Konjac or Stanley’s water-tub is the same type of herbaceous plant as Taro. It has been consumed as food for a long time, especially in Japan.
The Japanese believe that the starch from Konjac, when eaten, help to clean the intestine. It originates from Mt. Himalaya, China, Japan, Indochina, and Philippines. The active ingredient that is commercially product is glucomannan. It is a long-chain carbohydrate consists of glucose, mannose, and fructose. A recent research found that glucomannan provides low calories. The viscosity of this substance decreases the absorption of glucose from the intestine. It is, therefore, suitable for weight-controlling people.
