By combining examples 1 to 6 with comparative example 1 and table 3, it can be seen that the tobacco liquid has a good degree of harmony and a certain fragrance when the tobacco liquid is smoked after the plant extract is added to the tobacco liquid. After the plant extract is added, the irritation of the smoke liquid is obviously smaller, which indicates that the irritation to the throat is reduced. The reason for this is probably because the folium isatidis contained in the plant extract can relieve sore throat, and has better heat-clearing and detoxifying effects when being matched with honeysuckle. The radix ophiopogonis tuber has the functions of moistening lung, clearing heart fire, reducing phlegm and preventing vomiting, the loquat has the functions of reducing phlegm and relieving cough, and the cassia seed, the folium isatidis and the radix ophiopogonis tuber together enable the tobacco juice to have better throat moistening and cough relieving properties. In addition, during the test, it was found that after 1 month of continuous smoking of the tobacco smoke solution prepared in example 5 (twice daily), the symptoms of cough were relieved and the degree of craving was reduced.

It can be seen by combining examples 1-6 with comparative example 2 and table 3 that the eucalyptus oil can greatly improve the aroma and aftertaste of the tobacco liquid after being added into the tobacco liquid, which indicates that the eucalyptus oil can cover part of the odor of the plant extract, and the odor and the mouthfeel can be better improved after being assisted by the essence. In addition, the eucalyptus oil also has certain functions of moistening the throat and moistening the lung.

Combining examples 1-6 and table 3, it can be seen that the smoke liquid prepared from pre-treated loquat during the preparation of the plant extract has better fragrance and aftertaste, and slightly better irritation. In addition, when the weight ratio of the eucalyptus oil to the plant extract is 1: (2-3), the obtained tobacco liquid has good harmony and good taste. And the weight ratio of the cassia seed, the honeysuckle, the indigowoad leaf, the loquat and the dwarf lilyturf tuber is 1:1.5:2:3: when 0.3 hour, the obtained plant extract has small irritation and good taste when added into tobacco liquid. Comparing example 5 with example 6, it can be seen that the plant extract obtained by supercritical carbon dioxide extraction has less offensive odor, more and purer effective substances, and better taste.

By combining examples 1-6 with comparative example 3 and table 3, it can be seen that after oxygen is introduced during the process of preparing the tobacco juice, the irritation of the tobacco juice is reduced during the smoking process, and the taste of the tobacco juice is improved.
