I read a two-line throwaway statement, cucumbers produce a pulse of salicylic acid to fight off diseases. So, intrigued, I researched which other vegetables do the same, and I was really surprised to find it's quite a few!
Many fruits and vegetables naturally produce quantities of salicylic acid, with berries producing the most. The chemical is also found in some herbs and spices. Fruit and veg containing salicylic acid include:
- Green pepper
That's not all, salicylic acid is used within the plants' system to aid photosynthesis, water and ion uptake, plus if a plant is being attacked salicylic acid can trigger another plants defence mechanisms via chemical charges being released.
I knew that Salix plants contain high amounts of salicylic acid but learning how many other plants do, is really interesting.
So if you are in a pub quiz and they ask the question you are now prepared with the answer.
