Bazhen Wan (Chinese: 八珍丸) is a brownish-black pill used in Traditional Chinese medicine to "replenish qi and blood". It is slightly bitter and sweet in taste. It is used when there is "deficiency of both qi and blood with sallow complexion, anorexia, lack of strength and excessive menstrual discharge". A honey solution is used as a binding agent to make the pill.
