Kasubha is an erect, branched, smooth herb, 30 to 90 centimeters high. Leaves are stalkless, half-clasping, lanceolate, 5 to 10 centimeters long, 1 to 2.5 centimeters wide, but smaller toward the top, with margins minutely spiny toothed.

• Cardioprotective Against LPS-Induced Apoptosis: Study showed Carthamus tinctorius possesses the ability to suppress JNK activity and inhibit LPS-induced TNF-a activation and apoptosis in H9c2 cardiomyoblast cells. CT can potentially cardioprotective against LPS-induced apoptosis. (1)
• Cardioprotective / Ischemia-Reperfusion Injury: Study showed Carthamus tinctorius extract could protect myocardium damage induced by I/R injury. The mechanism of cardioprotection may be associated with inhibition of apoptosis of myocardium, upregulating protein expression of Bcl-2 gene and downregulated protein expression of Bax gene. (7)
• Renoprotective: Study showed injection of safflor significantly reduced the renal dysfunction and injury caused by I/R (ischemia/reperfusion) of the kidney, effected probably due to inhibition of cell apoptosis and caspase-3 gene expression.
• Tracheloside / Anti-Estrogenic Lignan Glycoside: Tracheloside, isolated from the seeds of CT significantly decreased the activity of alkaline phosphatase, an estrogen-inducible marker enzyme, against cultured ishikawa cells, at a level of inhibition comparable to tamoxifen.
• Anti-Atherosclerotic / Antioxidant / LDL-Lowering: Study showed serotonin derivatives of extract of safflower seeds attenuate atherosclerotic lesion development possibly through inhibition of oxidized LDL formation through strong antioxidative activity.
• Neuroprotective: Study showed HSYA (hydroxysafflor yellow A) dose-dependently improved the neurological deficit scores and reduced the cerebral infarct area in a potency similar to the therapeutic effects of nimodipine on cerebral ischemia.
• Antioxidant / Safflor Yellow: Study showed SY is an antioxidatve part of Carthamus tinctorius.
• Polyphenols / Lipid Benefits: Study showed safflower polyphenols improved blood lipids by increasing the HDL-cholesterol formation and cholesterol excretion without significant uterotropic action in estrogen-deficient animals.
• Flavanoids / Antioxidants: Study isolated eight flavonoids. Luteolin-acetyl-glucoside and quercetin-acetyl-glucoside showed potent antioxidative activities.
• Teratogenic and Cytotoxic Effects of Safflower Extract / Coloring and Flavoring Use: Study showed that in higher doses, changes in cellular orientation and cellular degeneration were observed. also, cytotoxic assay demonstrated a concentration-dependent cytotoxic effect of the carthami flos extract. It suggests reconsideration of use as food additive.
• Hypotensive Effect: Study using SY, a mixture of chalconoid compounds extracted from CT lowered the blood pressure of spontaneously hypertensive rats. Results suggest the decrease to be mediated by the renin-angiotensin system.
• Breast Cancer Inhibitory Effect: The compound Zhyu-xiang, derived from extracts containing ginseng and carthamus tinctorius, was studied on treatment of MDA-MB-231 breast cancer cell and human mammary gland cell lines. Zhu-xiang showed significant dose-dependent inhibition in cell proliferation, greater than that of commonly used cytotoxic drugs. The inhibitory effect was due to induction of apoptosis, both time- and concentration-dependent. Results suggest Zhu-xiang could be a useful anticancer compound against breast cancer.
• Immunomodulatory / Antitumor Activity: Study showed the Carthamus tinctorius could promote immunity through the activation of DCs per se.
• Analgesic Activity: Study showed CF oil extracted from safflower seeds is a natural local anesthetic with moderate analgesic activity mediated through influences on the serotoninergic and monoaminergic pathways. It has a potential to occupy a leading place among local anesthetics used in traditional medicine, acupuncture, and medical massage. (4)
• Quinochalcones / Anti-Inflammatory: Study isolated two new quinochalcone compounds - saffloquinoside A and saffloquinoside B - from the florets of C tinctorius. Saffloquinoside A exhibited middling anti-inflammatory activity. (5)
• Bone Formation Benefits: Study in Sprague-Dawley rats showed a significant increase of osteoblast markers - osteocalcin and bone-specific alkaline phosphatase. The effect appears likely to be mediated by IGF-I at the early stages of treatment. (6)
• Antioxidant / Radical Scavenging: Study of crude extract showed antioxidant activities in various assays: DPPH scavenging, ABTS+ radical scavenging and superoxide anion radical scavenging. (9)
• Antidiabetic / Hypolipidemic: Study of a hydroalcoholic extract in diabetic male Wistar rats showed decreases in FBS, triglycerides, LDL and VLDL. Blood sugar lowering effect was comparable to glibenclamide. (10)
• Antitumor: Study evaluated the antitumor activity of CT extract on dendritic cell (DC)-based vaccine in cancer treatment. Results showed a dose-dependent dramatic increase of the levels of TNF-a and IL-1ß, with more immunologic and co-stimulatory molecules expressed on the DC surface. (11)
• Hepatoprotective: Study of a methanolic extract showed a hepatoprotective (antioxidant and anti-inflammatory) effect against CCl4-induced hepatotoxicity in rats as evidenced by biochemical parameters and histopathological findings. (12)
• Hypolipidemic / Effects on Gene Expression: Study evaluated the hypolipidemic effect of various fractionation of crude extract. Results showed the dichlormethane extract to reduce the total cholesterol/HDL-cholesterol of hyperlipidemic rats. The results may partly be due to a decrease in the HDL-cholesterol and gene encoding enzymes of the cholesterol biosynthetic pathway. (13)
• Antiulcer: Study showed an extract from Ct showed an antiulcerogenic effect, which may be due to its calcium channel blocking activity. (15)
• Hair-Promoting Growth: Study examined the potential of hydroxysafflor yellow A-rich C. tinctorius extract on hair growth in vitro and in vivo. C. tinctorius floret ethanolic extract promoted the proliferation of both dermal papilla cells and HaCaT and significantly stimulated hair growth-promoting genes. It suppressed expression of transforming factor ß-1, the hair loss-related gene. Results suggest a potential for use as a hiar-growth promoting agent. (17)
• Anti-Infammatory / Heme Oxygenase-1 Induction: Heme oxygenases (HO) are cytoprotective enzymes that degrade heme, generating CO, bilirubin, and ferrous iron, products with antioxidant, antiapoptotic, antithrombotic, and anti-inflammatory actions. Study evaluated methanol exhibited anti-inflammatory action , probably through induction of HO-1 expression via Nrf2 translocation and inhibition of NF-kB activity. (18)
• Stimulation of Melanogenesis / Gray Hair Treatment: Study evaluated the effect of Carthamus tinctorius floret ethanolic extract on melanogenesis in murine melanoma cells. Results showed the CTE can stimulate melanogenesis at the transcriptional levels without cytotoxicity, with a potential as a gray hair treatment product. (19)
• Female Reproductive Concerns: Study evaluated the possible effects of C. tinctorius on ovarian histomorphology and levels of female reproductive hormones in mice. Treatment with extracts showed detrimental effects with reduction in the number of ovarian follicles with an increase in atretic follicles, together with decrease in blood levels of FSH and estrogen. (22)
• Antidiabetic: Study evaluated the effect of C. tinctorius on fasting blood glucose and insulin levels in alloxan induced diabetic rabbits. Results showed significant hypoglycemic effect together with significantly increased insulin levels in extract treated and glibenclamide treated groups as compared to diabetic control. (23)
