They are considered less valuable than the one that has blackish mud in its wrinkles circle. The price difference between them is about 5-10%.
When fresh ginseng roots were stacked together for too long if the temperature is above 40°F, the white inner color could turn to grayish-yellow or reddish-yellow, or even worse: molded. For this reason, cleaning and drying of your freshly harvested wild ginseng in time are very important to ensure its quality and value.
Precautions: Stacking the fresh roots for prolonged periods of time, as shown in the photo below, will result in the spongy inner becoming moldy, yellow-pink, smells bad, and unusable.
When cleaning the wild ginseng, do not place them in running water. Instead, we suggest to soak and wash them. Soaking in water for 5-10 seconds each time, repeated the process for 3-4 times in order to gently remove the dirt.

Running water cleaning will decrease the active ingredient from the surface, and also wipe out too much blackish mud color from the skin. As we know, the black color mud in the wrinkles is very important factor in determining the age of wild ginseng. Excessive rinse will make the surface appears so white that looks like non-wild ginseng.
At the same time, insufficient cleaning should also be avoided as excess amounts of black mud covered on ginseng roots will also result in a decrease in the purchasing price.
The picture below shows unwashed or insufficient washed wild ginseng. There is still a large amount of dark mud left. This will affect the purchase price.
