The rocks in Jiaodong, Shandong Province are rich in trace elements such as iron, milk calcium, zinc and selenium, so the medicinal value of Yulingzhi is higher than that of Ganoderma lucidum in a broad sense.
Due to the limited growth environment, the growth period is longer than that of ordinary ganoderma lucidum, and it usually takes about ten years to become a strain.
At present, there is no successful record of artificial cultivation. At present, Ganoderma lucidum on the market is wild and cultivated artificially. This is why the price of Ganoderma lucidum is so high.
