Productive cough

Good Evidence

Controlled trials of standardized ivy leaf extracts show meaningful symptom relief in acute productive cough and bronchitis.

How it works

Hederacoside C is hydrolyzed in the gut to alpha-hederin, which is thought to influence beta-2 adrenergic signaling and reduce mucus viscosity. This is the proposed basis for the expectorant and mild bronchodilator effects of standardized ivy leaf extracts. Clinical evidence supports symptom relief in productive cough and acute bronchitis with standardized ivy leaf products.

Dosage

Standardized ivy leaf products typically deliver about 9 mg of hederacoside C per serving, taken two to three times daily. Dose for children is adjusted by age and product.

When and how to take it

Usually dosed two to three times daily with or without food.
