金石类药物的药性，坚硬刚烈且作用迅猛。同时其本性清净，厌恶污秽杂质。凡是服用乳石之后，就必须用心调理身体，遵循查找古代流传下来的方法。
为什么要这样说呢？年轻人筋骨力量充沛旺盛，饮食充足饱足，身体会更加精明壮健，最终没有发病的道理。而到了年老岁暮，气候（指人体阳气或生命力）衰竭，饮食如果不适宜，这种石头的药气就会胜过人体正气，没有不引发疾病的。纵观其中的得失，没有比这更明显的了。人年轻时，即使不吃肉食，气血自然强盛；年老体弱时，即使吃精细的肉食，仍然不能保持健康。由此说来，这就证明古法是有疏漏的。
大凡人的血脉，经络运行应当不绝如缕。如果血脉中有轻微的瘀滞，就容易在瘀滞处发生疮疡或者发热，导致神志昏沉闷乱。一定要预防这种情况，每天早晚，温服一两盏清酒以通利血脉。所以不必等到违背时令的时候才去调理。现在看到那些调养得当的人，并不发病；又见到名医评论服用石药的人，常常通过清热的方法来调摄身体。倘若发病，调理适应就容易了。假如石气发动，暂时需要宣泄，服用少量寒凉药物，就能促使排泄通畅。如果得到通畅，热气就会一并消除。如果平时总是用寒凉的方法调摄，一旦石气发动，使用寒凉药物就无法起到转泻的作用。这里所说的道理，现在特意保留下来，只是为了广博见闻，展示如何调摄身体。都必须根据自己的本性，以冷热作为观察指标，务必追求安稳，不可固执于石药的论述，舍弃自己的实际情况而盲从他人。希望通达玄理的君子能对此留意。

The nature of metallic and mineral substances is hard, rigid, rapid, and intense. Furthermore, their character is pure and clear, and they abhor impurities. After taking rushi (milk stone), one must carefully regulate the body by referring to and following ancient methods.
Why is this so? In youth, when sinews and bones are full and vigorous, and diet is abundant and satisfying, the body becomes more alert and robust, with no likelihood of disease manifesting. However, in old age, when vitality declines and climate (referring to physiological energy) wanes, if diet is improper, the qi of the stone will overpower the person's healthy qi, leading inevitably to the onset of disease. Observing both gains and losses, nothing is more evident than this. When young, even without consuming meat, blood and qi remain naturally strong; when old and weak, even with a fine diet including meat, health cannot be maintained. Thus, it is clear that ancient methods had omissions.
Generally, the blood vessels and meridians of the human body should flow continuously. If there is slight stagnation in the blood vessels, sores or fever may arise at the site of stagnation, accompanied by mental confusion and oppression. To prevent this, one should take one or two cups of warm clear wine every morning and evening to promote circulation. Therefore, regulation is not necessary only when deviating from the proper season. It is now observed that those who regulate themselves properly do not suffer from disease onset. Furthermore, renowned physicians advise that those taking stones should often use cooling methods for regulation. If symptoms arise, adjustment becomes easier. If the stone qi activates, temporary venting is required; taking a small amount of cold-natured medicine facilitates excretion. Once unobstructed, the heat is eliminated. However, if one constantly uses cold methods for regulation, when the stone qi activates, cold medicines cannot effectively induce excretion. The principles mentioned here are preserved to broaden understanding and demonstrate how to regulate the body. One must always assess one's own constitution, using cold and heat as indicators, striving for stability. One should not rigidly adhere to theories about stones while ignoring one's own condition and following others blindly. It is hoped that wise gentlemen will pay attention to this.
