Rhus Toxicodendron
Toxicodendron pubescens — Poison ivy
The "rusty gate" remedy — stiffness that loosens with continued motion; the classic remedy for arthritis and sprains.
Overview
Rhus Toxicodendron, prepared from poison ivy, is the great remedy of the "rusty gate" — stiffness and pain on first motion that gradually eases with continued movement. The patient is better from walking but worse from prolonged rest. This makes Rhus Tox the premier remedy for arthritis, sprains, strains, and the soreness of overexertion.
Rhus Tox people are restless — they cannot find a comfortable position and constantly shift, which actually helps their pain. They are worse in cold, damp weather (imagine the stiffness of a rainy morning) and better from a hot bath or warm applications.

Frequently Asked Questions
Rhus Tox or Bryonia — which to choose for joint pain?
Rhus Tox: better from motion, worse from rest, restless. Bryonia: worse from any motion, better lying still, irritable when moved. If walking eases the pain, think Rhus Tox. If any movement worsens it, think Bryonia. They are almost opposite in modalities.
Can Rhus Tox cure poison ivy rash?
Yes — Rhus Tox 30C taken orally (not applied topically) often resolves poison ivy rash within 24–48 hours by using the "like cures like" principle. This is one of the classic confirmations that led Hahnemann and early homeopaths to trust the homeopathic method.
