Example Embodiment
[0036] Example 1
[0037] This embodiment provides an orange-red atomized inhaler and a preparation method thereof, which are specifically as follows:
[0038] (1) Take 200g of orange red, add 8 times the amount of water, heat and decoct for 2 hours, and collect the volatile oil and non-volatile extraction products, and filter the non-volatile extraction products to obtain extract A and medicine residue;
[0039] (2) Add 6 times the amount of water to the medicinal residue, heat and decoct for 2 hours, filter to obtain extract B;
[0040] (3) Combine extract A and extract B obtained in steps (1) and (2), recover ethanol and concentrate to an appropriate amount, add ethanol to make the alcohol content 70%, stir well, stand still, take the supernatant to recover Ethanol and concentrating to obtain the orange red extract;
[0041] (4) Take the volatile oil from step (1) and add hydroxypropyl-β-cyclodextrin with an average degree of substitution of 4.5 for inclusion to obtain an inclusion...

[0050] Example 3
[0051] This embodiment provides an orange-red atomized inhaler and a preparation method thereof, which are specifically as follows:
[0052] (1) Take 200g of Huatanghong, add 8 times the amount of water, heat and decoct for 2 hours, collect the volatile oil and non-volatile extraction products, filter the non-volatile extraction products, and obtain extract A and medicine residue;
[0053] (2) Add 6 times the amount of water to the medicinal residue, heat and cook for 2 hours, filter to obtain extract B;
[0054] (3) Combine extract A and extract B obtained in steps (1) and (2), recover ethanol and concentrate to an appropriate amount, add ethanol to make the alcohol content reach 70%, stir well, stand still, take the supernatant to recover Ethanol and concentrating to obtain the orange red extract;
[0055] (4) Take the volatile oil from step (1) and add hydroxypropyl-β-cyclodextrin with an average degree of substitution of 10.0 for inclusion to obtain an inclusion...
