Bronchostop Cough Syrup Review Of Effectiveness

Bronchostop Cough Syrup Review Of Effectiveness

One of the essential aspects of symptoms management that students learn during pharmacy practice classes is to ask patients if the cough there are experiencing is ‘dry/tickly’ or ‘chesty’ and based on presenting symptoms appropriate product is recommended. Bronchostop Cough Syrup seems to break this rule as it is marketed for both types of coughs.

What Is Bronchostop Cough Syrup Used For?


As taken from the product description, Bronchostop is a traditional herbal medicinal product used for the relief of coughs, including chesty coughs and dry, tickly, irritating coughs and catarrh. Bronchostop is based on traditional use only.

What Is Traditional Herbal Medicine?

In order to market a product as herbal medicine in the UK, one needs to apply for traditional herbal registration (THR). THR license is only given to products that are used for minor health conditions, where medical supervision is not required, and no claims are made as to treat major health conditions (Gov UK, 2016).

Bronchostop’s registration is based purely on ‘the longstanding use of thyme herb and marshmallow root’ as traditional herbal medicines and not on data gathered from clinical trials. Under THR rules, there is no need to prove that a product works (MHRA, n.d.).

Bronchostop Cough Syrup: a review of the main ingredients?

Bronchostop Cough Syrup contains the following main ingredients:

  • Thyme herb (Thymus vulgaris L.and Thymus zygis , herb)
  • Marshmallow root (Althaea officinalis )


thyme herb

Although there is insufficient information obtained from a clinical trial on the use and effectiveness of thyme in the treatment of productive coughs, there is evidence that thyme has been used safely for this purpose for at least 30 years (EMA, 2016).


Marshmallow root:

Preparations containing marshmallows can be used to treat irritation of the mouth or throat and associated dry cough. Studies supporting the use of marshmallow in the treatment of dry coughs are of poor quality; therefore, the use of marshmallow root medicines are based on their longstanding use (ibid).

Bronchostop Cough Syrup Review: Conclusion

Most coughs resolve without any treatment within three weeks. There is no evidence supporting the use of Bronchostop to relieve coughs. In fact, there is little evidence for or against the effectiveness of any OTC medication in the treatment of coughs (Cochrane, 2014).

Nevertheless, as with many other cough syrups, the soothing benefit of Bronchostop syrup may come from the properties of the syrup itself, rather than from the ingredients which are present in the formulation (Eccles & Mallefet, 2017).

Lozenges are also an effective means of medicine that mends a sore throat, Bronchostop Cough Pastilles are a type of lozenges that help relieve a sore throat.
