I was searching for symptoms after making a connection between intake of white willow bark tincture for back pain and vertigo. I've just seen your Salicylate Factsheet and it all makes sense - especially as I’ve been using Ibuprofen regularly for my chronic back pain made worse by a car accident a year ago.
 
Initially I used a product recommended by the health shop called 7 Solgar. It helped the pain but didn’t agree with me so I switched to white willow bark and have had vertigo for 2 weeks.

I stopped taking all my herbal medicines and the vertigo subsided but came back today after taking white willow bark and then a light bulb came on! Not helped by mixing it all in a nutribullet with fruit!!  Thanks for the article – real help. - Ramesh, UK
