text: Yo, check it out, we got a study in the house,
  Tryna determine the effect, no doubt,
  Of casticin, an anti-inflammatory agent,
  On lung inflammation caused by cigarette smoke, blatant.
  
  Casticin, a phytochemical, straight from Vitex species,
  Rotundifolia and agnus-castus, holdin' the keys,
  Recent research showed its anti-inflammatory might,
  Now we 'bout to show you the results, so hold tight.
  
  C57BL/6 mice, two weeks of exposure,
  To mainstream CS, or fresh air, disclosure,
  1, 2, and 10mg/kg casticin, injected in the veins,
  Let's see how it affects the immune cells and the pain.
  
  Bronchoalveolar lavage Fluid, we checked it all,
  Infiltrations and cytokines, ready to brawl,
  Casticin came through, inhibiting cell counts,
  Neutrophils, macrophages, lymphocytes, it amounts.
  
  Proinflammatory cytokines, chemokines, they decrease,
  In the BALF, casticin brings some peace,
  Peribronchial and perivascular cells, they retreat,
  Epithelium thickness reduced, it's a feat.
  
  This study's got the scoop, casticin's the key,
  Fighting lung inflammation caused by CS, you see,
  Therapeutic potential, COPD in its sight,
  Casticin's a game-changer, shining so bright.
