembles ricin.
– Active principle is the toxalbumin, abrin. Abrin consists of two fractions, a globulin and an albumose, two proteids.
– An analysis of the seed isolated two products: one, nitrogen-containing, and the other, a glucoside – abrin and abralin.
– Seeds contain the principle compound abrine, together with abraline, abrasine, abricin, abrin, abrusgenic-acid, abrusgenic-acid-methyl-ester, abruslactone, abrussic-acid, anthocyanins, calcium, campesterol, choline, cycloartenol, delphinidin, gallic-acid, glycyrrhizin, hypaphorine, N, N-dimethyl-tryptophan, N,N-dimethyl- tryptophan-metho-cation-methyl-ester, p-coumaroylgalloyl glucodelphinidin, pectin, pentosans, phosphorus, delphinidin, gallic-acid, glycyrrhizin, hypaphorine, N,N-dimethyl-tryptophan, N,N-dimethyl-tryptophan-metho- cation-methyl-ester, p-coumaroylgalloyl-lucodelphinidin, pectin, pentosans, phosphorus, picatorine, polygalacturonic-acids, precasine, precatorine and protein trigonelline.

– Root, known as Indian liquorice, is said to contain glycyrrhizin. It should not be used as a liquorice substitute, as it might contain toxic properties similar to the seed.
– Study of seed yielded, besides abrin, poisonous proteins, a fat-splitting enzyme, abrussic acid, hemmaglutinin, and a quantity of urease.
– Phytochemical screening yielded abrin, abrusoside E, abrusgenic acid, cycloartenol, gallic acid and glycyrrhizin.
– Phytochemical screening of crude extracts yielded tannins, triterpenes, glycosides, alkaloids, anthraquinones and carbohydrates.
– Studies on leaves have yielded various compounds, viz. abrine, trigonelline, abruslactone A, himiphloin, abrusosides (arbusosides A, B, C, and D), arabinose, galactose, xylose, choline hypaphorine, precatorine, glycyrrhizin, montanyl alcohol, inositol, D monomethyl ether, pinitol.
– Ethanolic extract of seeds showed alkaloids, flavonoids, phenols, tannins, and saponins. Ethyl acetate extracts yielded steroids and terpenes.
– Phytochemical analysis of aqueous extract of leaves yielded alkaloids, flavonoids (flavones), tannins, coumarins, sterols, triterpenoids, saponins, and reducing compounds.
– Studies on leaves have yielded abrine, trigonelline, abruslactone A, hemiphloin, abrusoside A, abrusoside B, abrusoside C, abrusoside D, arabinose, galactose, xylose, choline, hypaphorine, precatorine, glycyrrhizin, montanyl alcohol, inositol, D monomethyl ether, pinitol.

Properties
– Roots are sweet-tasting, neutral in effect, and antipyretic.
– Seeds are exceedingly toxic (not to be taken internally).
– Insecticide, disinfectant and suppurative.
– Toxic actions of abrin are very similar to ricin. Although less toxic, it is more irritant to the conjunctiva than ricin.
– Considered anti-inflammatory, abortifacient, purgative, anodyne, aphrodisiac, emetic, expectorant, febrifuge, laxative, sedative and vermifuge.
– Studies have reported neuroprotective, abortifacient, anticonvulsive, antiviral, antimalarial, antifertility, nephroprotective, antidiabetic properties.
