On the subtlety of "barbituric acid"
Between heaven and earth, creation is miraculous, things have their own properties, and medicines have their uses. Today, on barbituric acid, this is the subtlety of medicine.

Barbituric acid is a wonder of chemistry. Its structure is unique, just like the wonderful strokes of nature. It is cleverly combined with carbon, hydrogen, oxygen, and nitrogen elements, like stars arranged on rails, to form this unique shape. Its shape is either powder, delicate like dust, shiny under light, or crystalline, clear like ice, showing pure quality.

Its mild nature contains agility. On the stage of chemical reactions, it is like a dancer, moving according to the law. In case of alkali, it is like a confidant, and it blends with it to form salts, just like the music and music, playing a unique song. Its dissolving nature seems to be attached to water, although it is not completely integrated, it can also show some intimacy. In alcohols, it is more affinity, leisurely dispersed, and integrated.

As for pharmacological uses, barbituric acid is like a sharp blade in the hands of a doctor. It acts on the domain of nerves, just like the breeze caressing the forest, making the branches and leaves of excitement gradually calm down. It can slow people's impatience, calm people's souls, and help them sleep. If a person is upset, tossing and turning, it is difficult to sleep, so he can take it in moderation, as if the night is gently shrouded, the body and mind gradually enter a state of silence, and the road to sleep quietly opens.

However, the way to use medicine is like walking on thin ice. Although barbituric acid has the ability to help the world, overdose is like a runaway horse, which disrupts the order of the body. The central nervous system is tired by it, or it may be unconscious, and the breath of breathing is also fettered, which is full of danger. Therefore, when a doctor uses it, he must weigh the advantages and disadvantages, and act prudently, so that he can use its advantages to avoid its harm, so that this delicate thing can benefit the well-being of mankind and shine forever in the glory of medicine.
