Some Constituents of the Poison Ivy Plant (Rhus Toxicodendron)

"Some Constituents of the Poison Ivy Plant (Rhus Toxicodendron)" by William Anderson Syme is a scientific paper from 1906 that explores the chemical makeup of poison ivy and why it's poisonous. The paper digs into the plant’s different parts, like gallic acid, fisetin, and rhamnose, trying to figure out exactly what makes it so irritating. Syme looks at past studies and does experiments to pull out and describe these chemicals, especially focusing on a poisonous tar or gum that causes skin problems. The paper also touches on using potassium permanganate to treat poison ivy rashes. It gives a full picture of poison ivy's chemistry and adds important info to the study of plant-based poisons.
