Uva ursi
Made from bearberry — the Arctic shrub whose arbutin is a genuine urinary antiseptic, official in pharmacopoeias past and present, and the classical remedy of chronic bladder catarrh.
The whole picture, in one breath
Think of a bladder that chronically complains: persistent urging with mucous, stringy sediment, burning and tenesmus, the urine containing mucus and blood in streaks, in a person whose attacks return with every chill. The chronic mucous cystitis: that is Uva ursi.
The substance, in plain words
Bearberry is the Arctic-Alpine shrub whose leaves carry arbutin — a genuine urinary antiseptic that the body converts to antiseptic hydroquinone in the bladder. Official in pharmacopoeias old and current, sold in European pharmacies to this day. The proving gave the classical chronic-cystitis portrait.
The traditional picture Classical sources
The inner state
- Anxiety with the recurrences. Fear of the returning attacks, worse at night.
- Irritability. Cross, worse in damp weather.
- Despondency. Gloomy in the chronic, winter-returning states.
The body
- Chronic cystitis with mucus. The keynote: persistent bladder catarrh — mucous, stringy sediment, urging, tenesmus.
- Blood and mucus in streaks. The urine passes with streaks of blood and shreds of mucus.
- Burning and tenesmus. Constant burning and the sensation of unfinished business after urination.
- Worse cold and damp. Every chill restarts the catarrh; winter is the enemy.
- Associated symptoms. The books pair it with the chronic catarrhal constitution — throat, bowel, skin.
- Better for warmth Warmth and rest between attacks lengthen the good intervals.

Where it acts (organ affinities)
Bladder and urinary mucosa, urine, general catarrhal constitution.
Where the classical picture comes from
The official urinary antiseptic's career — the bladder's oldest botanical drug — gave the proving its frame; the remedy became the classical portrait of the chronic, mucous, winter-returning cystitis.
The substance in real medicine Pharmacology
What this section is: the pharmacology and toxicology of the source substance. It is not clinical evidence that a homeopathic preparation of it treats any condition. What controlled trials do and do not show is set out on the Evidence page.
Arbutin is a genuine urinary antiseptic: converted to hydroquinone in the bladder, it suppresses bacteria there, and bearberry remains an official medicine in several European pharmacopoeias — a rare classical remedy whose source never left the dispensary. Modern cystitis is, of course, antibiotics after culture; but the bearberry leaf is one of herbal medicine's most legitimate survivors.
Look-alikes (how the classical authors told it apart)
| Remedy | Looks similar because… | Tells it apart because… |
|---|---|---|
| Cantharis vesicatoria | Acute burning cystitis | Cantharis is the acute scalding emergency; Uva ursi the chronic, mucous catarrh. |
| Equisetum hyemale | Bladder irritation | Equisetum's is the tender, touch-me-not bladder; Uva ursi's the mucous, chronic one. |
| Terebinthina | Bladder with systemic signs | Terebinth's is the tympanitic, bloody, systemic cystitis; Uva ursi the chronic mucous one. |
| Benzoicum acidum | Urinary antiseptics | Benzoic acid is the other official urinary antiseptic — for the strong-smelling gouty urine; Uva ursi for the mucous chronic. |
