Agar: The Versatile Seaweed Gel
Overview
Agar, derived from the red algae Gelidium amansii, is a natural gelatinous substance commonly used as a thickening agent, stabilizer, and laxative in food and pharmaceutical products. Its high fiber content makes it beneficial for digestive health, particularly in managing constipation.
Medicinal Activity
Agar exhibits notable pharmacological activities, including:
1. Laxative: Acts as a gentle laxative by adding bulk to the stool, promoting bowel movement.
2. Peristaltic: Stimulates peristalsis, the wave-like muscle contractions that move food through the digestive tract.
