Didn't read the description properly. I'd searched for "cooling leg gel" which I wanted for my restless leg problem and sent off for it. It was only after receipt that I realised it was a product for horses. However, I thought if its ok for horses its probably ok for me so tried it and it works to cool my knees and stops the restless legs a treat. It is far bigger than the other product I'd used but couldn't find to replace and great value for money in comparison. Quite a strong "menthol" smell when using it but quickly disappears when rubbed in.
All in all I am quite happy with the mistake I made.
