Centesimal and LM Potencies

One of the first questions of those new to the LM potency is how do the centesimal and LM potencies relate to each other in homoeopathic posology? After more than 14 years of comparing their actions I have come to the conclusion that there is no exact numerical equivalency. Comparisons cannot be made by mathematically analyzing the amount of the original substances present after dilution or by the numbers of succussions cumulatively given. There is a definite qualitative difference between the two potency systems as well as a quantitative one. Their similarities and differences become more apparent on the constitutions, sensitivities, and conditions for which they are most suitable. It is by comparing the powers of the two potency systems on similar constitutions, sensitivities, and diseases that we begin to build a correlation of their complementary but opposite remedial powers.

John Morgan, a pharmacist/homoeopath working at Helios Pharmacy Tunbrige Wells, England offers a comparison of the amount of original substance between the C and LM potency. The LM 0/1 has around the same amount of original material as a 6c. (5.5c); the LM 0/2 is equal to 8c; LM 0/3 is equal to 10.5c; and LM 0/4 is equal to 13c. It is at this point that  the potencies pass beyond Avogadro’s number . LM 0/30 has around the same amount of original material as 70c. Of course, these relationships are changed when 1 pill is dropped into 4 oz. of water and then 1 teaspoon of the medicinal solution is stirred into a dilution glass. Avogadro’s number is reached more quickly when the entire process in taken into account.

Those of us who have used the LM potency have seen that the remedies are much deeper acting than their centesimal counterparts in relationship to the amount of original substance left. Boenninghausen noted in his Lesser Writings that the 50 Millesimal remedies act as deeply as the higher potency centesimals. This is because the 1/50,000 ratio with 100 succussion  liberates a unique remedial potence that is essentially different from the 1/100 ratio with 10 or more succussions. The depth of penetration of the LM potency is more similar to the high potency centesimals than the low potencies. This is why one must learn how to use them correctly and know how to control their remedial powers.

Constitution and Sensitivity

It is not possible to give a linear mathematical comparison of the medicinal powers of the centesimal and LM potencies. They possess remedial powers that are quite different and have proved to be complementary opposites. I have obtained copies of the microfiches of Hahnemann's Paris casebooks from the Robert Bosch Institute in Stuttgart, Germany. During the years 1840 to 1843 Hahnemann commonly used the 7 tablespoon medicinal solution for both the C and LM potencies in his cases. He mostly used between 6c to 200c and a full range of LM potencies on his patients. He seemed to use his centesimals for the most acute diseases, crisis, or as acute intercurrents during the disruptions of chronic treatment. Hahnemann used his LM potencies mostly for chronic miasms, suppressions and degenerative states. This pattern is followed throughout his casebooks until he left for in his Heavenly Abode at 88 years old.

The pattern found in Hahnemann's cases led me to study the nature of the centesimal potencies and LM potencies more closely. In the 5th Organon Hahnemann states that the centesimal potencies are quick in their onset and tend to aggravation in the beginning of chronic treatment. In the 6th Organon Hahnemann states that the LM potencies are gradual and tend to aggravate at the end of treatment. I have witnessed this many times. This offers a clue to the differences of the remedial powers of the centesimal and LM potencies. Acute disease, crisis, and acute-like acerbations of chronic pathology all have the same qualities of quick onset and rapid crisis much like the aggravations of the centesimal potencies. The pattern of chronic disease is slow and gradual and it reaches its crisis toward the latter stages of development much like the aggravation of the LM potencies. The pace, progression and termination of the remedial powers and the acute and chronic states are similar. Is this the reason Hahnemann was testing the centesimal remedies in acute disease, acute-like acerbations of the chronic miasms or crisis? Did he use his LM potencies on the miasmic and constitutional states because they are more similar to the chronic disease process? Simillimum Simillimo!

