Barbituric acid alone has a very strong behavioral effect.

When you taste barbituric acid in medicine, the behavioral effect is outstanding. Although there are no other things to support it, its nature is strong, and it has a deep impact on behavior. It may make people in a trance, and their behavior is different from usual; or it may make their mood swing, which cannot be suppressed. When you observe this acid, it is not fake, but the behavior becomes obvious, which is really a wonder of medicinal properties. Its effect on the human body cannot be ignored, and it is used properly, or it is beneficial; if it is lost in its degree, disaster will follow. Therefore, when a doctor uses medicine, he must carefully examine its nature, and be careful to ensure that it is safe.
