This formula was devised by Zhang Jie-bin (a.k.a. Zhang Jing-yue) and is a variant of Liu Wei Di Huang Wan (Rehmannia Six Formula), from which the three draining herbs have been removed and replaced with five additional tonifying herbs. Its clinical applications are much the same as those of Liu Wei Di Huang Wan, however it is used when a stronger tonic is required. Its actions are focused on nourishing the Kidney Yin-Essence, with minimal effect on reducing deficiency Fire.
