By Pinimenthol inhaler everything goes very simple: kettle on, leave some water, because it will be hot, but not to cook, previously pour in an ointment or preferred inhalant in the provided cup (package leaflet) and off you go with the Inhale. It is pointed out in the supplement that you should be careful before moving on to the mouthpiece, as vapors may be hot and strong, of course. I (Bronchoforton) equal pressed and inhaled my face in my use of ointment into the mouthpiece. But it does try out and investigate, not every get that! So be careful when inhaling. On the day I had a sore throat and shortly after they were gone. I will, especially in the winter time, this inhaler (good material processed (no cheap plastic)) use to prop up my airways again. Put on the table, it is very relaxing and easy for me to inhale the vapors and collect from time to time ,, fresh air ". I avoid it, exhale all the time in the inhaler. What I also could see that it is not a cheap plastic: It smells absolutely for nothing and is good for the skin. Also, the supplier "Medipolis" is highly recommended.
