Cantharis. [Canth]
Cantharis symptoms are usually the first ones inquired after when a case of urinary difficulty presents itself. Its symptoms are clear cut, and should not be confounded with those of any other remedy. There is a persistent and violent urging to urinate, with great tenesmus; the urine is passed only in drops and seems like molten lead passing through the urethra, so intense is the burning.
There is with this, usually an aching in the small of the back. It is often indicated in acute cystitis, gravel and urethritis, the great keynotes being the burning and the tenesmus of the bladder; haematuria also calls for Cantharis under certain conditions.
Baehr doubts that Cantharis is ever suitable to the chronic form of cystitis.
Mercurius corrosivus [Merc-c]
Has tenesmus of the bladder with intense burning. The burning is less, but the tenesmus is greater, than in Cantharis. The passing of the urine drop by drop reminds of Aconite, which has the same symptoms. Aconite, however, is adapted to sudden retention of urine, for as soon as the disease becomes fully localized as an inflammation Aconite ceases to be the remedy. Cantharis and Nux vomica have also a similarity in the frequent fruitless efforts to urinate. In the region of the kidneys there is cutting pain which extends into the abdomen, the bladder and urethra. The most distressing symptom is the constant urging to urinate, even a few spoonfuls of urine in the bladder bringing on this urging, which is accompanied by the terrible distress at the neck of the bladder. This pain is aggravated immediately following micturition, showing that with this drug the trouble is more urethral. The urine itself under Cantharis is of a deep red color, deposits a sediment of mucus and often contain fibrinous casts.
Belladonna, too, is a remedy for painful urination. Hughes says that it is a rarely failing remedy for nervous dysuria.
Apis mellifica. [Apis]
The symptoms of scanty urine always leads one to consider whether Apis is or is not the remedy, for although Apis produces scanty urine there are number of other drugs that will do the same thing. The keynotes for Apis in urinary affections are scanty or suppressed urine, drowsiness, oedema in in various parts, thirstlessness and suffocation on lying down. The urine is dark, highly albuminous, and contains casts, so it is readily seen how Apis may correspond to any form of Bright’s disease. In difficult micturition of children Apis is often a useful remedy. It has frequent desire, with the passage of a few drops at a time. Among other symptoms are great irritation at the neck of the bladder and incontinence of urine. It is also the remedy to be thought of in retained urine or inflamed bladder after abuse of Cantharis.
Apocynum cannabinum. [Apoc]
Apocynum seems to act some what on the kidneys and give rise to various dropsical conditions. It produces a scanty urine, which is light in color, or, as it is given, sherry-colored. Its first effect is to produce a copious diuresis; this is followed by the scantiness of urine which results in dropsy. It also produces an incontinence and may be useful in enuresis. A sinking bruised feeling at the stomach is an indication for its use. it differs from Arsenic and Apis in the fact that it has unquenchable thirst. Arsenic wants little and often, Apis is thirstless.
Berberis vulgaris. [Berb]
Outside of its action on the genito urinary system Berberis is seldom thought of, land it is one of our principal remedies for troubles of this system. It seems to correspond to many symptoms which occur in cases of renal calculi. It has severe tearing pains in the kidneys, not merely backache, but pains deep in the kidneys themselves; these pains extend down the back in the kidneys themselves; these pains extend down the back and down the ureters into the bladder;nor do stop here, for we find cutting pains in the bladder extending into the urethra. These pains in the back and along the ureters are very severe; they are worse stooping, lying or sitting, and relieved by standing. In the bladder they cause a desire to urinate, and the patient is constantly urinating, for the bladder seems imperfectly emptied. The bladder aches. The urine itself is reddish, has a reddish deposit consisting of mucus, epithelium and lithates. It differs from the Pareira brava urine in being more slimy. Another characteristic symptoms of Berberis is pain in the hips while urinating. Coccus cacti has some similar symptoms to Berberis, especially the tearing pains extending from the region of the kidneys, the frequent urging to urinate, the deposits of uric acid and the urine of Coccus cacti is dark. These remedies must be distinguished very carefully as they present many symptoms in common. Berberis has rather more back pains, and seems to act deeper. It is especially indicated in genitourinary troubles, which are due to conditions of atony, or feebleness.
