Problems solved by technology

[0003] At present, the leading product on the market is Guizhi Fuling hard capsules. After the capsule disintegrates, the dissolution rate of active ingredients is slow and incomplete, resulting in poor absorption and insignificant curative effect. In addition, fatty acid active ingredients are easily oxidized, cinnamic acid, cinnamaldehyde, etc. Volatile components are easy to volatilize and disperse, and ordinary powder or granule-filled capsules are difficult to keep such components for a long time, and the stability is not ideal
[0004] Chinese patent application number CN200410051484.9 discloses a cinnamon twig tuckahoe dispersible tablet and its manufacturing method, and CN200410069115.2 discloses a cinnamon twig tuckahoe orally disintegrating tablet and a preparation method thereof, but the preparation of the dispersible tablet and the orally disintegrating tablet The process is relatively complicated, the requirements for auxiliary materials are strict and the cost is high, which is not conducive to large-scale industrial production
