to keep the ideal of Homoeopathy in mind, and think rationally ; in

tBrder to do that you will have to rid yourselves of a tremendous amount

of inheritance. We have inherited the way to think wrong end to.

'Tellowness of the skin from congestion of the liver, and catarrh

of the duodenum.” When persons have been over-medicated with

quinine until they take cold on every occasion, and a sudden attack of

congestion of the liver comes on, with the great soreness, and the skin

becomes yellow with all the sensitiveness of this remedy. Bell, will

cure such cases.

There are conditions that follow Bell, that relate to its chronic state.

Where Bell, has been suitable for the acute conditions, the congestions,

but there is that periodicity that I have mentioned, it has its natural

followers, and Calcarea is one of them. In boys that are big-headed,

plump, plethoric, precocious, that take cold easily, and come down with

headaches and congestion ; school children that get headaches which

Bell, at first helped ; very commonly if you look carefully into the

case it will turn out to be a Calc. case. It is so common for Calc, to

relate in this way to Bell. Now-a-days we frequently find the dry.

hacking cough in the hands of doctors who have given too much

Lachesis. Lachesis is commonly given to over-sensitive women, and

it produces many of those conditions; it sometimes cures great troubles, but it leaves behind for weeks a dry, hacking cough that keeps

her from sleeping. Sometimes it comes on after the first sleep, which

is commonly about 1 1 o’clodk ; a dry, hacking cough from lying

down. Bell, will cure this old' effect of Lack., the nervous state and

excitability and the cough. Bell, will be suitable as an antidote for

Lack., that is, for the acute symptoms. Calc, is an antidote for the

more chronic effects of Loch. After the abuse of Bell., Calc, comes

in as one of the natural antidotes.

Whenever we see in the nature of a remedy a well-defined state and

condition of the human system pointed out by certain distinctive groups

of symptoms we may know that there is such a diseased state in the

human family. They have not the power to create by themselves

any diseased state except there is first such a state in the economy

of the human race to be aroused. They simply call up in a single

individual something that the individual has, and that something belongs to the human race, and so whenever we see a diseased state in

the remedy we know that it exists in correspondence to something

in the human race. Things are so adjusted that everything is for use.

There may be conditions in the human race that we, as yet, know no

remedy for. We see certain groups of peculiar symptoms frcqhfcijtly

2i6

Lecture (part 2)
Kent

repeat themselves and we know they are representatives of a state of

the economy, but up to this day we may not have seen in the Materia

Mcdica their counterpart. In medicines we have the exact counterpart

for the diseases of the human race.

Now this remedy has a state and condition that is sometimes called

the gouty constitution, the uraemic or the lithaemic constitution, and

these cases are very difficult to manage, as the state is so persistent.

It is one of the manifestations of Psora. These patients sufEer more

or less from irregularity in the action of the kidneys ; sometimes the

urine is scanty and then they suffer from bodily complaints ; again the

urine is copious and then they are relieved of their complaints. They

are subject to rheumatic attacks and pains in the joints, showing the

gouty constitution, and then they have relief when the urine is copious

and heavily laden with deposits ; but on comes an attack when they

have more or less urine, but it is light in specific gravity, and then

they are full of pains ; in that way they fluctuate. Now, the young

prescriber will sometimes see the patient when he is passing large

quantities of uric acid forming the red pepper deposits and he thinks

he must stop that ; his main idea is to check that one particular thing.

But the patient is a great deal belter off while he has it. To check it

is like suppressing a skin eruption, or restraining any other manifestation of disease.

It will be noticed, as one of the foremost things in this remedy’s

manifestations, that it has strong smelling urine ; the urine is pungent,

and it sometimes becomes so strong that it smells like hippuric acid,

and so it is said urine smells strong like that of a horse. The odor in

this remedy approximates that of hippuric acid.

The complaints, then, of Benzoic acid are such as are changeable,

and we know why they arc changeable ; when the urine is copious and

plenty of uric acid is being passed, and the urine is full of deposits,

then the patient is at his best ; when the urine is scanty or of light

specific gravity he suffers from backache and pains in the joints,

he suffers from atmospheric changes, is sensitive to cold drafts and

to the air ; but let the urine start up again, which it does in a sort of

alternating way, light urine alternating with heavy urine, and the

patient is comfortable again. Then, there are complaints in which the

urine smells strong and pungent ; this often occurs in children. It is

astonishing that these little ones manifest the uric acid diathesis in

early life. Mothers often describe it as intensely urinous. It smells

like intensified urine; it is not the smell, so much, of decomposed

urine nor of foetid urine, but urine intensified. It has cured many

times wetting the bed involuntary urination in sleep, when riie bed

that has been wetted several times becomes uncleanable. You can

it almost as quick as you go into the room ; the children all tmt\l

Lecture (part 3)

like urine, strong urine ; the house smells like urine. If two or three

of these little fellows wet the bed at night, the urine is so strong it

tells the story at once.

