Pharmaceutical insights and therapeutic importance of Pottali Kalpana – A literature review

In Rasashastra, various Rasakalpas are described, including four primary types: Kharaliya, Parpati, Kupipakwa, and Pottali Rasakalpas. Each has a unique place in Ayurvedic therapeutics due to its distinctive qualities. While Khalviya, Parpati, and Kupipakwa Rasakalpas are widely used by Vaidyas in their practice, Pottali Kalpas are rarely utilized. The Pottali process involves compacting scattered materials into a cohesive form, such as Hemagarbha Pottali, Lohagarbha Pottali, and Tamragarbha Pottali. This technique involves treating the composition in a silk cloth pouch immersed in molten Gandhaka (sulfur), enhancing the constituents’ potency and forming a highly therapeutic complex. Pottali Kalpana is characterized by high potency, minimal dosage requirements, rapid absorption into the bloodstream, quick therapeutic effects, ease of transport, and extended shelf life, making it suitable for emergency dosage forms. Pottali Kalpana is a consolidated form of mercurial preparation incorporating the Pota Bandha of Parada (mercury). This form of preparation results from Parada Murchana, a process where mercury is thoroughly ground with other herbo-mineral drugs to enhance its therapeutic efficacy. Pottali is a highly potent, concise medicament, exhibiting maximum potency in low doses. Its peculiarity lies in its unique shape, form, and preparatory methods. This article reviews different preparatory procedures, types mentioned in classical texts, dosage, mode of administration, and the significance of Pottali Kalpana. The review highlights the need for more research and documentation to analytically and clinically evaluate Pottali Kalpanas. Such studies are essential to validate their efficacy and safety, promoting wider acceptance and use in Ayurvedic practice.
