About Ivy Leaf
Hedera helix leaf; saponins (hederacoside C, alpha-hederin) act as an expectorant. EMA recognizes use for productive cough, but most clinical trials are open-label or non-placebo-controlled, many in children.
What Ivy Leaf supports
- May ease productive cough as an expectorant — evidence is largely open-label, with few placebo-controlled RCTs.
