Homeopathic Materia Medica

Lectures on Homoeopathic Materia Medica, James Tyler Kent

Modalities: The complaints of this remedy come on from cold damp weather, from being exposed to cold damp air when perspiring.

The patient is sensitive to cold air and all his complaints are made worse from cold and all are better from warmth. In a general way, the aching pains, the bruised feelings over the body, restlessness throughout the limbs, and amelioration from motion are features that prevail throughout all conditions of Rhus.

While he is better from motion and better from walking, if he continues to walk he becomes exhausted. Any continued exertion of the body or mind exhausts the Rhus patient. He suffers from rheumatic conditions with pains in the bones, lameness in the muscles, lameness in the tendons, ligaments, and joints from suppression of sweat, from becoming chilled.

These occur with or without fever. Rhus is suitable in old chronic rheumatic conditions. He is stiff, lame, and bruised on first beginning to move. This passes off on becoming warm up, but soon be becomes weak and must rest.

Then comes the restlessness and aching and uneasiness which drive him to move and which again make him better, but soon he becomes weak and these continue, so that he is never perfectly at ease and never finds rest. Inflammation of the glands and of the mucous membranes; inflammation of the muscles. Cellulitis of the pelvis, of the neck, about the glands with much swelling. Inflammation of the skin that becomes erysipelatous; purple; pitting upon pressure with large blisters that fill with serum, sometimes bloody. It has abscesses and carbuncles and vesicular eruptions.

Its complaints are more or less periodical. It has cured many cases of intermittent fever, is often suitable in remittent fever, and is a most useful remedy in continued fevers and in a low form of typhoid fever.

Pains: The pains that run through Rhus are aching, tearing, and bruised pains often attended with numbness and paralytic weakness of the limbs.

It has paralysis of the limbs with loss of sensation. In infantile paralysis Rhus is a very common remedy. The nurse-girls at the present time often bring on in the child this paralytic condition and spinal paralysis. The nurses take the infants to the park, take them out of their carriage and put them down upon the cold damp ground and in a few days the child comes down with infantile paralysis. Rhus will cure these cases because the symptoms take the Rhus type. Hemiplegia, especially of the right side. Twitching of the limbs and muscles. It has cured chorea brought on from taking a cold bath.

Mind: Most of the mental symptoms of Rhus are such as prevail during low forms of fever, especially in typhoid.

There is then incoherent talking; answers questions hastily. There is anxiety, apprehensions, and fear. Intense fear at night. The complaints of Rhus often come on in the night. The mental symptoms are worse at night. The delirium is worse at night.

The fears and anxiety are worse at night. The chronic mental symptoms of Rhus are despondency, mental prostration, inability to sustain a mental effort, disgust for life and thoughts of suicide. He wants to drown himself yet he has fear of death. He desires to die yet he has not the courage to commit suicide.

There are violent pains in the back, especially in the lumbar region, as if the back were broken. It is a remedy for lumbago brought on from getting wet, from overlifting, from taking cold, and from suppressing the sweat. He is ameliorated from motion and from moving about; worse on beginning to move.

This remedy has many spinal symptoms with paralytic weakness either of the lower limbs or of one part of the body, Stiffness and lameness in the sacrum aggravated on resting after exercise. It might now be predicted that symptoms are to be found in the limbs from what has been said in general.

There are stitching pains, pressing pains, all sorts of rheumatic lameness, and these pains are ameliorated from motion and are worse from keeping still. They are brought on from cold air and from suppressing the sweat, and as these pains grow worse they became tearing down the limbs, drawing pains.

In sprains such as occur in the ankles and in fact any of the joints, after Arnica has removed the first and most painful symptoms, Rhus becomes useful for weakness of tendons and muscular fibers such as always follows sprains.

It is a routine remedy for this weakness in joints following sprains. The pains rush in streaks down the limbs; restlessness in the lower limbs at night, but amelioration from motion; must keep the limbs in constant motion; paralysis of the lower limbs, great weariness and heaviness of the lower extremities; weakness of the lower limbs on going up stairs; swelling of the joints of the lower limbs; stiffness of the knees and feet.

