Ayurvedic Herbal Powders – Churna
Ayurvedic Herbal Powder or Churna is a powdered form of medications used in the treatment of disorders in the Ayurvedic system of medicine. It is the most basic and simplest form of Ayurvedic medicine containing a fine powder of herbs. Churna may contain a single herb or a mixture of several herbs.
Method of Preparation of Churna
All the ingredients required for the Churna should be cleaned thoroughly and dried well in the shade or in the sun separately to ensure the complete absence of moisture in the same.
Each ingredient is powdered finely and then, sieved to remove any coarse particles. The ingredients are weighed separately and then, mixed together. It should be noted that some herbs contain a fibrous matter. Hence, the weight of such herbs may vary before and after drying. Hence, it is important to powder and weigh them separately so that the correct quantity of each herb can be present in the final product.
The powders of all herbs are mixed in the required quantities. Salt, sugar, and camphor may be added to the mixture if mentioned in the formula. Churna, thus obtained, should be kept in an air-tight container.
When the formula contains HINGU (Asafetida), it should be roasted before grinding them into a powder. If a formula contains salt, then it should be added in the end.
Some herbs such as Guduchi and Shatavari are used fresh. These herbs should be made into a paste and then, dried before adding them to the formula.
The final product should be fine of at least 80 mesh sieves. Also, the powder should not adhere to the bottom of the container or to each other to form clumps. They should not bind together or be moist.
