Chinese Eaglewood

Aquilaria sinensis

For well over a thousand years, healers across China have prized the fragrant heartwood of this quiet forest tree, known as chen xiang, as a warming remedy for a troubled stomach, a tight chest, and a wandering mind. The wood itself is unremarkable until the tree is wounded, at which point it slowly transforms its injury into something extraordinary: a dark, resin-laden heartwood so aromatic it became a treasured incense from Japanese kodo ceremonies to temples across the Middle East and Southeast Asia. In traditional Chinese medicine, small shavings of this resinous wood were folded into formulas meant to guide the body's energy downward, easing nausea, wheezing, and the kind of dull abdominal ache that would not settle. Its scent alone, released as smoke, was traditionally thought to steady an anxious spirit.

Safety.

Aquilaria sinensis and its resinous heartwood are not known to be toxic in the modest amounts traditionally used, but a few real cautions apply. The tree and most wild Aquilaria species are protected under CITES due to severe overharvesting for the incense and perfume trade, so only purchase agarwood, oud oil, or chen xiang from a sustainably grown or certified source, never wild-poached material. Traditional Chinese medicine reserves this herb for small, carefully measured doses within larger formulas rather than everyday use, and it is generally avoided during pregnancy and by those with weakened digestion without professional guidance, as it is considered a strongly warming, energy-moving herb. Much of the "agarwood" sold commercially is diluted, synthetic, or from unrelated wood, so quality and purity vary widely. As always, speak with a qualified herbalist or healthcare provider before using it medicinally, especially alongside other medications.
