Botany
Salasik-lupa is a spreading, diffuse, branched herb, with branches 15 to 45 centimeters long. Leaves are stalkless, rough, rigid, slender, elliptic- or linear-lanceolate, 3.5 to 6 centimeters long, 2 to 5 millimeters wide, and pointed at both ends. Flowers are borne in clusters in the axils of the leaves. Calyx-teeth are triangular. Capsules are smooth, ovoid, and 2.5 to 3 millimeters long.

Distribution
- In open places, old clearings, and thickets at low altitudes, from northern Luzon to Mindanao, in most islands and provinces.
- Also occurs in India to southern China and Malaya.

Constituents
- Leaves have yielded kaempferitin, the 3,7-dirhamnoside of kaempferol.

Parts used
Whole plant.

Uses

Folkloric
- Plant used for making poultices; applied for headaches; in small children applied to abdomen for stomachaches.
- Decoction of plants drunk for dysentery.

Studies
Antioxidant / NO Inhibitory Activity:
In a study of the methanol extracts of seven Malaysian medicinal plants, including Hedyotis verticillata, all showed strong antioxidant activity comparable to or higher than a-tocopherol, BHT and quercetin in the FTC and TBA methods. In one assay, H verticillata was one of five that showed strong NO activity inhibition in LPA and IFN-g-induced RAW 264. (1)

Availability
Wild-crafted.
