Snowball bush, Viburnum opulus, is also known by numerous other common names,
including highbush cranberry, (European) cranberry bush, Guelder rose, and cramp bark. It is the last of these common names
that suggest what it's used for and where the medicine comes from.
Viburnum opulus prefers damp, moderately alkaline soils, but
adapts to grow well just about everywhere. If it doesn't occur
naturally in your area, you can plant it in your yard. It's a shrub commonly used in home landscaping. (I got mine at Home Depot.) High in vitamin
C, the berries are similar to cranberries and often substituted for such
in cooking, including making jams and jellies. While considered
edible, when consumed in large quantities they can cause nausea.
Harvest: It is the inner bark of the snowball bush that
is medicinal. It is best harvested after pruning in the spring, before
the leaf buds open. Alternatively, the bark may also be gathered in
the fall, after the leaves change color. It is then dried for
later use.
A decoction of the bark is an alternative to raspberry leaf tea and
ginger for menstrual cramps. It can be used instead of capsaicin cream,
devil's claw, or white willow bark for lower back pain.
Medicinal uses: Historically, cramp bark was used primarily for
relieving menstrual cramps, easing labor and delivery, and preventing
miscarriage. It was also used to a lesser extent in treating mumps,
gallstones, and asthma, and also valued for its use in reducing anxiety
and high blood pressure. It is used similarly to willow for managing
tension headaches. Modern research has demonstrated its efficacy in
treating duodenal ulcers and endometriosis. There are anecdotal reports
of it being useful in treating restless leg syndrome, arthritis,
inflammation, and epididymitis.
When Viburnum is being used to treat menstrual cramps, it is most effective if taken two to five days before cramps begin.
Tincture: Viburnum opulus is tinctured in a 1:5 ratio in 50% alcohol. (One part Viburnum
bark powder by weight to five parts alcohol by volume.) The
recommended dosages range from 30-90 drops, up to four times per day, to
1/4 teaspoon in 4 ounces of water, 2-3 times per day.
Decoction: For relieving painful cramping associated with
menstruation, before it begins and after it ends, three times per day
boil one tablespoon of powdered bark in a cup of water for ten minutes
and drink. For gallstones, four times per day boil 1/2 teaspoon of
powdered bark in one cup of water for ten minutes and drink.
When it comes to menstrual pain, this species is reportedly better for
pain in the back that radiates down to the thighs. A related species, Viburnum prunifolium (black haw), works better for cramps in the pelvic region.
Contraindications: May lower blood pressure. May aggravate tinnitus. Avoid use with blood thinners.
