Q: Is it necessary to apply the "cough-relieving plaster"?
A: No.
As the name implies, "cough-relieving plasters" are for the purpose of alleviating cough. There are three types of " cough-relieving plasters " on the market: herbal patches, far-infrared patches, and Japanese imported cough-relieving.
The first two types are designed to alleviate coughing by irritating the acupuncture points with herbal preparations or far-infrared rays. However, the so-called "acupuncture points" themselves are just fictional, and it's useless for anything to work.
The main ingredient of the third type is Tulobuterol. Tulobuterol is a bronchodilator that can improve airway ventilation and relieve the symptoms of asthma and breathing difficulties of chronic obstructive pulmonary diseases (COPD).
Unlike other conventional oral or nebulized inhaled bronchodilators, Tulobuterol can be administered transdermally. It is a prescription drug that has no effect on the common post-cold cough, which actually with much side effects of allergies, palpitations, tremors, etc.
As for the effect of " cough-relieving plaster ", it is better to say that the disease heals itself. Cold is the most common cause of coughing and it lasts for a short time, which can be relieved by itself without the aid of any medication.
Therefore, the consumption of "cough patches" on the market are "blind consumption cost".
