Gandhaka Druti (गन्धकद्रुति) – An Ayurvedic Sulphur-Based Formulation
🔬 Introduction:
Gandhaka Druti is a classical Ayurvedic preparation where Shuddha Gandhaka (Purified Sulphur) is dissolved or melted into a base liquid—usually a sneha drava (fat medium) or alkaline medium—to enhance its absorption and therapeutic action.
It is mainly used for:
-
Skin disorders (Kushta)
-
Wound healing (Vrana Ropana)
-
Antimicrobial and antifungal action
-
Chronic ulcers, eczema, psoriasis
📜 Reference & Source:
While Gandhaka Druti is not found as a named formulation in Bṛhat-trayī, its preparation is often derived from Rasa Shastra texts like:
-
Rasa Tarangini
-
Rasa Ratna Samuccaya
-
Ayurveda Sara Sangraha
