Embodiment 1

[0009] prescription:

[0010] Clove leaves 140g

[0011] Macrogol 4000 30g

[0012] A total of 1000 pills were made, each weighing 50 mg.

[0013] Preparation method: Take 140g of clove leaves, add water (12 times the amount for the first time, 8 times the amount for the second time) and decoct twice, the first time is 2 hours, and the second time is 1 hour. The extracts were combined and filtered, and the filtrate was concentrated under reduced pressure to a relative density of 1.10-1.12 (60°C thermal measurement), spray-dried to obtain a dried medicinal powder, which was added to polyethylene glycol 4000 melted at 85°C, and stirred evenly. The selected dripper with the inner and outer diameter of the drop opening is 3.2 / 5.8 (mm / mm), and the drop distance is 5cm. Drop into methyl silicone oil at 15-20°C at a rate of 30d / min and shrink into pellets, sieve and wipe dry to obtain.

Embodiment 2

[0015] prescription:

[0016] Clove leaves 140g

[0017] Macrogol 6000 30g

[0018] A total of 1000 pills were made, each weighing 50 mg.

[0019] Preparation method: Take 140g clove leaves, add water (12 times the amount for the first time, 8 times the amount for the second time) and decoct twice, the first time is 2 hours, and the second time is 1 hour. The extracts were combined and filtered, and the filtrate was concentrated under reduced pressure to a relative density of 1.10-1.12 (60°C thermal measurement), spray-dried to obtain a dried medicinal powder, which was added to polyethylene glycol 6000 melted at 90°C, and stirred evenly. The selected dripper with the inner and outer diameter of the drop opening is 3.2 / 5.8 (mm / mm), and the drop distance is 4cm. Drop into methyl silicone oil at 15-20°C at a rate of 30d / min to shrink into pellets, sieve, and dry to obtain.

Embodiment 3

[0021] prescription:

[0022] Clove leaves 140g

[0023] Macrogol 4000 15g