This medicine needs reproving ; details have not been brought out,

yet its nature is known. We have a good many medicines having this

nature, but this is perhaps as intense as any. This remedy does not,

of course, fit all these patients, because it docs not fit their special

symptoms ; but it has the nature or general state which, of course,

precedes everything, and when it relates to all the particulars as well

it does make wonderful changes.

There arc a few mental symptoms. “Inclined to dwell on unpleasant things ; if he saw anyone deformed, it made him shudder,*'

Alternation of profound sleep with prolonged periods of wakefulness.

In the period of wakefulness, he dwells, during the night, upon all

the unpleasant subjects that he can think of. This state alternated

with nights of stupid sleep for weeks, and this fluctuates in accordance

with the fluctuation of the state of urine. “Sadness." “Anxiety while

sweating.* “Child cross.’

There are many headaches ; they arc urtxmic in character and come

  • in many regions with many details.
  • “Fearful pain in occiput or cerebellum.
  • ” “Rheumatic pains in head.
  • ” That is well described, because

these headaches of unxmic character take on a similarity to rheumatic

pains, “Pain and heat in regidn of organs of reverence and firmness.”

“Tearing pain in vertex.” Xte headaches arc very numerous ; thp

remedy is full of dull, achingf occipital headaches, coming on in the

night from change of weather. Pains located in the base of the brain

after pains have existed for some time in the joints, and they are

passing but little urine. Every time he takes a little cold the urine

becomes scanty and he is full of dull aches and pains in the head and

especially in the occiput.

Perversion of smell. “Sense of smell diminished.” “Pain in nasal

bones.”

Another form of transformation scene takes place in this remedy,

when all the gouty symptoms of the body cease and inflammation of

the tongue comes on. The pains in the joints cease suddenly from taking cold, from stormy weather and on comes a sudden swelling of the

tongue. Mercury also has this state. “Extensive ulcerations of

tongue, with deeply chapped or fungoid surfaces.” Then, again,

peculiar kinds of sore throat take place from this same /ause. Sudden

stoppage or slacking up of the quantity of urine ; it becomes scanty,

high colored, and pungent, smelling like that of a hoarse {Nitric acid)

along with acute inflammation and swelling of the tonsils and throat ;

inflammation of the tonsils with scanty, strong, pungent urine smelling like that of a horse. Another feature that seems almost like

2t8

Lecture (part 4)
Kent

metastasis. Take an individual who is going around with more or

less rheumatic aches in the joints; he takes cold and all this ceases,

but the next day he comes down with inflammation of the tongue or

sore throat, or inflammation of the stomach ; so that he vomits everything he cats. The gout goes to different parts and in this instance

it goes to the stomach ; and then Benzoic acid, Antimonium crud. or

Sanguinaria is likely to be useful. When it goes to the throat or is

followed by swelling of the tongue Mercury and Benzoic acid should

be thought of. Whenever this gouty condition goes to the stomach,

of course it must conform to those symptoms that are in the nature

of this remedy. In this remedy we have ‘loathing, sickness at stomach,' “nausea with gagging,’ “vomiting of a salty substance ; bitter.”

When we think of Benzoic acid for the stomacli symptoms, it is important that we have in mind its whole nature, how it brings about its

complaints and what characterizes a Benzoic acid patient. We would

not be able to distinguish from the stomach symptoms alone ; wc must

carry with them the character of the remedy.

It has much disturbance of the liver, and many liver symptoms.

As to the bowels, the stool, the rectum, anus and urinary organs, it is

very rich in symptoms. Its striking ones I will call your attention to,

but remember its migrating, metastatic nature, its complaints going

from one part to another, which will accompany these symptoms.

