BRONCHOSTOP syrup 240ml

Buttercup Bronchostop Cough Syrup is a traditional herbal cough medicine that treats tickly, irritating, dry and chesty coughs. It includes the active ingredients marshmallow extract and thyme, which form a soothing coating on your throat to suppress throat inflammation, reduce irritation, and relieve the urge to cough. It's suitable for adults, the elderly and children aged 12 and over, and contains thyme herb and marshmallow root extract.

  • Traditional herbal medicinal product
  • Non-drowsy formula
  • Soothes chesty and dry coughs

Buttercup Bronchostop Cough Syrup contains marshmallow root extract which forms a defensive and calming layer on your throat which eases throat inflammation, relieves irritation and helps lessen the impulse to cough. It also contains thyme extract to help thin phlegm, making it less gluey and thick, meaning mucus is more effortless to cough up (facilitates expectoration). The formula helps dry, chesty and irritating coughs, acting as a mild expectorant.

If you notice any of these symptoms when taking Buttercup Bronchostop Cough Syrup, seek medical advice right away:

  • Problems breathing or swallowing.
  • A rash on the skin.
  • Tongue, throat, face or lip swelling.


Other rarer side effects include:

  • A stomach upset.
  • Nausea.
  • Vomiting.
  • Diarrhoea.


If you notice these side effects or any others not listed here, discontinue taking Buttercup Bronchostop Cough Syrup and contact your doctor or one of our pharmacists immediately.

Is Buttercup Bronchostop Cough Syrup good for phlegm?
