Mo Yao â Myrrh
Mo Yaoâthe resin of the myrrh tree (Commiphora myrrha)âis a classic TCM remedy that invigorates the blood and relieves pain. It belongs to the middle category and has been used since ancient times both internally for blood stasis and externally for wound healing. In Western tradition, myrrh is known as one of the three gifts of the Magi.
Effect from a Western perspective
- Myrrh contains sesquiterpenes, furanodienterpenoids, and essential oils, which have been shown in pharmacological studies to possess anti-inflammatory, analgesic, and antimicrobial properties. The active ingredient curzerene inhibits prostaglandin synthesis, which explains its pain-relieving effect at the molecular level.
- Clinical studies demonstrate accelerated wound healing through the promotion of fibroblast activity and the inhibition of pathogenic microorganisms such as Staphylococcus aureus. Positive results from controlled studies are available regarding its use for arthritis and inflammatory joint diseases. The antiseptic effect of myrrh tinctures on inflammation of the oral mucosa is well documented in European phytotherapy and recognized by Commission E.

The name MĂČ YĂ o is derived from the Arabic word murr (bitter)âa reference to the resinâs characteristic bitter taste.

Botany
Commiphora myrrha is a small, thorny tree or shrub in the family Burseraceae. It grows to a height of 3â5 meters, has silvery-gray bark, thorny branches, and small, trifoliate leaves. The aromatic resin oozes spontaneously from cracks or through deliberate incisions in the bark and hardens in the air into reddish-brown, irregular lumps.
The main growing region is located in the Horn of Africa and the Arabian Peninsula: Somalia, Ethiopia, Eritrea, Yemen, and Saudi Arabia. China imports all of its supply, as the plant is not native to East Asia.
