Therapeutics and Pharmacology: Viburnum
opulus is a specific
remedy for visceral tensions. It helps to relax muscular tension and spasm and
is primarily used in the treatment of muscular cramps and ovarian and uterine
muscle problems. It relaxes the uterus and relieves the painful cramps associated
with menstruation. It may also be used in 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. It may also be used to help quieten convulsive states in
children. It relaxes the cardiovascular system in hypertension and eases
constipation associated with tension. Applied externally, it relieves skeletal
muscle tension or cramps. It may also be helpful in some cases of migraine.
Combinations: This herb may be combined with Dioscorea and Zanthoxylum in cramp; and with Viburnum prunifolium and Chamaelirium or Valeriana in threatened miscarriage or uterine pains. It may be added to digestive remedies for irritable bowel, or combined with Juglans or Rheum palmatum for constipation caused by tension.