“Stools, copious, watery.” This is true in ssummer diarrhoea, that has

come on suddenly, “excessively offensive,** The white stool, like

soap-suds, is so strong a symptom that the remedy does not fail to cure

even when the gouty constitution is not present. “Excessively offensive,

scenting the whole house.” “Putrid, bloody.” “Watery, light-colored,

very offensive stools (in children).** So wc get the idea that the stools

are white and that the first passages are like soap-suds, but later the

soap appearance subsides and leaves a white stool. It is well, often,

when a stool is passed that is of a light liquid/ to bear in mind a few

lemedies that produce this state and ascertain whether it is like soapsuds or filled with bubbles of air. “Diarrhcea of children.** The urinous

odor of the body, and especially that peculiarly pungent, intense smell

of the urine. “Slightly elevated, wart-like, round surfaces around anus.”

Lecture (part 5)
Kent

The urinary symptoms are too numerous to read. “Foetid urine.”

“Urine of a very repulsive odor.** “Effervescing with hydrochloric

acid.” The odor is sometimes like hartshorn ; it is pungent ; these are

only efforts to describe the strong smell. “Urine dark brown,” It is

true that normal urine after standing a while will get a foetid odor,

  • but, in this remedy, that just passed is properly described as being intensely urinous.
  • “Urine contains mucus and pus.
  • ” “Morbid condition of urine.
  • *’ “Renders urine acid. ” It says in the text “hippuric

acid,” but this i^ a rare condition. “Brown urine smells sour.” “Too

m

frequent desire to evacuate bladder/' “Nephritic colic." ‘‘Urine dsurk/

urinous odor highly intensified.’* Gouty troubles of the liver ; rheumatism ; nephritic colic ; it has cured such states after gonorrhoea, but

it is not much of a gonorrhoeal remedy. When the rheumatic states and

these symptoms are present there are more or less pains in the kidney.

“Sore pain in the back ; burning in the kidney." “Prolapsus uteri

with foetid urine." “Retention of urine in infants."

“Asthma with inflammatory rheumatic complaints." “Cough followed by expectoration of green mucus."

The organ that is most commonly affected in these rheumatic complaints is the heart. No organ is so likely to be affected when rheumatism leaves the outermost parts as the heart. Pains in the heart.

So in this diathesis, with the strong smelling urine and the gout, we

may expect affections of the heart. “Pains change place incessantly."

“Palpitation of the heart." The rheumatism, of course, is affecting

the heart. “Awakens after midnight with violent pulsations of the

heart." Think a moment and you will sec in what kind of a case you

will need Benzoic acid The constitution of the remedy comes to

mind at once with the heart symptoms, the dyspnoea, pain in the heart

with rheumatic symptoms ; “cannot go io sleep." Think of the alternation of sleeplessness with sleep ; think of the strong urine, of the

fluctuating complaints, of the erratic constitution. “Palpitation worse

at night." “Rheumatic pains in extremities relieving heart." There

we get relief ; complaints gqilig back to the extremities with relief to

the heart. The heart will |elieve when the urine becomes copious

or when the rheumatism goes back to the extremities, into the fingers

and knees, especially the knees in Benzoic acid. Rheumatism alternating between the extremities and heart. This medicine has cured affections of the heart when the rheumatism has a long time ago disappeared from the extremities and has ever since been affecting the

heart ; after Benzoic acid has been administered a very good sign of

its action is that the extremities become painful and the urine becomes

copious ; free urine and solids increased ; the urine becomes heavy,

whereas it was light. “Hard, frequent pulse.”

Lecture (part 6)
Kent

The extremities are full of rheumatic affections. “Lassitude in lower

limbs." “Swelling of knee." All gouty affections belong to this

  • remedy.
  • “Gouty concretions.
  • " “Nodes on joints.
  • " Benzoic acid is often

an excellent palliating remedy in old gouty constitutions ; they want to

be relieved of the pains in their fingers and in the nodes and joints.

The fingers crack and are clumsy and painful. But often the pain

has been relieved and gone to other parts. This is one among the

remedies that will drive the complaints away from the internal organs

and generally increase the pain in the extremities, which they will scold

about. “Trembling with palpitation of heart." “Extreme weakness ;

fiEBBElUS

sweat and comatose condition.” Note that comatose condition with

sweat ; the Benzoic acid patient sweats without relief. Copious, exhaustive sweat and profound sleep, but there is no relief. “Awaken

with difficulty of breathing.” Pulsation all over.

“All sorts of catarrhal states ; gouty diathesis, gout with arthritic

nodosites syphilitic rheumatism, etc,” These patients are getting

low down in the scale of life, the tissues become feeble. Ulcers form

upon the skin and mucous membranes.
