Sore throat
For acute sore throats, eat half a lemon with the peel. Sour? But very useful! Lemon juice is also good for gargling: dilute it with water in a ratio of 1:3 and gargle every hour during the day. You can also use the juice to lubricate your throat 3 times a day in places where white plaque has accumulated.

Flu
Drink teas with medicinal herbs and lemon. It is good to brew it with calendula, mint, sage, horsetail and plantain. Such a mixture will maintain the calcium content in the body at a level. And calcium is a great helper in fighting fever.
