Is pine pollen poisonous?

According to the records in Pharmacopoeia of past dynasties, pine pollen is a medicinal and edible pollen variety in China's medical treasure house. As a traditional medicinal material in China, its medicinal and edible history has exceeded thousands of years, and it has been recorded in ancient medical classics. From Shennong Herbal Classic 2400 years ago to China Pharmacopoeia today, it is regarded as a "magic medicine" among the people because of its magical effect. "Shennong Herbal Classic" in Han Dynasty says that "(pine pollen) is sweet and nontoxic, and it is mainly used for treating cold and heat evil in the heart, facilitating urination, eliminating blood stasis and prolonging life after long-term administration"; Tang's "Newly Revised Materia Medica" said that "pine blossoms are yellow and look like cattail pollen. Long-term use will be bodybuilding, treating diseases better than skin, leaves and fat "; "Herbal Yi Yan" in the Song Dynasty said, "The yellow powder on its flowers is called yellow pine. People in the mountains take it in time to make soup, but it can't be stopped for a long time, so it is rarely used to send it away ... yellow pine is like cattail pollen, but it tastes bad. It can cure postpartum fever, headache, cheek pigment, dry mouth and lips, irritability, thirst and drowsiness"; Ming's Compendium of Materia Medica pointed out that "pine flowers are sweet, warm and nontoxic. Moisten the heart and lungs, replenish qi, dispel wind and stop bleeding, and also make wine "; In the Qing Dynasty, Materia Medica from the New affirmed that pollen "manages sores well, but does not scab when wet".

Records of Medicinal Diet in Past Dynasties: As early as the pre-Qin period, Zhou Li recorded that "eating is learning" and made a philosophical exposition on the relationship between diet and diseases, which laid the medical theory of "preventing diseases" in traditional Chinese medicine. Later generations sorted out various versions of herbs for dietotherapy, among which pine pollen was used to make soup, make stuffing, steam cakes and make wine. The book "Shanjia Qing Palace" mentioned the production of "yellow muffins": after pine pollen comes out, collect powder, add rice flour, mix it with water, seal it for a few days, and then make it into a cake shape similar to Gu Long's birthday. This product is not only sweet, but also strong and beneficial. Ming's "Qunfangpu" was born in February and March and is three or four inches long. When it opens, it spreads the ground with a piece of cloth and beats its core. It is called Songhuang, which can dispel wind, stop bleeding and treat dysentery. Mixing sugar (cake) is very fragrant, suitable for fast eating but not lasting. "

Records in literary works of past dynasties: In the long history of thousands of years, pine pollen not only has the legend of "beauty well", but also records that it is a tribute to the emperor every spring. Scholars and poets even take wine as a song to express their feelings and leave immortal poems; In Tang Dynasty, Zhang Qin's "Dressing House" and Liu Yao's "Ji Biao Ji" both wrote that there was a beauty well at the foot of Shuangjiao Mountain in Baizhou of Jin Dynasty. People who have drunk this well water have beautiful homes. The reason is that pine flowers are open all the year round, pollen falls into wells, and people drink well water with pollen to produce effects, so there are many beautiful women. Bai Juyi, a poet in the Tang Dynasty, said: "The empty stomach pine wine is advanced, and Lotte know life has no worries." ; Su Dongpo, a poet in the Song Dynasty, said: "One catty of pine flowers is indispensable, eight or two catties of pollen cannot be fried, five dollars of Sophora japonica flowers and five dollars of apricot flowers, and two catties of white honey are mashed together. After eating or taking a bath, the red and white faces are old." All of them explain the strange and wonderful use of pine pollen from different aspects.
