High Bush Cranberry (Cramp Bark)

Viburnum edule, opulus, trilobum

MEDICINAL USES:

The bark is an antispasmodic, a nervine, sedative, tonic, astringent and diuretic.  Cramp Bark’s primary use, as the name suggests, is to give relief from cramps of all kinds, from asthma to periods to pregnancy. Some herbalists claim that it can prevent cramps in pregnancy entirely, if used daily for the last 2 or 3 months of gestation.

Cramp Bark will relax the ovaries and uterus, and so relieve painful cramps associated with menstruation (dysmenorrhea). The same sedative and antispasmodic action can be useful in preventing miscarriage, especially when highly-strung nerves are part of the problem.  Its astringent action gives it a role in the treatment of excessive blood loss during menstruation and especially bleeding associated with menopause.  It is a highly esteemed as a tonic to the female reproductive system in general.

King's Dispensatory describes it as a "powerful antispasmodic", recommending it use in cramps, spasms, asthma, hysteria, cramps of the limbs, convulsions and threatened miscarriage during pregnancy, hysteria, dysmenorrhea, spasmodic contraction of the bladder, spasmodic stricture. The authors recommend the use of V. opulus for: cramps; uterine pain, with spasmodic action; pain in thighs and back; bearing down, expulsive pains; neuralgic or spasmodic dysmenorrhea and as an anti-abortive.  The tincture makes a good liniment to use in relieving cramps.

Cramp bark can help to relieve intestinal cramps and can be effective as well for other types of muscle cramps such as back spasms.  It can help in cases of orchitis and fallopian endometriosis pain and has been used as part of a treatment for irritable bowel syndrome. 

Nervous conditions of all kinds often respond well to Cramp Bark because of its sedative and antispasmodic properties.  It combines well with valerian to ease general tension.  The dosage for tea is 2 tsp per cup, simmered for 10-15 minutes.  Of the tincture, take 30 to 60 drops  (1/2 to 1 tsp).

Cramp Bark may also be used both internally externally to relax tense muscles
