Osteoarthritis,my Mum has been told she has this in her knee.?

Does anyone know if there is a herbal supplement,or change in diet that can help this?

It's wear and tear of the joints. She needs to watch her weight, keep her joints moving and take proper painkillers and anti-inflammatories from her GP. Research has shown alternative treatments are of little value. Yes, even glucosamine.

Take cod liver oil for joint pain.
I agree cod liver oil suppliments or fish oil- youan get tehm froma ny good herbal shops or supermarkets
take cod liver oil it oils your joints and stops the joints from crunching.
cod liver oil and also glucosamine sulphate (spelling?) my mum has this and finds these help. Try going to a health food shop or herbal supplement shop and asking the staff, they tend to be very knowledgable about these things :)
i have osteoarthritis in both my knees , not alot you can do , excises is very good , i go to the gym 3 times a week and i am 61yrs old it does help same old adage , use it or lose it, as one gets older things tend to wear out but excises is so very good for a lot of things , i have only been going for 10mths, and have lost 1st and a half too, do not know where you live but my Dr's gave me a prescription for the gym it worked so i joined tell your mum to speak with her doc, hope this helps
