Effects: for chest and abdominal distension and pain, stomach cold vomiting and retching, kidney deficiency gas reversal asthma.
Sedum is the resin-containing wood of the white wood of the Ruixiang family. Trees, 5-15 m high, bark dark gray, a few smooth, fibers tough; branchlets terete, with crepe, sparsely pilose when young, and then gradually fall off, glabrous or nearly glabrous. Guangdong, Hainan, Guangxi, Fujian. Preferably in low elevation mountains, hills, and roadside sunny places in sparse forests.
The resin accumulated after the old stem is injured, commonly known as incense, can be used as raw materials for spices, and as a cure for stomach problems; bark fiber is flexible, white and delicate can be used as raw materials for high-grade paper and artificial cotton; xylem can be extracted from the aromatic oils, and the flowers can be used to make extracts.

Growing environment:
The incense tree is 5m-10m high, mostly born in mountainous rainforests or semi-evergreen monsoon rainforests, China's incense is mainly distributed in Guangdong, Hainan, Guangxi, Yunnan, Fujian and other provinces and districts, generally grows at an altitude of 400 meters below sea level, in Hainan up to 1,000 meters above sea level; Guangdong Province, the unique climatic conditions that make this place to be the Suitable for incense tree growth place, so there is also "China's incense township" reputation.
Species Status:
In recent years, due to the low natural reproduction rate of the incense tree, man-made predatory logging and other reasons, the domestic production of incense is seriously insufficient, while the market demand continues to expand, the contradiction between supply and demand is prominent. After realizing the market value of incense, not only incense farmers, incense-producing areas of the local government also joined the incense industry in the battle, have introduced relevant policies to support the incense industry.
