Urinary tract/kidney infections, fluid/urinary retention, cystitis, swelling in the urinary tract, hyperpigmentation, dry hair and scalp, prevention of kidney/gallstones (not my first choice for this, as it isn’t suitable for long-term or frequent dosing – if you suspect you already have stones, consult with a doctor before using any herbal medicine).
The leaves can be made into a tea, tincture or capsules, and even have been smoked in traditional ceremonies.
While uva-ursi is not a common topical remedy, it has been used in external preparations for lightening skin – making it useful for those with hyperpigmentation or scarring. It is also included in some hair care products designed to moisturize the hair and scalp.
May cause stomach upset and vomiting, especially in high doses. Do not use if pregnant or nursing, if you have high blood pressure, thinning of the retina, potassium deficiency, Crohn’s disease (or other digestive disorder), bladder/kidney/gallstones, or an underlying liver or kidney disease. Do not give to children under 18 years old. If taking an iron supplement, do not use uva-ursi within two hours before or after your supplement dose. Do not take supplements or medications that increase urine acidity while on uva-ursi (including Vitamin C, cranberry juice, and others). May interact with pharmaceutical medications, including NSAIDs (such as aspirin and ibuprofen) and lithium. Serious side effects may result if you exceed the recommended dosage.
*Important: The hydroquinones in uva-ursi can be toxic to the liver – do not use in high doses, or for more than five consecutive days, and don’t take more than five courses of treatment with this herb in one year. Do not take with any drugs that are hard on the liver, including alcohol.
I suggest consulting a pharmacist or physician before starting any herbal supplement if you are taking a prescription medication or have serious underlying health concerns.
This herb has an extensive history, being used by First Nations populations as a smoking herb, and of course for medicinal preparations. Particularly when used for smoking, it was referred to as kinnikinnik. It was used to open up energetic channels and facilitate spiritual communications. It was considered particularly appealing for those who have bear as their totem animal. Its constitution is hot, sour and dry.
