I read the article "Changes in Temperature, Texture, and Structure of Konnyaku (Konjac Glucomannan Gel) During High‐pressure‐freezing."

Based on available evidence, the U.S. Food and Drug Administration has determined that the scientific evidence suggests that glucomannan can help reduce blood cholesterol.

The bulbs contain a mucilaginous carbohydrate called glucomannan, which the orchids use to retain water during dry periods.
