Ru Xiang (乳香): Frankincense in TCM — Invigorating Blood, Relieving Pain, and Healing Wounds
Learn about Ru Xiang (Frankincense resin) in Traditional Chinese Medicine — its ability to invigorate blood circulation, relieve pain, reduce swelling, and promote tissue regeneration. Explore its uses in trauma, menstrual pain, and joint conditions.
What Is Ru Xiang?
Ru Xiang (乳香), known in the West as Frankincense, is the aromatic resin of trees in the Boswellia genus, primarily Boswellia carterii and Boswellia bhaw-dajiana. In Traditional Chinese Medicine, it is classified as a blood-invigorating, pain-relieving herb with a distinguished history spanning over 1,500 years.
The resin seeps from cuts in the bark of the frankincense tree and hardens into tear-shaped droplets — hence the Chinese name “Ru Xiang” (乳香), meaning “nipple-shaped fragrance,” referencing the shape of the resin tears.

TCM Properties and Actions
Primary Actions
- Invigorates blood and unblocks meridians — moves stagnant blood to relieve pain
- Promotes tissue regeneration — accelerates wound healing
- Reduces swelling and dissipates nodules — anti-inflammatory and decongestant
- Relieves pain — especially pain from blood stasis and Qi stagnation
Why It Works
Ru Xiang’s acrid nature gives it a dispersing, moving quality. Its warmth unblocks cold-induced stagnation. Combined, these properties make it one of the most important herbs for treating pain associated with blood stasis — whether from trauma, menstrual disorders, or chronic joint conditions.
