DESCRIPTION:
Guelder Rose is a deciduous shrub that typically grows 2–4 meters tall. It features opposite, three-lobed leaves and large, showy clusters of white flowers that bloom in late spring. These are followed by bright red, shiny berries in autumn, which resemble cranberries. While the berries are astringent raw, they become edible when cooked and are rich in bioactive compounds.

USABLE PARTS: Berry

MEDICINAL PROPERTIES:
Guelder Rose berries are rich in antioxidants, vitamin C, and polyphenols. Traditionally used to support immune function, reduce inflammation, and assist with colds and respiratory infections. Bark from the plant has also been used as an antispasmodic in folk medicine.

Raw berries may cause nausea or vomiting if consumed in large amounts. Best consumed cooked. Use with caution in individuals with sensitive digestion.

COMBINING WITH OTHER MEDICINES:
May be blended with elderberry, rosehip, or echinacea in immune-support syrups or jams.


PREPARATION:
Berries are cooked into jams, jellies, syrups, or tinctures. Should always be processed by heating or drying before use.

HARVEST TIME:
Late summer to early fall, once berries are fully ripe, vibrant red, and slightly soft to the touch.

HARVEST METHOD:
Clip berry clusters by hand or shears. Remove stems and clean thoroughly before preserving.

CONSERVATION (STORAGE):
Preserve cooked berries in sterilized jars as jams or syrups. Tinctures should be stored in amber glass bottles in a cool, dark location.
