Method of preparation The method of preparing homeopathic medicines is called potentization; in this method, one part of the original drug substance (say, 0.1 mg of a plant extract) is mixed with 99 parts (9.9 mg) of a suitable carrier (say alcohol) and shaken vigorously by a special device that converts the preparation into the 1c potency. One part (0.1 mg) of the 1c preparation is then mixed with 99 parts (9.9 mg) of the carrier and the process of potentization is repeated to prepare the 2c potency. This process is continued until the required potency is reached Homeopathic medicines are available in certain standard potencies such as 30c, 100c, 200c, 1000c, 10K, and 50K.
