The work aims to improve the transmission of effective information and use safety of Yunnan Baiyao capsule products, so as to provide new ideas and methods for the research on traditional drug packaging design in China. Questionnaires, eye movement experiments and behavioral experiments were applied to analyze and evaluate the existing packaging design of Yunnan Baiyao capsule, and the targeted improvement was carried out. Eye movement hotspots charts showed that the front and reverse information of the outer packaging could not be effectively conveyed. Questionnaire analysis showed that, the attention frequency of the information such as drug specifications, dosage and taboos of the outer packaging was seriously unequal to the importance of information. Behavioral experiments indicated that the insurance was not easy to obtain. The regression equation between consumer purchase possibility and fixation numbers of eye movement index was obtained: Y=3.057+0.018X1, which is applied to improve the design of Yunnan Baiyao capsules. White and green are used as the main colors, and the effective color partition of the reverse information is presented to realize the effective transmission of information. The snap-on structure of the inner packaging to the outer packaging is used to prevent accidental ingestion by children.
