Medicinal Plants
Devil's walking stick, a spiny native tree many gardeners yank out as a nuisance, has been used for centuries by Lisu and Korean communities to treat coughs and breathing problems — and now lab science is beginning to confirm why.
Researchers extracted sugar-based compounds from the Aralia elata plant and tested them on mice with asthma. The compounds calmed the immune system's overreaction, reduced the thick mucus that clogs airways, and brought inflammation levels back toward normal. The effect worked through several immune pathways at once, which helps explain why traditional healers found this plant useful for breathing problems.
Key Findings
59 active compounds were identified in Aralia elata extract, with 10 identified as core anti-asthma components; compound GA52 showed particularly strong binding to two key asthma targets (binding energies of -10.5 and -10.6 kcal/mol).
Treatment significantly reduced 13 inflammatory markers in lung fluid (including IL-4, IL-5, IL-13, IL-17A) and lowered airway mucus protein MUC5AC in both mouse lungs and lab-grown human airway cells.
Transcriptome analysis identified 1,358 differentially expressed genes between untreated and treated asthmatic mice, with significant enrichment in the NF-κB signaling pathway — a major inflammation control switch.

Aralia spinosa, commonly known as devil's walking stick, is a woody species of plant in the genus Aralia of the family Araliaceae. It is native to eastern North America. The various names refer to the viciously sharp, spiny stems, petioles and even leaf midribs. It has also been known as Angelica-tree.
