Abstract

The concept of biphasic action of medicines has been known in homoeopathy for a long time. It emphasizes that an organism reacts in two ways to a medicine based on the dose, the direction, and how sensitive it is. In modern pharmacology, we see a similar pattern in biphasic dose-response relationships. This includes hormesis, unexpected drug reactions, and how receptors behave. While both disciplines- homoeopathy and pharmacology recognize biphasic phenomena, they are often discussed in isolation. Homoeopathy considers it in terms of vital force and similitude, while pharmacology looks at it through receptor science, dose-response curves, and toxicology. However, there is little research that systematically compares these viewpoints, leaving a gap in understanding how traditional and modern ideas can complement one another. This article aims to explore the biphasic action of medicines as understood in homoeopathy and modern pharmacology and to look at how homoeopathic ideas connect with current pharmacological evidence. Thereby providing a broader scientific context for understanding the dual nature of drug action, moving beyond the narrow focus on “dose and direction” towards a more holistic integration of traditional and modern therapeutic sciences.
