text: Yo, check it out, listen up, I got something to say,
  'Bout Polygonum multiflorum, used in East Asia every day,
  They say it treats diseases tied to aging, that's the claim,
  But toxicity concerns got people questioning its fame.
  
  Reports talk about liver reactions, they can't be ignored,
  Overdose or the herb itself, the truth needs to be explored,
  So we studied different extractions, components, and more,
  In zebrafish embryos, toxicity was the score.
  
  First, we looked at the solvent used for extraction,
  To see how it affects the herb's toxic reaction,
  And turns out, the 70% EtOH extract took the lead,
  With higher toxicity levels, that's what we agreed.
  
  Next, we took that extract and ran it through a resin,
  Eluting with water and EtOH, man, the process was driven,
  Four components we obtained, let's call 'em A to D,
  And component D stood out, it had the toxicity.
  
  So we focused our attention on that special compound,
  Studied its chemical constituents, we were spellbound,
  Found 27 compounds in total, each with its own name,
  Anthraquinones, stilbenes, anthrones, it was a game.
  
  But hold up, compounds 1 to 3, 16 to 22, and 26 to 27,
  They showed severe toxicity, a threat to zebrafish heaven,
  On the other hand, stilbenes didn't cause no harm,
  No obvious toxicity, they were as cool as a calm.
  
  So there you have it, the study's conclusion,
  Toxicity of Polygonum multiflorum causing confusion,
  It's all about the extraction, the components, and the compounds,
  Zebrafish embryos revealing the truth, no room for doubts.
