Pulse of different natures

A hot nature needs cooling more, therefore, if strength and weapons contribute, then the pulse is high. If one of these factors counteracts, then the situation is as we explained in detail in the previous one. If the nature is hot not due to a disorder of nature, but naturally, then it is strong and healthy, animal strength is very great. Do not think, however, that an increase in innate heat causes a decrease in animal strength, reaching the same degree as the increase in heat. On the contrary, it arouses strength in the substance of pneuma and ardor in the soul.

As for the warmth that accompanies the disorder of nature, every time its strength increases, animal strength becomes weaker.

As for the cold nature, it deviates the pulse towards insufficiency, especially, for example, towards smallness, slowness and infrequency.

If the weapon is soft, then its width is greater, as well as slow and rare, but if it is hard, then this is not the case. The weakness left by a disorder of a cold nature is greater than the weakness left by a disorder of a hot nature, for a hot nature is closer in similarity to innate warmth.

As for the wet nature, it is accompanied by the undulation of the pulse and its breadth, and the dry nature is accompanied by the narrowness and hardness of the pulse. Then, if the force is great and the "need for cooling" is strong, a two-beat pulse occurs, as well as a spasmodic and tremulous pulse. Then you can combine the types of pulse yourself, keeping in your memory the basics of the doctrine of the pulse.

It happens that the same person has a dissimilar nature of the two halves of his body, so that one half is cold by nature and the other is hot. Therefore, it happens that in such a person the pulses of both halves are dissimilar in relation to the irregularities generated by heat and cold, so that the hot side has the pulse of a hot nature, and the cold side has the pulse of a cold nature. From this we know that the pulse, when it contracts and expands, beats not as a result of the ebb and flow of blood from the heart, but as a result of the expansion and contraction of the body of the artery itself.
