What Exactly is Khatika?
Khatika ($Khaṭikā$) is a Sanskrit term that refers to chalk. In the context of Rasashastra, the branch of Ayurveda that deals with mineral and metal-based medicines, Khatika is a mineral used in therapeutic preparations. It is a form of limestone, a soft, porous, sedimentary carbonate rock. The mineral is primarily composed of calcium carbonate ($CaCO_3$), and its powdered form is what constitutes Khatika Churna. The name Churna simply means 'powder,' so Khatika Churna literally translates to 'Chalk Powder.'
The Importance of Shodhana (Purification)
In Ayurveda, no mineral or metal is used for medicinal purposes without being subjected to a rigorous purification process known as Shodhana. This process is crucial for cleansing the mineral of impurities and enhancing its therapeutic properties. For Khatika, the Shodhana process involves washing the chalk powder in clear water to remove any soluble impurities. After washing, the fine paste is dried and then used in formulations. This step is a testament to the meticulous approach of Ayurvedic pharmacology, ensuring the safety and efficacy of mineral-based preparations.
Ayurvedic Properties and Benefits of Khatika Churna
Ayurvedic texts describe the properties of Khatika Churna based on its Rasa (taste), Guna (qualities), and Virya (potency). The medicinal applications are extensive, and it is known to be beneficial for a number of ailments.
- Relieves Digestive Issues: Known to soothe symptoms like indigestion, dysentery, and malabsorption syndrome by mitigating the imbalance of the Pitta dosha.
