Early rhubarb

quoteNow here is the science bit:

The poison in rhubarb leaves is oxalic acid. It is found only in small quantities in the leaf stalks, the bit we eat. I'm sure you all know the effect that oxalic acid has on the digestive system

Throughout the growing season the oxalic acid content in all parts of the plant gradually increases. Therefore, rhubarb picked later in the season say from mid June onwards will have a more..... drastic... effect on the tum AND THE BUM AUNTY

Did I read somewhere that the leaves can be boiled and used as an organic insecticide as well? Or am I being thick again? :oops:

Oxalic acid is a strong oxidising agent and acts in a similar way to bleach. I certainly wouldn't like to be sprayed with it :evil:
