Petroleum, also known as crude rock oil, is used as a Micro-Nutritional Homeopathic potency (mineral product). 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, petroleum has demonstrated effectiveness against the following symptomology: helps rebalance and drain the body of toxins, skin eruptions, chronic diarrhoea, gastric and cutaneous eruptions, stuous diathesis, especially the dark type.
