Preservation is not difficult.

Fresh yam is easily oxidized by oxygen in the air and turns brown when it comes into contact with iron or metal.

Incision is easy to oxidize, so you can soak it in rice wine first, then blow dry it with a hair dryer to promote wound healing, then wrap it in a napkin, wrap several layers of newspapers around it and put it in a cool corner.

Yam is also called yam, sweet potato and yam. According to Compendium of Materia Medica, yam is warm, sweet and non-toxic, beneficial to kidney qi, strengthening bones and muscles, strengthening spleen and stomach, stopping diarrhea, resolving phlegm and promoting fluid production, moistening fur, and treating nocturnal emission and amnesia. It is an excellent health food and Chinese herbal medicine, and has been widely used as a medicinal tonic in Southeast Asia since ancient times.
