Mustasa is an erect, branched, smooth annual, 0.4 to 1 meter high. Leaves are oblong-obovate to oblong-lanceolate, 5 to 15 centimeters long, or in some cultivated forms much larger, thin, irregularly toothed or subentire, the lower ones sometimes lobed or pinnatifid. Flowers are yellow, 6 to 8 millimeters long. Pod is ascending, linear-lanceolate, 1.5 to 3 centimeters long, and somewhat contracted between the seeds. Beak is seedless.

- Widely distributed in the settled areas, in towns and houses, planted and spontaneous.
- Introduced from Asia.
- Now, pantropic; also occurring in some temperate regions.

Juncin / Antifungal Protein / Anti-Tumor: Study isolated juncin from the seeds of Japanese takana (Brassica Juncea var. integrifolia). The protein exhibited antifungal activity against Fusarium oxysporum, Helminthosporium maydis and Mycosphaerella arachidicola. It inhibited the proliferation of hepatoma and breast cancer cells. (2)
Anti-Diabetes Benefit / Seeds: Study showed feeding of a fructose diet containing 10% Brassica juncea seeds significantly reduced fasting serum glucose, insulin and cholesterol levels. Results suggest that B juncea can play a role in the management of pre-diabetic state of insulin resistance. (3) Study of an aqueous extract of seed showed potent hypoglycemic effect on STZ induced diabetic male albino rats. (17)
Hypoglycemic / Antihyperglycemic Effect: Study showed the B juncea diet showed significant antihyperglycemic effect in alloxan but not in STZ rats. (4)
Anti-Diabetic Oxidative Stress: Study of four fractions from mustard leaf (B juncea) showed the ethanolic fraction showed the strongest concentration-dependent inhibitory effect on the formation of advanced glycation products and free radical-mediated protein damage in an in vitro system suggesting a potential protective role against diabetes and/or its complications. (5)
Wound Healing: Study evaluated leaf extracts for wound healing activity in excision wound model in albino rats. An aqueous extract showed 94.94% maximum percentage of healing compared to control. (7)
Phytoremediation / Copper Contaminated Soil: Study evaluated the efficacy of copper removal from the soil by Brassica juncea and Bidens alba. The copper removal efficiency of B. juncea (L.) Czern was 11 times greater than Bidens alba DC var radiata. (8)
Phytoremediation / Municipal Solid Waste: Study showed highly promising potential for removal of Pb, Zn, Ni, and Cu by phytoextraction through Brassica juncea. B. juncea is a potential species for phytoremediation of MSW through management and regulation of leaching of toxic elements into soil and ground waters. The plant growth also stimulates the microbial community, degrading contaminants in the soil or making them available to rhizosphere. (9)
Anti-Hyperglycemic / Antinociceptive: Study of a methanol extract of leaves showed significant and dose-dependent antinociceptive activity in acetic-acid induced gastric pain writhing model in mice. In oral glucose tolerance tests, the extract also demonstrated significant and dose-dependent glucose lowering activity. (10)
Anthelmintic / Seeds: Comparative study evaluated the anthelmintic activity of seeds of B. juncea and flowers of B. oleracea against Pheretima posthuma, using Albendazole as standard. Results confirmed the anthelmintic activity of both plants, with Brassica juncea showing more efficient activity. (11)
Phytoremediation / Cadmium: Study showed the suitability of B. juncea for removing Cd from the soil. (13)
Anti-Inflammatory / Toxicity Study: Study evaluated the anti-inflammatory activity of PE and ethanolic extracts of B. juncea against carrageenan induced paw edema. Acute toxicity study up to 2 gm/kg p.o. did not show mortality or behavioral changes. Both extracts exhibited anti-inflammatory activity, with the ethanolic extract showing better activity than the petroleum ether extract. (14)
Antioxidant / Anti-Cancer / Seeds and Sprouts: Study evaluated extracts of Brassica juncea for hydroxyl radical scavenging activity and in vitro cytotoxicity activity against rat cancer cell line and three different human cell lines. Results showed effective scavenging of hydroxyl radicals and induction of cancer cell death by apoptosis. Seed extracts were more effective than sprout extracts. (16)
Hepatoprotective / Anti-Cancer / Seeds and Sprouts: Study evaluated the effects of Brassica juncea leaf extracts on carbon tetrachloride induced hepatotoxicity in Wistar albino rats. Among extracts tested, ethanolic and pet ether extracts showed maximum inhibition of necrosis and reduction of liver enzyme parameters with a significant p<0.0001. (18)
Genoprotective / Mercury-Induced Genotoxicity: Study evaluated the antigenotoxic effects of various concentrations of B. juncea chloroform seed extracts on mercury-induced genotoxic effects in root cells of Allium cepa. Results showed antigenotoxic potential in a dose dependent manner. (19)
Antinociceptive / Diabetic Peripheral Neuropathy: Study evaluated the effect of B. juncea on peripheral neuropathic pain in diabetic rats. Results showed decreased pain threshold and also significant decrease in diabetic induced hyperglycemia. Results suggest a therapeutic option for treatment of hyperalgesia associated with diabetic neuropathy. (
Antidepressant / Leaves: Study evaluated the antidepressant activity of methanol extract of B. juncea leaves in alloxan induced diabetic and non-diabetic rodents. Antidepressant and motor functioning depressing effects were observed. Compensations of monoaminergic deficits by the extracts in diabetic animals could be involved in the observed behavioral effects. (
Mustard Allergy / Double-Blind Placebo Controlled Challenge: A double-blind placebo-controlled study evaluated 30 patients presenting with positive prick tests to ground mustard seeds/ About 23% of sensitized subjects were allergic to routine dose of mustard. Positive prick tests and the presence of specific IgE were not predictive. Single-blind (SB) or double-blind (DB) placebo controlled food challenge (PCFC) trials is required before recommending avoidance diets. (22)
Antibacterial in Different Food Model Systems: Aqueous extracts of B. officinalis and B juncea showed various degrees of inhibitory activity especially towards staphylococci and enterobacteria; B. juncea showed higher inhibitory activity than B. officinalis. (24
