There’s a lot of abdominal flu with a fever. In such a case, or even with the classic virosis, where you want to reduce the heat (above 38.5 degrees C), cast a little pure alcohol (with abdominal virosis a better juniper) and place over the belly button and glue. Leave until the heat drops. If it dries, replace it in between. The belly button is a very important part of our body, the shape tells us how much vital energy a person has. Bach drops can also be massaged over the belly of the navel.
