Therapeutic significance of Saptamrita Lauha in ayurvedic ophthalmology: a review
##plugins.themes.academic_pro.article.main##
Abstract
Saptamrita Lauha is a classical herbo-mineral formulation widely described in Ayurvedic literature and traditionally indicated in the management of Netraroga along with various systemic disorders such as Pandu, Shula, and Amlapitta. The formulation consists of Yashtimadhu, Triphala (Amalaki, Haritaki, Vibhitaki), and Lauha Bhasma, administered with Madhu and Ghrita as adjuvants. These ingredients collectively exhibit Tridoshahara, Rasayana, and Chakshushya properties, contributing to ocular nourishment, enhancement of visual function, and correction of underlying Dosha and Dhatu imbalance. A comprehensive review of classical texts and standard Ayurvedic references reveals that the synergistic pharmacodynamic actions of the formulation support its effectiveness in ocular disorders and associated systemic conditions. The fine processing of Lauha Bhasma enhances bioavailability, while Madhu and Ghrita act as Yogavahi, facilitating deeper tissue penetration and improved therapeutic efficacy. Although Saptamrita Lauha has been extensively used in clinical practice since ancient times, scientific validation through standardization, pharmacological evaluation, and well-designed clinical studies is necessary to establish its safety and efficacy in contemporary Ayurvedic and integrative ophthalmic care.
