Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Benzoin siam (resin from Styrax tonkinensis) has a long history of traditional use for infections, particularly in forms such as tinctures, balms, and inhalations. In traditional medicine systems—including those in Southeast Asia and Europe—benzoin resin has been applied topically for wound care, minor cuts, and sometimes as a protective, mildly antiseptic dressing. Its role in steam inhalations for respiratory infections is also widely documented, often as part of "Friar's Balsam" or similar compounds. The resin contains compounds such as benzoic acid and cinnamic acid, which do have mild antimicrobial properties in vitro. However, these effects are relatively weak compared to standard modern antibacterial agents.

There is minimal scientific evidence supporting its efficacy for treating bacterial infections. The antimicrobial activity demonstrated in laboratory studies does not necessarily translate into significant clinical benefit when used in traditional preparations. The primary support for benzoin’s use against infection remains traditional and historical, rather than evidence-based. Clinical trials or robust pharmacological studies are lacking. As such, while Benzoin siam is still included in some over-the-counter preparations for minor skin or respiratory issues, its role is best understood as a traditional remedy with limited scientific backing for its antibacterial effects.
