Apium graveolens is used as a Homeopathic or used simply as a micro-nutritional (animal extract). 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, Apium graveolens has demonstrated effectiveness against the following symptomology: Headache, throbbing headaches by the slightest motion, fidgeting, unable to remain still, heartburn, otorrhoea, Postnasal catarrh, rumination, urinary problems; retention of urine.
