lemon cure
The close to infallible method which cures colds by drinking fresh lemon juice (from 5 to 10 lemons) with a straw.
In a book called "Las Plantas Curan," published in the 1960s in Brazil, which listed the most popular herbs and the illnesses they cure, I read about the 'lemon cure.' Whenever I catch a cold, via a straw I drink the juice from 5 to 10 lemons and they cure me every time. However, one time I did have to go to the doctor and she gave me some antibiotics because I had a fever, in the summer—imagine!
