The aim of this study was to evaluate the shelf-life of Bojungikgi-tang (Buzhongyiqi-tang in Chinese) by long-term storage test. Experiments were performed to evaluate the stability such as the selected physicochemical, pH, identification, heavy metal, microbiological experiment, and amount of marker compounds under a long-term storage test of Bojungikgi-tang decoction. The significant change was not showed in pH, heavy metal, microbiological, and identification test based on long-term storage test. Furthermore, the HPLC analysis was performed for the determinations of liquiritin, glycyrrhizin, nodakenin, and hesperidin in Bojungikgi-tang by long-term storage test. We were calculated shelf-life of Bojungikgi-tang decoction based on the amount change of four constituents. Consequently, Shelf-life by four compounds at room temperature was predicted 23 month. The suggested shelf-life would be helpful on the storage and distribution of herbal medicine.

There are some controversies about the safety of herbal medicine. In order to examine the safety of herbal medicine, this study investigated the level of liver function test(AST/ALT) in patients taking herbal medicine for more than 6 months We checked liver function in 121 patients who took herbal medicine for more than 6 months. AST/ALT were measured before treatment and every 3 months (from 3 month to 9 month). In 121 patients taking herbal medicine for more than 6 months, mean AST level after 6 months was lower than before treatment and mean ALT level after 6 months was lower than before treatment. In 20 patients with abnormal AST/ALT before herbal treatment, 18 patients's AST/ALT changed to normal after 6 month herbal treatment. 2 patients's AST/ALT was slightly higher than normal. One woman patient met the criteria for herb-induced liver injury(HILI) with RUCAM scores 4 after taking herbal medicine for 6 months. Although her RUCAM score decreased to zero after taking herbal medicine for 9 months. This study suggests that long-term herbal medicine for 6 months or longer is very unlikely to injury liver function. Individual-specific liver damage may occur, it can be recovered.
