Many friends with pharyngitis carry throat lozenges all year round, and some even take them as candy. Is this practice desirable? In fact, taking lozenges can only relieve the condition, but not cure the root cause. Throat lozenges are drugs and have certain toxic side effects. Such as cool mint has contracted oral mucosa blood vessels, reduce inflammation and edema and pain, but the oropharynx is not inflammatory and often taken, the oral mucosa blood vessels are often contracted, prone to dry breakage, the formation of oral ulcers. Most of the throat lozenges made of Chinese medicine contain ice chips, which can clear heat and detoxify, antibacterial and anti-inflammatory pain relief, but easily cause slippage and abortion. In addition, lozenges usually also contain iodine, which has a good antibacterial effect but is also irritating to the oral mucosa, and long-term use may lead to dysbiosis and induce oral ulcers. The correct way to take lozenges is to place the tablet at the base of the tongue and take it as close to the throat as possible. Do not chew the tablets or swallow them, and speak less when they are in your mouth. It is best not to eat, drink or rinse your mouth for 30 minutes after taking the tablets.
