Snake-needle grass is a pleasant-tasting cooling, alterative herb that lowers fever, reduces inflammation, relieves pain and is diuretic and antibacterial[238]. It acts mainly on the liver and also stimulates the immune system[238]. The whole plant is alterative, anodyne, antibacterial, anti-inflammatory, antitumor, cardiotonic, depurative, diuretic, febrifuge and sedative[147, 176, 238]. The plant is harvested in the summer and dried for later use[238]. It is taken internally in the treatment of fevers, coughs, asthma, jaundice, impure blood, urinary tract infections, acute appendicitis, biliousness and cancers of the digestive tract[176, 238, 240]. Externally, it is used in the treatment of snake bites, boils, abscesses and severe bruising[176, 238].

Please identify this herb; s hygrophyte from Kannur, Kerala… probably a Rubiaceae member

It looks like a Hedyotis species, more of a juvenile H. herbacea

The images are of Oldenlandia diffusa.

Thanks, … Seems to match with images of Oldenlandia diffusa rather than those of Oldenlandia herbacea
