Oviductus Ranae is a precious frog species, which grows in Changbai Mountain forest area in northeast China. Because it hibernates in the snow for more than 100 days in winter, it is called oviductus ranae. It is this cold tolerance that gives China Rana chensinensis super vitality and special efficacy. Only the oviductus ranae produced in Changbai Mountain in the northeast of Jilin Province is genuine. And those who produce and breed in other places have greatly reduced their nutrition.
