Question: What if Sergievskaya Zhemchuzhina doesn't feel good? Should I keep drinking water? I drink only water and my head becomes cast iron. Merzlyakova E.M. (April 22, 2020): She also works with capillaries. And I don’t know in what volume you drink this “Sergius Pearl”, for what purpose .... And, look, it opens the capillaries, the arteries that go to the head open best, and the veins that go between the bones - at the back of the neck open the worst. And if you drink Sergievskaya Zhemchuzhina, then the capillary arterial system increases, that is, the pipe that leads water into the pool, you increase its lumen, and the veins are clamped simply by chondrosis, displacement, hernia, and it turns out that the pipe that brings water out of the pool remains the same, there will be a heavy head. Stop, work the neck first..