In my 12 year trial in India I tested this hypothesis closely and found it was relatively true but not an absolute fact. I did studies with LMs in acute diseases and centesimals in chronic cases just to get a balanced perspective. It is quite true that the higher potency centesimals can do marvelous work in acute disorders and crisis. They also sometime perform miracles in functional diseases of a chronic nature. The most difficult area to use the high and highest potency centesimals is in chronic diseases with miasms, suppressions, iatrogenic disease and cases with serious organic pathology. In these situations it is very hard to manage the case with high potency centesimals. Hahnemann knew this from his experience of the 200c to 1M. That is why he began his new experiments. He decided that raising the potency further was not going to solve this problem. This is why he experimented with increasing the dilution rate instead.

This is indeed an area where careful control of the LM potency can perform wonderful cures and increase the quality of life and years of the elderly and those severely damaged by pathology. Many of the difficulties of the dry dose of the high potency centesimal in such cases are completely overcome by the new methods. Some of the quick acting qualities of the centesimal potencies are moderated by the medicinal solution, and rendered more controllable, but their essential nature remains. The centesimals have received an incredible number of 1 to 100 dilutions and succussions forced into a small dilution ratio compared to the LM potencies. This gives them their fiery nature and quickly penetrating remedial qualities.

The LM potency depends on its high dilution ratio to produce its deep acting remedial powers rather than the number of times diluted as in the Cs. They are also not as immaterial of a dose as the high potency centesimals. A 12c crosses Avogadro’s number while the LM 0/1, LM 0/2, and LM 0/3 still have material substance. This combination of the qualities of the high dilution rate and serial potencies provides the best qualities of a low and high potency. A 30c is much more immaterial then the LM 0/1 but its remedial actions have much less medicinal power. This is why the LM 0/1 acts more like a high potency yet it is still less immaterial. The LM potency is the balance point between the vital and the organic planes. This is why it is useful in advanced chronic diseases and miasms.

After many years of observation I have come to the conclusion that the centesimal potency suits some individuals while the LMs suit another. Sometimes one can only tell by hind sight after testing both potency systems on the same patient. Nevertheless, it does seem clear that the C potency suits traumas, acute diseases, acute miasms, acute-like acerbations of chronic diseases, chronic diseases that are still in a functional rather than pathological state, and chronic diseases that start with a serious crisis and rapidly progress toward pathology. The LM potency seems to suit the long term affects of traumas, acute diseases and acute miasms that have already produced organic pathology, crisis that slowly develops, disease with well developed organic pathology, and chronic diseases that develop insidiously over a period of years. The fact that the C and LM potency are complementary opposites greatly expands the therapeutic horizons of the homoeopathic pharmacy. For this reason, it is our belief that homoeopaths should take advantage of both potency systems.

The Sensitivity Scale

One area where the homoeopath can clearly compare the actions of the centesimal and LM potencies is on individuals of similar constitutional situations. Not all constitutions react in the same manner to the same potency. Hahnemann adjusted the potency of his doses in relationship to the constitutional susceptibilities of his patients. From these observations he was able to observe a quantitative difference in the sensitivity of a hyposensitive and a hypersensitive. Vide aphorism 281 of the Organon.

"If a cure is to follow, the first small doses must likewise be again gradually raised higher, but less and more slowly in patients where considerable irritability is evident than in those of less susceptibility, where the advance to higher dosage may be more rapid. There are patients whose impressionability compared to the unsusceptible ones is like the ratio of 1000 to 1 [DL]."

The sensitivity scale of 1 to 1000 demonstrates the vast variations that are found in the constitutions of individuals. A dose and potency which would not affect a hyposensitive could cause a terrible aggravation in a hypersensitive. The phenomenon of homoeopathic aggravation is related to three factors, i.e., an excessively large dose, too high of a potency and administration of a remedy when it is not needed. The methods of adjusting the dose were developed to give the homoeopath the ability to individualize the posology with the same care as when personalizing the selection of the remedy by the symptoms.

