The present invention provides a double-effect tablet structure comprising: an outer layer, a hollow substantially circular shape, and an inner layer, which is a substantially circular shape containing an extract of Antrodia camphorata, and the outer layer has a diameter of between 1 and 10 mm. The layer has a particle size of between 0.5 and 8 mm, and the inner layer is coated in the outer layer, and a polyethylene glycol film layer is present between the inner layer and the outer layer and outside the outer layer. Thereby, the two-layer structure can release the extracts of different compositions in stages.本創作提供一種雙效藥錠結構，包含：一外層，呈中空實質圓形，及一內層，為含有牛樟芝萃取物的實質圓形，該外層的直徑介於1~10mm之間，該內層的粒徑介於0.5~8mm之間，該內層被包覆於該外層內，該內層及該外層間，及該外層之外，有聚乙二醇膜層。藉此，雙層結構可以分段釋放不同成分的萃取物。
