Part Used: Bark.

Habitat:The ‘Gaitre-Beries’ of which Chaucer makes mention among the plants that ‘shal be for your hele’ to ‘picke hem right as they grow and ete hem in,’ are the deep red clusters of berries of the Wild Guelder Rose (Viburnum Opulus, Linn.), a shrub growing 5 to 10 feet high, belonging to the same family as the Elder, found in copses and hedgerows throughout England, though rare in Scotland, and also indigenous to North America, where it is to be found in low grounds in the eastern United States.
It grows in hedges, scrub and woodland, usually on damp soils.
Description:
Viburnum opulus is a deciduous shrub growing to 4–5 m (13–16 ft) tall. The leaves are opposite, three-lobed, 5–10 cm (2–4 in) long and broad, with a rounded base and coarsely serrated margins; they are superficially similar to the leaves of some maples, most easily distinguished by their somewhat wrinkled surface with impressed leaf venation. The leaf buds are green, with valvate bud scales….CLICK & SEE THE PICTURES

The hermaphrodite flowers are white, produced in corymbs 4–11 cm (2–4 in) in diameter at the top of the stems; each corymb comprises a ring of outer sterile flowers 1.5–2 cm in diameter with conspicuous petals, surrounding a center of small (5 mm), fertile flowers; the flowers are produced in early summer, and pollinated by insects. The fruit is a globose bright red drupe 7–10 mm diameter, containing a single seed. The seeds are dispersed by birds.
The bark is collected chiefly in northern Europe and appears in commerce in thin strips, sometimes in quills, 1/20 to 1/12 inch thick, greyish-brown externally, with scattered brownish warts, faintly cracked longitudinally. It has a strong, characteristic odour and its taste is mildly astringent and decidedly bitter.

Constituents: The active principle of Cramp Bark is the bitter glucoside Viburnine; it also contains tannin, resin and valerianic acid.
Edible Uses:
The fruit is edible in small quantities, with a very acidic taste; it can be used to make jelly. It is however very mildly toxic, and may cause vomiting or diarrhea if eaten in large amounts.

Medicinal Uses: The bark, known as Cramp Bark, is employed in herbal medicine. It used formerly to be included in the United States Pharmacopoeia, but is now omitted though it has been introduced into the National Formulary in the form of a Fluid Extract, Compound Tincture and Compound Elixir, for use as a nerve sedative and anti-spasmodic in asthma and hysteria.

In herbal practice in this country, its administration in decoction and infusion, as well as the fluid extract and compound tincture is recommended. It has been employed with benefit in all nervous complaints and debility and used with success in cramps and spasms of all kinds, in convulsions, fits and lockjaw, and also in palpitation, heart disease and rheumatism.

Crampbark is effective at relieving any over-tense muscle, whether smooth muscle in the intestines, airways, or uterus, or striated muscle in the limbs or back. It may be taken internally or applied topically to relieve muscle tension. The herb also treats symptoms arising from excess muscle tension, including breathing difficulties in asthma, and menstrual pain caused by excessive contraction of the uterus.. For night cramps and back pain, lobelia is often mixed with crampbark. The herb also relieves constipation, colic, and irritable bowel syndrome, as well as the physical symptoms of nervous tension. Useful as a protection against threatened miscarriage. Its astringent action gives it a role in the treatment of excessive blood loss in periods and especially bleeding associated with the menopause. In some cases of arthritis, where joint weakness and pain have caused muscles to contract until they are almost rigid, crampbark can bring remarkable relief. As the muscles relax, blood flow to the area improves, waste products such as lactic acid are removed and normal function can return. Crampbark is commonly used in treatments for high blood pressure and other circulatory conditions.

It is a specific remedy for pains in the thighs and back and a bearing-down, expulsive pain in the uterus, whether during pregnancy and childbirth or during menstruation. Crampbark combines well with bearberry for bladder infections with painful cramping and frequent urination with little passed.

For the relief of cramp it may be combined with Prickly Ash and Wild Yam. For uterine and ovarian pains or threatened miscarriage it may be used with Black Haw and Valerian. For bladder infections with painful cramping combine with bearberry.

Other uses:
The term cramp bark is related to the properties of the bark’s ability to reduce smooth muscle tightness. It is called cramp bark as relieving this type of muscle tightness is most often associated with relieving women’s menstrual (period) cramps. However, this can also be used during pregnancy for cramps or pain and general muscle cramping.

Cultural meaning:
Viburnum opulus (Kalyna) is one of the National symbols of Ukraine.   Mentions of the bush can be found throughout the Ukrainian folklore such as songs, picturesque art, Ukrainian embroidery, and others. Chervona Kalyna was the anthem of the Ukrainian Insurgent Army. Kalyna Country is an ecomuseum in Canada.

This bush’s symbolic roots can be traced to the Slavic paganism of millennia ago. According to a legend Kalyna was associated with the birth of the Universe, the so-called Fire Trinity: the Sun, the Moon, and the Star.  Its berries symbolize blood and the undying trace of family roots. Kalyna is often depicted on the Ukrainian embroidery: towels and shirts. In Slavic paganism kalyna also represents the beauty of a young lady which rhymes well in the Ukrainian language: Ka-ly-na – Div-chy-na. That consistency was reviewed by numerous Ukrainian folklorists such as Nikolay Kostomarov, Oleksandr Potebnia (founder of the Kharkiv Linguistic.
