Treatment of hoarseness caused by flu

The consequences of the flu are reflected in the respiratory system, and causes hoarseness (roughness of voice). How can this be treated?

First: eat sauerkraut after each meal as much as we think we could drink. In addition, before bedtime eat raisins and Pinus halepensis (Aleppo pine)


Second: eat saffron with honey, in the morning and evening, mixed at a 1:10 ratio.
