Ampelopsis trifoliata

     Three-leaf Woodbine – Toxic dermatitis due to vegetable poisons – 30 and 200. Very similar to Rhus poisoning. Desensitizing against Ivy poisoning by the use of ascending doses of the tincture by mouth or by hypodermic injections is recommended by old school authorities, but is not as effective as the homeopathic remedies especially RHUS 30 and 200 and ANACARD., etc.
