Part 1: Development of the LM Potency

Introduction

A homoeopath should have a deep knowledge of the models of the 4th and 5th Organon to understand the Homoeopathy of the 1840s, which is found in the 6th edition. Homoeopathy as commonly practiced today is based on the single dry dose wait and watch method of the 1st Chronic Diseases (1828) and the 4th Organon (1829).

In this method a single pellet dose of the centesimal potency is used as long as the patient is improving even in the slightest manner. Many of the great 19th century homoeopaths like James Kent were masters of this method.

The dry dose may only be repeated when there is a definite relapse of the old symptoms calling for repetition. Hahnemann was not completely comfortable with this method in cases that only slowly improved over a longer period of time.

For this reason, in the 5th Organon (1833) Hahnemann introduced olfaction and the oral medicinal solution as a new delivery system for homoeopathic remedies. The change from a dry static pellet dose to a dynamic medicinal solution succussed prior to administration had an immediate impact on his posology and case management strategies.

In the 5th Organon he suggested any "striking progressive improvement" precludes the repetition of the remedy because the cure is already taking place at the fastest possible rate.

At the same time, he taught that the single dose was not sufficient for those cases that slowly improve over a period of weeks to months. For these cases the Founder recommends administering the remedy in medicinal solution or olfaction at "suitable intervals to speed the cure".

Hahnemann called this his new "middle path" as it stands between the single dose wait and watch and the mechanical repetition of remedies. This is a truly artistic method that demands individualization of the case management procedure.

Over the next 10 years Hahnemann worked exclusively with the medicinal solution for oral administration and olfaction. Around the year 1840 the Founder began to introduce his new LM potency into clinical practice to complement his C potencies.

The discovery of the new 1/50, 000 dilution ratio introduced a new potency system with unique medicinal qualities. From the year 1840 to 1843 the Great Experimenter used both the C and LM potencies side by side in medicinal solution. This new double pharmacy greatly expands the therapeutic horizons of Homoeopathy.

The Paris Casebooks

I wish to review the posology systems of the 5th and 6th Organon in relationship to the centesimals and LM potencies. It is very important to study the remedial powers of Hahnemann's twin potency systems and recognize their similarities and differences.

The most important aspect of the revised methods of the 1840's is the medicinal solution and the methods of adjusting the dose. Many people think that Hahnemann used the dry dose for his centesimal potencies and the medicinal solution exclusively for the LM potency. This is incorrect. The Founder used the C and LM potency side by side in the clinic in medicinal solution from 1840-1843.

An investigation of Hahnemann's cases from 1840-1843 shows that he used a remedy bottle with the addition of a dilution glass for all his homoeopathic remedies (C and LM). In his last 10 years he refined the Homoeopathy of the 4th Organon (1829) and expanded his posology and case management strategies. So the first point is that Hahnemann introduced his revised liquid method for the centesimals in 1833 and the LM potency in 1843.

The Mother of All Potencies

The 3c is the mother of all homoeopathic potencies.  When Hahnemann first proved Arsenicum in 3c he wrote an article in 1806 titled "What are medicines and What are Poisons?". The 3rd Centesimal was the first true homoeopathic dynamization and the root of the centesimal scale. At the 1 to 1,000,000 ratio 3c marks the level that homoeopathic remedies become non-toxic. For 34 more years he would run trials with raising the potency of the centesimal scale until he had experimented with the 3c to the 1M.

After years of experiments he settled on the 6c, 12c, 24c, 30c as the most suitable lower potencies. With his low potencies Hahnemann started with the 30c potency and then used the 24c., 18c., etc., in their descending order.

He continued to lower the degree of his low potencies 30c - 6c in his last years 1840-1843. At the same time, the Paris casebooks record him raising his high potency C's through potencies like 197c, 198c, 199c, 200c.

Melanie Hahnemann wrote a letter that stated that Hahnemann used a 1M potency on occasions during his experiments. It seems he kept his high potencies separately from his low potencies, in small tubes with poppy seed size pellets. The Founder always gave his high potency Cs in medicinal solution just like the LM potency.

At 85 years old the Founder came to another turning point in his long career. With his young wife Melanie at this side, Samuel Hahnemann began to ponder his legacy.

Homoeopathy had come a long way since its birth in late 1700's, but the old homoeopath was not satisfied with his system. The medicinal solution had greatly improved the treatment of the virulent acute, and degenerative chronic diseases, but the weak, the elderly, and those suffering from the chronic diseases and miasms still presented a particular dilemma.

When Hahnemann used his low potencies (6c, 12c, 24c, 30c) they would not cure but if he used the high potencies (200c-1M) they produced unproductive aggravations.

What could he do with this unfortunately large percentage of cases that still resisted homoeopathic treatment? This was a lacuna in his therapeutic system that he wished to fill before he died.

Development of the LM Potency

After 36 years of raising the potency of the centesimal remedies, Hahnemann decided to raise the ratio of dilution instead. Leaving the 1/100 dilution ratio of the centesimals behind, Hahnemann started searching for a potency that would fill this hole in homoeopathic therapeutics.

After countless experiments the Founder settled on the 1/50,000 dilution ratio associated with the 50 Millesimal potency. I have reviewed 100s of Hahnemann's cases from the LM period (1840-1843) over the last 2 years.

One of the first things one notices is that Hahnemann used both he centesimal and LM potency in medicinal solution with the addition of a dilution glass during these 3 years.

The LM potency is first made from the 3c trituration (1:100x100x100). Next 1 grain of this trituration is placed into 500 drops to make the LM/0 solution (1 to 501 ratio). Then 1 drop is taken from the LM/0 solution and added to 100 drops of dilute and succussed 100 times.

This makes the LM 0/1 potency, the first degree of the LM pharmacy (100x100x100x500x100x500 = LM 0/1). The C's of the 5th Organon (1833) were made with 10 succussions by hand although many modern potencies are made with 10 to 40 or more succussions by machine.

When speaking of the amount of original medicinal substances in the LM 0/1 it is similar to the amount found in the 6c potency although its remedial powers are greatly expanded due to the larger dilution medium.

A mere comparison of the amount of original substances found in the C and LM potency does not show the differences in their inner medicinal qualities. The LM pharmaceutical solution is then used to moisten 500 tiny poppy seed size pellets.

One pellet of the LM 0/1 is further diluted in a minimum of 3 & 1/2 oz to make the medicinal solution. After succussions 1, 2 or 3 teaspoons are taken from the medicinal solution and further diluted in a dilution glass of water.

From this dilution glass 1, 2, 3 teaspoons are given to the patient as a dose. The final liquid dose has been diluted through two more stages than the dry dose. The final amount of original substance given to the patient is more diluted than the dry pill  since it has been dissolved in the medicinal solution and stirred into a dilution glass.

This final amount of original substance in the teaspoon of solution given to the patient has yet to be calculated in the equation.
