Hello Sparklefizz I have used Rhus Tox and Ruta Cream and found it helpful, but the tubes don't last long. I see that you are buying tubs of Rhus Tox direct from Helios. I've been to their website but can only find the tubes. Are you able to help by sending a link or further information please? Many thanks. 
Hi Aldom Glad it's helping you. I phoned them and asked them as (like you) I couldn't find tubs on their website, but an alternative practitioner friend of mine had suggested I ask.
I buy a 500g. tub for about £20 + p+p. Can't recall exactly how much it cost before but that's the approximate price and the tub lasts for ages and is much better value.
