lozenges are not what they seem

i was attending my first voice production class today and a very big hoax was revealed to me. a multi-million dollar industry hoax. lozenges does more harm than good to you when you have a sore throat. it does nothing to aid the curing of sore-throats. all it does is numbs the throat. that's all. it sends the wrong signals to your brain that your are alright and you thinking you are alright, would inadvertently talk more or eat more chili stuff and aggrevate the situation further. this would only cause more damage to your voice and throat. lozenges are no different from your everyday sweets, perhaps with only the numbing agent within it making the difference. if you have a sore throat, drink more water and speak less. do not even attempt to whisper for whispering strains your vocal cords, whether you are ill or not.
