General appearance

Deciduous shrub of 3 to 6 m (up to 9 m) in height, with a diameter at breast height of 15 cm or more. Its leaves are alternate, compound, pinnate, 3 to 5 m long, leaflets 10 to 15 pairs per leaf, elliptical, 7 to 13 mm long and 3 to 5 mm wide, with aromatic resinous glands present. Branched stems dark brown. The outer bark, yellow with slightly rough texture, scaly when dry removable in irregular plates of dark color of 1 mm thick. In contrast, the reddish brown inner bark. Inflorescences arranged in terminal or subterminal spiky clusters, 5 to 7 cm long; campanulate calyx, 2.5 to 3 mm long, 5 lobed; white corolla, formed by 5 free petals, 5 mm long by 1.3 to 2 mm wide, oblong. It has slightly curved pods, attenuated at the apex, pubescent or subglabra, from 7 to 9.5 mm long, with the persistent, fragile and indehiscent style, provided with glands; Each pod contains a seed. And the seed coat is thin and stays in the water. The plant is hermaphrodite.

Major constituents

The flavonoids demethoxy-methylenedioxy-pterocarpan and hydrorotenone have been identified in the stem, the beta-sistosterol sterol and an unspecified structure component, the aglustegorretoside. In the bark of the stem have detected the same components in addition to triterpene beta-amyrin. In the heartwood, the flavonoid hydroxytrimethoxy isoflavone, and in trunk wood, flavonoids coatline A and B and coumarin flemichaparin. Several isoflavonoids were isolated from the cortex and reported the structure of four α-hydroxydihydrochalcones. In studies carried out on Eysenhardtia polystachya, several substances have been identified that have demonstrated cytotoxic and antimicrobial activity in experiments. In more recent studies, the effect of isoflavones isolated from the bark of Eysenhardtia polystachya on the growth of urinary crystals has been evaluated. However, the diuretic effect has not been evaluated.

Medical uses of Eysenhardtia polystachya

It is attributed properties such as, diuretic, antidiabetic and antimicrobial.

The medicinal uses (fruit, seed, leaf and bark) that have been attributed to it since the 16th century are diverse, for example, with the wood an infusion is prepared to which properties are attributed against kidney and gallbladder diseases, It is also used as a contraceptive. The leaves and stems in cooking are used to relieve the discomfort due to kidney stones and against abortion, the flower is used for diarrhea in children.

Pharmacology

In the twentieth century, its use as an antispasmodic, antipyretic, cicatricial and regenerative plant for eye diseases, among others, is mentioned.

However, it should be noted that the only therapeutic activities that have been scientifically evaluated are the antiinflammatory activities induced by the use of aqueous extracts (infusion and decoction at a dose of 200 mg / kg bw) and ethanolic (50 and 100 mg / kg). of pc) of the bark, trunk and leaves of sweet stick, in this same study it was observed that the use of these extracts to diminish the inflammatory process, does not cause gastroduodenal alterations in contrast with indomethacin; diuretics and against urolithiasis, demonstrating that isoflavones isolated from the cortex act as inhibitors in the formation and growth of oxalate and calcium phosphate crystals, reducing the degree of aggregation and the size of the precipitated particle. Also, isoflavans have been identified from the sweet stick bark that in experiments showed to have cytotoxic and antimicrobial activity.
