Dear Balkar Ji,
This plant is indeed Acmella oleracea (L.) R. K. Jansen, Syst. Bot. Monogr. 8: 65. 1985. I collected this as a herbarium specimen from Panchmari Reserve forest during my Master classes.
Synonym:Spilanthus oleracea L., Syst. Nat. 2: 534. 1767; Li, Fl. Taiwan 4: 945, pl. 1256 [ as Spilanthus acmella (L.) Murr.]. 1978; Huang, Fl. Taiwan 6: 141. 1979 (as S. oleracea “Clark”).
Common Name: toothache plant, paracress, eyeball plant, peek-a-boo plant


Plants annual. Stems decumbent to usually erect, not rooting at nodes, green to red, glabrous. Petiole 2-6.4 cm long, glabrous to very sparsely pilose, narrowly winged. Leaf blade 5-10×4-8 cm, broadly ovate to deltate, base truncate to short attenuate, apex short acuminate to usually acute, usually glabrous on both surfaces, margins dentate. Peduncle 3.5-12.5 cm long, glabrous to very sparsely pilose. Heads discoid, 10.5-23.5 mm tall, 11-17 mm in diam. Receptacle 8.3-21.5 mm tall, 3.5-8.5 mm in diam. Involucral bracts 15-18, triseriate, herbaceous, entire to sinuate, sparsely ciliate; bracts of outer series 5 or 6, 5.8-7.3×2.1-2.8 mm, usually narrowly ovate to lanceolate or sometimes ovate, acute. Disc florets 400-600; corolla 2.7-3.3 mm long, yellow, 5-merous; tube 0.5-0.7 mm long, 0.2-0.4 in diameter; lobes 0.3-0.6×0.2-0.4 mm; stamens 1.4-1.7 mm long; achenes 2-2.5×0.9-1.1 mm, moderately to densely ciliate with straight-tipped hairs. Pappus of 2 subequal bristles, longer one 0.5-1.5 mm long, shorter one 0.3-1.3 mm long.

Medicinal Properties:The toothache plant requires constant moisture in order to prevent wilting, but do not overwater. The plant grows well in high humidity. Dead head the flowers after they have bloomed. This plant needs a well-drained soil and benefits from a layer of mulch. Regular light fertilizer applications are also beneficial
