Er Zhi Wan: Two Ultimate Pill
Ligustrum and eclipta are sweet and cold and enter the liver and kidney meridians. They can nourish the yin without any cloying side effects. They are suitable for treating dizziness, tinnitus, blurred vision, weakness in the back and knees, and premature gray hair due to liver yin and kidney yin deficiency. Since they are not cloying in nature, and have gentle and steady actions, they can be used for a longer period of time in chronic disease. Moreover, these two herbs are also suitable in conditions where the blood is deficient and there is slight heat in the blood.
