The invention discloses a
traditional Chinese medicine composition for clearing
lung, expelling
toxin and preventing
lung cancer after
smoking cessation. The
traditional Chinese medicine composition is prepared from 9-100 parts of
polygonum cuspidatum, 9-100 parts of raw
sanguisorba officinalis, 4.5-9 parts of
houttuynia cordata, 9-30 parts of lily, 10-30 parts of
astragalus membranaceus, 9-30 parts of exocarpium citri rubrum, 6-15 parts of mint and 15-50 parts of raw liquorice. Preferably, 15 parts of
polygonum cuspidatum, 15 parts of raw
sanguisorba officinalis, 15 parts of
houttuynia cordata, 15 parts of lily, 15 parts of
astragalus membranaceus, 12 parts of exocarpium citri rubrum, 9 parts of mint and 9 parts of raw liquorice are adopted. The preparation method comprises the following steps: decocting the medicinal materials with water, concentrating and
drying into
powder. According to the composition, the
lung cancer risk of severe smoking quitters is remarkably reduced by inhibiting
inflammatory factors TNF-alpha to be smaller than or equal to 18.41 + / -4.73 pg / ml, IL-6 to be smaller than or equal to 16.69 + / -3.02 pg / ml, reducing
a DNA damage mark gamma-H2AX to be smaller than or equal to 2.15 + / -0.43
score and reducing an
oxidative stress mark 8-OHdG to be smaller than or equal to 2.19 + / -0.49
score. The
traditional Chinese medicine composition can be prepared into oral preparations such as granules and tablets and has the effects of clearing away lung-heat and detoxifying and supporting healthy energy.
