As per S`haarangadhara there are seven types of decoctions:
1. Paachana 2. Deepana 3. S`hodhana 4. S`hamana 5. Tarpan`a 6. Kledana 7. S`hoshan`a I
Some important tips about the preparation of decoction:
1. Decoction must be prepared over mild heat otherwise strong heat may destroy the potency of the decoction.
2. While preparing decoction, the container should not be covered with a lid as it increases the heavy attribute of the decoction.
3. Decoction must always be used fresh. Boiling it again or a stale decoction has toxic effects on the body.
4. In general, a dose of the decoction of two Pala ( 80 ml ) is advised but it may change as per the disease and the strength of the patient and that of the disease.
e. g. Naagaraadi decoction is used in various conditions of fever.
