In the field, you will often see lily-like trumpet-shaped flowers, fresh and innocent, like a girl in her thirties, and then bow her head shyly, showing her charming posture, like a young woman full of worries, and finally become a hard-nosed capsule, soft without flowers, only strong and arrogant, like an independent aunt. Its life is like a mandala from Sanskrit, literally translated as an altar, a gathering place for sages and an auspicious thing of Buddhism. According to Hokkekyo, Datura was planted when the Buddha said it, so Datura flowers are also full of mysterious religious colors.

Datura stramonium is a solanaceae plant. Its hometown is in India. Because of its strong viability, it can be seen in many places now. It is panicum miliaceum in the cold north, and becomes a shrub in the warm south, full of beautiful flowers. Datura stramonium is also planted as an ornamental plant in gardens and courtyards because its flowers are large and beautiful.

Behind the beauty, it is highly toxic. Datura stramonium is poisonous all over the body, especially fruits, especially seeds. In classical novels, you can often see "antiperspirant". Even if you have advanced skills, if you take "antiperspirant", you will fall asleep and lose consciousness. Its main component is Datura flower. In Water Margin, Wu used a bucket of "sweat medicine" wine and even turned over fifteen strong soldiers and horses. Even a hero like Yang Zhi only drank half a ladle and couldn't move. He had to watch Wu Yong and others put the birth outline on the car. In Sun Erniang's black shop, many heroes were cheated by a small "sweat medicine", even Lu, who uprooted weeping willows, was not spared. Modern research shows that scopolamine is contained in Datura stramonium, which can relax muscles and inhibit the nervous system, so it is quite appropriate for the ancients to use it as an antiperspirant. Legend has it that the main component of "Leprosy Powder" used by Hua Tuo is Datura flower. In the Romance of the Three Kingdoms, Hua Tuo scraped the bones to cure poison for Guan Yu, and suggested that Guan Gong use "Leprosy Powder", which was rejected. As a result, Guan Gong underwent surgery while playing chess, which was praised by later generations. However, when Hua Tuo performed craniotomy on Cao Cao with "Ma Feisan", he was killed by suspicious Cao Cao and then lost contact.

In addition to its medicinal value, Datura is also a symbol of love and hate. In Jin Yong's The Condor Heroes, there is a poison called Love Flower. As long as the poisoned person moves his lust, once he misses his beloved, he will be poisoned and miserable. The antidote is desperate Dan or broken grass. There is a saying that the love poison in Jin Yong's works is Datura, which symbolizes missing and inseparable love, and also symbolizes revenge. When Yang Guo and Little Dragon Girl were poisoned by the flower of love in the valley of despair, both sides valued each other's life more than their own, and both asked each other to take the antidote to survive. After sixteen years in the valley of despair, they still remember each other for a long time. What's it like to die? Love flowers are also highly toxic, while the owners of Despair Valley, Gong Sunzhi and Qiu thousands of feet, show their frame-up and revenge. In "Eight Dragons", Li Dui, the owner of the villa, also loves and hates Duan. In western legends, Datura also has a sad love story. A woman is thirsty and dying in the desert. The water god in charge of desert water fell in love with her and told her the location of the water source. When god knows, he will execute the water god. At this time, the Datura flower god, who has been taken care of by the water god, begged God to accept the punishment together. Deeply moved, God exempted the water god from the death penalty, but Datura flower became a poisonous flower.

Datura is "antiperspirant" in the hands of wicked people and "hemp boiling powder" in the hands of doctors. It represents the love that never dies, and it also represents the hatred of revenge. Just like human nature, there are beauty and ugliness, good and evil, maybe only in one thought.
