10 Possible Side Effects Of Arctostaphylos Uva-Ursi (Bearberry)

Arctostaphylos uva-ursi has some side effects when used improperly, such as allergic reactions, digestive issues, and interactions with medications.

These side effects can occur due to overconsumption or poor quality of the herb, as well as individual sensitivities.

For instance, a person with a history of kidney problems may experience worsening symptoms if they take bearberry without medical supervision, leading to further complications and decreased quality of life.

This article explains in details the 10 most common side effects of Arctostaphylos uva-ursi if used imporperly.

1. Exacerbates existing medical conditions

Arctostaphylos uva-ursi causes kidney damage due to its high concentration of anthraquinones, which can increase urine production and reduce the ability of the kidneys to concentrate urine.

This can lead to a decrease in blood volume, causing dehydration and further straining the kidneys.

The excessive excretion of electrolytes and water-soluble vitamins may also contribute to kidney damage over time.

2. Exacerbates existing medical conditions

Arctostaphylos uva-ursi triggers allergic reactions due to its high concentration of anthraquinones and flavonoids.

These compounds can cause an immune response in some individuals, leading to symptoms such as hives, itching, and swelling. Additionally, the plant's saponins may contribute to the development of allergic reactions by increasing permeability in the skin and mucous membranes.

The risk of allergic reactions is higher in people with a pre-existing sensitivity or allergy to plants from the same family as Arctostaphylos uva-ursi.

3. Exacerbates existing medical conditions

Arctostaphylos uva-ursi increases risk of bleeding due to its ability to inhibit platelet aggregation and prolong bleeding time.

This is because the plant's active compounds, particularly arbutin and hydroquinone, have anticoagulant properties that can disrupt blood clotting mechanisms.

As a result, people taking Arctostaphylos uva-ursi may experience prolonged bleeding times or excessive bleeding from cuts or wounds.

4. Exacerbates existing medical conditions

Arctostaphylos uva-ursi induces liver problems due to its high concentration of anthraquinones, which can cause inflammation and damage to the liver cells.

Prolonged use or high doses of this herb may lead to liver enzyme elevations, potentially causing liver dysfunction or failure.

Additionally, bearberry's potential interaction with other medications that are metabolized by the liver may further exacerbate liver problems.

5. Exacerbates existing medical conditions

Arctostaphylos uva-ursi interferes with diabetes treatment by reducing blood sugar levels and increasing insulin sensitivity.

This can lead to hypoglycemia (low blood sugar) in individuals with diabetes who are taking medications that lower blood sugar levels.

The berries of the plant contain compounds that slow down the digestion and absorption of carbohydrates, further contributing to this effect.

6. Exacerbates existing medical conditions

Arctostaphylos uva-ursi affects blood pressure control by interacting with certain medications, such as diuretics and beta-blockers.

The alpha-hydroxy acids present in the herb can decrease sodium reabsorption in the kidneys, leading to increased urine production and a potential drop in blood pressure.

Additionally, the herb's ability to relax blood vessels may further contribute to decreased blood pressure levels, which can be problematic for individuals with pre-existing hypertension or those taking medications to manage their blood pressure.

7. Exacerbates existing medical conditions

Arctostaphylos uva-ursi produces gastrointestinal upset due to its high concentration of tannins and alkaloids.

These compounds can cause stomach irritation, nausea, and diarrhea in some individuals.

The bitter taste and astringent properties of the plant may also contribute to this side effect, making it uncomfortable for those who consume it.

8. Exacerbates existing medical conditions

Arctostaphylos uva-ursi disrupts menstrual cycles due to its ability to alter hormone levels in the body.

The plant's anthocyanins and flavonoids may interact with estrogen receptors, causing changes in progesterone and estrogen production.

This can lead to irregular or absent periods, making it challenging for some individuals to predict when their next period will arrive.

9. Exacerbates existing medical conditions

Arctostaphylos uva-ursi leads to kidney stones due to its high concentration of arbutin, a compound that is metabolized into hydroquinone in the kidneys.

Hydroquinone can crystallize and form stones when it accumulates excessively in the urinary tract.

The risk of kidney stone formation increases with prolonged use or high doses of Arctostaphylos uva-ursi, particularly among individuals with pre-existing kidney problems or those who are already at risk for kidney stones.

10. Exacerbates existing medical conditions

Arctostaphylos uva-ursi causes stomach ulcers due to its high concentration of anthraquinone glycosides, which can irritate the mucous membranes in the digestive tract.

These compounds can increase acid production in the stomach, leading to inflammation and ulceration.

Additionally, bearberry's astringent properties can dry out the mucus lining of the stomach, further exacerbating the risk of ulcers.
