Saluyot is a herbaceous vine that is a popular leafy vegetable in Southeast Asia. It is a good source of iron, vitamins B & C and calcium. Medicinal uses include treatment of gestational diabetes in pregnant women.
Also knows as:
Saluyot (Tagalog), Jute, Jew’s mallow, Egyptian spinach, jute mallow, bush okra, West African sorrel (En), Chang shouo huang ma (Ch). Krinkrin (Fr)
Saluyot (Corchorus olitorius) is an edible leafy vegetable that is a member of the genus Corchorus, classified under the subfamily Grewioideae of the family Malvaceae. Saluyot is widely found in tropical and subtropical areas from Asia to Africa valued as food and for its strong fiber. Saluyot has long been used as food staple since ancient times by Jewish people and Egyptians hence derived its English names Jew’s mallow and Egyptian spinach.
Saluyot leaves are very nutritious, it is rich in calcium, iron, protein, vitamin A, C and E, thiamin, riboflavin, niacin, folate, and dietary fibers. Saluyot is usually cooked as stew, forming a thick slimy syrup similar in consistency to okra usually taken with rice or other starchy staple.
Saluyot can almost grow anywhere in the Philippines. Saluyot is a hardy plant that is resistant to pests and requires little care. It can be found in the wild as it can also be grown in a farm.
Saluyot plants are tall, reaching 2-4 meters in height, having only a few side branches. Saluyot leaves are alternate, simple, lanceolate, about 5-15 cm in length tapering to a pointed tip and has finely serrated margin. Saluyot flowers are yellow about 2-3 cm wide with five petals. The fruit is capsule like with plenty of small seeds inside.
Corchorus olitorius leaves contains six phenolic antioxidative compounds The contents of these phenolic compounds, were determined, and their antioxidative activities were measured using the radical generator-initiated peroxidation of linoleic acid. The results obtained showed that 5-caffeoylquinic acid was a predominant phenolic antioxidant in Corchorus olitorius leaves. Source: Journal of Agricultural Food Chemistry. (1999 Oct)
A study aimed to evaluate the gastroprotective effect of an ethanolic extract of Corchorus olitorius against ethanol-induced gastric ulcers in adult Sprague Dawley rats showed that sambong extract posses gastroprotection in the experimental groups and medical benefits were comparable to that of the reference control medicine omeprazole.

A study investigated cytotoxic and genotoxic effects of leaf extracts (LE) and seed extracts (SE) of the Corchorus olitorius on the multiple myeloma-derived ARH-77 cells. Results have showed that both Saluyt leaf and seed extracts exerted cytotoxic effects on cells and the results of the comet assay revealed that the extracts induced genotoxic damage on ARH-77 cells. The leaf and seed extract treatments indicated that genotoxic damage significantly increased with increasing concentrations at relevant cytotoxic concentrations. Source: Pharmaceutical Biology.

Chromatographic fractionation of the methanolic extract of Corchorus olitorius (L.) yielded two polyphenolic compounds. The compounds when tested possess mild cytotoxic activity which was significant against HeLa cells at ⩾800μM. The plant Corchorus olitorius therefore represents a potential source of natural 'lead' compounds with anti-tumour potential. Source: Bioorganic & Medicinal Chemistry Letters. (2016 Aug)
A study conducted in Department of Biochemistry and Nutrition, India reported that by administering powdered Saluyot supplements to pregnant rats, both the mother and the fetus exhibited an increased resistance in diabetes induced oxidative stress versus a control group. The results suggest that Saluyot supplementation during pregnancy may provide beneficial effects against diabetes induced oxidative stress both for the mother and the fetus. (Journal of Diabetes. March 2013: Dietary supplementation with Ipomoea aquatica attenuates maternal and fetal oxidative stress in streptozotocin-diabetic rats)
A study was conducted to determine the antipyretic and anti-inflammatory effects of Corchorus olitorius root in Wistar rats. The results showed that Corchorus olitorius root extract (p<0.05) decreased the elevated temperature and inflammation compared with the control group.This study suggests that Corchorus olitorius root is another good source of phytomedicine that can be used effectively to treat inflammation and pyrexia that accompany some diseases.

The Department of Molecular Medicine, University of Malaya in Malaysia conducted a study on the protective action of Saluyot against thioacetamide-induced hepatotoxicity in rats to determine if Saluyot can indeed help treat jaundice. An ethanol extract of Saluyot has been administered to rats subjected to liver damage by thioacetamide. Results had shown that the rats when compared to a control group showed resistance against liver lesions, cell necrosis and inflammation. The study further suggests that the protective effect of Saluyot extract in chemical-induced liver damage might be contributed to its modulation on detoxification enzymes and its antioxidant and free radical scavenger effects. Moreover, it confirms a scientific basis for the traditional use of Saluyot for the treatment of liver disorders.

Saluyot being an annual plant can be grown in your backyard or can be bought in your local wet market by the bunch.
Saluyot leaves may be dried and stored for later use.
Saluyot leaves being a vegetable can be thrown in as an ingredient in making stews or soups and other viands. The Ilocanos are known to prepare delicious dishes with saluyot, the most popular are dinengdeng and bulang-bulang. Some Ilocanos even attributes their youthful looks and longevity in saluyot rich diet.
Saluyot is also available online in Amazon as listed :Saluyot Seeds (also known as Jute Leaf Mallow) Just check the label for recommended dose and usage.
