Buttercup Bronchostop Cough Syrup - 120ml

What Is Bronchostop Cough Syrup and Does It Work?

A cough can be exhausting — whether it's a dry, tickly irritation keeping you up at night or a chesty cough that just won't shift. Bronchostop cough syrup is a traditional herbal medicinal product designed to relieve both types of cough in adults and children aged 1 year and over. Available as a 120ml bottle, it's a convenient, over-the-counter option you can order directly from our cold and flu remedies range without needing a prescription.

The syrup contains two plant-based active ingredients — thyme herb dry extract and marshmallow root extract — which have a long history of use in European herbal medicine for respiratory complaints. It's registered under the Traditional Herbal Registration (THR) scheme in the UK, meaning it meets MHRA standards for quality and safety based on traditional use.

How Does Bronchostop Cough Syrup Work?

The two active ingredients work together to target cough symptoms from different angles:

• Thyme herb dry extract — acts as a natural expectorant and antispasmodic. It helps loosen mucus in the airways, making it easier to clear, and reduces the spasm reflex that triggers persistent coughing.
• Marshmallow root extract — forms a soothing, mucilaginous coating over the throat and upper airway lining. This helps calm irritation and reduces the urge to cough, particularly useful for dry or tickly coughs.

Together, these ingredients address both the productive (chesty) and non-productive (dry) cough types, which is why Bronchostop is often described as a dual-action cough remedy. The syrup format also means it coats the throat directly on swallowing, which may provide faster localised relief than tablet-based alternatives.

Who Should Use Bronchostop Cough Syrup?

This syrup is suitable for a wide range of people dealing with short-term cough symptoms. It's particularly well-suited to those who prefer a herbal or plant-based approach to managing their cough. That said, it's not appropriate for everyone — always read the label carefully.

• Adults and children aged 1 year and over
• People with a dry, tickly, or irritating cough
• People with a chesty cough with mucus
• Those who prefer a herbal, non-synthetic cough remedy

It is not suitable for people who are allergic to thyme, marshmallow, or other plants in the Lamiaceae or Malvaceae families. If you are pregnant, breastfeeding, or taking other medicines, speak to your pharmacist before use.

How Does Bronchostop Compare to Other Cough Syrups?

Is Bronchostop Cough Syrup Safe to Store at Home?

What Is Bronchostop Cough Syrup and What Is It Used For?

Bronchostop cough syrup is a traditional herbal medicinal product used to relieve the symptoms of dry, tickly, irritating, and chesty coughs. It is registered under the UK's Traditional Herbal Registration (THR) scheme, which means it has been assessed by the MHRA for quality and safety based on its traditional use. It is taken orally and is available without a prescription.

Coughs are one of the most common reasons people visit a pharmacist in the UK. The NHS notes that most coughs are caused by viral upper respiratory tract infections and typically resolve within three weeks. Bronchostop cough syrup is intended for short-term symptomatic relief during this period.
