Abstract
Kushta
, the finest powder compound in Unani herbo-mineral formulations, is prepared from purified metals and minerals through calcination (
Taklīs
). This process, historically rooted in Arabic alchemy, is theorized to convert raw materials into biocompatible oxides and nanoparticles, thereby reducing toxicity and enhancing absorption, bioavailability, and therapeutic efficacy. The final product exhibits the smallest particle size among Unani dosage forms, often forming nanoparticles, which contributes to its quick assimilation and high efficiency. This review aimed to provide a detailed and comprehensive overview of Unani herbo-mineral formulations, concentrating specifically on
Kushta Gaodantī
, its formulations, indications, and available biological research. Data related to
Kushta
was compiled from Unani texts and journal articles, while updated research findings on
Kushta Gaodantī
were gathered from electronic databases such as PubMed, Google Scholar, ResearchGate, and ScienceDirect.
Kushta Gaodantī
is made from calcined, purified gypsum. Conventionally, it is prescribed for fevers (
Ḥummā
), headaches (
Sudā‘
), rheumatism (
Waj‘ al Mafāṣil
), gout (
Niqris
), and ulcers (
Qurūḥ
). Modern quality control studies using techniques such as X-ray diffraction and scanning electron microscopy have confirmed the material’s phase change and the reduction of its particle size to the nanometer range. Moreover, biological research substantiates its traditional uses, showing notable antipyretic, anti-inflammatory, antibacterial, and anti-ulcer properties in experimental models. Furthermore, toxicity studies confirm trace elements are within acceptable limits. Despite evidence of its effectiveness, including in multi-drug regimens for rheumatoid arthritis, the comprehensive validation of its therapeutic efficacy still awaits direct, standalone scientific validation from large, double-blind, randomized controlled clinical trials.
