Know that eating one food immediately after another food and the wrong sequence of its types is one of the most harmful things for the liver; drinking cold water on an empty stomach in one breath, after a bath, after copulation or after physical exercise often leads to a strong cooling of the liver, because the heated liver quickly and abundantly absorbs it; sometimes it is. leads to dropsy. Under such circumstances, you should mix water with wine, do not cool it too much and do not drink it in one gulp, but, on the contrary, draw it little by little. All viscous substances are harmful to the liver in that they cause blockages. Wheat is one of the substances that is viscous in comparison with the liver, while it does not have this property in comparison with the organs into which it enters after the liver, after being digested in the liver. Not all wheat is like this, only sticky wheat.
Sweet wine causes blockages in the liver, while the same wine removes the juices in the chest. The reason for this is that sweet wine is not drawn into the liver gradually, but immediately, for such wine is kind to the liver, because it is sweet, and quickly penetrates the body, because it is wine. It does not linger in the stomach so much that a sediment is separated from it, as other thick things are retained, but enters the liver, retaining its thickness and finds a passage into it prepared for itself, for the paths between the stomach and the liver are wide in comparison with the blood vessels leading to the liver and dispersed in it. Once in the liver, the wine does not stay there long enough to decompose into its constituent substances and be digested; on the contrary, its liquid part rushes through the narrow hepatic vessels, as it quickly penetrates them, and the sediment remains in the liver due to the narrowness of the passage. But in the lungs the opposite happens. Sweet wine enters there after it has already been purified, either through the passages of the esophagus, leaking from narrow passages into wide ones, or through the vena cava, leaving sediment in the space adjacent to it, and is pure; pouring out through narrow passages into wider ones, it is purified once again. The same applies to other qualities of the liver, which it does not have in comparison with the lungs.
