Gargle with warm shungite water 5-6 times a day after each meal for three days. If you have a running nose, wash your nasal cavities as well. Have one third of a glass of alive (alkaline) water after gargling. Gargle for at least 1-2 min.
Your fever will be reduced on the first day. Full recovery can be expected within 2-3 days (possibly, in one day).
