This is an empirical formula based on Dr. Fung's 60 years of clinical experience. According to Chinese medicine, aging results in the diminution of the fundamental substances, particularly essence and yang qi. Since the kidney rules the bones, insufficient essence leads to weakened bones, thus many elderly individuals are susceptible to bone fractures under circumstances that would not affect younger persons. This corresponds with the biomedical condition of osteoporosis. In this formula, the chief materia medica lu jin, strengthens the sinews and bones, as does gui ban. The latter two ingredients also nourish the yin and blood. To restore the kidney's production of essence, cistanche salsa (rou cong rong) is added to the formula. Blood must also be tonified and nourished in order to maintain production of essence; this is accomplished through the herbs tang kuei (dang gui), and rehmannia (shu di huang). Ligusticum (chuan xiong), spatholobus (ji xue teng), and ardisia (zou ma tai) invigorate the blood; the latter also strengthens the sinews and bones. Due to insufficient fundamental substances, the elderly are also prone to patterns of cold and stasis. Thus, in this formula, ardisia (zou ma tai), cinnamon twig (gui zhi), chaenomelis (mu gua), and evodia (wu zhu yu) are added to dispel cold and stasis. Codonopsis (dang shen) and licorice (gan cao) tonify the yang; the latter herb also harmonizes the herbs in the formula.
