The fruit of bergamot has several longitudinal cracks, which are shaped like the palm of a Buddhist, hence the name, but what kind of plant is this? Judging from the flower morphology and leaf morphology at flowering stage, it is undoubtedly a plant of Rutaceae and Citrus. Its taxonomic status should be a variety of citrus. A remarkable difference between this citrus and other citrus is that the petiole of citrus has no wings, while the petiole of other citrus has wide wings or narrow wings. In addition, the petiole of citron intersects with leaves without joints, while other species have joints. A bergamot is a "bergamot" when its fruit splits like a palm or even opens like a finger. Bergamot is also known as bergamot, Fushou Citrus, Finger Citrus and so on. It originated in China, probably in the late Yuan and early Ming dynasties. As an ornamental plant, bergamot has been planted in Jiangsu, Zhejiang, Guangdong, Sichuan, Fuzhou and other provinces in China, and its reputation has never declined. Because Buddha and blessing are homophonic, I believe how lucky I am to repair it. In the 40th episode of A Dream of Red Mansions, we can find that in Tanchun's room, there is a red sandalwood shelf with a big plate on it, and there are several big Buddha hands in it as a clear confession. Explain that people respected bergamot at that time and regarded him as an auspicious thing. According to folklore, there once lived a mother and son at the foot of the mountain. Mother is ill and her breasts are often full. Her son went to see a doctor, but many doctors couldn't cure the disease. One night, his son dreamed that a fairy came down and told him that there was fruit on a tree on the mountain, which was rich in fragrance. Let your mother smell the fragrance and treat it. After the son woke up, he climbed up the mountain to find the tree according to the fairy's instructions, and he found it, but he saw that the tree was full of delicious fruits, and he was full of joy. He picked a few to let his mother smell its fragrance. After a few days, he actually recovered. People think that the immortal must be Guanyin Bodhisattva, so they call this fruit "bergamot". According to the cloud, bergamot was first listed in "Southern Yunnan Materia Medica", which has the functions of "nourishing liver and warming stomach, stopping vomiting, dispelling cold and relieving pain, and regulating qi". Modern pharmacological research has proved that bergamot has the functions of inhibiting gastrointestinal smooth muscle, relieving spasm and anticonvulsant.
