Cymes are axillary, often with only one flower, rarely with 2-5 flowers; peduncle is thin, nearly as long as or slightly longer than petiole, glabrous, with 2-4 pairs of linear bracts at the bottom, alternately arranged; flowers are bisexual, campanulate, 2-2.5cm in diameter; sepals are 4, thick, ovate or oblong-ovate, 1.5-2.2cm long, 7-12mm wide, white or light yellow, obtuse at apex, sparsely covered with closely attached hairs on the outside, with white hairs on the margin, and glabrous on the inside; petals are absent; stamens are numerous, 1-1.2cm long, filaments are linear, with 1 vein, with long soft hairs on both sides, anthers are oblong, glabrous; carpels are numerous, covered with short soft hairs, and styles are covered with silky hairs.

[Properties] Identification of properties: The tuber is spindle-shaped, 6-12cm long, 0.6-2cm in diameter, and mostly curved rather than straight.

【Pharmacological action】

1. Analgesic effect The hot plate method, writhing method, and tail compression method of mice all proved that intraperitoneal injection of the alcohol extract of Psoralea corylifolia has a significant analgesic effect. The analgesic effect on pain response caused by mechanical stimulation is better and lasts longer. The effect of 300 mg/kg of Psoralea corylifolia alcohol extract is roughly equivalent to that of 50 mg/kg of Corydalis erythrorhizon, while the analgesic duration is significantly longer than the latter.

2. Sedative effect The results of the mouse hanging cage method experiment showed that after intraperitoneal injection of 300 mg/kg of Xuelikai alcohol extract, the number of activities was significantly less than that of the normal saline control group.
