The konjac plant, also known as Amorphophallus konjac, is a perennial plant native to Asia, particularly in countries like Japan, China, and Indonesia. It is recognized for its large, umbrella-like leaves and a distinctive corm, which is a bulbous underground stem. The plant thrives in warm, humid environments and is often found in forested areas. The corm of the konjac plant is rich in a dietary fiber called glucomannan, which is used in various food products, including konjac noodles and shirataki rice. This fiber is known for its ability to absorb water and promote a feeling of fullness, making it popular in weight management diets.
