Biologists, botanists and herbalists often use the Latin name when describing a species so that there is no confusion as to which species exactly should be used. When most people think of lingonberry, they think of the small red berry or currant called Ribes rubrum in Latin. The Latin name for the lingonberry bush is Vaccinium Vitis-Idaea . Vaccinium is the general term for berry bushes that do not lose their leaves. It is derived from ‘bacca’ meaning berry and ‘vacca’ meaning cow. Cows love lingonberries. ‘Vitis’ is Latin for ‘grape’. Dutch has a number of folk names for lingonberries: Rode krakelbezie, Bospalm, Lepeltjesheide, Blaadjesheide. In English it is called Cowberry, Foxberry or Worthleberry. The best known name in French is Myrtille rouge and in German the berry is called Preiselbeere or Fuchsbeere.

In addition, it contains medicinal tannins in the form of catechol tannin, pyrogall tannin and gallic acid. It also contains the gallic acid glycoside neomyrtillin. It contains the flavonoids hyperoside, quercetin, isoquercetin, ovicularin and epicatechin. By the way, catecholols also fall under flavonoids.

Lingonberry leaf for cystitis
Arbutin in the lingonberry makes it a mild antiseptic; it expels bacteria in the urinary tract. Urulic acid and bitter substances also contribute to the antibacterial effect. In addition, it is an astringent, which means it works on the mucous membranes; these excrete fewer substances. The tannins act as an anti-inflammatory substance in the urinary tract. Arbutin and various flavonoids provide a diuretic effect; one loses fluid that has accumulated over time in edema or fluid accumulation. Due to the combination of these medicinal effects, herbal therapists can decide to use it for the following indications:
- Benign prostate enlargement that can cause bladder infections due to incomplete urination, causing bacteria to remain behind.
- Prevention of honeymoon cystitis or bladder infection in sexually active women,
- Prevention of repeated bladder infections in the elderly, women with weakened resistance and diabetics,
- Prevention of bladder infections in postmenopausal women who are more susceptible to infections due to the drop in estrogen and the associated thinning of the mucous membranes.
- Prevention of bladder infections in people with catheter, spinal cord injuries and chronic urinary tract infections. In 90% of cases, burning or stabbing pain during urination is reduced, annoying urges disappear and the number of times one has to urinate is reduced.
- Acute bladder infection, burning and having to urinate in small amounts decrease relatively quickly after taking the berries.
- Acute bladder infection without complications involving painful urination, frequent small urination and acidic urine.
Neomyrtylline works by lowering blood sugar levels. That is why lingonberry leaf is recommended in a tea against diabetes mellitus and adult-onset diabetes.
