Core Tip

Core tip: Our study group had raised the hypothesis of tissue pharmacology of an herbal recipe, which assumed the effect of an herb formula is related to its target tissue distribution or concentration of effective components in target tissues. This study was then designed to screen the optimal oral dosing time of Da-Cheng-Qi decoction (DCQD) in rats with acute pancreatitis based on the pharmacokinetics of the main absorbed components and the pharmacodynamics of DCQD targeting of the pancreas.
