Homeopathic potencies, explained honestly: 6C, 30C, 200C
What potency numbers actually mean, how the dilution math works, why the convention exists, and how to think about potency without mystifying it.

Potency labels confuse almost everyone who meets them, partly because they run backwards from ordinary intuition: in homeopathy's convention, more dilute is labeled higher. This guide explains the system plainly — including the part most sellers skip.
What the numbers and letters mean
A potency label like 30C describes a preparation process, not a quantity of medicine.
- The letter is the dilution ratio. C means 1:100 — one part of the previous solution into ninety-nine parts of water or alcohol. X (sometimes D) means 1:10. LM (or Q) means 1:50,000.
- The number is how many times that step was repeated. 6C means the 1:100 dilution was performed six times in sequence. 30C means thirty times. Between each dilution the preparation is succussed — shaken firmly against a surface — which tradition treats as essential to the process.
So 6C, 30C, and 200C are the same starting substance carried through the same procedure a different number of times.
The honest math
Here is the part a trustworthy explanation cannot skip. Each 1:100 step multiplies the dilution: 6C is a 10⁻¹² dilution, 12C is 10⁻²⁴, 30C is 10⁻⁶⁰. Chemistry's Avogadro limit sits near 10⁻²³ — beyond roughly 12C, it is unlikely that even one molecule of the original substance remains in the vial.
Homeopathy has always known this; the tradition's claim is that the preparation process itself matters, not molecular dose. Mainstream science does not accept that claim, and we discuss what the research record says in homeopathy and the evidence. We would rather you know both things than have the label mystified at you.
One practical consequence worth stating clearly: it is also why properly prepared high-potency remedies are not a toxicity concern in the way the raw source substances (some of which are genuinely poisonous plants and minerals) would be.
How potencies are traditionally used
Within homeopathic practice, convention runs roughly:
- Low potencies (6X–12C) — traditionally discussed for repeated use over physical, local complaints.
- Medium potencies (30C) — the common household and acute-kit convention; most over-the-counter remedies are 30C.
- High potencies (200C and up) — traditionally reserved for practitioner-managed situations, chosen alongside the whole case rather than off a shelf.
These are conventions of the tradition, not medical instructions. Nothing here tells you what to take; that depends on a whole case picture, which is a conversation, not a label.
What actually matters more than potency
Newcomers agonize over potency selection. Practitioners generally agree the far more important question is whether the remedy pattern fits the case at all — the subject our acute pages exist to teach. A well-matched pattern in a common potency is a more coherent choice than an exotic potency of a remedy chosen by the complaint's name alone.
Ordering a specific potency
If you already know the remedy and potency you want, our custom single remedy service prepares to order — you tell us the remedy, potency, and format, and we confirm availability and exact price by email before anything is made. If you want help thinking about which pattern fits a situation, that is the acute consultation instead; the order form deliberately does not give advice.
