Catharanthus roseus, commonly known as Periwinkle and Nithyakalyani in Tamil, is a globally distributed ornamental shrub.
Rich in source of alkaloids, it contributes significantly to health care with antibacterial, antimicrobial, antioxidant, anticancer, and antiviral properties.
Notable in cancer treatment; vincristine, and vinblastine, anti-cancer drugs, were discovered during studies for anti-diabetic properties.
Used historically for health issues such as gastritis, cystitis, enteritis, memory loss, toothache, circulatory disorders, chest complaints, throat infections, nose bleeds, bleeding gums, hemorrhoids, skin diseases like acne, dermatitis, and eczema.
Wound-healing property may be attributed to the phytoconstituents like flavonoids and tri-terpenoids, known for astringent and antimicrobial properties.
Habitat
Belongs to the Apocynacea family, evergreen Nithyakalyani (Catharanthus roseus) reaches a height of 1-2.5 meters.
Native to Madagascar but now found worldwide.
Phytochemistry
Nithyakalyani hosts bioactive constituents like reserpine, ajmalicine, catharanthaine, lochnerin, serpentine, lochnericin, vinorelbine, vincamine, and vindesine.
Late 1950s research suggests two additional alkaloids, vincristine and vinblastine, used in treating specific blood cancers.
Extracts explored for alternative treatment in conditions like high blood pressure, stroke, Wilms tumor, lymphomas, Kaposi’s sarcoma, neuroblastoma, Hodgkin’s disease, etc.
Nutritional Prowess
Nithyakalyani’s hypoglycemic property aids in controlling blood sugar levels by activating insulin production from β-pancreatic cells.
Active constituents in Nithyakalyani provide relief for respiratory disorders like asthma, bronchitis, COPD, cough, and cold symptoms.
Nithyakalyani acts as a natural antihypertensive agent, improving heart functions and maintaining balanced blood pressure.
With potent antioxidants and flavonoids, Nithyakalyani enhances memory, concentration, calmness, focus, and alertness.
Nithyakalyani’s antimicrobial and healing properties effectively treat wounds and prevent skin infections.
The plant’s anti-cancer properties boost immune power, reduce tumor size, and prevent metastasis, particularly in Leukemia and Hodgkin’s lymphoma.
Dermatological Perks
Loaded with alkaloids, Nithyakalyani combats oxidative damage from the sun, treating various signs issues.
Vincamine metabolizes into vinpocetine, delaying aging signs and maintaining skin youthfulness.
