MANILA, Philippines - A recent study done by a university professor in Vigan City, Ilocos Sur discovered the anti-inflammatory properties of kalunay (amaranthus spinosus L.), a plant commonly found in tropical countries like the Philippines.
Mercita Queddeng, a professor at the University of Northern Philippines, said tests revealed the presence of alkaloids and saponins in the roots and leaves of the plant. These are chemical substances that are used in developing anti-inflammatory drugs.
Queddeng’s study was entitled, “Phytochemical, Microbiological and Antifungal Testing of Kalunay Leaves and Roots.”
Queddeng said the extract was screened against staphylococcus epidermitis, microsporum canis, and pseudomonas aeruginosa.
Staphylococcus epidermitis is a major cause of nosocomial infections, including sepsis in premature infants.
Infection caused by S. epidermidis is usually associated with medical devices, such as in-dwelling catheters and often occurs in people with weakened immune systems.
Microsporum canis, on the other hand, is a zoophilic dermatophyte, a frequent cause of ringworm in humans, especially children. It affects the hair, skin and rarely nails.
Meanwhile, Pseudomonas aeruginosa is a common bacterium which can cause disease in animals and humans.
The leaf extract, however, showed weak antimicrobial act against staphylococcus epidermitis, Queddeng said.
Kalunay, known as local spinach, is usually cooked along with other vegetables on an Ilokano recipe called dinengdeng.
Studies also showed that kalunay can be used as herbal remedy for kidney and other health problems.
In Cambodia, it is called pti banlar and used as a gray dye for cloth.
