About Bearberry (Arctostaphylos uva-ursi L.) (kinnikinnick, arbutus, bear-grape, hog cranberry, manzanita, mountain box, mountain cranberry, bountain-box, red bearberry, rockberry)

A perennial, evergreen shrub in the Ericaceae family. The main root is a trunk root, up to several metres long, with light bark and few secondary roots. The adventitious roots are 15-30 cm long, thin, branched, with darker bark. The stem is 5-20 cm long, usually under the alluvium. Old branches are creeping, sturdy, strongly branched, knobbly, scaly, reddish brown, arranged in several tiers. The shoots of the young twigs extend along the ground, forming a rugae. They are slightly hairy at first, sometimes glabrous, light grey-brown. Grows to 2-90 cm long. In the third year it takes root, but the shoots in the rooted part of the bush are no longer than 20 cm. Leaves are stiff, leathery, 0,3-3,2 cm long, 0,2-1,5 cm wide, stiff, obovate-ovate, wedge-shaped, sometimes lanceolate, depending on abundance, with a blunt to slightly concave, less often pointed apex, downwardly curved margins, dark green on the upper side, lighter on the lower side, with sunken reticulate veins. The leaves are smaller in the middle of the shrub than at the margins. The leaf blade tapers into a short, 0,2-0,5 cm long, slightly hairy petiole. The 3-12 flowers are clustered in clusters on the ends of short branches, mainly in the middle of the shrub. The corolla is pink, sometimes white, bulging, ovate-rounded, with a five-pointed recurved pink ledge, hairy inside. Stamens 10, pistil 1. Fruit a red or orange glossy berry flattened at the ends (mealy stone fruit). Seeds 5, brown, hard, often adult. Flowering May-June. Fruits ripen in August-October.

Active ingredients. The leaves of horseweed contain 6-14% arbutin, 10-25% tannins, 6% terminal, 0.4-0.75% ursolic acid, formic, ellagic acids, about 200 mg% vitamin C, 0.01% essential oil, 0.48-1.1% flavonoids: hyperoside, quercetin, isoquercetin, isoquercetin, myricetrin, quercitrin, isoquercitrin, isoquercetin, and myricetin.

Horseheads Preparation. Medicinal leaves (Uvae ursi folia). They are harvested in early spring, before the buds have burst or begun to burst, and in the second half of summer, after the first-year leaves have grown. Shallow branches are cut off with sharp spades or other tools, leaving at least 1/3 of the stem. Branches with blackened leaves are picked out and the quality raw material is dried in shelters or in hacks. Once dry, the leaves are cut off with light pruning shears or wooden threshing shafts, and the crumbled leaves, forks and other impurities are removed using a rasp or threshing machine. The dried leaves are brittle, odourless and bitterly astringent. 1 kg of fresh leaves yields 200-220 g of dry leaves. Suitable for consumption up to 5 years.

Usage. Preparations of the leaves of Horseweed are used to disinfect the ureters and to stimulate urine output in cases of inflammation of the ureters and bladder.

Contraindications. Horseweed should not be used if there are defects (strictures) in the ureters, if the patient is prone to vomiting and diarrhoea, or during pregnancy.
