According to the line of treatment, the patient having fever should keep his self on ‘fasting’ (langhan) up to first 48-72 hours, from the time of occurrence of fever. After 2-3 days, when patient feels hunger, gradually he should start the ‘Pachan Aushadhis’ (medicines which enhance digestion and metabolism) during 4-5 days. After 5 days usually the fever starts to fall down. So at the end, the patient has to take Ayurvedic medicines which destroyed the fever from its root.
