Mountain Ash
also known as Rowan Tree  

Here is a Mountain Ash. At around September you will find the berries if the Mountain Ash tree
are ripe and ready to pick. The berries have a bitter sweet taste when eaten on there ow but can
be used to make Jam and is quite nice when used in this way.

I also have eaten these berries with other plants 
to bulk up a salad when out traveling on foot just
as a energy source.

I have come across a reference from a post that some one made that the berries can cause kidney damage due to the parasorbic acid content. It is the first time i have heard of this so i looked it up.

here is what i have found

The biosynthetic incorporation of [1-14C], [2-14C], and [6-14C]-D-glucose, sodum [1-14C] and [2-14C]-acetate, and sodium [1-14C]malonate into parasorbic acid has been studied by use of ripening rowanberries attached to the tree. The distribution of labelling in parasorbic acid has been investigated by extraction and counting of C-1, C-5, and C-6. Results show that formation by alteration of the oxidation level of glucose, with stereochemical amendment but retention of the integrity and congruence of the chain (as occurs in macrolide carbohydrates), could at most be a minor pathway. An acetate–malonate pathway is supported and there is evidence of ‘starter’ and ‘extender’ effects. Comment is made on the absolute configuration of certain related lactones.

I believe that what this is saying is that there are traces of parasrbic acid but only in small amounts, caused by the natural development of the berries and from changes in climatic temperature
