Hello, this is: Ganoderma lucidum, also known as Cladosporidae, is widely distributed all over the world. Ganoderma lucidum is usually parasitic on the wet and withered trunk, and its fruiting body is flat, so it is named Ganoderma lucidum. Its surface usually has circular growth lines, and its overall texture is as hard as wood. Ganoderma lucidum has the effects of clearing away heat and toxic materials, reducing swelling and resolving hard mass, and can be used for treating pharyngolaryngitis, throat and digestive tract tumors. When used as a medicinal material, it is usually harvested in summer and autumn, sliced, dried and preserved. Ganoderma lucidum, which usually grows on Gleditsia sinensis, has the best effect.
