Convulsion disease is taiyang-yangming disease, which means a taiyang surface pattern with even more dryness and stiffness of the musculature. So, since there is a good bit of damage to the ying fluids, the pulse may be deep like a â€œpool with very little water in it.â€ Yes, the surface yang is also damaged, which does cause the interior to become cold, but the level of pathology here is of taiyang/the surface, so we are not yet seeing interior cold symptoms. And, since the body is drying out due to the yangming aspects of the pattern, it will tend to first heat up. Slippery pulses point to heating up of the blood, which is in turn heating up fluids. A THF pulse, referring to GLGZT in chapter 2, is a deep slippery R2.
