Acute Illness
The simplest and quickest method of recovering from attacks of acute illness, fevers, inflammatory diseases, etc., is to rest quietly in bed in a warm but well-ventilated room, and to take three meals a day of fresh ripe fruit, grapes by preference. If the grapes are grown out of doors and ripened in the sun so much the better. I have found from two to three pounds of grapes per day sufficient. If there is thirst, barley water flavoured with lemon juice should be taken between the meals.
