The active ingredients in traditional Chinese medicine have been reported to possess significant pharmacological activity and played an important role in clinical treatments. However, lots of the active ingredients in traditional Chinese medicine suffer from disadvantages such as low solubility, high melting point and low stability that results in low bioavailability and limit its clinical application. Crystal structure plays an important role in improving physicochemical properties and efficacy of the active ingredients in traditional Chinese medicine. This review concludes the research advances of several crystal forms used in the active ingredients in traditional Chinese medicine in terms of polymorph, cocrystal, amorphous/coamorphous and nanocrystal. And the effects of crystal forms on the physicochemical properties and efficacy of the active ingredients in traditional Chinese medicine were reviewed. This research may be useful for the formulation preparation and development of the active ingredients in traditional Chinese medicine.