Large blisters form upon the skin either with or without erysipelas. The incessant itching is sometimes relieved by "scalding" the parts, as it is called by some who are poisoned with Rhus, by "scalding" with water as hot as it is possible to bathe the parts in. Rhus has cured shingles and the tendency to herpetic eruptions. It has made a grand record with humid eczema such as have raw surfaces; excoriated; oozing much. It is very commonly the remedy for hives that come on from getting wet or hives that come on during rheumatism or during chills and fever; hives that are worse in the cold air.

Ailments: from spraining or straining a single part, muscle or tendon (Cal., Nux); overlifting, particularly from stretching high up to reach things; lying on damp ground; too much summer bathing in lake or river. Affects the fibrous tissue, especially (Rhod. - serous, Bry.); the right side more than the left. Pains: as if sprained; as if a muscle or tendon was torn from its attachment; as if bones were scrapped with a knife; worse after midnight and in wet, rainy weather; affected parts sore to touch. Lameness, stiffness and pain on first moving after rest, or on getting up in the morning, > by walking or continued motion.

Restless, cannot stay long in one position. Back: pain between the shoulders on swallowing; pain and stiffness in small of back < sitting or lying, > by motion or lying on something hard. Great sensitiveness to open air; putting the hand from under the bed-cover brings on cough (Bar., Hep.). Muscular rheumatism, sciatica, left side (Col.); aching in left arm, with heart disease. Great apprehension at night; fears he will die of being poisoned; cannot remain in bed. Vertigo, when standing or walking; worse when lying down (better when lying down, Apis); < rising from lying, or stooping (Bry.). Headache: brain feels loose when stepping or shaking the head; sensation of swashing in brain; stupefying; as if torn; from beer; returns from least chagrin; < from sitting, lying, in cold, > warmth and motion.

Amelioration. - Warm, dry weather, wrapping up; warm or hot things; motion; change of position; moving affected parts. The great characteristic or Rhus is that with few exceptions the pains occur and are < during repose and are > by motion. Sepia, often quickly > itching and burning of Rhus, the vesciles drying up in a few days. Rhus is best antidoted by the simillimum; the potentized remedy given internally. The dermatitis should never be treated by topical medicated applications; they only suppress, never cure.

This is the third remedy of our so-called restless trio. This restlessness of Rhus is on account of the aching pain and soreness which is temporarily relieved by movement. There is also an internal uneasiness which is purely nervous, which causes the patient to want to be on the move, even when there is no particular pain present; but not nearly to the degree that we find it under Aconite and Arsenicum.

As in Bryonia, so in Rhus, the leading characteristic is found in its modality. The aggravation on movement, in the former, is no less marked than the aggravation when quiet of the latter. The patient tosses and turns from side to side with Rhus the same as with Aconite and Arsenicum. With Rhus the change relieves, while with the other two it does not. In Bryonia, the more the patient moves the more he suffers, while with Rhus, the more and longer he moves the better he feels, until he is exhausted. In acute affections, like scarlatina and typhoid fevers, and even in the hot stage of intermittent fever, constant movement seems to be the patient's only relief. With chronic diseases like chronic rheumatism the patient must move, suffers on first beginning to move, but as he continues to move, or as he expresses it, "gets limbered up", he feels better. But he cannot long lie comfortably in either the acute or chronic trouble, for the aching comes on and he must move even if it does hurt him at first. The pains causing the restlessness of Rhus are not so agonizing as they are under Aconite and Arsenicum, nor is the prostration so great as under Arsenicum nor the excitement so great as under Aconite. Rhus and Arsenicum are often indicated in typhoids, Aconite seldom or never, but all three are equally restless remedies.

