Snow clam, called Northeast Forest Frog, short Forest Frog. A valuable amphibian growing in the north-eastern forests of China, with snow clams growing in the peri-urban areas of Little Hing Qing, feeding on living insects who have been able to sleep for five months in cold winter, the wonder of what has become known as snow clams is their unique growth environment and resilience. The long, harsh winter and cold natural environment in the north-east has longed for the strength of snow clams, so they are called the “cap of life” of nature. Every fall comes when the snow clams store their energy for hibernation, and when the snow clams are the most alive, especially when the female ovarian tubs (the ointment of snow or forest frog oil) gather together all the nutrients of the next generation, and when the snow clams are more resilient. The efficacy of snow clams as pigment supplements is well known, the taste of which is salty and dry, and contains large amounts of proteins, amino acids and a variety of trace animal polyazine substances, which are particularly suitable for daily supplementation. Snow toad oil is also called forest frog oil, as recorded in this grass. From Ming Dynasty, he was classified as one of the four mountain Janes (Hong Dynasty, Forest Frog, Flying Dragon, Monkey Head) as a tribute from Chiang Dynasty. Snow clams are different in different areas, the Cantonese are called snow clams, while in the north-east they are called toad oils, and the ointments and oils in the anointed and forest frog oils are removed, except for what we call them today. The snow clams we eat and the medicine we use are either whole forest frogs or, in fact, female toads. The stem of the fallopian tube in the female clams, commonly known as forest frog oil, snow toad oil, has been in our history for thousands of years, and the era of clarity has been classified as a tribute to the palace and medically known as soft gold and animal gin. The most common snow clams in the market are snow clams with thaw oil, hysteres, net oils (crumbs), which differ mainly in the way they are processed and in the way they look when they are finished. They are essentially the ovarian tissue of snow clams, with no difference in composition and effectiveness。
