In addition to conventional storage methods, Chinese herbal medicine farmers should carefully master the following six storage techniques to ensure the germination rate of medicinal herbs. The drug species must be stored separately from other (tree, vegetable, grain, grass) seeds to avoid mixing. Before storage, the stems, leaves, weeds, soil and other debris should be thoroughly removed. The storage room should be routinely disinfected to prevent contamination of the drug species. "Control water, moisture content of many drug species should be controlled at 8%-9%, general seeds should be controlled at 12%-13%. High moisture, easy to mold. The best temperature of the drug species should be controlled at 10 Around °C, when the temperature is too high, the seed will have a strong breath, which will consume its own stored nutrients and reduce the germination rate.The medicinal species should be applied with a brick-wood mat, which is more than 50cm above the ground, and should not be placed directly on the ground, otherwise it will be easily damped to reduce the germination rate. Should pay attention to ventilation and ventilation, drug types must not be sealed with plastic bags, because the plastic bag is not air-permeable, it is forced to undergo anaerobic respiration, it will produce toxic substances such as alcohol and organic acids, lose germination power. The chemical fertilizers should be stored together, and they must not be smoked and smoked, but they must also be protected against rat and insect bite.

If we want to distinguish between the two types ,we can see from the ingredients that we should pay attention to.
