One gram of saffron in 20 yuan is not genuine, mainly because the planting cost of saffron is high and the market supply is relatively small, which leads to its high price. The price of high-quality varieties can reach more than 0/00 yuan per gram/kloc. Therefore, the price of only one gram of saffron in 20 yuan is not genuine, and unscrupulous traders will use grass saffron as fake saffron to lower the price and attract consumers.

When buying saffron, consumers need to choose regular pharmacies and websites to buy it, and pay attention to the comparison and identification with reference to market price information to ensure that what they buy is genuine.
