Extended data:
Pharmaceutical experts and old Chinese medicine practitioners have pointed out that Goubao does have medicinal value, but few Chinese medicine practitioners prescribe this medicine in clinic because it cannot be produced in batches. The purchase price of dog treasures formed by natural breeding was almost the same as that of gold, but if the price is outrageous, it can only show that the so-called collection value has been attached.
Experts remind that the average diameter of genuine dog treasures is 1.5 ~ 5 cm, and there are also cases in the market where other things are used as dog treasures to cheat. Friends who don't understand trade and commodities should be careful to collect them, especially those with oversized specifications.
Goubao is a precious medicinal material, which is mostly purchased by biopharmaceuticals and pharmaceutical purchasing departments at or above the prefecture level. When selling, you should go to a pharmaceutical company or related units for appraisal and evaluation.
