You should drink nettlebroth three times in the month of March for good health because a man had an only son, the son got sick and his father tried all sorts of cured but the young man died. After his death his body was examined to see what was the cause of death. Around his heart a cup was found. His father kept the cup for drinking. The third time he put nettlebroth in it, it melted away. So they said that if the boy had got nettlebroth three times he would be cured.