Judging Sensitivity

All individuals do not have the same sensitivity even if their vitality is relatively equal. If we studied the constitution and temperament of the individuals carefully we can observe certain signs and symptoms that give indications as to their relative sensitivity.

1. The hyper-sensitive patient (700-1000). The major signs of hypersensitivity include the following symptoms:

A. Highly nervous individuals, quick moving persons, rapid mood swings and quick alternations of symptoms, active senses, quick, strong reactions to environmental influences such as noise, lights, crowds, etc., the need to eat a careful diet, multiple allergies or chemical sensitivities, prone to side-effects from taking herbs and vitamins, etc.. They often have trouble sleeping. These constitutions are usually in a state of hyperfunction and hypertension and need to be calmed down.

B. Sensitivity is often increased in those with advanced tissue pathology, weakened vitality, oversensitive vital force, and a history of prolonged drug use or drug reactions. Care must always be taken in the elderly.

2. The hypo-sensitive patient (1-300). The major signs of hypo-sensitivity include the following symptoms:

A. These constitutions manifest the opposite states of a hypersensitive. Such person have slow movements, duller senses and intellect, the ability to eat almost any foods, herbs, vitamins, etc., reduced reaction to environmental stimuli (unmoved by noise, lights, smells, crowds, etc..). They rarely have allergies. These constitutions are in a state of hypofunction and need stimulation to get moving.

B. Sensitivity is sometime decreased in those who have taken too many drugs, especially tranquilizers and sedatives. They often lack energy and may be in a weakened condition and lack reactive capabilities. If they have weak vitality the homoeopath should be conservative with the dose and potency.

3. The moderately sensitive patient (400-700) represents your average constitutional sensitivity. The major signs are as follows:

A. Those of average sensitivity usually have good vitality and are moderate in their reactions to environmental stimuli. They are usually able to eat a broad diet and can take vitamins, minerals and herbs in reasonable doses. Few if any have allergies or chemical sensitivities. Their organs and tissues are neither hyperactive nor hypoactive. They demonstrate signs of moderation in all things. They are fairly stable individuals who are not prone to rapid changes in symptoms.

Once the homoeopath becomes a good judge of the constitution they can read the sensitivity to some degree. Of course, you never really know for sure until you give the first dose! This is why it is always best to give one test dose and assess the reaction of the vital force for a reasonable time.

The Choice of Potency and Dose

When to Use Low Potencies

Lower potencies, larger amount of water and small doses should be used in cases with *higher sensitivity* (700-1000), allergies, chemical sensitivities, weakened vitality, and highly developed tissue pathology. Care must be taken with elderly people and when the organs of elimination are overloaded by toxins as there is usually much hidden pathology. Low potencies can also be considered when the symptoms are of a common nature, the illness on the physical plane, and there are few characteristic signs.

1. With the *centesimal scale* the case should be started with 6c, 12c, 24c, or 30c depending on the individual. These cases do better on medicinal solutions made with 1 pill in 6 to 8 oz of liquid. The first test dose should be succussed only 1 to 3 times and the dose given in a small amount. It is best to stir 1/2 to 1 teaspoon of the medicinal solution into a dilution glass with 6 to 8 oz. of water. From this dosage glass give the client 1/2 to 1 teaspoon of the remedy. To modify the action of a remedy the homoeopath should use lower potencies, smaller amounts of the remedy, just a few succussions and more water as a buffering agent.

2. When using the LM potency in a true hypersensitive (700-1000) the dose must be carefully adjusted to act in a gentle manner. The case should be started with a 0/1 potency prepared in a medicinal solution of 6, 8 to 12 oz. of water. The remedy bottle should be succussed only 1 to 3 times and 1/2 to 1 teaspoon should be stirred into 6 oz. of water. From the dilution glass 1 teaspoon of medicinal solution should then be stirred into a second dilution glass of 6 oz. of water.. From this second dilution glass give the client a 1/2 or 1 teaspoon as a dose. Hahnemann mentions using 2, 3, 4, 5, 6 serial dilution glasses in the ultra hypersensitive. In this way we can treat over reactive individuals who would normally be very difficult to cure with Homoeopathy. Olfaction of the remedy is a good alternative to oral ingestion in hypersensitive patients.

