Synopsis

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

Guaco (Mikania glomerata or Mikania laevigata) is a medicinal plant traditionally used in South America, especially Brazil, to support respiratory ailments such as influenza, cough, and bronchitis. Historical use stems from indigenous knowledge and folk medicine, where guaco teas and extracts are consumed to relieve symptoms like congestion and cough, owing to its reputed bronchodilator, expectorant, and anti-inflammatory properties. The main active compound in guaco is coumarin, which is thought to contribute to these effects.

While there are some preclinical studies suggesting guaco may have bronchodilatory and mild anti-inflammatory effects, high-quality clinical evidence specific to influenza is sparse. Most research focuses on symptom relief in respiratory diseases rather than direct antiviral effects against influenza virus. The available scientific data are limited to animal studies or in vitro research, with very few (if any) rigorous human trials assessing guaco’s effectiveness for influenza specifically. Thus, its use for influenza is primarily justified by tradition, with only preliminary scientific support for general respiratory symptom relief.

In summary, guaco is widely used in traditional medicine for respiratory ailments, including influenza, but robust scientific validation for its efficacy against influenza in humans is lacking. The evidence supporting its use for influenza is therefore rated as 2 out of 5, reflecting a foundation of traditional use and limited scientific corroboration.
