The theory of properties and flavors is one of the basic theories of traditional Chinese medicine. Composing formulas under its guidance is referred to as medicinal combination based on properties and flavors. This study describes the application of Lonicerae and Forsythiae in various prescriptions for syndromes based on the syndrome differentiation system of in wei-qi-ying-blood pattern identification of warm diseases. For wei level patterns

acrid-cool and bitter-sweet medicinals are preferred

and Lonicerae and Forsythiae are used to scatter and dissipate wind-heat. For qi level patterns

the two herbs can clear heat and resolve toxins; warm febrile diseases are treated with acrid-cool and sweet-cold medicinals

and the combined use of acrid-cool medicinals and the approach of transforming yin qi with sweet-bitter medicinals; acrid-cool and slightly bitter medicinals are preferred for warm toxin diseases; and acrid-cool and aromatic medicinals for damp heat diseases. In the treatment of ying level patterns

Lonicerae and Forsythiae eliminate heat in the ying level through the qi level; when pathogenic heat starts to enter the ying level

acrid-cool

sweet-cold

and aromatic medicinals should be considered; as the pathogenic heat grows intense in the ying level

and eventually overwhelms the pericardium

salty-cold and sweet-bitter medicinals should be chosen. Blood level patterns are to be treated with acrid-cool and aromatic medicinals

combined with Lonicerae and Forsythiae which clear heat from collateral channels. The rules for creating prescriptions were analyzed in this study from the perspective of medicinal combination based on properties and flavors

and corresponding clinical records were discovered in
