What menthol does in a cough or throat product

Suck a strong peppermint and the cold rush you feel comes from menthol. It acts on the nerve endings that sense cold, so the mouth, throat and nose feel cool and slightly numb even though nothing has actually cooled. A raw, tickly throat bothers you less for a while. That is the reason it turns up in cough syrups, slow lozenges, chest rubs and inhalant sticks.

Bro-Zedex Syrup: what is in the bottle

The menthol product stocked here is Bro-Zedex Syrup, a 100ml bottle of liquid taken by mouth. Menthol is one of four ingredients. Bromhexine thins the mucus sitting in the airways so a cough can shift it, guaifenesin loosens chest congestion, and terbutaline relaxes the muscle wrapped around the airways, which helps when breathing feels tight or wheezy. Menthol supplies the cooling taste and the soothing effect at the back of the throat.

A productive cough that brings up phlegm is the main use, along with bronchitis and wheezing, and the syrup is filed in the asthma and respiratory range. There is one size, the 100ml bottle.

Taking the syrup, and keeping it in good shape

Shake the bottle, because the ingredients settle between doses, then measure with the cup or spoon from the box and not a kitchen spoon. The pack gives separate amounts for adults and children. The cooling feeling wears off soon after swallowing, so doses are spread through the day for as long as the cough lasts. Store the bottle capped, in a cool place and away from sun.

Side effects, and where menthol needs care

Menthol is the mild member of this syrup. About the worst it does is sting or bring a rash on mint-sensitive skin under a rub. The effects people actually notice come from the other ingredients: terbutaline can cause shaky hands, a pounding or fast heartbeat, headache and restlessness, which often ease as the body adjusts, and guaifenesin or bromhexine can unsettle the stomach or cause nausea.

Swelling of the face, lips or throat, a spreading rash, or difficulty breathing needs urgent treatment. Menthol rubs are not used on babies and toddlers, because menthol can disturb breathing in very young children, and the same goes for putting a strong rub under a child's nose.

Is Bro-Zedex Syrup a cough suppressant?

No. It helps you cough up phlegm instead of stopping the cough. Bromhexine and guaifenesin loosen the mucus, and terbutaline relaxes tight, wheezy airways, which makes the syrup a fit for a wet, productive cough and a poor one for a dry, tickly cough.

Does menthol clear a blocked nose?

Not in a physical sense, since the swelling inside the nose stays much the same. Menthol makes the air you breathe in feel cooler and fresher, and that change in sensation is what people describe as a clearer nose. Inhalant sticks and menthol rubs are used for that feeling.

What does terbutaline do in Bro-Zedex Syrup?

It relaxes the band of muscle wrapped around the airways, so they open wider and breathing feels less tight. That is why the syrup is used for bronchitis and wheezing as well as a chesty cough. The same ingredient is behind the shaky hands and faster heartbeat some people notice.

Menthol or camphor, what is the difference?

Both come from plants and both are used in rubs, but they feel opposite. Menthol, from mint, sets off the nerves that sense cold, so the skin feels cool. Camphor, from the camphor tree, triggers warmth and a mild tingling. Some chest rubs contain both.
