Fig. 1. Characteristics of EH-CS extracts by different combination ratios. (A) The extraction yields of combination extracts of different EH-CS ratios. (B) pH measurements of water-eluted EH-CS extracts. I-S2, I-S3, I-S4 indicates that the samples were prepared by mixing sole EH extract and CS extract after their extraction process with same EH-CS ratios for comparison. EH: Ephedrae herba, CS: Coicis semen, I-S: mixed sample of individual extracts.
