The invention belongs to the field of preparation of health care tobaccos, and particularly relates to a preparation method of a 
fungus health care tobacco capable of clearing away 
lung heat. Three kinds of extracting solutions are sprayed in the yellowing stage, the color fixing stage and the killing-out stage of 
flue-cured tobaccos. The method specifically comprises the steps that in the yellowing stage of the 
flue-cured tobaccos, when leaves are withered and collapsed, the extracting solution A is sprayed, wherein wild portobello, 
straw mushrooms, 
hericium erinaceus, 
agaricus bisporus, phoenix mushrooms and 
morchella vulgaris are taken as raw materials of the extracting solution A; when the color fixing stage of the 
flue-cured tobaccos begins, the extracting solution B is sprayed, wherein 
tendril-leaved fritillary bulbs, loquat, 
semen coicis, 
water chestnuts, 
lotus seeds, mung beans, 
lilium brownie and 
siraitia grosvenorii are taken as raw materials of the extracting solution B; when the killing-out stage of the tobaccos begins, the extracting solution C is sprayed, wherein oolong tea leaves, 
lotus leaves, boxthorn leaves, mulberry leaves, 
oldenlandia diffusa, sculellaria barbata and 
honeysuckle stems are taken as raw materials of the extracting solution C. In the 
manufacturing technology of the cured tobaccos, the extracting solutions capable of clearing away 
lung heat are sprayed to the tobacco leaves in the three stages, and the hurt of tobacco leaves to the health of a 
human body is relieved.
