| Cuprum is for any spasmodic pain that begins and ends suddenly. It is one of the greatest antispasmodic painkillers. The convulsive spasms (anywhere in the body-stomach, abdomen, chest, or a spasmodic cough) are so strong that the person clenches his fist while the face can be blue. Cuprum is a great help for those unbearable, dry whooping like coughs which improve only by drinking small sips of cold water. It is also a great help for severe cramps in the calves (charley horses) in elderly people at night.
