If there is no bad juice, then we are only changing the bad nature. If there is bad juice, then we perform a bowel movement. Sometimes we limit ourselves to just one emptying, if after it there remains no bad nature that had established itself even earlier. Sometimes emptying is not enough if a bad nature remains after it, so after the emptying is completed, the nature should also be changed.
We say that the treatment of a bad nature is threefold, because: the bad nature may have already taken hold, then it is generally treated with the opposite means, and this is a general treatment, or the bad nature may be on the verge of formation then they correct it with treatment and preventive measures in order to prevent the causes of damage, when the nature is just about to deteriorate, you only need to prevent the cause of this, and then this is called a warning.
An example for the first type of treatment is the treatment of putrid juices during four-day fever with the help of teryak Three-day fever is also treated by drinking cold water to extinguish it. An example for treatment along with prevention is the emptying of the body in case of four-day fever with hellebore, and in case of three-day fever with scammonium, if we want to prevent the onset of an attack. An example for a pure warning is the following: if the human body, as a result of the predominance of black bile in it, is prone to a four-day fever, then we empty it with hellebore, and if, due to the predominance of bile, the body is prone to a three-day fever, we empty it with scammonium.
If with any disease it is difficult for you to determine whether its cause is hot or cold, and if you want to test it experimentally, then under no circumstances do this with the help of extraordinary means Be careful not to be misled by the display results of the action.
Know that the cooling and warming of nature have the same duration, but with cooling there is greater danger, for warmth is a sincere friend of human nature. Both humidification and drying have the same danger, but the duration of humidification is longer. Both moisture and dryness are preserved by the intensification of their causes, and both are changed by the intensification of causes of the opposite quality. Warmth is enhanced by those reasons, the mention of which we have already finished. In addition, it is strengthened with the help of means that stimulate it, namely, shaking out excess and overflow and opening up blockages, then with the help of what retains warmth, namely balanced moisture. Humidity is enhanced by reinforcing its causes, retaining heat and with the help of something that greatly dissolves it, and this is essentially dryness and accidental heat.
Anyone who treats excessive heat by opening blockages must beware of excessive cooling, so as not to increase the petrification of blockages, which in turn will strengthen the bad hot nature. The doctor should be careful and first treat with something that clears away excess. If one cooling and cleansing agent, such as barley water and chicory juice, is enough, then that is good. If, however, this does not satisfy, it is necessary to treat with moderate means, but if this does not satisfy, then they also treat with something that has a weak hot property, and one should not pay attention to this, because in order to cool the nature, these means, by opening up blockages, will bring great results. benefits than harm from the easily extinguished warming that will occur after the blockages are opened.
Excessive refrigeration often prevents hot juices from ripening, although some people insist that this opinion is incorrect. They do not know that extreme cold reduces strength, especially if it is weakened by long illness. Although cooling will properly correct the bad juice, it will cause other diseases: either simply a bad cold nature, or a nature with bad juices, the opposite in their properties to those juices that cooling corrected.
As for warming up a cold nature, it seems difficult if the coldness of the nature is already entrenched but from the very beginning it is extremely easy. In short, warming a cold nature at the beginning of a task is easier than cooling a hot nature at the beginning of a task. However, cooling a hot one at the completion stage, although difficult, is easier than warming a cold one at the completion stage, for the predominance of cold is death for nature or will lead to it.
Know that cooling is sometimes combined with drying, sometimes combined with moistening, and sometimes free of them. Drying more strongly reinforces the cold that has already appeared, and moisturizing more strongly attracts the cold that is just emerging.
All causes of warmth, when they are excessive, contribute to drying, and all causes of cold, when they are excessive, contribute to moistening. Nothing moisturizes more than a calm lifestyle, constant and light bathing in the sauna and bath. We have already said this above. Drinking wine diluted with water also increases hydration.
Know that if old people need to cool and moisten their nature, then it is not enough for them to return it to balance, but their nature should be brought to the same degree of coldness and dampness that they had, for these qualities, although accidental, will be like would be natural.
You should know that when changing any nature, for the most part you need to use something that strengthens this tendency. TURU, mixtures with products of the opposite quality. For example, vinegar should be used along with medicines that warm an organ, so that the latter gives the medicine strength, or, for example, saffron should be used together with cooling medicines for the heart, so that it delivers these medicines to the heart.
For the most part, medicines have a strong effect on changing the nature, but due to their liquid state they cannot linger long enough to exert their effect. Therefore, it is necessary to mix them with a substance that thickens and retains them, although this substance causes the opposite effect of drugs for example, wax and other things are mixed with the balm in order to retain the balm in a given organ for such a time during which it will have its effect.
