Safflower is one of the oldest cultivated crops, its use dating back to ancient Egypt.
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. Flowering heads are large, surrounded by a cluster of leafy bracts which gradually become the bracts of the involucre, 2.5 to 4 centimeters across. Flowers are orange-red. The achenes, often deformed, are obovoid, usually 4-ribbed and truncate at the top. Pappus is absent or scalelike.

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.

Further study on underlying mechanisms may provide novel strategies in breast cancer therapy. (37)
• Depigmenting Effect / Seed: Study evaluated the skin depigmentation effect of extracts of three herbs viz., C. tinctorius seed, Cyperus rotundus and Schizonpeta tenuifolia. Results showed C. tinctorius seed extracts reduced tyrosinase activity and melanin formation of B16F10 melanoma cells. The underlying mechanism for its whitening activity may be the inhibition of tyrisinase, MITF, tyrosinase, TRP-1 and TRP-2 expression. Results suggest a potential as natural function ingredient with a depigmentation effect. (38)
• Antifungal / Aspergillus flavus: Study evaluated various extracts of medicinal herbs (thyme, senna, mentha, basil, safflower) on the growth of A. flavus, one of the major fungal challenges in agriculture and food industry. While all concentrations of the plant extracts significantly inhibited the fungus growth, the extracts of thyme and safflower manifested the most effective prohibition compared to benomyl with MIC of 200 and 400 µg/mL, respectively.
