What are the Remedies Made From?
A "mother tincture" is made from plant and mineral sources, or a mixture of one or more diluted in pure alcohol and shaken (called succussion). These dilutions are in scales of either X (decimal) or C (centesimal). Dorwest remedies are the C scale.
What Strengths are They and What Do They Mean?
Homeopathic strengths (or potencies) are unusual as the MORE DILUTED the "mother tincture", the STRONGER the remedy is. 3C which has only been diluted a little is the least strong, a 30C which has been diluted a lot is the strongest. The higher the potency the quicker and deeper its reaction, although different potencies may have different effects. 30C is the highest potency that is normally available for self administration and is very effective for acute conditions.
