Rating (out of 5): 2

Cinnamomum loureirii, also known as Saigon cinnamon or Vietnamese cinnamon, has a historical background in traditional medicine, particularly in Southeast Asia. In traditional Vietnamese and Chinese medicine, the bark and essential oils from this plant have been used to address various respiratory ailments, including coughs—especially dry coughs. The rationale is based on its warming, expectorant, and antimicrobial properties, which are believed to help soothe the throat and reduce coughing.

However, scientific evidence specifically supporting the use of Cinnamomum loureirii for dry cough is limited. Some laboratory studies have demonstrated that extracts from related Cinnamomum species possess antimicrobial and anti-inflammatory properties, which could be relevant to respiratory tract infections. Nevertheless, there are no robust clinical trials or well-designed studies directly linking Cinnamomum loureirii to relief of dry cough in humans.

In summary, while the traditional use of Cinnamomum loureirii for dry cough is well-documented in ethnobotanical sources and traditional medicine literature, scientific validation is still lacking, and the overall evidence is modest. Anyone considering its use should be mindful of the gap between traditional claims and clinical proof.
