Herbal expectorant

ATC code: R05CA12(Hedera helix, leaf)

Brand names: Prospan

Updated 24 Sep 2026 · Methodology

Indications

Productive cough

Adjunct

Ivy syrup is the best-selling herbal cough product in Spain: Prospantus, Cinfahelix, Hedetus. The 2018 HMPC monograph recognizes well-established use of ivy leaf as an expectorant for productive cough in adults, adolescents and children from 2 years, and the AEMPS ficha técnica repeats the same wording. The quality of the evidence is worth knowing in advance: the updated systematic review by Sierocinski and colleagues (Eur J Clin Pharmacol 2021) found only a handful of randomized trials, most of them small and at high risk of bias, with a modest effect compared with placebo. So the product is well tolerated and written into European practice, yet a rapid end to coughing is not what it delivers. The ficha asks people to see a doctor with breathlessness, fever or purulent sputum.

The drug is promoted for these uses outside international guidelines. Each entry below is analyzed against AEMPS, FDA, EMA, Cochrane and major RCTs.

Common cold

Not recommended

«A herbal syrup at the first sign of a cold» sounds harmless, yet ivy does not shorten a cold. The updated systematic review by Sierocinski and colleagues (Eur J Clin Pharmacol 2021) on ivy preparations in acute upper respiratory infections found few trials and low-quality evidence, and the Spanish Guía-ABE chapter on upper respiratory catarrh says plainly that pharmacy cold remedies do not relieve symptoms meaningfully. Herbal origin guarantees no safety: the AEMPS ficha técnica bans the syrup under 2 years because of the risk of worsening respiratory symptoms and asks for a diagnosis in children aged 2 to 4 with lingering cough. If ivy syrup was advised as a course «to prevent colds», consider seeking a second opinion.

Asthma

Not recommended

The antispasmodic action of ivy saponins turns easily in advertising into a «natural bronchodilator for asthma». Ivy syrup does not become asthma treatment. The 2018 HMPC monograph describes one indication – an expectorant for productive cough – and assigns ivy leaf no anti-asthma role. Asthma maintenance rests on inhaled corticosteroids and an attack is relieved with a fast-acting bronchodilator: replacing them with a herbal syrup means losing control of the disease. The AEMPS ficha técnica asks separately to see a doctor in case of breathlessness. The danger here is delay: while a person drinks syrup, airway inflammation continues and the attack arrives on worse ground. If ivy syrup was offered as a replacement for an inhaler, consider seeking a second opinion from a respiratory specialist.

Mechanism of action

Dry ivy leaf extract holds triterpene saponins, chiefly hederacoside C and its metabolite alpha-hederin. A secretolytic and antispasmodic action is attributed to them: sputum thins and bronchial tone falls. The proposed mechanism for alpha-hederin is inhibition of beta-2 adrenoceptor internalization, leaving more receptors on the cell surface and raising sensitivity to the body's own adrenaline. The AEMPS ficha técnica puts it more cautiously: the mechanism has not been definitively established. The 2018 HMPC monograph classes ivy leaf as a well-established use preparation, an expectorant for productive cough in adults, adolescents and children from 2 years.
