Synopsis

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

Tolu Balsam (the resin from Myroxylon balsamum) has a long history of traditional use, particularly in South American and European herbal medicine, to support the bronchial and respiratory systems. Its use in this context is mainly for its soothing effects on mucous membranes and as an expectorant. Historical references document its inclusion in cough syrups, lozenges, and inhalations for bronchitis, coughs, and other minor respiratory complaints. The resin contains aromatic compounds, such as cinnamic and benzoic acids, which are believed to help loosen mucus and ease breathing, though the precise mechanisms are not well-defined.

However, modern scientific validation is limited. While some in vitro studies have shown mild antimicrobial and anti-inflammatory effects, robust clinical trials supporting its efficacy for bronchial conditions are lacking. The majority of the evidence for Tolu Balsam’s use in respiratory health comes from traditional practice, historical pharmacopeias, and anecdotal reports, rather than well-controlled scientific studies. Consequently, Tolu Balsam is still found in some herbal and over-the-counter preparations, but its use is primarily justified by tradition rather than contemporary scientific evidence.
