Synopsis

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

Guaco (Mikania glomerata or Mikania laevigata) is a plant traditionally used in South American, particularly Brazilian, folk medicine for respiratory ailments, including laryngitis. The primary traditional use stems from its reputation as an "expectorant" and "anti-inflammatory" herb, where decoctions or syrups are administered to relieve cough, hoarseness, and throat inflammation. The plant is rich in coumarin and other phytochemicals, which have been studied for their potential anti-inflammatory and bronchodilatory effects. However, scientific validation for its effectiveness specifically for laryngitis is limited. Some laboratory and animal studies suggest anti-inflammatory and smooth muscle relaxant properties, but there are no robust clinical trials directly evaluating Guaco for laryngitis in humans. Most references to its use are ethnobotanical or anecdotal, and it is officially listed in some national pharmacopeias as a traditional remedy for respiratory complaints. Thus, the use of Guaco for laryngitis is primarily justified by tradition, with some preliminary pharmacological rationale, but lacks high-quality scientific evidence.
