Canaigre Dock

  • The roots of the Canaigre Dock plants are used topically for their astringency[1] capacity. It is also applied to lessen skin irritation and redness caused by burns, rashes, and scrapes.
  • The genus name “Rumex ” means docks and sorrel plants. The species name “hymenosepalus[2] means membranous sepals.
  • The dried roots of the Rumex hymenosepalus contain 35-60 percent tannin[3]. The cultivated roots have less tannin than the wild roots.
  • Scientists were able to synthesize silver nanoparticles using the extract of Rumex hymenosepalus. The research conducted[4] showed these showed inhibitory effects over broad-spectrum microbicidal agents.
  • The anti-tumor compounds, leucodelphinidin and leucopelargonidin have been reported isolated from the Rumex hymenosepalus[5] . .
