Ivy, specifically Hedera helix (common ivy), is used in many over-the-counter herbal preparations to relieve cough, particularly in Europe. The active constituents in ivy leaf include saponins, which are believed to have expectorant (mucus-loosening), bronchodilatory, and anti-inflammatory effects. Several clinical studies and meta-analyses have investigated ivy leaf extract for the treatment of acute respiratory tract infections and cough, especially in children. While some studies have shown statistically significant improvements in cough frequency and ease of expectoration compared to placebo, the overall quality of evidence is moderate, with some trials limited by small sample sizes or methodological concerns.

Systematic reviews, including one published in Phytomedicine (2015), suggest that ivy leaf extracts may be effective and safe for reducing cough symptoms and improving respiratory function, though they also note the need for larger, high-quality randomized controlled trials. Regulatory bodies such as the German Commission E and ESCOP recognize ivy leaf as a traditional herbal remedy for productive cough. The European Medicines Agency classifies ivy leaf preparations as "well-established use" for productive cough based on available clinical data. In summary, there is moderate scientific support for the use of ivy leaf extract in the treatment of cough, particularly of the productive type, though more robust and standardized research is warranted.
