Beline is not a herbal medication, it is a combination of corticosteroids, antihistamines and non-steroidal anti-inflammatories that is fraudulently sold as a herbal remedy. That doesn't mean that they're dangerous, or that you should stop taking them, but I'd advise that you chat to your GP and show them the actual ingredients list to see whether or not you should be taking them. The best thing to do for arthritic knees is lose weight and do weight bearing exercise (squats are great for your knees, despite popular opinion). Surely if you have arthritic knees then squats would make things worse. Weight lose and non stressful exercise like a walking or exercise bike.
