Rhus toxicodendron, more commonly known as poison ivy, may only be used as a Homeopathic or a simple micro-nutritional (botanical). Homeopathic potencies accredit their strength and efficacy to the electromagnetic signatures of the original substrate; these are scientifically created dilutions and succussions of medicines such that generally not even a molecule of the original substrate or medicine is present in the medicine.

As a Homeopathic or used simply as a micro-nutritional, Rhus toxicodendron has demonstrated effectiveness against the following symptomology: effects fibrous tissue markedly, joints, tendon, sheaths etc., cellulitis and infections, carbuncles, mucous membrane affections and cold fevers. (Boericke)
