Suixiangke, also known as "shican" or Teucrium japonicum, is a perennial herb with creeping stems. The stem is unbranched or branched, 50–80 cm tall, quadrangular with distinct grooves, smooth and glabrous, rarely with very sparse long soft hairs near the nodes. Petioles are 0.8–1.5 cm long; leaf blades are ovate-oblong to ovate-lanceolate, 5–10 cm long, 1.5–4.5 cm wide, much smaller on branches, acute or shortly acuminate at apex, cordate, subcordate, or truncate at base, with serrate or dentate margins. Except for occasional sparse short hairs at the base of petiole and lower midrib on the underside, the rest is glabrous. Pseudo-racemose inflorescences occur at the apex of main stem and upper branches; those on the main stem resemble panicles due to short lateral inflorescences below. Inflorescences are 3–4.5 cm long, glabrous, composed of densely packed, sometimes irregularly arranged verticillasters with two flowers each. Bracts are linear-lanceolate. Flower stalks are short (~1.5 mm), glabrous like bracts, occasionally sparsely pubescent. Calyx is campanulate, 4–4.5 mm long, 3–3.5 mm wide, slightly gibbous on one side below, with margin cilia only on teeth, 10-veined, five-toothed: upper three teeth broadly triangular and equal, lower two teeth acute-triangular and equal in length to upper ones, erect. Corolla white or pale pink, 1.2–1.4 cm long, scaly short hairs on lip externally, otherwise glabrous; corolla tube about 1/4 of corolla length, not exserted beyond calyx; lip and tube aligned in straight line; middle lobe well-developed, rhombic-obovate, spreading outward, nearly half as long as lateral lobes; lateral lobes ovate-oblong, acute at apex. Stamens slightly shorter than lip. Style equal in length to stamens. Disc small, disc-shaped, slightly wavy margin. Ovary globose, 4-lobed. Nutlets obovoid, ~1.2 mm long, chestnut brown, smooth, sparsely covered with whitish wavy hairs, adnate face exceeding half the fruit length. Flowering period: July to September.
