(chiefly of a drug) used to relieve spasm of involuntary muscle.
An antispasmodic (synonym: spasmolytic) is a pharmaceutical drug or other agent that suppresses muscle spasms.
One type of antispasmodics is used for smooth muscle relaxation, especially in tubular organs of the gastrointestinal tract. The effect is to prevent spasms of the stomach, intestine or urinary bladder.
Peppermint oil has been traditionally used as an antispasmodic, and a review of studies on the topic found that it "could be efficacious for symptom relief in IBS" (as an antispasmodic) although more carefully controlled studies are needed. A later study showed it is an effective antispasmodic when test-applied topically to the intestine during endoscopy.
Bamboo shoots have been used for gastrointestinal and antispasmodic symptoms.
