香烟对人体的有害成份主要是烟碱(尼古丁),焦油(主要是8、4苯并芘),一氧化碳,致咳质等。为了寻找出能降低香烟中上述有害成分的药物,以减轻对人体的危害,我们于1981年3月至1982年12月,从多种中草药中筛选出有镇咳、祛痰、平喘作用的芒果叶,通过实验研究及临床观察,试制成掺入1.4%芒果叶浸膏的香烟(简称试制烟),经中国烟草工业科学研究所作烟雾测定,证明其所含烟碱及焦油都比对照烟低。现将实验研究及临床观察结果报导如下。 The harmful components of cigarettes to the human body are mainly nicotine (nicotine), tar (mainly 8- and 4-benzopyrene), carbon monoxide, and cough quality. In order to find drugs that can reduce the above-mentioned harmful components in cigarettes to reduce the harm to the human body, we selected antitussive, expectorant and antiasthmatic effects from various Chinese herbal medicines from March 1981 to December 1982. The mango leaf was experimentally studied and clinically observed to be tested as a cigarette mixed with 1.4% mango leaf extract (referred to as trial-produced tobacco). The smoke of scientific research conducted by the Chinese tobacco industry proved that the content of nicotine and tar contained in the mango leaf was higher than that of the control. Smoke is low. Experimental studies and clinical observations are reported below.
