What does the "X" after a homeopathic ingredient mean?
The "X" refers to the level of concentration or dilution of the basic medicinal substance which was used to make the finished product. A basic medicinal substance may be a "Mother Tincture" of a plant or animal or the mineral itself.
1X means the dilution contains 1 part basic medicinal substance combined with 9 parts of diluent
2X means the dilution contains 1 part of a 1X tincture with 9 parts diluent. So a 2X dilution is 1 part basic medicinal substance and 99 parts diluent or a 1% extract, as shown below:
Mother Tincture Concentration Levels:
1X: 1 part in 10 or 10%
2X: 1 part in 100 or 1%
3X: 1 part in 1000 or 0.1%
4X: 1 part in 10,000 or 0.01%
... and so on.
"MT" means "Mother Tincture" (described above). Most Mother Tinctures are a 10% extract of the pure plant or animal and generally are designated as a 1X potency.
"MT(N)" means that the Mother Tincture for this ingredient in the product contained a 33% extract of the pure plant.
"MT(M)" means that the Mother Tincture for this ingredient in the product contained a 50% extract of the pure plant.
