Only cream that helps arthritis when it gets bad

My husband and I have been using Simply Flower Power Pain Relief & Moisturising Cream for many years. We first discovered it in a souvenir store in the Sherbrooke Forest in the Victorian Dandenong Ranges (Grants on Sherbrooke, Kallista). My husband suffers from arthritis and when it gets really bad, this cream is the only one that helps relieve the pain and he has tried many different lotions, creams and ointments over the years. I use it for a recurrent low back problem with great success. I have also used it for a bad shoulder. We decided to try it when the owner of the souvenir store told us that local people kept coming back for more when they ran out. I now do the same, only I usually buy it on line!
