Safety Overview
1.Brucea — Introduction & Highlights
Brucea javanica, commonly known as Brucea or Fructus Bruceae, and Ya-dan-zi in Chinese, is a resilient perennial shrub belonging to the Simaroubaceae family. This botanical entity is native to the tropical and subtropical regions of Southeast Asia, flourishing in countries such as Indonesia, Malaysia, Thailand, the Philippines, and southern China, including Guangdong, Guangxi, Yunnan, and Fujian provinces.
It demonstrates remarkable adaptability, thriving in diverse ecological niches from forest edges and open grasslands to disturbed areas and fallow lands. The plant typically prefers well-drained, slightly acidic to neutral soils and a consistently humid climate, often found at lower to mid-elevations.
Morphologically, Brucea javanica typically grows as a bushy shrub, reaching a height of 1 to 3 meters, though some specimens can attain up to 5 meters. Its robust taproot system provides firm anchorage, complemented by numerous fibrous lateral roots. The bark is generally smooth, grayish-brown, and may develop slight fissures with age.
A defining characteristic is its alternately arranged, distinctly pinnately compound leaves, which often measure 20 to 30 cm in length. Each leaf comprises 7 to 15 lanceolate to ovate leaflets, featuring a glossy, dark green adaxial surface and a paler abaxial surface, with finely serrated margins and prominent venation. The inflorescence consists of small, inconspicuous, yellowish-green to whitish flowers, arranged in axillary or terminal racemes or panicles, typically appearing during the rainy season.
Following successful fertilization, the plant produces small, ovoid to globular drupes, which transition from green to a mature reddish-brown or blackish hue. Each fruit encloses a single, hard, reddish-brown seed, which is the primary medicinal part.
