• Anti-Diabetic / Seeds: Study for antidiabetic activity of chronic administration of alcoholic extract of Celosia argentea seeds showed reduction of blood glucose in alloxan-induced diabetic rats. (3)
• Hepatoprotective Saponin / Cristatain: Study of seeds yielded a new saponin, cristatain, together with four other saponins, celosin A, B, C, and D. Cristatain exhibited hepatoprotective effect on CCl4- and DMF-induced hepatotoxicity in mice with decreases in ALT, AST and ALP. together with histopath evidence. (4)
• Lead / Phytoremediation: In a study of three ornamental plants for phytoremediation of Pb-contaminated soil, only Celosia cristata pyramidalis could be identified as a Pb-accumulator. (7)
• Antioxidant / Phytoremediation: Study of antioxidant compounds of a methanolic extract and solvent fractions of flowers showed the total polyphenol, flavonoids, and tannins contents were 6.80, 2.34, and 6.23 mg/g extract residue, respectively. DPPH and ABTS radical scavenging assays showed notable antioxidant activity. (8)
• Corrosion Inhibitor / Phytoremediation: Study of methanolic extract of CA showed antioxidant activity using DPPH and hydroxyl radical scavenging assay methods, similar to standard ascorbic acid. CA showed to be an efficient, eco-friendly, and low-cost corrosion inhibitor for MS (mild steel) in industrial water medium. (10)
• Anti-Inflammatory / Leaves: Study evaluated the anti-inflammatory activity of C. argentea leaves by carrageenan paw edema volume method in albino rats. Methanol and chloroform extracts showed maximal anti-inflammatory activity when compared to standard drug. The highest anti-inflammatory activity was observed in methanolic extracts. (12) Study isolated a flavonoid fraction from Celosia argentea. Flavonoid was evaluated for anti-inflammatory activity using carrageenan-induced rat paw edema and cotton pellet induced chronic inflammatory models. Results showed the flavonoid content possesses
significant dose-dependent anti-inflammatory activity in both models. (23)
• Wound Healing / Leaves: Study evaluated the healing efficacy of a 10% leaf ointment formulation using a rat burn wound model. Results showed a salutary action of the extract on wound healing which may be due to mitogenic and motogenic promotion of dermal fibroblasts. (13) Study for wound healing activity showed wound closure occurred earlier in treated rats. The salutary effect may be due to mitogenic and motogenic promotion of dental fibroblasts. (27)
• Antidiarrheal / Leaves: Study evaluated the anti-diarrheal effect of alcoholic leaf extract on castor oil-induced diarrhea, charcoal meal test and PGE2-induced diarrhea. Results showed dose related anti-diarrheal effect via a central effect and PGE2 inhibition. (14)
• Antibacterial: Study evaluated the antibacterial activity of different plant parts of Phyllanthus maderaspatensis and Celosia argentea extracted with different solvents. Of all the extracts Phyllanthus shoot (methanol) and Celosia inflorescence (ethanol) exhibited the maximum antimicrobial activity.
Pseudomonas was found to be more sensitive, while alcohol and ethyl acetate extracts exhibited the more significant inhibition. (15) Study of crude extracts of Datura alba and Celosia argentea leaves showed significant lysis zone against all pathogens, results comparable with antibiotic cream Silver Sulphadiazine. (•)
• Betalains / Leaves: Study evaluated the betalains of yellow, orange, and red inflorescences of common cockscomb (Celosia argentea var. cristata). Besides the known compounds amaranthin and betalamic acid, the three yellow pigments were elucidated to be immnonium conjugates of batalamic acid with dopamine, 3-methoxytyramine, and (S)-tryptophan. The detection of high dopamine concentration may be of toxicological relevance in use of yellow inflorescences as vegetable. (18)
• Anthelmintic / Leaves: Study evaluated various extracts of leaves for anthelmintic activity against adult earthworms Pheretima posthuma. Albendazole was used as standard. Aqueous and methanol extracts showed significant dose dependent paralysis and mortality. Aqueous extract showed more significant activity than the methanolic extract. Chloroform extract showed no significant activity. (19)
• Antinociceptive / Whole Plant: Study evaluated the antinociceptive activity of methanol extract of whole plant of C. cristata in mice pain models using thermal (hot plate, tail immersion test) and chemical (acetic acid, formalin, and glutamate-induced nociception test). Results showed significant antinociceptive effect associated with both central and peripheral mechanisms. The antinociceptive effect was significantly reversed by naloxone and glibenclamide, suggesting opioid and ATP-sensitive K+ channel system involvement. MECC also showed involvement of cGMP pathway in its antinociceptive action. (20)
• Effect on Trichomonas vaginalis In-Vitro: Study evaluated the effect of aqueous extract of Celosia cristata on Trichomonas vaginalis in vitro. The mortality rate of T. vaginalis increased with prolonged drug action and increased concentration of the drug. Treatment with CC aqueous extract showed a relatively potent effect of T. vaginalis—the cytoplasm of T. vaginalis was filled with granules and vacuoles, some rupturing with overflowing of cellular contents. (21)
• Impact on Adipogenesis of Native Human CD34+/CD31- Cells: Study evaluated the in vitro capacity of C. cristata extract to impact the adipogenic potential of native human adipose tissue progenitor cells, i.e., commitment and differentiation towards adipogenic lineage. C. cristata extract reduces lipid content of progenitor cells undergoing differentiation correlating with reduced expression of C/EBPα. Under commitment-inducing conditions, the extract induces a more potent reduction of lipid content. Results showed C. cristata extract decreases adipogenesis. Study suggests the extract impact the commitment of human adipose tissue progenitor cells. (22)

celosian, from Celosia argentea: Study showed antihepatotoxic
and immunostimulating effects. (26)

Mineral analysis yielded magnesium, zinc, lead, and iron. It showed concentration dependent mitotic inhibitory effect on mitosis of A. cepa, an indication of cytotoxicity. The antimitotic potential of the extract presents a potential for use in drug development for use in prevention of uncontrolled proliferation of cancer cells. (32)
• Antiurolithiatic Activity / Seeds: Study evaluated the antiurolithiatic activity of an ethanolic extract of CA seeds. Results showed antiurolithiatic activity, more efficacious at dose of 500 mg kbw. Results suggest a potent prophylactic effect on stone formation, a mechanism unrelated to its diuretic effect. (33)
• Benefits in Benign Prostatic Hyperplasia / Effect on PSA: Study evaluated the effect of leaves of CA on antioxidant status, PSA (prostatic specific antigen) and hematological parameters in prostatic rats.
