How to measure 250mgms with small spoon.

      Sir, If your physician has prescribed then take it with water only.

      Note: As we all are genetically different with different constitutions and patterns, we respond to treatments in many different ways. Hence Standard Ayurvedic Treatments are always individually formulated.


    Dear sir,

    The article is excellent.

    Please clarify:
    How water stored in Shank ( Conch) overnight and taken in the morning helps as per Ayurveda. Please elaborate, if it helps.


    • Hi, water stored in any vessel will get some amount of qualities from the nature of the vessel. For example, curd stored in brass or copper vessel will react to liberate hydrogen gas.
