Patch 5.0.4 - now heals for 35k (was 26k)[]
I'm not sure of the exact date, but as stated on wowhead and on the forums, this heals for the same amount as 
[Dense Embersilk Bandage]. Confirmed it with the ingame tooltip today also. Will research yellow/green/grey once I have enough. User:VallZ/Sig37 09:05, 5 November 2013 (UTC)
