Lac vaccinum defloratum, which is more commonly called skimmed milk, is used as a Homeopathic medicine (animal 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, Lac vaccinum defloratum has demonstrated effectiveness against the following symptomology: a remedy for diseases with faulty nutrition; -constipation (Boericke) -great lassitude and disinclination to exertion; -feels completely tired out and exhausted whether does anything or not; great fatigue from walking; sleepy all day long (Clarke)
