An important drug that is made from Praval is Praval Pishti which is indicated in Kasa Roga, pitta disorders and shows great significance.


How Praval Ratna medicines are made?

Rasa Shastra is a particular branch of Ayurveda in which Ratna (gems) and Upratna (minor gems) play a unique role in both ornamental and medicinal applications. Various techniques like Shodhana (purification), Maran (incineration), and Pishtikarana are utilized to convert the natural drug for medical benefit. Ratnas are high-quality gemstones that can bind the mercury.

Ratnas (gems) are nine in number and each gemstone is associated with a planet and is said to exhibit biological effects. Praval stone is related to mangal Graha hence wearing this stone pacifies the mangal Graha.

In Ayurveda, these Ratnas are utilized as a drug for therapeutic purposes. Various forms of these drugs are prepared and utilized only after their non-toxic certification.