A. In order to use a LM 0/1 on the same type of person who requires a lower potency like 30c the homoeopath must modify the dose accordingly. The LM 0/1 is a much deeper acting potency than a 30c. I have started many cases on 30c and moved them to LM 0/1 once they gain strength and stability and appear to need a higher potency to complete the case. If in doubt always choose the lowest potency and work up as needed.

When to Use Higher Potencies

High potencies are suitable for those with lower sensitivity (1-300), slow reacting nervous systems, clients who are non reactive to stimuli, and have functional disorders rather than advanced pathology. They are useful when the characteristic symptoms are mostly on the mental plane and there is good vitality. Another criteria is that the remedy picture is certain and there are clearly defined characteristics.

1. When using the centesimal scale one may begin these cases with relatively higher potencies such as 1M or 10M. Ultra high potencies (50M, CM, MM) are usually reserved for special circumstances or following a case through to completion after the previous potencies are no longer effective.

The solution should be made in an average of 3 1/2 to 4 oz. of water. The remedy bottle should be succussed between 8 and 12 times. If you using a very high potency it may be better to start with a lower amount of succussions such as 3 to 5 in the beginning and work up if needed. The client should be given 1 or increasing more teaspoons as needed. The centesimals may be taken directly from the remedy bottle, but in cases where there is concern about the possibility of aggravations a dosage glass should be prepared and the remedy diluted still further.

2. With the LM potencies the client may be started on LM 0/1, LM 0/2, and LM 0/3 depending on the variable factors of the case. Some that are truly at the low end of the scale may need LM 0/4, LM 0/5 and LM 0/6 as an opening potency. These must be considered as ultra high potencies. When using the LM 0/1 or LM 0/2 the remedy bottle may be succussed between 8 and 12 times to raise the potency. If one is beginning with LM 0/3, LM 0/4, LM 0/5, LM 0/6 it may be best to start with fewer succussions and work up as needed. When using the lower degrees of potency use more succussions, and when using the higher degrees use less succussions. The amount taken from the remedy bottle may be 1, or increasingly, 2 or 3 teaspoons of solution stirred into 4 oz in a dilution glass. The client should take 1, or increasingly, 2 or 3 teaspoons until a good reaction is attained. .

It is best to start with 1 or 2 teaspoons of the medicinal solution stirred into a glass and then slowly increase the amount until you get the reaction you want. The same is true with the amount of dosage out of the dilution glass. We usually begin with 1 teaspoon and then increase the amount to 2 or 3 until the proper reaction is elicited. With the lower sensitivities the homoeopath uses relatively larger amounts, higher potencies, larger numbers of succussions, and smaller amounts of water.

When to Use Moderate Potencies

Moderate potencies suit patients with an average sensitivity (400-700). These individuals demonstrate moderation in most areas. They are neither too weak nor too sensitive, and have functional diseases or the early stage of tissue pathology. They should have good vitality and their organs of elimination  function well. The remedy picture should be relatively clear and the characteristics somewhat marked. Moderate potencies work well on cases that affect the vital and mental level.

1. When using the centesimal potencies these cases may be opened with 200c to 1M depending on the circumstances. The average sensitive does best on a medicinal solution made in 4 to 6 oz which is given 4 to 8 succussions. From the remedy bottle the client usually begins with 1, or increasingly more, teaspoons until the healing reaction is established.

A. The method is basically the same for the centesimal and LM potencies although the dilution glass was not mentioned in the 1837 edition of The Chronic Diseases. Hahnemann was later witnessed using a dilution glass with the centesimal potencies also. I use the dilution glass in any case when I think it is better to be safe. This moderates the action of the remedy.

