A species of legumes in Scotland can prevent hunger and thirst for weeks.

>>>Die for poisonous plants in the garden

Lathyrus linifolius (belonging to the legume family) is a plant that looks like a fern and has purple flowers. According to research documents, they were an important ingredient in the diet in the Scottish highlands until about the 18th century, when food sources were scarce.

The bean-sized tubers are separated from the roots and dried. Some tubers can provide the necessary energy and prevent hunger and thirst for a long time. People here are said to have lived on this root when the crop failed.

According to 17th-century documents, monks used this plant to treat patients in the early 14th century, while Julius Caesar's soldiers also ate roots before the 48 BC battle.

Dr. Moffat, head of an archaeological program, said the plant's root has licorice flavor and anise-like aroma. After eating tubers, people will not feel like eating and remember to eat for weeks, even months. The strange sweetness can be transethanol , a sweet substance 300 times more than sugar and can provide energy.

As potato plants are increasingly grown in popularity, the lathyrus linifolius plants are gradually forgotten and have only been discovered in recent research. Experts believe that lathyrus linifolius can be applied in the modern world, improving human fat excess.

An entrepreneur named Richard Swift intends to fund a plan to test the nature of the tree, which is intended to expand in rural Scotland. Richard's goal is to save hunger and maintain energy.
