The cucurbit that has been flourishing has set some fruit and it looks like it is
a horned melon:
I am not sure where I got this plant from - maybe our garden club (TSGS)
as a member gave a talk about it last year.
We have never eaten it but it will be on the menu as soon as it ripens.
According to Wikipaedia this may be the original melon type and it is still
used in Africa as a food item. As a general rule I recommend the food groups that humans ate as we evolved in Africa ( as Homo erectus and then Homo sapiens) as logically our metabolism is best adapted to such foods. This certainly falls into that category.
Pubmed has one abstract (the full article is also available) which reports that the pulp of this fruit has a hypoglycaemic (glucose reducing) effect in diabetic rats.
Generally such a finding is transferable to humans.
