When recently visiting Darwin on the Sea Princess I spotted the Kakadu Blue stand in the cruise ship terminal. After talking with the lady about the ache in my knee she sat me down and massaged the massage oil into my knee and down my leg. I thought I'll give it a try as I've tried all the over the counter anti-inflammatory creams so bought the $30 massage oil. Since returning to Sydney I have been applying the massage oil twice a day. It certainly relieved the aching I was experiencing. It may not help everyone but it has certainly helped me. I'm glad I came across this natural product.
