| Introduction | Pteridium aquilinum, also called punch, cat's claw, dragon's head, deer Pteridium, Pteridium, cat's paw, the lotus is the bud of the ferns. English name: Pteridaceae, belonging to the family Pteridaceae. It is found in the Xiangyang land in the shallow mountain area, and most of them are distributed in the sparse coniferous and broad-leaved mixed forest. It is widely distributed in northwest, north, northeast, southwest and central China. The food records were first recorded in the Book of Songs: "Lupo Nanshan, pick up its ferns". According to the Compendium of Materia Medica, the ferns are sweet and cold in taste, with heat-clearing, bowel-gliding, gas-reducing, wind, phlegm and other effects, the main treatment of food diaphragm, gas diaphragm, intestinal wind heat and other diseases. |
| in vivo & in vitro studies | both in vivo and in vitro studies have shown that, protososide has cellular and genotoxic properties that are directly associated with tumorigenesis in the urinary tract and gastrointestinal tract. At the same time, the Epidemiology study also proved that the population living in areas with dense growth of Ferns was positively related to the risk of gastric cancer death, the incidence of malignancy in adults was more than twice as high in those exposed to protoporphyrin in childhood as in those who did not (OR = 2.34). In addition, the study also found that in addition to direct consumption of Pteridium aquilinum, milk, livestock and poultry meat, and even groundwater contaminated by the original pterins can be affected by the original pterins. At present, the original pteroside is classified as a class 2B carcinogen by the World Cancer Organization, and the content of the original pteroside in the buds of the Ferns is the highest. |
