Triturations homeopathic

One part by wt of the 3rd potency of a drug prepared by trituration in lactose medium is mixed with 50 parts by wt of distilled water and the mixture is shaken or stirred. Fifty parts by wt of ethanol are added to the aqueous mixture so as to fill the vial upto two-thirds of its space. The vial is stoppered and shaken by 10 downward strokes. This is the 4th centesimal potency of the drug. Subsequent potencies are prepared by mixing one part by volume of the 4th potency with 99 parts by volume of 90% ethanol and subjecting the mixture to 10 succussions. In case of a decimal potency one part by wt of 6 x trituration of a drug is mixed with 50 parts by wt of distilled water in a vial. Fifty parts by wt of ethanol are added to the mixture which is succussed 10 times. This is 8 x potency of the drug. One part by wt of this potency is mixed with 9 parts by wt of 90% ethanol and the mixture is succussed 10 times to produce the 9 x potency of the drug. All subsequent potencies in the decimal scale are prepared in this way. The methods used by pharmacists are described in the Homeopathic Pharmacopoeia (Anonymous, 1920, 1962). Latest homeopathic pharmacopoeias are mentioned under 1.5.
