Guelder rose (Viburnum opulus) is a deciduous shrub that belongs to the Adoxaceae family. It is native to Europe, Asia, and North America and is commonly found in hedgerows, woods, and thickets. The shrub grows up to 4-5 meters tall and has clusters of white flowers that bloom from May to July. The fruit of the plant is a bright red, translucent berry that ripens in late summer and early autumn.
Guelder rose has a long history of use in traditional medicine, particularly in Europe and Asia. The bark, leaves, and fruit of the plant contain various phytochemicals, including viburnin, valerianic acid, and tannins, which have been found to have antispasmodic, analgesic, and anti-inflammatory properties. Guelder rose has been traditionally used to treat menstrual cramps, digestive problems, fever, and headaches.
In addition to its medicinal uses, guelder rose is also used in landscaping and ornamental gardening due to its attractive white flowers and bright red berries. The berries are also used in the production of jams, jellies, and wine. However, it is important to note that the berries are toxic when consumed raw and should be cooked before consumption.
