A beginner-friendly guide to the language on every homeopathic label — what 6X, 30C, 200C, 1M, and LM1 actually mean, how the three potency scales compare, and how remedies are dosed in acute and chronic care.
01 — The three scales
Every homeopathic potency belongs to one of three scales, named after the dilution ratio used at each step. The scale tells you how the remedy was made and roughly how deep it acts.
| Scale | Also called | Dilution ratio | How it's made | Typical potencies | When used |
|---|---|---|---|---|---|
| Centesimal (C) | CH, cH | 1 part substance to 99 parts solvent | One drop of the original tincture is added to 99 drops of alcohol and succussed (shaken vigorously). That becomes the 1C. One drop of 1C is added to 99 drops of alcohol and succussed to make 2C — and so on up the scale. | 6C, 30C, 200C, 1M (1000C), 10M, 50M, CM | The most widely used scale worldwide. Suitable for both acute and chronic prescribing. 30C is the common household potency; 200C and above are usually reserved for practitioners. |
| Decimal (X or D) | D, DH | 1 part substance to 9 parts solvent | One drop of the original tincture is added to 9 drops of alcohol and succussed to make 1X. One drop of 1X to 9 drops makes 2X, and so on. Each step dilutes one-tenth rather than one-hundredth. | 3X, 6X, 12X, 30X | Lower potencies that retain more of the original substance. Often used for tissue salts, first-aid, mild acute complaints, and in some countries for children and sensitive patients. |
| LM / Quinquagenimillesimal (Q) | Q, LM, Fifty-millesimal | 1 part substance to 50,000 parts solvent | A drop of liquid remedy (typically 3C) is added to 100 drops of alcohol, succussed, then one drop is added to 100 milk-sugar (saccharum lactis) pills. One pill is dissolved in a bottle of water and succussed before each dose. | LM1, LM2, LM3 … up to LM30 | Hahnemann's final potency scale, designed for gentle, repeatable dosing in chronic cases. Allows frequent repetition without aggravation. Almost always prescribed by practitioners. |

02 — Hahnemann's final scale
The LM, or fifty-millesimal, scale was Hahnemann's last refinement, set out in the sixth edition of the Organon. It was designed to solve a problem he kept meeting in chronic cases: how to dose gently and often without provoking aggravation.
Each LM step dilutes 1:50,000 — far more than a C step (1:100). Yet because the remedy is given in a water bottle and succussed before every dose, the same potency can be repeated gently. The result is a potency that is both very high in dilution and very mild in action.
One LM pill is dissolved in a bottle of clean water. Before each dose, the bottle is succussed (shaken firmly) a set number of times — often 8–10. A teaspoon is then sipped. The succussion slightly raises the potency with each dose, which is what allows repetition without the remedy "stalling".
03 — Practical guidance
The same remedy can be dosed very differently depending on whether the complaint is short-lived (acute) or long-standing (chronic). The table below sets out the practical differences.
| Aspect | Acute dosing | Chronic dosing |
|---|---|---|
| Goal | Stimulate the vital force to clear a short-lived, self-limiting illness. | Gently re-pattern a deep-seated susceptibility over weeks or months. |
| Typical potency | 30C is the household workhorse; 200C for intense episodes. | 30C, 200C, 1M, or LM potencies — chosen for the person, not the episode. |
| How often | Every 2–4 hours, reducing as symptoms improve; up to every 30 minutes in urgent first aid for a few doses. | Single dose, then wait. LM potencies may be given daily or every other day under guidance. |
| When to change potency | If improvement stalls after clear early progress, step up one potency (e.g. 30C → 200C). | Only after the current potency has clearly stopped acting — often weeks apart. |
| When to stop | As soon as symptoms are clearly improving, lengthen the interval, then stop. Do not dose through improvement. | Stop while improvement continues. Re-dose only when progress plateaus or old symptoms return. |
| Number of doses | Usually 3–6 doses; rarely more in a single day. | Often a single dose of a high potency, or a series of LM doses over time. |
04 — Reading the label
A homeopathic label packs a lot of information into a few characters. Once you know the pattern — a number, a letter, sometimes a second letter — you can read any potency at a glance.
| Notation | What it means | Example use |
|---|---|---|
| 6X (or 6D) | Six decimal dilution steps of 1:10 each. | A low, gentle potency — common in tissue salts and first-aid kits. |
| 30C | Thirty centesimal dilution steps of 1:100 each. | The standard household potency for acute self-limiting complaints. |
| 200C | Two hundred centesimal dilution steps. | A higher potency for intense acutes or deeper chronic work — usually practitioner-led. |
| 1M / 1000C | One thousand centesimal dilution steps. | A high potency for constitutional prescribing; given as a single dose. |
| 10M, 50M, CM | Ten thousand, fifty thousand, and one hundred thousand dilution steps. | Very high potencies used in deep chronic work by experienced prescribers. |
| LM1 / Q1 | The first step of the LM (fifty-millesimal) scale. | A gentle, repeatable potency for chronic dosing under guidance. |
05 — Safety & misconceptions
Potencies are widely misunderstood. The concerns below come up again and again — separating the genuine cautions from the myths helps you use remedies sensibly and know when to ask for help.
Higher potencies are more deeply acting, not more toxic in the material sense. By the time a remedy reaches 12C and above, there is essentially none of the original substance left. The concern with high potencies is over-stimulation (aggravation), not poisoning.
The carrier is usually lactose (milk sugar) pills, but the remedy is the pattern imparted through dilution and succussion. A blank pill taken without preparation has no homeopathic action.
Homeopathy follows the minimum-dose principle. Repeating a remedy while symptoms are improving can cause an aggravation. The signal, not the quantity, drives the response.
A brief, mild intensification of existing symptoms after a dose is often considered a sign the remedy is acting. A prolonged or severe aggravation, however, is a signal to stop, antidote if needed, and reconsider the prescription with a practitioner.
A “proving” is the appearance of new symptoms characteristic of the remedy itself — usually from too-frequent repetition. It is not toxicity. Stopping the remedy typically lets these symptoms fade; a practitioner can help antidote if they persist.
Homeopathy is a complementary system. Life-threatening conditions, severe injuries, and serious infections require conventional emergency care. A homeopath may support recovery alongside, never in place of, urgent treatment.
This page is a starting point for understanding the language of potencies. Real prescribing — choosing the remedy, the potency, the repetition, and the follow-up — is a skill built through study and supervised practice. Use this knowledge to read labels with confidence and to ask better questions of your homeopath.
