In 2012, Canadian researchers researched the effects of cashew nut plant compounds when used to treat diabetes mellitus. The basis for this is the fact that products of the cashew nut tree have been used to treat various complaints in traditional medicine for a long time. The anti-diabetic properties of parts of the cashew nut plant have been investigated in the muscle fibres of mice and in rat livers in this study. It was found that an extract from the seeds of the cashew nut tree stimulates glucose transportation in the muscle fibres. Extracts from the leaves, bark or cashew apple did not show this effect. The researchers came to the conclusion that the extract from the seeds of the cashew tree increased glucose uptake in the muscles and therefore could be offered on the market as a medically effective health food for people with diabetes mellitus in the future.
