Said by Backer (Flora Malesiana 1, 4: 85) to bear hermaphrodite or female flowers; I have not seen flowers without good anthers, but such certainly occur commonly in African Aerva lanata, while Aerva javanica, is dioecious, so female flowers may well be found at least occasionally in the present species.

Aerva sanguinolenta var. minor (Hance) H. S. Kiu (Guihaia 13: 105. 1993; A. scandens (Roxburgh) Moquin-Tandon var. minor Hance, J. Bot. 17: 14. 1879) was described from Guangdong, but we have seen no specimens and are therefore unable to treat it in this account. Further revisionary study is necessary. The species is used medicinally.

Perennial herb, frequently woody and suffrutescent below, prostrate to erect or frequently ± scrambling, 0.4-1-(2) m, branched from the base and usually also above, upper branches commonly long and slender. Stem and branches terete, striate, densely tomentose or canescent with whitish or yellowish, appressed or patent hairs (the lowest internodes sometimes ± glabrescent). Leaves and branches mostly alternate, the lower not rarely and all occasionally opposite; leaves broadly to narrowly ellipitic or elliptic-lanceolate or elliptic-ovate, cuneate to attenuate at the base, acute to acuminate at the apex, densely whitish-canescent on both surfaces (rarely green and only thinly hairy), those of the main stem below the inflorescence c. 1.5-18 x 0.8-6 cm, petiole up to 2 cm long; branch and inflorescence leaves gradually reducing. Spikes sessile (or pedunculate by reduction of branches), forming a lax raceme or terminal panicle, the lower axillary but the upper without subtending leaves, 0.5-8 x 0.4-0.6 cm, cylindrical (conical when young), silky, white to pale pink or pale brown; bracts 1-1.5 mm, deltoid-ovate, membranous with an excurrent yellowish midrib, thinly pilose, persistent; bracteoles similar to slightly smaller, also persistent. Flowers hermaphrodite or hermaphrodite and female. Outer 2 tepals hyaline, elliptic-oblong, tapering above with a distinct mucro formed by the excurrent midrib, 1.75-2.25 mm without the mucro; inner slightly shorter and narrower, acute, hyaline with a narrow central green vitta along the midrib, the vitta bordered by two fine lateral nerves and extending for about two-thirds of the length of each tepal; all tepals densely lanate dorsally. Sta¬mens delicate, at anthesis attaining about half the length of the style. Style and two short, divergent stigmas subequalling the ovary in length at anthesis. Capsule c. 1 mm. rotund, compressed. Seed 0.8-1 mm. reniform, black, shin¬ing, the testa shallowly but distinctly reticulate.

Hasil uji sitototoksik terhadap sel MCF-7 menunjukkan bahwa ekstrak etanolik daun tanaman sambang colok mempunyai nilai IC50 sebesar 423 μg/ml sedangkan uji doksorubisin pada sel yang sama mempunyai nilai IC50 sebesar 327,6 nM. Efek sinergis (yaitu CI < 0,9) muncul pada kombinasi ekstrak etanolik daun sambang colok – doksorubisin konsentrasi 211,7 μg/ml – 200 nM; 211,7 μg/ml – 150 nM; 158,8 μg/ml – 200 nM; dan 158,8 μg/ml – 150 nM. Hal ini menunjukkan bahwa kombinasi yang sinergis dapat terjadi pada konsentrasi di bawah setengah harga IC50 dari ekstrak etanolik daun sambang colok maupun doksorubisin [1]