If in genuine typhoid Arsenicum, as some think, heads the list, because oftenest indicated, Rhus will put in equally strong claims in all other diseases that take on typhoid symptoms. The literal meaning of the term or word typhus is smoke, stupefaction. Now in all forms of typhus, known as cerebral, abdominal and pneumo-typhus, taking all together, Rhus will be as often indicated as any other remedy. Whenever in fevers or even inflammatory diseases the sensorium becomes cloudy (smoky) or stupefaction sets in, with low grade of muttering delirium, dry tongue, etc., we think of Rhus. Dry or dark coated tongue, with triangular red tip, is especial indication for this remedy. This condition of sensorium and tongue may appear in dysentery, peritonitis, pneumonia, scarlatina, rheumatism, diphtheria; bilious, remittent, typhoid fevers, etc. It makes no difference what the name or locality of the disease is if the symptoms are there. The stupefaction calling for Rhus in these diseases is not so profound as that calling for Hyoscyamus or Opium, but is more on a parallel with such remedies as Baptisia, Nux moschata, Lachesis or Phosphoric acid. Nor is the delirium so violent as that calling for such remedies as Belladonna, Hyoscyamus and Stramonium. Both stupefaction and delirium are mild in form, but regular and persistent. Of course the Rhus restlessness is present and the patient tosses or turns from side to side, even without knowing of it, or of anything going on around her. She will answer questions and perhaps answer correctly, but afterwards does not know anything that transpired while she was sick, may be for days or weeks.

Rhus, Baptisia and Arnica closely resemble each other; and choice is sometimes difficult; but we will try to differentiate them when we come to write upon the two latter.

Cough during chill in intermittents is a characteristic given us by Carroll Dunham, and is very reliable, as I have had occasion to prove.

Rhus acts particularly on fibrous, muscular and cellular tissues. The muscles are stiff and sore. This may be of a rheumatic character, or may have been induced by straining, by heavy lifting or severe muscular exercise of any kind, or it may have been brought on by exposure to cold, especially wet cold.

This strained condition may not be confined to the muscles alone, but may involve the tendons, ligaments and membranes of the joints. Several affections of the muscles of the back and even the spinal membranes (myelitis) may come on from sprain, or by exposure, by sleeping on damp ground, or in bed with damp sheets, or getting wet in a rain storm, especially while perspiring. Indeed Rhus is one of our best remedies in lumbago. But it makes no particular difference what muscles are strained or exposed so as to bring on this lameness and soreness the remedy is the same, and if the great characteristic – "Lameness and stiffness and pain on first moving after rest, or on getting up in the morning, relieved by continued motion", is present, Rhus is the first remedy to think of.

Rhus is also often a remedy for glandular swelling of parotid or submaxillary glands during scarlatina, cellulitis in diphtheria, or orbital cellulitis.

This is also one of our best remedies in skin diseases. No one who has been poisoned by it will doubt that Rhus has power to produce skin disease, and of course in accordance with our law of cure we would expect cures by it. We have not been disappointed. The eruption of Rhus poisoning is vesicular. Erysipelas of the vesicular variety, accompanied by the restlessness and sensorium of this remedy, is quickly cured by it. So, also, is scarlatina. If we find the skin red, smooth and shiny, with high grade of fever and delirium Rhus would not do any good, but Belladonna or some remedy having that kind of skin, etc.

Apis, Cantharis, Lachesis, Ailanthus and others have each their peculiar appearance of the skin in these acute exanthemata. Yet, notwithstanding this, it must be remembered that in many cases the leading indication for a remedy will not lie in the skin symptoms, but outside of them.

If in variola the eruption turns livid and typhoid symptoms supervene we may rely on Rhus for a good effect. Probably no remedy is oftener found useful in herpes zoster than this.

Rhus is no less valuable in chronic skin troubles than in acute. Eczemas of the vesicular type are often cured by it; there is much itching which is not greatly relieved by scratching. In all such cases of course the constitutional symptoms weigh as much as the local. So far as dose is concerned, I have used it both high and low, and find it useful all along the scale, but I have an M. M. potency made upon my own potentizer which has served me so well, and so many times, that I cannot refrain from speaking of it.