2. When using the LM potencies in the average sensitivity we usually begin the case with LM 0/1, LM 0/2 or more rarely LM 0/3 depending on the circumstances.. The size of the solutions is usual 4 to 5 oz. and the number of succussions used is 4 to 8. From the bottle 1 or 2 teaspoons are stirred into a dilution glass of 4 to 5 oz. from which the client takes 1, or increasingly more teaspoons as a dose.

This gives us a basic idea of the relationship between the sensitivity and constitutional states and the posology of the centesimal and LM potencies. Such ideas help guide us in the choice of potency, dose and repetition. One may find a mixture of signs in one individual as all the factors included are relative in nature. Average out the related signs and see where the predominance of factors point. One should always err on the conservative side in the choice of the potency and dose because it can always be increased if needed. Aggravations waste time, slow down the cure, and are uncomfortable for the patient.

A Review of the LM and Centesimal Potencies

Hypersensitive patients (700-1000+)

Hypersensitivity is composed of over reactivity of the constitution, idiosyncratic responses, the suppression of psora, suppression in general, quickly developing organic pathology, diseases which up-tune the vital force, and weakened vitality. The signs to look for include rapid mood swings, hysterical states, nervous temperaments, hyperactive senses, allergies, chemical and food sensitivities, quickly changing pathological tissue changes, diseases in the later stages, weakened vitality, and intolerance to changes in the environment, weather and climates. Study the physical constitution to see if you see diathetic signs of the chronic miasms or organic deformities.

Centesimals

Use 1 pill of the lower potencies like 6c, 12c, 24c, 30c in medicinal solution.

LMs

Use 1 pill of LM 0/1 in medicinal solution.

Only use 1 pill in a larger medicinal solution. In sensitive patients one can use from 5, 8, 10, 20, or more ounces of dilute to make the medicinal solution. A larger amount of water helps moderate the remedy right from the start. This medicinal solution should not be succussed more then 1, 2, 3 times at the onset of treatment. Only 1/2 to 1 teaspoon should be taken and stirred into 4 oz to 6 oz of water in a dilution glass. From this dilution glass only 1/2 to 1 teaspoon should be used for the first dose. The number of succussion and the number of teaspoons can be increased gradually if necessary to maintain a curative response. When treating the true ultra-hypersensitive with the LM 0/1 potency the dose must be moderated by diluting the remedy through a series of dilution glasses. Hahnemann mentions up to 6 dilution glasses. The LM 0/1's medicinal powers are much more developed than the 30 centesimal potency.

Moderate Sensitivity (400-700)

Constitutions of a moderate sensitivity (400-700) are the easiest to treat. The moderate sensitivity is of balanced temperament, relatively stable vitality, and their diseases are functional or at the beginning or early development of pathology. These individuals are fairly tolerant of different environments, foods and medicine.

Such constitutions can be started with the middle range potencies like 200c. In the LM system the 0/1, 0/2 or 0/3 are the normal opening potencies. The succussions should start at a moderate number like 4, 5, or 6. The average amount of the medicinal solution is 1 to 2 teaspoons stirred in a dilution glass. From this glass the individual is given 1 or 2 teaspoons  as a dose The dose can then be adjusted in the upward direction by more succussions and amount if necessary. Please refer to Hahnemann's Advanced Methods.

Hyposensitivity (1-300)

Constitutions low on the sensitivity scale (1-300). Hyposensitivity is composed of inherited constitutional sluggishness, slow temperament, low vitality reaction, venereal miasms, suppression, and diseases which under-tune the vital force and produce slowly progressive degenerative states. They are for the most part non reactive to environmental stimuli or weather changes, etc. The signs of hyposensitivity are flat mood, sluggish temperament, hypoactive states and slow developing symptoms and insidious degenerative processes. Investigate the physical constitution for the signs of the chronic miasms or congenital deformities which stimulate low reactivity. Normally, hyposensitive constitutions will have a history of lack of reaction to natural treatments and homoeopathic remedies. They often do not demonstrate the side-effects of allopathic medicines, and in many cases, do not believe very much in healing.

