Dendrobium is a nutritious herb with excellent curative effect. This is a facultative CAM plant. Dendrobium candidum is very active in high temperature and dry environment. Pseudocorms are exposed to sunlight during the day, and after cooling at night, they can absorb water in the air to continue their biological metabolism, which will consume their stored nutrients including Dendrobium polysaccharide, Dendrobium alkaloids and other pharmaceutical ingredients.
If you want to preserve fresh Dendrobium for a long time, the method is still very conventional, that is, put fresh Dendrobium strips in a ventilated place and keep the temperature at 0 to 10 degrees. It is also a good choice to put it on the fresh-keeping layer of the refrigerator. Never pack fresh strip food in vacuum.
