Description:

Note: Apparently Orthosiphon is being promoted as an herbal remedy for weight loss. This species is known to be a diuretic and can thus result in temporary weight loss through the loss of water. I have been unable to locate reliable information regarding any effect on fat. Be aware that herbal remedies can be promoted with virtually no scientific evidence as to their efficacy or side effects. It's strictly buyer beware!

"[S]lender perennial herb to 2 m high, the branchlets 4-angled, sparsely puberulent to glabrescent, sometimes purplish; leaves petiolate, the petioles 1-2 (-4.5) cm long, puberulent, the blades lanceolate to ovate or rhombic, 2-9 x 1-5 cm, chartaceous to membranaceous, cuneate at base, acute to acuminate at apex, coarsely serrate at margin (especially above middle of blade), glabrous to puberulent on both surfaces; racemes 10-15 (-20) cm long, the verticils lax, distant, the bracts sessile, ovate, 1-2 mm long, ciliolate, the pedicels to 4 mm long; calyx curved-campanulate, the tube to 3 mm long at anthesis, 10-nerved, scabridulous on nerves, the upper lip ovate, to 3 x 2.5 mm, the lower lip longer, the median lobes acuminate-aristate; corolla white or pale blue, 10-16 (-20) mm long, the tube 10-15 mm long, straight, strigose-tomentose without, the upper lip shallowly 4-lobed, recurved, the lower lip as long as upper lip, concave; stamens glabrous, coiled in bud, the anthers purple; style 5-6 cm long, glabrous, clavate and briefly 2-lobee at apex, white, purplish distally; nutlets ovoid-oblong, to 2 mm long, glabrous, rugose" (Smith, 1991; pp. 227-228).

Habitat/ecology: Naturalizes along roadsides, in stream bottoms and wet places. Often a cultivated plant. In Fiji, "cultivated in villages and gardens at elevations up to about 200 m, and sometimes naturalized along roadsides" (Smith, 1991; pp. 227-228).

Propagation: Seed

Native range: India through southeastern Asia and the Nicobars and throughout Malesia to Australia (Smith, 1991; pp. 227-228).
