Looking up some information, we will find that the so-called "fried rice in the mountains" is actually the southern candle, also known as the king of vegetation, dyed glutinous rice, green fine grass, cattail grass, black rice grass, black rice grass and Vaccinium bracteatum. It originally belonged to Ericaceae, but now it belongs to the newly independent Vaccinium bracteatum family, and its original plant is Vaccinium bracteatum. The ancient name of Southern Candle is Dyed Osmunda, because its branches and leaves have the function of dyeing, and its fruit is like beans, hence the name. The sound of dyeing is called southern candle.
Southern candle (green essence) is a very famous plant in cultural history. "What is all in the mountains? There are many white clouds on the hills. I can only be self-satisfied, and I can't bear to give it to you. " The author of this poem is Tao Hongjing, a pharmacologist of the Liang Dynasty in the Southern Dynasties, who is known as the "Prime Minister in the Mountain". In his Taoist book "Dengzhen Yinji", he introduced the practice of "green rice": "Boil the juice and stain the rice in the south candle grass". In the Tang Dynasty, the custom of eating black rice prevailed, and Du Fu's poem "Give Li Bai" included "Two years as a guest in the east, and he was tired of being clever. Savages are often not satisfied with meat and vegetables. Is there no green rice that makes my color good ... ". In the Tang Dynasty, Lu Guimeng's poem "On April 15 th, the Taoist priest sent a letter to the United States" said: "The new cooking of black rice is delicious, and the Taoist priest takes it for granted." The Tang Dynasty Chen Zang-qi's Collection of Materia Medica records the method of making refined rice at that time: "Take the stems and leaves of Nanzhuang, mash them, soak them in pickled juice, steam them for nine times, and expose them for nine times. The rice grains are tight and small, black as pearls, and the bags can be suitable for the distance." In the Song Dynasty, Lin Hong's "Mountain Family Clear Confessions" said: "Herbal southern candle, today's ink rice grass, that is, green essence." Li Shizhen's Compendium of Materia Medica once recorded: "There are many southern candles in Wuchushan, and the leaves are like mountain alum, which are smooth and sour. Small white flowers bloom in July, and they are as strong as clusters of Pu Shu seeds, which are green and ripe in September, then purple, with fine seeds inside, which are sweet and sour for children to eat." Black rice "is the method used by the immortals to eat, but today, more Buddhist people make it on April 8 to offer it to the Buddha's ears." In some ancient books, Nandina domestica was mistaken for Nandina domestica, such as "Illustration and Materia Medica" in the Song Dynasty and Shen Kuo's works in the Song Dynasty. Today, people think that Nandina domestica and Nandina domestica are two kinds of plants, and Nandina domestica is a Vaccinium bracteatum, that is, a green tree.
