Homeopathic Dilutions and Mother Tinctures

What does the "X" after a homeopathic ingredient mean?

(e.g., Arnica 4X)

Most homeopathic ingredients are dilutions of the basic substance, which may be a plant, animal or a mineral substance. The level of dilution is identified using different symbols, for example, an “X” for Decimal dilutions (1 part material/9 parts diluent) or “C” for Centesimal dilutions (1 part material/100 parts diluent).

The homeopathic remedies from Hevert Pharmaceuticals and their homeopathic ingredients are produced according to the rules of the German Homeopathic Pharmacopoeia (GHP):

  • 1X means the initial dilution of the basic substance from plant, animal or mineral origin.
  • 2X means the dilution contains 1 part of a 1X dilution and 9 parts of diluent.
  • 3X means the dilution contains 1 part of a 2X dilution and 9 parts of diluent, and so forth.

What does "TM" or “MT” after a homeopathic ingredient mean?

(e.g., Carduus marianus TM)

"TM" or “MT” means "Mother Tincture", which is a special extract of plant or animal material, produced according to the rules of a homeopathic pharmacopoeia (e.g., HPUS or GHP). Most Mother Tinctures are extracts that contain about 10% of the basic substance.