The hyposensitive constitutions usually need fairly strong stimulation to respond. They are suited to the higher potencies if there is not too much organic pathology. In general, those with functional disorders will tolerate remedies better than those with organic pathology. Many of these cases can be started on the 200c and 1M potency centesimals. Ultra high potencies like 10M, 50M, CM, and MM are normally reserved for later if needed. One, or in the most hyposensitive, two pills are used to make the medicinal solution. The upper range of the LM potency is also indicated in many of these cases. The opening potencies for true hyposensitives may be between LM 0/3, 0/4, 0/5, and 0/6. It is better to start lower and work up than cause unneeded aggravations.

The number of succussion should be at the higher end of the scale of 1 to 10. 7, 8, 9, 10, and increasing more, succussion may have to be used. Succussion can really 'shake up' the vital force and get things moving. Two or three teaspoons of the medicinal solutions should then be stirred into the dilution glass and 1, 2, 3 or increasing more teaspoons given as a dose until the desired response is attained. Many of these individuals do very well on the 'split-dose' of the medicinal solution or a series of dose. Refer to Hahnemann's Advanced Methods for the details.

The Fine Tuning of the Medicinal Solutions

Now that we have discussed the basics of sensitivity and dose we need to look at a few refinements and how to work up through the potency levels. There are two ways to adjust the amount of the dose of the aqueous solution. One way is to change the number of teaspoons of the medicinal solution and the other is to change the the number of teaspoons from the dosage glass. Increasing the number of teaspoons (1, 2, 3) of the medicinal solution stirred into a dosage glass makes the remedy act deeper progressively. At the same time, it dictates how fast one moves through the potencies. If one uses 1 teaspoon of a 4oz MS that makes 24 doses whereas if one uses 3 teaspoons from the medicinal solution that makes 8 doses. After finishing the LM 0/1 the standard practice is to move to LM 0/2 unless the case specifically dictates otherwise.

When one uses a larger amount of the medicinal solution, it not only increases the size of the dose, but also affects how fast one raises potencies. Therefore, the amount and the arc of the potency is increased at the same time. This means that in your lower average and hyposensitive constitutions the progression through the potencies, LM 0/1, LM 0/2, LM 0/3, LM 0/4, etc, is much faster than the progression a hypersensitive goes through. This is because a hypersensitive on the smaller amount, and larger medicinal solution, may stay on LM 0/1 for a very long time with only the cumulative succussions slowly raising the potency. The potency progression is almost self-regulating in relationship to the sensitivity scale.

The second method is to increase the number of teaspoons from the dilution glass. This is a more subtle increase of the amount and dose which does not affect the progressive rate of consumption of the medical solution or cause a more rapid ascent through the potencies. This, however, can make a great difference in the reaction in some sensitive patients. If you have a reaction but feel the need to increase the dose, this is often the best way to start. I tend to first adjust the action of a remedy up or down by increasing or decreasing the succussions. If I am not satisfied with this, I will change the size of the dose to larger or smaller amounts. First of all, I change the amount from the dilution glass, and secondly, from the medicinal solution itself. The same theorem is used with the centesimal potencies in medicinal solution.

Succussions Versus the Amount

There are two major ways to adjust the medicinal solution. They are increasing and decreasing the succussions and the size of the dose. How are these two methods similar and how are they different? This subtle question comes with experience in the method. These two methods form a functional polarity of complementary opposites. Succussions increase the potency causing the remedy to be more active while diluting the remedy decreases the amount of the dose moderating the effects of potency. In the best dose these twin factors balance with each other. May I offer an analogy? When we increase the succussions it seems to raise the frequency of the remedy to new harmonics. When we increase the amount it seems to increase the amplitude of the remedy. These have different effects on the vital force. The succussions seem to 'shake things up' while the amount seems to 'fill things out'. If I was going to use geometry as an analogy I would say that the succussions have a vertical affect while the amounts have a horizontal affect. The perfect balance of the two fills the entire space. When I need more medicinal power to stir things up I increase the succussions. When I wish to have more medicinal qualities I increase the dose. This phenomenon can be witnessed but it is hard to put into words.

