The medicinal power of bearberry

The bearberry is native to North America, where bears like to snack on the fruits of this shrub. In addition to North America, the bearberry is also found in Scandinavia, Northern Europe, Iceland, Northern Asia and Northern Japan. Textile dyers used bearberry berries to color textiles blue. On Saturday they hung it up; it was initially yellow. Two days later, after oxidation, it turned blue. That was on Monday. The textile workers then had a day off. This fact gave rise to the expression ‘a blue Monday’. NB!

Bearberry naming

In Latin, bearberry is called Arctostaphylos Uva-Ursi . Arctostaphylos is a Latin corruption of the Greek words ‘arktos’ meaning bear and ‘staphylos’ meaning ‘grapes’. ‘Uva’ means ‘berry’ and ‘ursi’ means ‘bear’. Actually, the botanical name is a tautology; it says the same thing twice. The Dutch name bearberry is a translation of the Latin meaning. There are alternative names in Dutch: Zandbezie and Plaskruid. The last meaning is a reference to the medicinal properties of the leaves; a tea made from these leaves reduces the size of a benign prostate enlargement and disinfects the urethra. That makes urination easier.

History of bearberry

Indians living in what is now Canada used bearberry leaves for urinary tract infections, sprains, swellings and irritations. This medicinal plant was first mentioned in English herbal books in the 13th century as a medicine for urinary tract infections. Europeans and Indians had independently discovered the medicinal effects of this plant on the urinary tract. From the 16th century, bearberry leaf has also been mentioned on the continent as a means of treating inflamed urinary tracts. In the mid-18th century, the plant was included in the arsenal of medicinal plants used by university-trained doctors. It ended up in the English Pharmacopoeia, a book with an overview of medicinal plants and their effects. Because bearberry contains many tannins, it was used in leather processing. The leaf was also mixed with tobacco as a seasoning.

Active substances bearberry

The berries are edible but not used for medicinal purposes; only the leaf is used for this purpose. The leaf mainly contains hydroquinone monoglycosides such as arbutin, hydroquinone, methyl arbutin and to a lesser extent piceoside. Furthermore, it contains a little free hydroquinone. Tanning agents are contained in large numbers; ellagitannins, gallic acid and gallotannins. In terms of flavonoids, bearberry leaf contains: hyperoside, isoquercitrin, quercetin, quercitrin and myricetin. It also contains the pentacyclic triterpenes ursolic acid and oleanolic acid. To a lesser extent, bearberry leaf contains: the phenolic acids p-coumaric acid and syringic acid, essential oil, the iridoid monotropeid, allantoin, malonic acid, citric acid, quinic acid, formic acid, the bitter substance ericoline, the resin ursone, the glycoside piceine, vitamins B1, B2, B3 and C, beta carotene, the minerals calcium, magnesium, potassium, manganese, chromium, cobalt, aluminum, iron, phosphorus, selenium, silicon, sodium, tin and zinc, fiber, fats betasitosterol and taraxosterol.

Medicinal effect of bearberry

The main action of bearberry is that it is a mild urinary antiseptic; that is, it disinfects the urinary tract. Arbutin and methylarbutin are the main active substances. Chemical conversions via the liver produce the substance hydroquinone, a substance that, among other things, is antibacterial against the E.coli bacteria. Furthermore, it is an astringent or mucous membrane astringent. It is also a natural painkiller and an astringent. In addition, the tannins present reduce mucosal secretions and it is an anti-inflammatory agent due to the presence of tannins, ursolic acid, hyperoside and arbutin in bearberry leaf. All these medicinal effects make bearberry leaf an excellent remedy for:

Consult the herbal therapist

Bearberry leaf is not well tolerated by everyone, even if it is highly diluted. Bearberry leaves, unlike the fruits, should never be eaten; they contain too many tannins. Bearberry medicine gives urine a greenish color. A herbal therapist will prescribe never to do more than 5 treatments with bearberry per year. Children under 12 should not use it internally. It is also not good for pregnant women to use it. There are a number of contraindications and warnings that the herbal therapist can inform you about.
