The preparation method of cooked Radix Notoginseng is to cut raw Radix Notoginseng into pieces, soak in salt water, dry in the sun, and grind into fine powder. Some people put raw notoginseng in a small bowl, which is filled with clear water. The amount of water is like this. You can suck the notoginseng dry, then steam it and slice it, fry it until it is yellow, crisp but not burnt, and then grind it into powder to make it mature. Both methods are acceptable.