Managing the Potency Factors

Normally, we work up through the potencies (LM 0/1, 0/2, 0/3, 0/4, 0/5 and 0/6, etc) as the solution is consumed. If one is not satisfied with the progress of the case, or the effect seems to slow down, the potency should be increased immediately. The same is true if a person seems to relapse, i.e. the potency should be raised. This is another reason you need to have LM 0/1, 0/2, 0/3, etc on hand. It is much the same as with the centesimal potencies. For example, if a 12c medicinal solution is not holding then the 30c might start the case moving forward again. Of course, the higher the potency, the deeper the effects, so more waiting and watching is in order with 200c, 1M, 10M, etc.. Nevertheless, with the medicinal solution in centesimal potencies there is no need to wait if the client is only slowly improving or wait for a complete relapse of the symptoms.

Once you have an LM 0/1 of a remedy it is fairly easy to make an LM 0/2, 0/3, 0/4, 0/5, 0/6 etc. This saves money but takes time and needs the right pharmaceutical supplies (alcohol, distilled water, droppers, and 1 dram vials). I have made many remedies in this fashion. One must learn when one must raise the LM potencies while you follow the case. As I said before most cases are started with LM 0/1, LM 0/2 and LM 0/3 but not all. This is like starting between 30 or 200 of the centesimal remedies. The action may be even deeper although the duration may not be as long in some cases. Starting an LM case with LM 0/4, LM 0/5 and LM 0/6 is like 200c, 1M, and 10M but not exactly the same. This is because the medicinal qualities of the LM are quite different from the centesimals. The qualitative difference must be learned through experience.

LM 0/1 has almost the same physical amount of the original substance as a 6c but it certainly does not act like a low potency! LM 0/1 is much deeper than a 30c and has the depth of a moderately high potency (at least 200c or above but it's not really the same thing!). The LM potency passes Avogadro’s number at around LM 0/4. This is speaking of the base tincture, not the amounts when they are diluted in the medicinal solution and the dilution glass. This causes the remedy to pass Avogadro’s number more quickly. So in a sense you have a remedy that is quite physical yet dynamic and has the best qualities of both a high and low potency. It has great depth and yet it is repeatable if and when necessary. The LM 0/1 is a much deeper acting remedy than a 30c. It is best not to think of the LM potencies as low potency remedies that can be repeated daily if you wish to avoid unnecessary aggravations and utilize them in the proper manner.

Hahnemann's "new methods" are equally applicable to the centesimal scale as the LM scale. The use of these complementary potency systems greatly expands the therapeutic horizons of Classical Homoeopathy. We call on homoeopaths to make experiments and take on trials with Hahnemann's definitive potency system. It will not be easy for those who are only used to the posology methods of the 4th Organon and the dry dose. Much new material must be digested and trials carried out so that one gains experience. Those homoeopaths who truly practice the methods of the 4th Organon are in a good position to take on the advanced methods. This is because they have mastered the wait and watch method and have real respect for the medicinal powers of homoeopathic remedies. With this strong foundation they have the background to truly practice the methods Hahnemann introduced in his last 10 years (1833-1843). Many who try to practice the LM potency without this background tend to approach these dynamic remedies in a mechanistic fashion. They do not have the experience in Homoeopathy to understand just what is needed and what must be learned. Many students of Homoeopathy are learning the correct way from the start which is indeed fortunate. As more experience is gained in Hahnemann advanced methods more qualified teachers will appear. Things are getting better.

I wish you all the best in your studies.
