Trituration

The process of diluting a nonsoluble substance for homeopathic use by grinding it to a fine powder and mixing it with lactose powder.

trituration (tri·ch·rāˑ·shn),

n the initial steps during the creation of homeopathic remedies based on a source material that is solid or insoluble. This source material is ground together with lactose. Further potentization of the resulting liquid can be accomplished by dissolving it in water accompanied by vigorous shaking. See also trituration, C3 and dilution.
trituration, ball-mill,
n method in which an unspecified number of porcelain balls are homogenized in a porcelain pot with one part source material and nine parts lactose as the vehicle. See also trituration.
trituration, C3 (sē thrē tri·ch·rāˑ·shn),
n.pr 1., the three preliminary stages in the creation of homeopathic remedies by means of grinding source material (sometimes fresh plants) with lactose as the diluent. The degree of dilution is 3c.
2., trituration method used by Hahnemann on all kinds of source material such as petroleum, fresh plants or their expressed juices, mercury, or other liquids. See also trituration, fresh plant.
trituration, centesimal,
n grinding together 99 parts of sugar that is present in milk with one part of a homeopathic source material. Materials that are unable to be dissolved are triturated to 1/1000 (3c) before any additional suspension. See also trituration, C3; potency, centesimal; dilution; and suspension.
trituration, fresh-plant,
n the creation of homeopathic remedies by means of grinding fresh plants with lactose as the diluent.
