St. John's Wort works by regulating the level of neurotransmitter. The active ingredients in St. John's Wort mainly include hyperoxin, pseudohyperoxin, and hyperforin. They can increase the level of major neurotransmitter by maintaining the circulation, thus playing an anti-depression role. Specifically, St. John's Wort could increase the concentration of a variety of monamine neurotransmitter, including 5-ht, norepinephrin, and Dopamine. In addition, St. John's Wort also contains flavanoids, which can increase the level of neurotransmitter in the brain that maintains normal mood and emotional stability. However, the mechanism of action of St. John's Wort was not completely clear and further research was needed.

Stopping the use of St. John's Wort may cause withdrawal reactions, including headaches, fatigue, nausea, anxiety, and insomnia. These symptoms usually appear within one to two weeks after stopping the drug and gradually disappear within a few weeks.

I can't provide any books on the reaction of names. The name reaction was a complex reaction in organic chemistry that involved many different reaction conditions and catalyst selection. It required in-depth understanding and research. If you are interested in organic chemistry, it is recommended to read some classic textbooks or academic journals such as " organic chemistry " and " organic synthetic chemistry ". In addition, you can further deepen your understanding of organic chemistry by participating in online courses or laboratory studies.

In Qing Yu Nian's original work, the secret underwater was the forbidden door at the bottom of Taiping Courtyard's lake. In her letter to Fan Xian, Ye Qingmei mentioned that there was a forbidden door at the bottom of the lake. It was also the final location of all secrets. Taiping Courtyard was the place where Ye Qingmei had once lived. It was also the place where she, the Qing Emperor, Chen Pingping, Fan Jian, and the others had been carefree when they were young.

The Qing Yu Nian underwater mechanism was a forbidden door. It was located at the bottom of the pond in Taiping Courtyard. This mechanism could be opened through the box Ye Qingmei had left for Fan Xian. However, Ye Qingmei had mentioned in the letter that there was danger behind the forbidden door and did not want Fan Xian to search for it. As for what secrets the Forbidden Door hid, the current information did not mention it.

The Qing Yu Nian underwater mechanism was the forbidden door at the bottom of Taiping Courtyard's lake. According to the contents of Ye Qingmei's letter to Fan Xian, this mechanism could be a teleportation door to the Temple, or an armory or laboratory. As for the specific secrets hidden in the mechanism, the current information did not mention it. Therefore, the search results did not provide a clear answer to the specific content and functions of the underwater mechanism.
