Embodiment 1

[0049] Embodiment 1: (200 dosage)

[0050] Get 0.3g of 1,8-cineole in the volatile oil of waxberry leaves, 0.7g of flavonoid aglycone extracted from waxberry leaves, 1g of lactose, 3g of polyethyl alcohol 4000, 3g of polyethyl alcohol 6000, and 0.06g of polysorbate-80; Mix the main ingredient and lactose evenly according to the method of equal amount addition to obtain (a), and take another prescription amount of polyethylene glycol 4000 and 6000 and heat and melt in a water bath at 100°C to obtain (b); add (a) to (b), and add polysorbate-80, stir evenly, move into the liquid storage bottle of the dropping pill instrument that is kept warm to 57 ℃, after the temperature is constant, control the temperature of the dripper to 40~45 ℃ and drip at a speed of 60 pills per minute to In the glass column of liquid paraffin, filter to obtain drop pills, absorb and dry with talc powder, and each drop pill weighs about 40.0 mg.

Embodiment 2

[0052] Take 0.5 g of 1,8-cineole and flavonoid aglycone extracted from the leaves of Waxweed, 100 g of sodium stearate, and 25 g of insect wax, mix and heat to 100° C. to melt them all. When dripping, use 1% sulfuric acid aqueous solution as the condensate. Keep the medicine solution at 65°C and drop out from the mouth of the dropper. The molten liquid of the main drug and the matrix is ​​dripped into the condensate from the lower part of the condensate, and about 200 drop pills are dripped out per minute from each dropper. The pills slowly drip out from the drop opening and float up, condense while rising, filter out the dripping pills, immerse in cold water to remove the attached acid, then place them on a tray with absorbent paper and roll them. Absorb the water traces on the surface of the pills to obtain the product (the inner diameter of the dropper is 4.9mm, and the outer diameter is 8.04mm).

Embodiment 3

[0054] Get 1,8-cineole 0.5g, flavonoid aglycone 1g, sodium stearate 150g polyethylene glycol 4000 7g lactose 2g extracted in the waxberry leaf, and the method described in Example 1 is used to obtain the present invention. The anti-cold medicine Shanxueye Dropping Pills.
